Edenhofer: Shutting down German power stations could have been achieved more cheaply

29.01.2020 - Today, about a year after the report of the so-called Commission, the German government passed the Kohleausstiegsgesetz (Coal Exit Law). Power generation from lignite and hard coal, accounting for 28 percent of gross electricity generation in 2019, shall be stopped by 2038. Lignite operators will receive 4.35 billion euros in compensation; further compensation to hard coal operators will be determined and distributed through auctions. In addition, coal regions will receive 40 billion euros in structural aid.

Germany likely to ramp up CO2 price path

16/12/2019 - Germany is likely to introduce a more ambitious carbon price path than previously envisioned by the Federal government. The mediation committee of the two legislative bodies agreed on a starting price of 25 Euro per ton CO2 in 2021, gradually rising to 55 Euros in 2025. Previously, the German government's plan was to start with 10 Euro, rising to 35 Euro. The national pricing scheme is supposed to complement the European Union's Emissions Trading System. The Green Deal plans just announced by Ursula von der Leyen, President of the European Commission, might also comprise more substantial carbon pricing. On this issue Ottmar Edenhofer, Director of the Potsdam Institute for Climate Impact Research (PIK) and of the Mercator Research Institute on Global Commons and Climate Change (MCC):

COP25 climate summit: "weak outcome"

15.12.2019 - This weekend, the world climate summit COP25 in Madrid ran overtime to come to much debated decisions. Together, the two Directors of the Potsdam Institute for Climate Impact Research issued a statement to comment on the outcome. "This is a minimum compromise," says Earth system scientist Johan Rockström. Climate economist Ottmar Edenhofer adds: "The weak outcome of COP25 is sad but no surprise. It highlights that the next world climate summit in Glasgow really needs to be the turning point it is scheduled to be in the 2015 Paris Agreement timetable."

Edenhofer: "The European Green Deal is a bold plan"

12/12/2019 - The President of the EU Commision, Ursula von der Leyen, today presented the European Green Deal in Brussels. On Thursday, the European Council will debate it. Furthermore, it will be presented at the world climate summit COP25 in Madrid. On this issue, Ottmar Edenhofer, Director of the Potsdam Institute for Climate Impact Research (PIK) said in a statement: "The European Green Deal is a bold plan that must now be followed by concrete action."

Ten PIK researchers among the most influential scientists worldwide: ranking

29.11.2019 - According to a new Clarivate ranking, ten scientists from all research areas of the Potsdam Institute for Climate Impact Research (PIK) are among the most cited researchers worldwide. This places them among the most influential scientists in the world, and their studies rank among the top 1% of scientific literature. Whether natural or social sciences, PIK is among the most renowned research institutions in Germany and worldwide, as the recently published ranking shows.

Schlacke and Edenhofer chair steering committee of “Climate Protection Science Platform” of the Federal Government

22.11.2019 - The Federal Government assigns scientific advisors for the Climate Action Plan 2050. A steering committee consisting of representatives of outstanding research institutions control the “Climate Protection Science Platform". These representatives elected Sabine Schlacke, a lawyer from the University of Münster, and economist Ottmar Edenhofer of the Potsdam Institute for Climate Impact Research and of the Mercator Research Institute on Global Commons and Climate Change as its chairs. As the voice of science, the platform will advise the government on the implementation and further development of the German climate strategy and contribute to the achievement of climate goals. The important aspect here is that it is independent and can act on its own initiative.

From Berlin to New York: United in Science

23/09/2019 - Millions of people all around the globe crowded the streets last Friday, demanding rapid action from policy makers to counter climate risks. The Fridays for Future movement calls upon humanity to "unite behind the science". That very same day, the German government adopted a climate policy package relying on carbon pricing expertise provided by PIK Director Ottmar Edenhofer and colleagues. Yet, the policy package is too weak to meet the climate targets, the expert says. Currently, heads of state are meeting at the UN climate summit – German Chancellor Angela Merkel is one of them. Again, science provides the facts needed for sound decisions. Among other input, PIK Director Johan Rockström presented an "Exponential Roadmap" to sustainability in New York with colleagues. Climate stabilization is both necessary and possible, the science shows.

PIK and MCC deliver detailed assessment of German climate package

14/10/2019 - The climate protection programme adopted by the Federal Government last week, which is intended to limit greenhouse gas emissions especially in the transport and heating sectors, is unlikely to be sufficient to achieve the 2030 climate targets. Policymakers need to make four particular adjustments: first, they need to raise the level of ambition for the carbon price; second, they need to improve social balance; third, they need to develop further its integration with the EU level; and fourth, they need to introduce an effective monitoring process. This is the core message of a detailed assessment of the climate package, presented by the Berlin climate research institute MCC (Mercator Research Institute on Global Commons and Climate Change) and the Potsdam Institute for Climate Impact Research (PIK).

