But it requires immediate action. That is the message from various European academies, including the Royal Academy of Engineering Sciences (IVA), which has been commissioned by the European Commission to provide advice on how to facilitate the energy transition  in Europe.</b></p>​<img src="/sv/styrkeomraden/energi/nyheter/PublishingImages/filipj.jpg" alt="Filip Johnsson" class="chalmersPosition-FloatLeft" style="margin:5px" /><span style="background-color:initial"><strong>&quot;Our report shows </strong>big challenges but also significant opportunities in the transformation of the energy system&quot;, says IVA fellow Filip Johnsson, professor of Energy Systems at Chalmers, one of the experts behind the advice prepared for the European Commission. </span><div><br /></div> <div><strong>On 29 June 2021</strong>, the European Commission’s Scientific Advice Mechanism publishes two major documents on a systemic approach to the energy transition in Europe: </div> <div><ul><li>​An Evidence Review Report from SAPEA presents the latest scientific evidence and a series of evidence-based policy options.</li> <li>The Group of Chief Scientific Advisors’ Scientific Opinion, informed by this evidence, presents key policy recommendations.</li></ul></div> <div><strong>The expert group emphasises</strong> that the transition to sustainable energy is not just a technical challenge. To enable the transition, a huge systemic problem must be solved by coordinating investment, consumption, and behavior across Europe. This means transforming the entire European energy system — a change which will affect every part of our society and require huge investment during the transition. And we already need to accelerate progress if we want to achieve the EU’s target of net zero emissions by 2050.</div> <div><br /></div> <div><strong>“Thanks to the enthusiastic</strong> engagement of top experts from academies across Europe, both within Euro-CASE and across many other disciplines represented within the SAPEA consortium, we are able to present this comprehensive report to the European Commission.

In three new Chalmers projects, the solar eclipse on 10 June gave young people extra access to space and to science. But not without a bit of luck with the weather, technology and social distancing.</b></p>​<span style="background-color:initial">One of the sky’s biggest events of the year began at 11:30 on the second Thursday in June, when the moon slid gently in front of the sun, a partial solar eclipse visible from Gothenburg and many other places. The event was also an important part of three different initiatives, in three different places, all with the aim of giving young people extra science capital, with the help of Chalmers. </span><div><br /><span style="background-color:initial"></span><div>In all three locations, plans had been changing, right until the last minute. This was the moment of truth for two school classes and their teachers, a handful of Chalmers students, several radio astronomers and two unsuspecting telescopes.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Centrum/Onsala%20rymdobservatorium/340x/lovgardet_solf_lank_72dpi_340x340.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><br /></div> <div>On the stone steps to the playground at the Lövgärdesskolan, a school on the north side of Gothenburg, the entire year 4 gathered to look at the eclipse. They were well prepared. Science teacher Catrine Berglund had sneaked in micro-lessons about space throughout the spring term, and students had painted space motifs on corridor walls to add to the excitement. And the day before, Robert Cumming from Onsala Space Observatory had delivered two &quot;sun cradles&quot; for projecting the sun safely.</div> <div><br /></div> <div>The school had also bought in special eclipse glasses for the whole class - useful for anyone who wants to look at the sun. But the clouds looked dishearteningly dense and grey. Would the sun come out at all?</div> <div><br /></div> <div>In Slottsskogen Park in central Gothenburg, another group gathered: a handful of students in the newly started network Upprymd. During the spring, they had met over Zoom to be trained in public engagement about space. Now getting to know each other in person for the first time, they could start their mission as communicative astronomers.</div> <div><img src="/SiteCollectionImages/Centrum/Onsala%20rymdobservatorium/340x/slottsskogen2_72dpi_340x340.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><span style="background-color:initial">​</span></div> <div>Equipped with binoculars and a cardboard screen, the plan was to show the eclipse to other park visitors. Here, clouds and eye protection were part of the challenge. How could they balance keeping a good corona-safe distance, but at the same time being open and friendly?</div> <div><br /></div> <div>South of the city, at Onsala Space Observatory, Robert Cumming and Eskil Varenius took the opportunity to try a new way of viewing the solar eclipse with the observatory's smallest radio telescopes, SALSA, as part of a third project, “SALSA for years 7-9”, funded by the Swedish Research Council. With an improved user interface, SALSA is currently being adapted to make radio astronomy projects possible for students in their younger teens. </div> <div><br /></div> <div>Here, at least, the weather wasn’t a problem. Radio telescopes can see the sky through thick clouds, and SALSA is no exception. But they had never been used before to see a solar eclipse, and the software was also brand new and untested. On top of that, the plan was to show SALSA live on a link for the school in Gothenburg. Would it really succeed?