The environment is a hot topic, both literally and figuratively. It pertains to the most important and monumental challenge humanity has ever faced and as time goes forward there is even less room to address the issue.

The European Union and most of its Member States have been leading by example in setting ambitious targets. However, with the environment, there is always more that needs to be done, some angle that has been forgotten, or one actor that underdelivers on their commitments. The EU will have to grapple with these problems as they attempt to address the health crisis with a green recovery.

The EST Working Group on Environment will publish a series of policy briefs analysing different aspects of how the EU’s strategy addresses the environmental challenges ahead. Some topics assessed will include the decarbonisation of heavy industry; alternative fuel sources; renewable energies; sustainable agriculture, and other nuanced topics. Beyond these policy briefs, the Working Group will participate in discussions, panels and conferences related thematical environmental issues.
