Mitigating climate change through fighting poverty

Mitigating climate change through fighting poverty

10/29/2014 - Progress in climate change mitigation hinges on the alleviation of poverty in developing countries. To this end, the international community should pursue a policy that prioritizes the global reduction of greenhouse gases just as much as the development objectives of poorer countries. This is the result of a study conducted by a team of scientists led by experts from the Mercator Research Institute on Global Commons and Climate Change (MCC) and the Potsdam Institute for Climate Impact Research (PIK).

New numbers, new movement: from the UN Climate Summit to the Global Carbon Project

New numbers, new movement: from the UN Climate Summit to the Global Carbon Project

09/25/2014 - The UN climate summit this week in New York brought progress in an unexpected way. "Most of the politicians in the hall gave speeches of the same old conventional type – effusive formulation, minimalistic commitment," said Hans Joachim Schellnhuber, Director of the Potsdam Institute for Climate Impact Research, who himself took part in the meeting of 120 heads of state. "But it took place against a novel background, generated on the streets of New York by more than 300,000 people. If the politicians don't pull from the front, civil society will just have to push. Last week we saw how climate protection is developing into a world citizens' movement."

The cost of delay: White House report citing PIK research

The cost of delay: White House report citing PIK research

08/30/2014 - Delaying climate policy might enhance costs substantially. The US government in a major recent report makes this finding a central message, citing a number of studies led by scientists of the Potsdam Institute for Climate Impact Research (PIK). Mitigation costs increase, on average, by approximately 40 percent for each decade of delay, the White House’s Council of Economic Advisors states in the report. Inaction is likely to cause persistent economic damages, they argue – many billions of Dollars each year in the US alone.

Reforming emissions trading: Failure is not an option

Reforming emissions trading: Failure is not an option

07/30/2014 - Courageous steps are required to reform the European Union Emissions Trading Scheme, argues Ottmar Edenhofer from the Potsdam Institute for Climate Impact Research (PIK) in a comment piece now published in Nature Climate Change. The centerpiece of the European climate policy is currently under great scrutiny, as permit prices have been too low to incentivize a switch to low- or zero-emission alternatives. While some ideas to correct this already move in the right direction, only a broad approach embedding for instance a price corridor could restore the main pillar of climate policy in the EU, argues Edenhofer.

IPCC Co-Chair calls for re-thinking of policy assessments

IPCC Co-Chair calls for re-thinking of policy assessments

07/04/2014 – When the Working Group III (WGIII) contribution to the IPCC’s Fifth Assessment Report, the most comprehensive assessment of climate change mitigation options to date, was accepted by IPCC member governments in April this year, governments could not agree on parts of its Summary for Policymakers during the approval process. As a result the material was cut. In the current edition of the journal Science, a Co-Chair and leading authors of Working Group III re-visit the approval session and comment on deleted content and the strengths and weaknesses of the IPCC process in a series of articles.

Emissions trading reform could result in billions of euros for European countries

Emissions trading reform could result in billions of euros for European countries

05/23/2014 - With a reform of the European Emissions Trading System (EU ETS), the economically troubled countries of southern Europe could increase their revenues by several billion euros per year while also increasing their competitiveness. This was the finding of an analysis conducted by the Mercator Research Institute on Global Commons and Climate Change (MCC) headed by Ottmar Edenhofer, chief-economist of the Potsdam Institute for Climate Impact Research. It was one of the issues debated at an international workshop in Berlin under the title "Closing the carbon price gap: public finance and climate policy", chaired by Edenhofer.

The European Emissions Trading System: options for reform

The European Emissions Trading System: options for reform

02/11/2014 - The most crucial instrument of European climate policy, the Emissions Trading System (ETS), is currently questioned to deliver the desired results as the sum to pay per ton of carbon is dwindling. To move beyond a narrow discussion of the adequate allowance price level, the association of European national academies of applied sciences Euro-CASE along with the Mercator Research Institute on Global Commons and Climate Change (MCC) is convening a high-level workshop in Brussels this week. It aims at exploring options for a reform, and to do so by embedding the discussion about the ETS in the context of its interaction with national policies as well as public finance.

Pathways to a new international climate regime: Scientists present options at COP 19 in Warsaw

Pathways to a new international climate regime: Scientists present options at COP 19 in Warsaw

10/31/2013 - How can the next global climate agreement combine bottom-up initiatives from the national or subnational levels with multilateral top-down coordination? And how can such “hybrid” approaches deliver ambitious mitigation? These questions are addressed in a joint Issue Brief now published by the Mercator Research Institute on Global Commons and Climate Change (MCC) – founded by Potsdam Institute for Climate Impact Research (PIK) and Stiftung Mercator last year – and the Harvard Project on Climate Agreements. The findings will be discussed on November 20 at a side-event at the UNFCCC Conference of the Parties, COP-19, in Warsaw, often referred to as the world climate summit.

Reaping the benefits of renewables in a nonoptimal world

Reaping the benefits of renewables in a nonoptimal world

07/02/2013 - Upscaling renewable energy technologies such as wind or solar has a number of direct effects – less greenhouse-gas emissions for instance, and lower local air pollution. Economists rightly recommend a well-tailored set of policy instruments such as emissions cap-and-trade for CO2 or SO2 to tackle these effects. However, in a world in which these instruments cannot be implemented effectively – that is reality in some parts of the world – cobenefits of climate policy like reduced local air pollution might be a compelling narrative. This can be actually observed in the US right now. Still, these are not a substitute for efficient policy instruments, argue Ottmar Edenhofer and his colleagues of the Potsdam Institute for Climate Impact Research in a comment to be published in the Proceedings of the National Academy of Sciences (PNAS) this week.

Risk management in climate impact research

Risk management in climate impact research

04/04/2013 - Even the best research cannot predict the future. To respond to the challenges of climate mitigation and adaptation, decisions have to be made based on uncertainties – for example when a new embankment is to be built that is supposed to withstand even a strong storm surge. Systematic strategies of risk management could enhance such decision processes and play an important part in the development of robust policy options, a team of international scientists, among them Ottmar Edenhofer from the Potsdam Institute for Climate Impact Research (PIK), writes in Nature Climate Change. Their study “Risk Management and Climate Change” analyses the use of appropriate instruments for the assessment of potential climate impacts.

„Green Growth“– Fairytale or Strategy? Climate Lecture 2012 at TU Berlin

12/03/2012 - Economic growth does not only lead to rising turnovers and incomes but also increases greenhouse-gas emissions. Can “Green Growth” be a way out of this dilemma? Is it “a fairytale or a strategy”? Right now, issues like this are being debated at the international climate summit in Doha. Two scientists explored solution paths at the Climate Lecture at Technische Universität Berlin this Monday in front of 1000 guests – British growth critic Professor Tim Jackson and the chief economist of the Potsdam Institute for Climate Impact Research and Professor at TU Berlin, Ottmar Edenhofer.