</div> <div><br /></div> <div>And just where had the sun got to? The wait was nervous in all three places. Gaps finally appeared in the clouds, first in Onsala, then over the park, and finally also at the schoolyard, but those moments were few and easy to miss.</div> <div><br /></div> <div>There! The round disk of the sun, clearly with a chunk missing! For those who got a look, it really was a moment to remember. </div> <div><img src="/SiteCollectionImages/Centrum/Onsala%20rymdobservatorium/340x/salsa_solf_20210610_72dpi_340x277.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /></div> <div><br /></div> <div>The kids on the school stairs didn’t all see the eclipse, but everyone had experienced something out of the ordinary. A reporter from local radio station was on hand to broadcast live, and young enthusiasts Amina and Huzaifa and their friends got to explain the phenomenon to the listeners. In the city park, the students chose eclipse glasses over projection as the best way to share the sight of the cloud-shrouded eclipse, but everyone was satisfied in the end. In Onsala, the measurements clearly showed that the moon really had blocked some of the sun’s radio waves - the experiment was successful. Network issues affected the live connection to the school (and to some extent also the observatory's high-tech reputation). But contact was made and everyone got to say hi.</div> <div><br /></div> <div>After almost two hours, the sun was back to being whole again and it was all over for this time. However, all three projects will continue during the rest of the year. At the school, a special space day is planned for 23 September 2021. For the student network Upprymd, there will be online question and answer sessions with school classes and other events. They’ll also test SALSA and its new software, and start to help school students and teachers make their own radio observations.</div> <div><br /></div> <div>For the solar eclipse over western Sweden we’ll have to wait until 25 October 2022. What are we going to come up with for that? With a bit more science capital to spare, there will be new opportunities for everyone.</div> <div>The project with Lövgärdesskolan is run in collaboration with the City of Gothenburg, the housing company Poseidon and space industry company CAES (Cobham Gaisler).</div> <div><br /></div> <div>Text: Robert Cumming</div> <div><br /></div> <div><em>Images:</em></div> <div><em><br /></em></div> <div><em>A (top) </em><span style="background-color:initial"><em>Johannes Reldin photographed the eclipsed sun through the mesh of one of the SALSA antennas. </em></span></div> <em> </em><div><br /></div> <div><em>B </em><span style="background-color:initial"><em>S</em></span><span style="background-color:initial"><em>ALSA and Robert Cumming on a live </em></span><span style="background-color:initial"><em>link from Onsala with year 4 students.

That is the finding of new research from Chalmers University of Technology, Sweden, looking at emissions from the entire life cycle – from manufacture of electric cars and batteries, to electricity used for operation. However, the total effect of a phasing out of fossil-fuelled cars will not be felt until the middle of the century – and how the batteries are manufactured will affect the extent of the benefit. </b></p>​<span style="background-color:initial">A rapid and mandatory phasing in of electric cars could cause emissions from Swedish passenger cars' exhausts to approach zero by 2045. The Swedish government has proposed an outright ban on the sale of new fossil fuel cars from the year 2030 – but that alone will not be enough to achieve Sweden’s climate targets on schedule. </span><div><br /><div><img src="/SiteCollectionImages/Institutioner/SEE/Nyheter/Johannes-Morfeldt-foto-Abel-Buko.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />“The lifespan of the cars currently on the roads and those which would be sold before the introduction of such a restriction mean that it would take some time – around 20 years – before the full effect becomes visible,” says Johannes Morfeldt, researcher in Physical Resource Theory at Chalmers University of Technology and lead author of <a href="">the recently published scientific study</a>.</div> <div><br /></div> <div>To have the desired effect, a ban would either need to be introduced earlier, by the year 2025, or, if the ban is not brought in until 2030, then the use of biofuels in petrol and diesel cars needs to increase significantly before then – in accordance with the revised Swedish “<a href="">reduction obligation</a>”. The combination of these two measures would have the effect of achieving zero emissions from passenger vehicles and keeping to Sweden’s climate targets. </div> <div><br /></div> <div>“The results from our study show that rapid electrification of the Swedish car fleet would reduce life cycle emissions, from 14 million tonnes of carbon dioxide in 2020 to between 3 and 5 million tonnes by the year 2045. The end result in 2045 will depend mainly on the extent to which possible emission reductions in the  industry are realised,” says Johannes Morfeldt.