 Clean technology can partially make up for weak CO2 pricing

Clean technology can partially make up for weak CO2 pricing

02/02/2015 - Clean technology support can to some extent make up for weak CO2 pricing and hence help keep the two degrees target within reach, a new study shows. Even if the world climate summit in Paris later this year is successful in striking a climate deal, it might not bring about sharp greenhouse-gas cuts in the near-term. However, emission targets could be strengthened by complementary policies, such as support for renewables, a ban on new coal-fired power plants, and an initially modest global minimum price on CO2. If such a policy package – each component of which has already been enacted in some countries – were to be put into practice globally now, this could also pave the way for a clean economy with faster long-term CO2 reductions after 2030.

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.
