04/26/2018 - Together, 16 banks, the United Nations, business consultants and scientists produced first guidance to help the financial industry become more transparent on climate-related risks and opportunities. The report they jointly published, entitled “Extending our horizons”, is based on economic scenarios provided by the Potsdam Instititute for Climate Impact Research, the International Institute for Applied Systems Analysis, and the International Energy Agency. The innovative methodology will support banks to implement the ground-breaking recommendations of the Financial Stability Board’s Task Force on Climate-related Financial Disclosures (FSB TCFD). It focuses on changes that the transition to a low-carbon economy will present to businesses. A complementary report on the physical impacts of climate change for businesses is planned for release in late June.

29/03/2018 - The designated Director and chief economist of the Potsdam Institute for Climate Impact Research, Ottmar Edenhofer, accompanied the new Federal Foreign Minister Heiko Maas on his first visit to the United Nations in New York. Edenhofer was the only guest of the ministerial delegation. Germany seeks a non-permanent seat on the UN Security Council in 2019 and 2020. Minister Maas held a number of talks and campaigned for strengthening the United Nations in times of national unilateralist leanings.

03/29/2018 - Rapid greenhouse-gas emissions reductions are needed if governments want to keep in check both the costs of the transition towards climate stabilization and the amount of removing already emitted CO2 from the atmosphere. To this end, emissions in 2030 would need to be at least 20 percent below what countries have pledged under the Paris climate agreement, a new study finds – an insight that is directly relevant for the global stock-take scheduled for the UN climate summit in Poland later this year. Removing CO2 from the atmosphere through technical methods including carbon capture and underground storage (CCS) or increased use of plants to suck up CO2 comes with a number of risks and uncertainties, and hence the interest of limiting them.

02/26/2018 - Even countries that tend to act in an egoistic way in the long run have an incentive to participate in international climate stabilization pathways and couple CO2 pricing systems, a new game-theoretical study shows. Yet they might only do this if pioneer coalitions for pricing greenhouse gas emissions make the first steps. If this is the case, the egoistic countries temporarily enjoy the benefits of avoided climate change without paying for it, but in the longer term can join the pioneers and link to their already established models of CO2 pricing. Forming larger and larger coalitions always reaps additional benefits of avoided damages from climate change. These benefits, even though unequally distributed across the coalition members, can be distributed via financial transfers. This makes it attractive to join, even for egoistic countries.

14/02/2018 - The Potsdam Institute for Climate Impact Research (PIK) is the world’s most influential environmental think tank, a new ranking shows. For the ninth year in a row, PIK has been ranked among the top think tanks in the world working on environmental policy. The "Global Go To Think Tank Index Report 2017" that has just been published by the University of Pennsylvania, altogether considered more than 6,500 institutions across the globe.

02/07/2018 - While less new coal-fired power plants are now being built in China and India, the planned expansion in the use of coal in fast-growing emerging economies, such as Turkey, Indonesia and Vietnam, will in part cancel out the reduction. Only if the countries of the world actively counteract this trend, they can achieve the climate goals agreed in the Paris Agreement. These are the results of the study “Reports of coal’s terminal decline may be exaggerated,” authored by researchers from the Potsdam Institute on Climate Impact Research (PIK) and the Mercator Research Institute on Global Commons and Climate Change (MCC), published in the journal Environmental Research Letters

01/22/2018 - Planting trees or grasses on a grand scale in plantations to extract CO2 from the atmosphere - this could make a long-term contribution to climate protection, but it would push the planet beyond ecological limits in other dimensions. A new study by the Potsdam Institute for Climate Impact Research (PIK) in the journal Nature Climate Change now for the first time establishes a connection between ambitious international climate objectives and the more comprehensive concept of planetary boundaries. If biomass plantations in which plants bind carbon dioxide during growth are massively expanded, this would entail enormous risks for areas that are already stressed, such as biodiversity, biogeochemical flows, water resources and land use. According to the study, biomass as a means to capture and store CO2 can therefore only make a limited contribution. In order to stabilize the climate, a rapid reduction of greenhouse gas emissions from the combustion of coal, oil and gas is crucial.