</div> <div><br /></div> <div>A transition from petrol and diesel cars to electric cars will mean an increased demand for batteries. Batteries for electric cars are often criticised, not least for the fact that they result in high levels of greenhouse gas emissions during manufacture. </div> <div><br /></div> <div>“There are relatively good opportunities to reduce emissions from global battery manufacture. Our review of the literature on this shows that average emissions from global battery manufacture could decrease by about two thirds per kilowatt hour of battery capacity by the year 2045. However, most battery  takes place overseas, so Swedish decision-makers have more limited opportunities to influence this question,” says Johannes Morfeldt.</div> <div><br /></div> <div>From a climate perspective, it does not matter where the emissions take place, and the risk with decisions taken at a national level for lowering passenger-vehicle emissions is that they could lead to increased emissions elsewhere – a phenomenon sometimes termed ‘carbon leakage’. In this case, the increase in emissions would result from greater demand for batteries, and the risk is thus greater the higher the emissions from battery production.</div> <div><br /></div> <div>In that case, the Swedish decision would not have as great an effect on reducing the climate impact as desired. The life-cycle emissions would end up in the upper range – around 5 million tonnes of carbon dioxide instead of around 3 million tonnes. Due to this, there may be reason to regulate emissions in both vehicle and battery production, from a life cycle perspective.</div> <div><br /></div> <div>“Within the EU, for example, there is a discussion about setting a common standard for the manufacture of batteries and vehicles – in a similar way as there is a standard that regulates what may be emitted from exhausts,” says Johannes Morfeldt.</div> <div><br /></div> <div>But, given Sweden’s low emissions from electricity production, a ban on sales of new fossil-fuel cars would indeed result in a sharp reduction of the total climate impact, regardless of how the  industry develops.</div> <div>The results of the study are based on Swedish conditions, but the method used by the researchers can be used to obtain corresponding figures for other countries, based on each country's car fleet and energy system. The year 2045 is highlighted because that is when greenhouse gas emissions within Sweden should reach net zero according to the climate policy goals of the country.</div> <div><br /></div> <div><span style="color:rgb(33, 33, 33);font-family:inherit;font-size:16px;font-weight:600;background-color:initial">More about the research:​</span><br /></div> <div>The scientific article &quot;Carbon footprint impacts of banning cars with internal combustion engines&quot; has been published in Transportation Research Part D: Transport and Environment.

That question is in focus for astronomer Rubén Fedriani at Chalmers. In record-breaking competition, he has recently received a Marie Sklodowska-Curie Action Individual Fellowship. Rubén explains how the fellowship will help him answer the question and why he considers the massive stars to be the rock stars of the universe.</b></p><div><img src="/SiteCollectionImages/Institutioner/SEE/Profilbilder/ruben_fedriani_170.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />– I feel extremely honoured to have received this Marie Skłodowska-Curie Action Individual Fellowship. The competition for such fellowships is really high and this year there has been a record number of applications with no less than 11 573 project proposals amongst all disciplines. I am still digesting such fantastic news!</div> <div><br /></div> <div><strong>Do you have specific plans for your fellowship?</strong></div> <div><br /></div> <div>– The main goal with this fellowship is to boost my career development by conducting cutting edge research in the superb star formation group at the Chalmers University of Technology. With this opportunity, I also hope to disseminate my work within the scientific community, but also among the general public. I believe outreach is a fundamental component of any researcher’s work.</div> <div><br /></div> <div><strong>Which research question are you focusing on?</strong></div> <div><br /></div> <div>– This project is framed within the processes of star formation. The big question we want to answer is, “how are massive protostars born?” For the last several decades, many brilliant people have contributed to the understanding of massive star formation. Answering this question is not easy and many astronomers are actively working on different aspects of star formation. My hope is to shed some light on the formation mechanisms of massive protostars from an observational point of view using some of the most powerful optical and infrared telescopes in the world.</div> <div><br /></div> <div>– You may wonder why this is important, well, massive stars are the reason for the iron in your blood, the calcium in your bones, and of course, the reason you are reading this! Therefore, understanding how they form is in a way understanding our origins and our place in the Universe.