In March 2010, Dr. Camilla Bausch and Benjamin Görlach of Ecologic Institute hosted the 14th Climate Talk, together with Dr. Susanne Dröge of the German Institute for International and Security Affairs, where questions concerning the governance of the international climate finance were discussed.

At the third Climate Talk a first review of the allocation of CO 2 -emission-rights in Germany was conducted. Experts from business, science, and government discussed the practical and legal difficulties of allocation, both for industry and administration. Presentations were given by Dr. Simon Marr (Deutsche Emissionshandelsstelle - DEHSt), Dr. Jürgen Altenburg (RWE Power AG) and Peter Ebsen (Baker& McKenzie LLP).

In January 2008, the European Commission published ambitious targets with regard to the future share of biofuels in the transport sector. By 2020, 10% of the fuels used in transport shall be biofuels. Furthermore, in the climate policies of individual Member States, biofuels also play an important role. However, more and more critics argue against the use of bio-energy. Controversies emerge concerning the climate footprint of bio-energy and the effects of biomass use on biodiversity and food security. The Climate Talk convened experts who discussed potential strategies to address these problems.

The Linking Directive was the topic of the Climate Talk event which took place on 11 August. Experts from business, science, and government discussed the legal framework and the difficulties of putting JI (Joint Implementation) and CDM (Clean Development Mechanism) into practice within the framework of the European emissions trading scheme. Presentations were given by Dr. Patrick Graichen (Federal Government for the Environment - BMU), Thomas Langrock (German Agency for Emissions Trading - DEHSt) and Dr. Sascha Lafeld (3C).

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.

Climate change as a global phenomenon requires global action. The strategies of states are very multi-faceted and variable: next to the Kyoto Protocol (KP), which sets forth binding reduction targets, are a number of initiatives such as the Asian Pacific Partnership agreement for Clean Development and Climate (AP6) with a voluntary, technology-based approach, and the Action Program for climate protection put in place at the G8 Summit in Gleneagles. At the 9th climate talk it was debated whether these varied approaches are effective for climate protection, and to what extent they complement or compete and thus hinder one another.

"Waking the sleeping giant - Instruments for more energy efficiency in the EU" was the topic of the 19th Climate Talk, hosted by Dr. Camilla Bausch and Benjamin Görlach of Ecologic Institute and Dr. Susanne Dröge of the Stiftung Wissenschaft und Politik in June 2011.

The main cause of global climate change is the burning of fossil fuels, especially coal. The future climate policy will encounter major challenges from an expected substantial buildup of coal-fired power plants, resulting from the security of supply and production cost reasons. Some experts hope for a clean solution to this problem by turning to Carbon Capture and Storage (CCS). The Climate Talk on 24 May 2006 focused on the questions, of whether climate policy can reconcile itself with coal-fired energy production by using CCS and what kind of problems and challenges can be expected from this new technology.
