We are a boutique law firm that specialises in international and European climate law and policy.

We are climate law nerds in the true sense of the word, with a keen understanding of how climate risks affect all aspects of today's society, markets and enterprises. And we are here to assist you on your journey towards your climate goals.


Our founding partner, Cathrine Ramstad Wenger, has more than ten years experience from public and private sector working with climate law and renewable energy law since she graduated with an LLM in international environmental law from UCL in London.
