Energy & Climate Change practice

Supporting your journey to net zero

The biggest medium and long-term issue of our time is how to meet our energy needs in a way that sustains the future of the planet, while also sustaining the sector which is so essential to society. Our deep understanding of the Energy sector and its transition to decarbonisation, helps bring insight on climate change issues and transformation to clients across all sectors.

Holistic advice, unique insight

With over 450 lawyers, the CMS Energy and Climate Change practice is one of the world’s largest. We provide crucial advice to governments and businesses as they engage with the challenge of climate change and shape their responses to it. 

Since the 1980s we have led the way in designing and implementing modern energy markets around the world. We have also helped to guide the renewables sector at every stage of its development, from the earliest windfarms to solar PV, floating offshore wind, energy storage and electric vehicle infrastructure. 

Many of our clients require specialist legal advisers attuned to global geopolitics, economics and regulation. Our involvement goes far beyond straightforward power expertise, as we help them navigate increasingly interlinked issues such as technological disruption, electrification of transport, smart cities and urbanisation, social concerns and political agendas. 

We ensure that the jigsaw pieces of the overall energy and climate change puzzle are not looked at in isolation, whether we are advising on climate change strategy or new technology, oil & gas exploration or energy efficiency, project finance or M&A, energy disputes or regulation.
