The debate regarding the expansion of nuclear energy capacity has gained new prominence in the face of climate change. In scientific and political scenarios, nuclear energy is often seen as an important element of a future energy system. Against this backdrop, the Climate Talk tried to evaluate the actual contribution of nuclear energy towards greenhouse gas reduction targets. Taking into account existing and emerging alternatives, the experts assessed the future role of nuclear energy in the international climate policy regime.

The first Climate Talk discussion revolved around "Climate Protection and Competition", as the contemporaneous debates between EU member states about the National Allocation Plans had raised many questions about climate protection measures and the distortion of competition. Presentations were given by Dr. Simon Marr (Deutsche Emissionshandelsstelle – DEHSt) and Steffen Hentrich (Rat von Sachverständigen für Umweltfragen – SRU).

The 22st Climate Talk on 25 June 2012 occupies itself with the question: which impetuses for international climate policy will expand out from the Rio+20 Conference? The debate at the event, organized by Ecologic Institute in cooperation with the German Institute for International and Security Affairs (SWP), was opened by Dr. Karsten Sach (BMU), Dr. Thomas Koenen (BDI), and Daniel Mittler (Greenpeace), who were all fresh back from Rio.

When designing emissions trading schemes, the decision on allocation methods is a crucial element. After a long and controversial debate, the German government has now decided to introduce the auctioning of credits. Approximately nine percent of all allowances will be given out against payment in the second trading period (2008–2012). In 2008, rules for the German auctioning system are expected to be specified by a regulation. Environmental economists tend to support auctioning for reasons of efficiency while many politicians and the public mostly expect the reduction of unwanted distributional effects (“wind-fall-profits”).

The 21st Climate Talk, which took place on 6 March 2012, addressed issues regarding fracking and was entitled "Shale gas and fracking - an energy revolution in Europe?"
 Shale gas - natural gas trapped deep in underground rock formations - has provided hope for an energy revolution in Europe. Because the gas can only be retrieved with the technique of "hydraulic fracturing" (short: "fracking"), which uses great quantities of water and sand as well as chemical components, the potential environmental effects are being discussed intensely and controversially.

"Limited Freedom above the Clouds: Aviation Becomes Part of European Emissions Trading Scheme" was the topic of the 20th Climate Talk, hosted by Dr. Camilla Bausch and Benjamin Görlach of the Ecologic Institute, as well as Dr. Susanne Dröge of the German Institute for International and Security Affairs (SWP) on 21 November 2011.

This article, written by Ruta Landgrebe and Benjamin Boteler from Ecologic Institute in the theme issue of the German League for Nature, Animal Protection and Environment’s (DNR) newsletter, concerns environmentally harmful EU subsidies in the agricultural and fisheries sectors and argues for continued support for the "greening" of the EU budget, including the elimination of environmentally harmful subsidies for the new seven-year funding period 2014-2020.

On 9-10 February 2012, DG Environment of the European Commission organized the 2nd Stakeholder Workshop for the Fitness Check of EU Freshwater Policy in Brussels. Lessons learned from this workshop contribute to the design and assessment of policy options for the Blueprint to Safeguard Europe's Water Resources. Eleftheria Kampa and Johanna von der Weppen contributed to the workshop conclusions. The conclusions are available for download.

Ecologic Institute compiled the national study for Germany, which focused on the Rhine and Elbe basins and mainly analyzed the origins and experiences of public participation approaches in water management. The study is available for download.
