The 26th UN Climate Change Conference of the Parties − COP26 – is happening at the moment, with countries to be asked to cut emissions by 2030 in keeping with the goal of striking net zero by the middle of the century. The European Union (EU) aims to be climate neutral by 2050, as climate change and environmental degradation loom large over its economies and societies, including the Visegrad countries (V4). The summer heat wave in Europe, with its increased risk of wildfires and impact on food prices coincided with flash floods cause chaos in many countries while Poland and Czech Republic suffered devastating tornadoes. These extremes flag risks for the future. Diana Süsser and her colleagues from the V4SDG Lab organised an online workshop on climate action in the Visegrad countries and summarised the debates in this blog post.