Edenhofer Among 10 Most Influential Economists in Germany

PIK & MCC STATEMENT: “German Government has not delivered”

20/09/2019 - The German government decided today to initiate carbon pricing in the transport and heating sectors. It is to start at 10 euros and gradually rise to 35 euros in 2025. In 2026, the pricing scheme will be converted into a national emissions trading system with a minimum price of 35 euros and a maximum price of 60 euros; how things will continue thereafter shall be determined in 2025. Ottmar Edenhofer, Director of the Mercator Research Institute on Global Commons and Climate Change (MCC) and the Potsdam Institute for Climate Impact Research (PIK), comments:

Edenhofer speaks at CDU and CSU events

09/09/2019 - The two sister Parties of the German conservatives are seeking the expertise of climate economist Ottmar Edenhofer, Director of the Potsdam Institute for Climate Impact Research and the Mercator Research Institute on Global Commons and Climate Change. Prior to the Federal Government's decision on the possible introduction of a national CO2 pricing, Edenhofer was invited as an expert to several events by CDU and CSU, just as he had already presented the state of research to other Parties, ministries and associations. Edenhofer with his team from PIK and MCC has contributed the climatic-economic part of the report on CO2 pricing by the German Council of Economic Experts.

PIK and MCC contribute to Climate Policy Special Report for German government

12.07.2019 - The special report, which the German Chancellor received from the “Five Sages” of the German Council of Economic Experts today, is based to a significant extent on a comprehensive analysis by the Berlin climate research institute MCC (Mercator Research Institute on Global Commons and Climate Change) and the Potsdam Institute for Climate Impact Research (PIK). On Thursday, the so-called Climate Cabinet, with the leaders of the chancellery and six ministries, will discuss a fundamental realignment of climate mitigation measures based on the special report. MCC and PIK Director Ottmar Edenhofer and the Chairman of the Council of Experts, Christoph Schmidt, will present their proposals as scientific advisers at the meeting in the presence of the German Chancellor.

CO2-pricing: German chancellor Angela Merkel visited PIK for a scientific briefing

14/06/2019 - For more than two hours, German Chancellor Angela Merkel visited the Potsdam Institute for Climate Impact Research (PIK) last Thursday, June 13th, to discuss climate change and climate policy with Director Ottmar Edenhofer and other researchers. A special focus of the meeting lay on options for an effective and fair CO2 pricing. Besides Mrs Merkel, Minister of State to the Federal Chancellor, Helge Braun, spokesman State Secretary Steffen Seibert and experts from the Chancellery also took part. A good two dozen researchers from all research departments at PIK were involved in the round table discussion taking place the Great Cupola of PIK's historic Michelson building and presented research results on climate risks and possible solutions for the climate crisis.

Climate protection and peace are two sides of the same coin: Berlin Climate and Security Conference

04/06/2019 –Climate change knows no borders, and climate crises can affect security, ranging from food security and displacement to an increasing number of natural disasters. Indeed, a destabilised Earth system can make peace harder to achieve and sustain, and may even be a contributing factor to new violent conflicts. This makes our climate a foreign policy issue. In cooperation with the Federal Foreign Office and the think tank adelphi, the Potsdam Institute for Climate Impact Research has initiated the Berlin Climate and Security Conference to provide a forum for this rising issue. The summit will gather support for the “Berlin Call for Action”, directed at every foreign policy institution to step up efforts to address one of the greatest global security and foreign policy challenges of the 21st century: Climate change.

German coal phase-out could be in vain without CO2-pricing

04/06/2019 - It cannot be taken for granted that Germany’s plan to phase out coal by 2038 will actually decrease CO2 emissions on the European level. On the contrary, the phase-out could even increase emissions due to a complicated new mechanism in the European Emissions Trading Scheme, a team of researchers shows in a new analysis. To make sure the coal phase-out really helps stabilise the climate, it must be combined with a minimum price for CO2 or the cancellation of existing emission certificates.

Dutch royal couple visits Telegrafenberg

05/22/2019 - King Willem-Alexander and Queen Máxima of the Netherlands visited the Albert Einstein Science Park on Potsdam's Telegrafenberg during their stay in the State of Brandenburg today.