</div> <div><br /></div> <div>– To finish, I like to say that ''massive stars are the rock stars of the Universe - blazing short, intense lives, but with death resonating for generations to come!''<span style="white-space:pre"> </span></div> <div><br /></div> <div>Rubén was one of the Chalmers astronomers participating <span style="background-color:initial">In the Star Hunt project,  the 2020 version of the Nobel Prize Museum's project Help a Scientist, where 1,400 school students helped researchers at Chalmers to gather new knowledge about how stars are born. <a href="/en/departments/see/news/Pages/Starstudded-final-for-Help-A-Scientist.aspx">Read more about the Star Hunt​</a>. </span><span style="background-color:initial"></span></div> <div><br /></div> <div><span style="color:rgb(33, 33, 33);font-family:inherit;font-size:16px;font-weight:600;background-color:initial">More info: </span></div> <div><h3 class="chalmersElement-H3"><span></span><span>The Marie Skłodowska-Curie Actions Individual Fellowships​​</span><span>​</span></h3></div> <div>The fellowships are aimed at experienced researchers looking to give their careers a boost by working abroad. <a href="">Read more about the fellowships​</a>.</div> <h3 class="chalmersElement-H3"><span>Protostars</span></h3> <div><p class="chalmersElement-P"><span>A protostar is a very young star that is still gathering mass from its parent molecular cloud. </span><span><a href="">Read more about protostars</a>. </span></p></div> <div><span style="color:rgb(33, 33, 33);font-family:inherit;font-size:16px;font-weight:600;background-color:initial"><br /></span></div> <div><span style="color:rgb(33, 33, 33);font-family:inherit;font-size:16px;font-weight:600;background-color:initial">Image cr</span><span style="color:rgb(33, 33, 33);font-family:inherit;font-size:16px;font-weight:600;background-color:initial">edits: </span><span style="color:rgb(33, 33, 33);font-family:inherit;font-size:16px;font-weight:600;background-color:initial">​</span><br /></div> <div> <div><span style="background-color:initial">Top image: ESA/Hubble &amp; NASA, J.

A major challenge for the textile and fashion industry, however, is how to recycle polyester blends and other synthetic and soiled materials. A new project at Chalmers investigates thermochemical recycling of mixed synthetic textiles, in order to create new materials and fibers. The first tests bode well. </b></p><div>​<span style="background-color:initial">– We are investigating how textiles consisting of fiber mixtures can be recycled thermochemically in a plastics recycling refinery. These materials can’t be fiber recycled with reasonable effort today, and most of it is incinerated, says Martin Seemann, project manager and associate professor at Energy Technology, Chalmers.</span></div> <div> </div> <div><br /></div> <div>Thermochemical recycling means that the molecules are recycled from textiles instead of whole textile fibers. The small molecules can then be used as a recycled raw material to produce new valuable base chemicals and materials, both as a base for new textile fibers and other materials where fossil base chemicals are used today.</div> <div> </div> <div> </div> <div> </div> <div><br /></div> <div> </div> <div> </div> <div> </div> <div>In the process, the textiles are heated up to 600-800 degrees, which in short means that the material is divided into a liquid and a gaseous fraction. The liquid fraction becomes building blocks for new material and the gas fraction can be used to reconnect the building blocks.</div> <div> </div> <div> </div> <div> </div> <div><br /></div> <div> </div> <div> </div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/SEE/Nyheter/martin-seemann-220.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />– This means that you can use basically all of the material to create new fibers. But it is something we will evaluate and test in the project. And with a reasonable effort of, for example, energy. It is about finding the optimal point in this process and if there is a procedure that is more advantageous than the alternatives, says Martin Seemann.</div> <div> </div> <div> </div> <div> </div> <div><br /></div> <div>The textiles that are investigated in the project &quot;Recycling of reject streams from textile sorting and cardboard recycling&quot;, are those that cannot be recycled on a large scale and cost-effectively with other technologies today. The main focus is to get as much useful material out of the process as possible. Then the material could be used as raw material in the textile industry, but also in other industries.</div> <div> </div> <div> </div> <div> </div> <h3 class="chalmersElement-H3">First tests are positive</h3> <div> </div> <p class="chalmersElement-P">In Sweden today, <span>about 7.5 kg of textile per person and year is thrown out with the household trash. There is a proposal for producer responsibility for textiles from 1 January 2024, , in which case the industry will be responsible for collecting this quantity and preparing for recycling. This means that the more than 70,000 tonnes of textiles, which today end up in Sweden's residual waste, will be handled in another way.</span></p> <div> </div> <p class="chalmersElement-P"><span><br /></span></p> <div> </div> <div> </div> <div> </div> <div>At the end of January, the project’s first test was performed with a positive result.

