Transport Decarbonisation

CMS has market-leading experience in transport decarbonisation. We offer a full-service, cross practice approach that brings together our sector specialists, who understand the technical and commercial considerations posed by this fundamental shift towards electrification and low-carbon alternative fuel technologies such as hydrogen, biomethane and synthetic fuels.

Our team advises on the full range of sector needs, including: policy and regulation; M&A and joint ventures; fundraising and financing; competition and anti-trust; manufacturing and procurement; product liability; energy supply, grid flexibility and connection arrangements; real estate; consumer protection; technology development and IP protection; data privacy and cyber security; and tax.

We provide integrated, end to end support as clients scale, including the development of legal, compliance and governance processes, contractual templates, and robust processes and tools.

Our global network of offices in 50 countries allows us to support clients operating internationally with seamless cross-border advice. With more than 800 lawyers, including over 200 partners, the CMS Energy and Climate Change practice is one of the largest of its kind in the world.
