The Summit will focus on the ambitions, targets and needs of cities driven by climate commitments towards net-zero action. But our discussion will be far from abstract: participants will be also equipped with a newly launched, open CADS Tool designed to support cities in making climate-informed decisions!

With passionate climate leaders from the Baltic Sea Region, we will explore:

• what effective climate decision-making looks like in practice,
• what has already been achieved through applying EU climate strategies on the ground, and
• how can climate budgeting be applied in communicating climate goals and needs to your Mayor and Citizens.

We meet in Brussels!
