who we are
Founded in 1994 and based in Brussels, Milieu Law & Policy Consulting is a leading firm in European Union (EU) and international law and policy.
We work closely with the EU institutions and other clients to provide high-quality legal and policy support throughout the policymaking cycle.
what we do
We support evidence-based policymaking by combining legal, policy, economic and technical expertise. Our services include:
Evaluations and fitness checks
Evaluations and fitness checks are central to the EU’s commitment to evidence-based policymaking as set out in the Better Regulation Guidelines and the Commission’s “evaluate first” principle.
Studies on implementation and enforcement
‘We believe that ‘law without enforcement is just good advice’ (Abraham Lincoln). Effective implementation and enforcement are essential to ensure that legislation achieves its objectives.