Yes, but not as much as reported last July in a controversial study published in Nature.</b></p><div>​<span style="background-color:initial">The study <a href="">Abrupt increase in harvested forest area over Europe after 2015</a>, used satellite data to assess forest cover and claimed an abrupt increase of 69% in the harvested forest in Europe from 2016. The authors, from the European Commission’s Joint Research Centre (JRC), suggested that this increase resulted from expanding wood markets encouraged by EU bioeconomy and bioenergy policies. The publication triggered a heated debate, both scientific and political, as the EU Parliament and Council were discussing the Post-2020 EU Forest Strategy.</span></div> <div><br /></div> <div> </div> <div><strong>In a response published in Nature</strong>, 30 scientists from 13 European countries have discovered evidence that throws into doubt the conclusions of the JRC study. In Concerns about reported harvests in European forests, Palahí and colleagues demonstrate that the large harvest changes reported by JRC result from methodological errors. These errors relate to satellite sensitivity improving markedly over the period of assessment, as well as to changes in forests due to natural disturbances - for example drought and storm related die-back and tree-falls - being often attributed wrongly to timber harvests.</div> <div> </div> <div><br /></div> <div> </div> <div>Dr Marc Palahí, Director of the European Forest Institute (EFI), who led the response said: “In the future forest information should be more carefully assessed, taking into account a wide variety of methodological issues and factors, before drawing hasty conclusions. This requires enhanced collaboration as well as scientifically robust and common approaches between the European Commission and Member States to enable better informed forest-related policies in the context of the EU Green Deal.”</div> <div> </div> <div><br /></div> <div> </div> <div><strong>“Over the years, we are becoming better</strong> and better at detecting forest loss” said Dr Ruben Valbuena from Bangor University who co-led the study. One of the errors in the JRC study was to underestimate how satellite images, and the methods used to analyse them, have improved over the periods they compared. “Satellite products can only be employed under strict protocols assessing errors, and with better distinction between deforestation and other causes of forest loss”, he said.</div> <div> </div> <div><br /></div> <div> </div> <div>Professor Gert-Jan Nabuurs from Wageningen University, an IPCC lead author who participated in the study, commented that “the harvest across Europe’s forests has increased in recent years, but by just 6%, not the 69% claimed by the JRC study. This is due primarily to a moderate economic recovery after the 2008–2012 recession. What is really striking is the unprecedented levels of natural disturbances affecting our forests in many parts of the continent in recent years.”</div> <div> </div> <div><br /></div> <div> </div> <div><strong>&quot;This scientific critique of the JRC researchers’ </strong>erroneous results is important, and it arrives at the right time as it provides a basis for ongoing policy processes within the EU, such as the taxonomy for sustainable investments and the revision of the Renewable Energy Directive aimed at ensuring that renewable energy effectively contributes to the EU's increased climate ambitions for 2030&quot;, says Göran Berndes, Professor, Biomass and Land Use at Chalmers University of Technology, who, like Nabuurs, participates as lead author in AR6.<br /></div> <div> </div> <div><br /></div> <div> </div> <div><strong>The implications of the errors found</strong> by Palahí and colleagues are of global relevance, as many studies to inform policy-makers and society at large on the state of the world forests are nowadays based on remote sensing. The analysis of products based on satellite imagery is becoming key for instance to understand the extent of global deforestation, and thus we need scientifically robust remote sensing methods for sound policy-making.</div> <div> </div> <div><br /></div> <div> </div> <div><strong>References to mentioned articles:</strong></div> <div> </div> <div><span style="background-color:initial">Palahí, M., Valbuena, R. et al. <a href="">Concerns about reported harvests in European forests.

