SPECIAL: Direct CO2 pricing gives room for additional voluntary emissions reductions

Foto: iStockMost climate economist agree that it makes sense to put a price tag on the emission of the most important greenhouse gas carbon dioxide, CO2. The discussion primarily revolves around whether it would be better to achieve this through a tax or emissions trading. Arguments include the administrative effort involved, the signal effect for investors, and the political enforceability. A new study based on a scientifically controlled experiment now sheds light on another aspect that has barely been researched so far: the incentive effect of both options on actors who want to act morally beyond their economic interests. The study was conducted by the economists Axel Ockenfels, Peter Werner and Ottmar Edenhofer, and has now been published in the renowned journal Nature Sustainability. Read more...

Engage with the altruists, ignore the free-riders: New study explores communication dynamics in climate negotiations

Engage with the altruists, ignore the free-riders: New study explores communication dynamics in climate negotiations

07/16/2020 - Communication is the key to overcoming the social dilemma of mitigating climate change, which requires investments from various actors towards a common goal. According to a new study published in Proceedings of the National Academy of Sciences (PNAS) and co-authored by Jürgen Kurths and Hans Joachim Schellnhuber from the Potsdam Institute for Climate Impact Research, communicating sentiment and outlook significantly improves group interactions in climate change mitigation processes.

An Economic Case for the UN Climate Targets: Early and strong climate action pays off

An Economic Case for the UN Climate Targets: Early and strong climate action pays off

13/07/2020 - Climate action is not cheap – but climate damages aren’t, either. So what level of climate action is best, economically speaking? This question has puzzled economists for decades, and in particular since the 2018 Nobel Prize in Economics went to William Nordhaus, who found 3.5 degrees of warming by 2100 might be an economically desirable outcome. An international team of scientists led by the Potsdam Institute has now updated the computer simulation model used to come to this conclusion with latest data and insights from both climate science and economics. They found that limiting global warming to below 2 degrees strikes an economically optimal balance between future climate damages and today’s climate mitigation costs. This would require a price of CO2 of more than 100 US Dollar per ton.

Road access for all would be costly, but not so much for the climate

Road access for all would be costly, but not so much for the climate

10/07/2020 - One of the UN’s Sustainable Development Goals aims to ensure access to transport infrastructure for all. A team of researchers led by the Potsdam Institute for Climate Impact Research (PIK) has now brought together various data sets to quantify the economic costs as well as climate implications of achieving this goal by providing universal road access. The result: While such road extension would weigh very heavily on individual countries’ budgets, on the global CO2 emissions budget it would not. To connect almost all the world’s population, the global road network would only need to be extended by 8 per cent, causing a total CO2 emissions of about 1.5 per cent of what we can emit while keeping global warming below 2 degree Celsius.

Science Platform Climate Protection: The German government's Corona economic stimulus package needs a climate impact assessment

Science Platform Climate Protection: The German government's Corona economic stimulus package needs a climate impact assessment

07/09/2020 - On July 9, 2020, the Steering Committee of the German Science Platform Climate Protection (WPKS) presented and discussed with State Secretaries Jochen Flasbarth (BMU) and Wolf-Dieter Lukas (BMBF) a statement on climate policy requirements for the design of economic stimulus packages in the Corona crisis. Eight renowned scientists from various disciplines coordinate the tasks of the Science Platform Climate Protection in the Steering Committee. In doing so, they support the Federal Government in the implementation and further development of the Climate Protection Plan 2050 and thus contribute to achieving national, European and international climate protection goals.

Innovations for sustainability in a post-pandemic future

Innovations for sustainability in a post-pandemic future

07/07/2020 - The COVID-19 pandemic has thrust the world into turmoil and disrupted the status quo, but it is also providing opportunities for innovation in the way we live and work. According to the latest report released by The World in 2050 (TWI2050) initiative, the crisis can lead to creating sustainable societies with higher levels of wellbeing for all. Beyond political will, small-scale, granular innovations that are affordable and can be widely applied are key here.

Shaping the energy transition together: Kopernikus project Ariadne launched

Shaping the energy transition together: Kopernikus project Ariadne launched

03/07/2020 - From our energy supply to the industry and the Paris climate targets, from individual sectors to the big picture: a network of leading research institutions is now starting an unparalleled research process focused on shaping the German energy transition. The Ariadne project aims at improving our understanding of the impact of different policy instruments in order to develop sound strategies for change. From the very beginning, a comprehensive dialogue between decision-makers from politics, business, and civil society will be a core part of the project.