Petersberg Climate Dialogue: Johan Rockström addresses global leaders on climate action

14.05.2019 - "Science is clear: If we want to stabilize our climate, we need a fundamental change in all sectors of society. Because the bar is high: We need to halve our emissions every decade from now on. Only in this way can we attain zero net emissions by the middle of this century”, Johan Rockström, Director of the Potsdam Institute for Climate Impact Research, told international leaders on the occasion of the Petersberg Climate Dialogue. The two-day event is one of the most high-level events in terms of climate policy on the German and international political agenda, bringing together ministers and high-level representatives from 35 countries. The conference was co-hosted by the German Environment Minister, Svenja Schulze, and her Chilean counterpart, Carolina Schmidt, who is also President of the next UN Climate Change Conference in Santiago de Chile (COP 25).

Germany phases out coal to help stabilize our climate

27/01/2019 - The Coal Commission established by the German government recommends to phase out coal - with an end date in the 2030s. It is highly likely that political decision-makers will act upon this recommendation now and indeed put an end-date to coal-use in the world's fourth biggest economy Germany. The Coal Commission consisted of representatives from industry, trade unions, environmental associations, and academia. Experts from the Potsdam Institute for Climate Impact Research (PIK) were closely involved in the difficult negotiations. Physicist Hans Joachim Schellnhuber, PIK's Director Emeritus, was a member of the Commission. PIK's acting Director and chief economist Ottmar Edenhofer had been invited to provide advice to the committee.

Connecting the dots between risks and solutions: Policy design for the Anthropocene

10/01/2019 - From climate change to biodiversity, land-system changes or altered biogechemical cycles – to prevent the world from overstepping critical planetary boundaries and to tackle global, long-run, and interconnected environmental risks, a comprehensive policy framework is needed. An international team of researchers now combines insights of natural and social sciences in a perspective piece just published in Nature Sustainability, one of the outlets of the leading scientific journal. They analyze guiding principles for such a policy design to keep Earth within biophysical limits favorable to human life. Among the authors are Earth System researcher Johan Rockström and climate economist Ottmar Edenhofer, who form the new joint - and interdisciplinary - leadership of the Potsdam Institute for Climate Impact Research (PIK).

UN climate summit agrees on rulebook – yet more ambition is needed: PIK leaders at COP24 in „Heißzeit“ times

17.12.2018 - The Katowice UN climate summit’s results are “a relief” with regard to the agreed rulebook, according to the Directors of the Potsdam Institute for Climate Impact Research (PIK). However, the close to 200 states at COP24 failed to scale up ambitions for greenhouse gas emission reductions, say Johan Rockström and Ottmar Edenhofer. Concrete measures are urgently needed though since governments are steering Earth into a “Heißzeit”. This “hot age” has been investigated in scientific publications from PIK leaders, including Director Emeritus John Schellnhuber. The term “Heißzeit” has now been elected “word of the year 2018” in Germany.

Climate plan for Germany and Europe: Economists propose CO2 price reform

03.12.2018 - A few days ago the UN Environment Agency advocated an international green tax reform - now economists have presented a new concept for a CO2 price reform in Germany and Europe right before the start of the climate summit in Katowice, Poland. SPIEGEL magazine was reporting on this issue in advance this weekend. Christoph Schmidt, Chair of the German Council of Economic Experts from RWI Essen, Leibniz Institute for Economic Research, and Ottmar Edenhofer, Director of the Potsdam Institute for Climate Impact Research (PIK) and the Mercator Research Institute on Global Commons and Climate Change (MCC), have jointly drafted the cornerstones for a market-based way out of coal. Climate-damaging CO2-emissions would need to become more expensive, while at the same time the electricity tax could be lowered. A socially just and efficient transition to a sustainable economy is possible, according to the professors, who both belong to the Leibniz Association. If, on the other hand, greenhouse gas emissions were not reduced, there would be the risk of economic climate damage of unprecedented proportions.

Planetary Boundaries and Global Commons - managing risks and solutions

11.12.2018 - Weather extremes, food security, migration: people's livelihoods depend on climate stabilization. The joint side event of the Potsdam Institute for Climate Impact Research (PIK) and the Mercator Research Institute on Global Commons and Climate Change (MCC) at the UN climate summit COP24 highlighted how a safe operating space for humanity within Planetary Boundaries and the sustainable use of Global Commons like the atmosphere are key concepts combining natural and social sciences to safeguard our future. Based on these fundamental concepts, sound options for managing risks and solutions were explored by the new joint PIK leadership Johan Rockström and Ottmar Edenhofer.