In a new study, researchers from Chalmers University of Technology, Sweden, and the University of Louvain, Belgium, evaluated over a thousand policy proposals for how the EU could reduce this impact, to assess which would have the largest potential to reduce deforestation – while also being politically feasible.</b></p><div><span style="background-color:initial">“Unsurprisingly, there is weaker support for tougher regulations, such as import restrictions on certain goods. But our study shows that there is broad support in general, including for certain policies that have real potential to reduce imported deforestation,” says Martin Persson, Associate Professor of Physical Resource Theory at Chalmers University of Technology.​</span></div> <div><br /></div> <div><span style="background-color:initial"></span><a href="/en/departments/see/news/Pages/EU-consumption-plays-major-role-in-tropical-deforestation.aspx">Previous research from Chalmers University of Technology has already shown the EU's great impact in this area​</a>. More than half of tropical deforestation is linked to production of food and animal feed, such as palm oil, soybeans, wood products, cocoa and coffee – goods which the EU imports in vast quantities. The question is, what can the EU do to reduce its contribution to deforestation?</div> <div> </div> <div><br /></div> <div> </div> <div>“This issue is particularly interesting now, as this year the EU is planning to present legislative proposals for reducing deforestation caused by European consumption. The question has been discussed by the EU since 2008, but now something political is actually happening,” says Simon Bager, a doctoral student at the Université Catholique de Louvain, Belgium, and lead author of the study.</div> <div> </div> <div><br /></div> <div> </div> <div>The authors of the article mapped 1141 different proposals, originating from open consultations and workshops, where the EU has collected ideas from companies, interest groups and think tanks. The researchers also compiled proposals from a large number of research reports, policy briefs and other publications, where different stakeholders have put forward various policy proposals. After grouping together similar proposals, they arrived at 86 unique suggestions.</div> <div> </div> <div><br /></div> <div> </div> <h2 class="chalmersElement-H2">Two sugg​estions stand out</h2> <div> </div> <div><span style="background-color:initial">Finding proposals for measures that would have the desired effect but are also possible to implement in practice, and enjoy the necessary political support, is no easy task. But after their extensive survey, the researchers identify two policy options in particular which show promise. The first is to make importers of produce responsible for any deforestation in their supply chains, by requiring them to carry out the requisite due diligence.</span><br /></div> <div> </div> <div><span style="background-color:initial"><br /></span></div> <div> </div> <div>“If the importing companies’ suppliers have products that contribute to deforestation, the company may be held responsible for this. We consider such a system to be credible and possible to implement both politically and practically – there are already examples from France and England where similar systems have been implemented or are in the process thereof,” says Simon Bager.</div> <div> </div> <div>“Due diligence is also the measure which is most common in our survey, put forward by many different types of actors, and there is broad support for this proposal. However, it is important to emphasise that for such a system to have an impact on deforestation, it must be carefully designed, including which companies are affected by the requirements, and which sanctions and liability options exist.”</div> <div> </div> <div><br /></div> <div> </div> <div>The other possibility is to support multi-stakeholder forums, where companies, civil society organisations, and politicians come together to agree on possible measures for ridding a supply-chain, commodity, or area, of deforestation. There are positive examples here too, the most notable being the Amazon Soy Moratorium from 2006, when actors including Greenpeace and the World Wide Fund for Nature gathered with soy producers and exporters and agreed to end soy exports from deforested areas in the Amazon rainforest.</div> <div> </div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/SEE/Nyheter/EU-Mercosur-martin-Persson.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />“Examples suc<span style="background-color:initial">h as these demonstrate the effect that multi-stakeholder forums can have. And in our opinion, it is a measure that is easier to get acceptance for, because it is an opportunity for the affected parties to be directly involved in helping design the measures themselves,” says Martin Persson.</span></div> <div> </div> <div><br /></div> <div> </div> <div>Such discussions can also be adapted to the relevant areas or regions, increasing the likelihood of local support for the initiatives.</div> <div> </div> <h2 class="chalmersElement-H2">A delicate ​​balance</h2> <div> </div> <div>The researchers also investigated how to deal with the trade-off between policy impacts and feasibility. An important part of this is combining different complementary measures. Trade regulations on their own, for example, risk hitting poorer producing countries harder, and should therefore be combined with targeted aid to help introduce more sustainable production methods, increasing yields without having to resort to deforestation. This would also reduce the risk of goods that are produced on deforested land simply being sold in markets other than the EU.