Ten years after the January 2009 gas crisis, Russian-Ukrainian gas relations are at another turning point: the then concluded contracts are terminating on 31 December 2019. While trilateral talks brokered by the European Commission (EC) have started in July 2018, the real negotiations about the future of this relationship can be expected to start no earlier than in December, that is in the midst of the winter and a second to midnight. Crucial months lie ahead.

At a time when the European Union (EU) is discussing its long-term climate strategy and drafting new legislation to foster the decarbonization of its gas sector, a close look at the experience of Denmark, Germany and Italy with renewable gas production can provide valuable lessons. 

The Global Climate Action Summit held in September 2018 in California has highlighted the importance of cities for promoting clean energy solutions and for combatting climate change. While energy policies in most countries depend primarily on national governments, cities have the possibility to develop and implement innovative solutions and ambitious policies. Chinese cities should be at the core of these developments, as they are confronted with many energy and climate challenges, often at an unprecedented scale: notably air quality, traffic congestion, energy security and massive consumption of building materials. For instance, outdoor air pollution in China has reportedly caused 1 million premature deaths in 2016, and in 2014 only 8 out of 74 Chinese cities would meet the national standards in terms of air quality.
