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...

Federal Government reappoints Wolfgang Lucht to the German Advisory Council

10.06.2020 - The German government has reappointed Wolfgang Lucht to its German Advisory Council on the Environment. Lucht is co-head of the Earth System Analysis Department at the Potsdam Institute for Climate Impact Research and has been a member of the Council for the past four years. Only a few days ago, the seven-member Council submitted a report of several hundred pages - which is only published every four years - to the Federal Minister for the Environment, Svenja Schulze. The committee of professors repeatedly takes a critical stance on current issues and thus advises the government.

Making sense of climate scenarios: toolkit for decision-makers launched

Making sense of climate scenarios: toolkit for decision-makers launched

03/06/2020 - To make climate scenarios work for decision-makers, an international team of researchers developed a comprehensive interactive online platform. It is the first of its kind to provide the tools to use those scenarios – from climate impacts to mitigation and energy options – to a broader public beyond science. The scenarios help policy makers and businesses, finance actors and civil society alike to assess the threat of global warming and ways to limit it.

Corona crisis fuels hate against Chinese on Twitter: Commentary

Corona crisis fuels hate against Chinese on Twitter: Commentary

19/05/2020 - The COVID-19 pandemic has the world firmly in its grip with millions of confirmed cases worldwide and whole countries in full or partial lockdown. Despite calls for solidarity across borders and countless local support initiatives, various incidents prove that the corona outbreak has also given rise to a series of racist attacks against Chinese people and people with Asian looking features both on the streets and in social media networks. A team of researchers from the Potsdam Institute for Climate Impact Research has now investigated the use of discriminating language against Chinese people in the context of the COVID-19 pandemic on Twitter.

Caring for the future is key for cooperation to prevent climate collapse: study

Caring for the future is key for cooperation to prevent climate collapse: study

20/05/2020 - How much decision-makers care about the future and not just the present is one key factor for whether or not they take action to stabilize our climate. Another one is how severe they assume the impacts of climate collapse to be. However, the number of actors is decisive – for instance the number of relevant countries, since efforts to reduce greenhouse gas emissions have to be international to add up to the amount needed to prevent a crisis. This is shown by a novel mathematical study. It finds a strong effect of diffusion of responsibility in scenarios with large numbers of actors. The study combines game theory and learning dynamics to explore which options for enhanced political cooperation should now urgently be studied empirically.