</div> <div><br /></div> <div> </div> <div>“If the EU now focuses on its contribution to deforestation, the effect may be that what is produced on newly deforested land is sold to other countries, while the EU gets the ‘good’ products. Therefore, our assessment is that the EU should ensure that the measures introduced are combined with those which contribute to an overall transition to sustainable land use in producing countries,” says Simon Bager.</div> <div><br /></div> <div> </div> <div>In conclusion, the researchers summarise three essential principles needed for new measures, if the EU is serious about reducing its impact on tropical deforestation.</div> <div><br /></div> <div> </div> <div>“First, enact measures that actually are able to bring about change. Second, use a range of measures, combining different tools and instruments to contribute to reduced deforestation. Finally, ensure the direct involvement of supply chain actors within particularly important regions, expanding and broadening the measures over time,” concludes Simon Bager.</div> <div><br /></div> <div> </div> <div>The authors hope that the research and identified policy options can serve as inspiration for policy makers, NGOs, industries, and other stakeholders working to address the EU's deforestation footprint. With at least 86 different unique alternatives, there is a wide range of opportunities to focus on the problem – very few of these are political 'non-starters' or proposals which would have no effect on the issue.</div> <div> </div> <div>The full study, Eighty-six EU policy options for reducing imported deforestation is available open-access in the journal One Earth:</div> <div> </div> <div> </div> <div> </div> <h3 class="chalmersElement-H3">For more information, contact:​</h3> <div> </div> <div>Martin Persson, Associate Professor, Physical Resource Theory at Chalmers University of Technology,, +46 31 772 2148</div> <div> </div> <div><br /></div> <div> </div> <div>Simon Bager, Ph.D. candidate UCLouvain and MSCA fellow COUPLED,, +45 2721 7414</div> <div> </div> <div><br /></div> <div> </div> <div><h3 class="chalmersElement-H3"><span>More detailed information regarding how the study was conducted:</span></h3></div> <div> </div> <div>To investigate the potential impact and political feasibility of the 1141 proposals, the researchers first categorised them based on who submitted the proposal, who the policy would affect, and what type of policy is proposed. Since many of the proposals were essentially the same or similar, they were then summarised, resulting in 86 unique suggestions. The majority are based on weaker measures, such as making more information and types of support available to producers, rather than statutory restrictions and regulations on imports and exports. The researchers interpret this as meaning that there is greater support for softer proposals. However, the researchers themselves consider these proposals to be less effective.</div> <div><br /></div> <div> </div> <div>“One example is eco-labelling, where the purpose is to influence consumers to stop buying products that contribute to deforestation. The intent is good, but previous research does not support the argument that this changes consumer behaviour to such a level that production itself is affected. But if import restrictions are instead introduced on goods that are linked to deforestation, it is already known that this has direct effects,” says Martin Persson.</div> <div><br /></div> <div> </div> <div>After evaluating the likely effects, the next step was to see which proposals could actually receive political support, and how complex and costly the formulation and implementation was likely to be. For this evaluation, methodological innovations were required.</div> <div><br /></div> <div> </div> <div>“After categorising the 1141 proposals, we could see how many stakeholders, and of which kind, proposed a certain type of measure. If the same option was proposed by many actors, of different kinds – environmental organisations, companies, and authorities – we interpreted that as strong, broad support for the proposal,” explains Martin Persson.</div> <div><br /></div> <div> </div> <div>The last two steps in the assessment of the measures were then about how complicated and expensive it would be to realise the proposals.</div> <div><br /></div> <div> </div> <div>“For example, commissioning a research institute to investigate, at a detailed level, what drives deforestation – that would be quite easy. But a new tax or punitive duty at EU-wide level would be very difficult and costly to successfully implement. There are some measures, which the EU can take alone, while others require cooperation with the individual member states or third countries. And there we simply rated the institutional difficulty for implementation of each proposal,” says Simon Bager.</div> <div><br /></div> <div> </div> <div>The last aspect for assessing the political feasibility was looking at the economic impact of the proposal.</div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">“If you influence a large impo</span><span style="background-color:initial">rt flow, that will result in major economic consequences.

