The EU has committed itself to being climate neutral by 2050. This goal is important, ambitious and, to put it mildly, so dispersed that it is hard to make heads or tails of it. The EU project, MERLIN, with a budget of just over EUR 22 million, will play an active role in the green transition in Europe. It will calculate the benefits of initiatives and bring together experience and relevant stakeholders for future initiatives, thus ensuring that focus is on initiatives that can actually make an impact.
