The 17th Petersberg Climate Dialogue opened in Berlin, with UN Secretary General António Guterres calling for action on the global energy transition. This comes in response to rising prices due to the Iran war. Germany has hosted the dialogue since 2010 as a complement to the UN climate conferences. Around 400 participants are expected this year, including representatives from the business sector and Turkish Environment Minister Murat Kurum, who said multilateral cooperation has been weakened but not over. Guterre urged the participants not to let up on efforts to reduce greenhouse gas emissions and finance international action on climate change.