The observations with the Event Horizon Telescope (EHT) reveal how energetic jets form close to the black hole, 55 million light years distant. Astronomers from Chalmers are part of the international EHT collaboration.</b></p>​<span style="background-color:initial">The Event Horizon Telescope (EHT) collaboration, who produced the first ever image of a black hole, has revealed a new view of the massive object at the centre of the galaxy Messier 87 (M87): how it looks in polarised light. This is the first time astronomers have been able to measure polarisation, a signature of magnetic fields, this close to the edge of a black hole. The observations are key to explaining how the galaxy, located 55 million light-years away, is able to launch energetic jets from its core.</span><div><br /></div> <div>“We are now seeing the next crucial piece of evidence to understand how magnetic fields behave around black holes, and how activity in this very compact region of space can drive powerful jets that extend far beyond the galaxy,” says Monika Mościbrodzka, Coordinator of the EHT Polarimetry Working Group and Assistant Professor at Radboud University in the Netherlands.</div> <div><br /></div> <div>On 10 April 2019, scientists released the first ever image of a black hole, revealing a bright ring-like structure with a dark central region — the black hole’s shadow. Since then, the EHT collaboration has delved deeper into the data on the supermassive object at the heart of the M87 galaxy collected in 2017. They have discovered that a significant fraction of the light around the M87 black hole is polarised.</div> <div><br /></div> <div>“This work is a major milestone: the polarisation of light carries information that allows us to better understand the physics behind the image we saw in April 2019, which was not possible before,” explains Iván Martí-Vidal, also Coordinator of the EHT Polarimetry Working Group and GenT Distinguished Researcher at the University of Valencia, Spain. He adds that “unveiling this new polarised-light image required years of work due to the complex techniques involved in obtaining and analysing the data.”</div> <div><br /></div> <div>Light becomes polarised when it goes through certain filters, like the lenses of polarised sunglasses, or when it is emitted in hot regions of space where magnetic fields are present. In the same way that polarised sunglasses help us see better by reducing reflections and glare from bright surfaces, astronomers can sharpen their view of the region around the black hole by looking at how the light originating from it is polarised. Specifically, polarisation allows astronomers to map the magnetic field lines present at the inner edge of the black hole. </div> <div><br /></div> <div>“The newly published polarised images are key to understanding how the magnetic field allows the black hole to 'eat' matter and launch powerful jets,” says EHT collaboration member Andrew Chael, a NASA Hubble Fellow at the Princeton Center for Theoretical Science and the Princeton Gravity Initiative in the US.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Centrum/Onsala%20rymdobservatorium/340x/eso2105b_72dpi_340x227.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /></div> <div>The bright jets of energy and matter that emerge from M87’s core and extend at least 5000 light-years from its centre are one of the galaxy’s most mysterious and energetic features. Most matter lying close to the edge of a black hole falls in. However, some of the surrounding particles escape moments before capture and are blown far out into space in the form of jets. </div> <div><br /></div> <div><span style="background-color:initial">Astronomers have relied on different models of how matter behaves near the black hole to better understand this process. But they still don’t know exactly how jets larger than the galaxy are launched from its central region, which is comparable in size to the Solar System, nor how exactly matter falls into the black hole. With the new EHT image of the black hole and its shadow in polarised light, astronomers managed for the first time to look into the region just outside the black hole where this interplay between matter flowing in and being ejected out is happening. </span><br /></div> <div><br /></div> <div>The observations provide new information about the structure of the magnetic fields just outside the black hole. The team found that only theoretical models featuring strongly magnetised gas can explain what they are seeing at the event horizon. </div> <div><br /></div> <div>“The observations suggest that the magnetic fields at the black hole’s edge are strong enough to push back on the hot gas and help it resist gravity’s pull. Only the gas that slips through the field can spiral inwards to the event horizon,” explains Jason Dexter, Assistant Professor at the University of Colorado Boulder, US, and Coordinator of the EHT Theory Working Group. </div> <div><br /></div> <div>To observe the heart of the M87 galaxy, the collaboration linked eight telescopes around the world – including the ALMA (Atacama Large Millimeter/submillimeter Array) and APEX (Atacama Pathfinder EXperiment) in northern Chile – to create a virtual Earth-sized telescope, the EHT. The impressive resolution obtained with the EHT is equivalent to that needed to measure the length of a credit card on the surface of the Moon.</div> <div><br /></div> <div>“With ALMA and APEX, which through their southern location enhance the image quality by adding geographical spread to the EHT network, European scientists were able to play a central role in the research,” says Ciska Kemper, European ALMA Programme Scientist at ESO. “With its 66 antennas, ALMA dominates the overall signal collection in polarised light, while APEX has been essential for the calibration of the image.”</div> <div><img src="/SiteCollectionImages/Centrum/Onsala%20rymdobservatorium/340x/eso2105d_72dpi_340x340.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /></div> <div><br /></div> <div>&quot;ALMA data were also crucial to calibrate, image and interpret the EHT observations, providing tight constraints on the theoretical models that explain how matter behaves near the black hole event horizon,&quot; adds Ciriaco Goddi, a scientist at Radboud University and Leiden Observatory, the Netherlands, who led an accompanying study that relied only on ALMA observations.</div> <div><br /></div> <div>The EHT setup allowed the team to directly observe the black hole shadow and the ring of light around it, with the new polarised-light image clearly showing that the ring is magnetised.
