17 specialist practice areas in Energy & Climate Change

With more than 800 energy and climate change lawyers, including over 200 partners, the CMS Energy and Climate Change practice is one of the largest of its kind in the world. Led from its centres of excellence such as London and Aberdeen, the practice works across over 80 offices globally.

Our early work in designing and implementing modern energy markets and subsequently guiding the sector in the push to decarbonisation means CMS is not only a transactional or project adviser to the sector, but uniquely placed to help shape its present and future. 

The modern energy sector requires specialist legal advisers attuned to global geopolitics, economics and regulation. But as the sector has matured, rather than become more standardised and commoditised, the pace of change is accelerating. When the energy sector found itself on the frontline of decarbonisation, CMS guided the sector through this new landscape. CMS teams now work in every corner of the sector across the globe to help it meet the demands of climate change, technological disruption, urbanisation in developing economies, social concerns and political agendas.  

We have supported the success of our clients by recognising the sector is ever more diverse and by working actively against ‘silo thinking’. We are market-leading, global advisers on oil & gas exploration and production, mid-stream activities, traditional or newer electricity generation technologies, energy transition and climate change strategies, energy efficiency, finance, M&A, disputes or regulatory and commercial issues. Thanks to our cross-sectoral knowledge and expertise, we make sure clients receive the advice best suited to their commercial needs and to our collective future.
