About CMS

Select your region

With more than 450 energy and climate change lawyers, including over 100 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 75+ 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.

A key driver of the global economy, the energy and climate change sector is affected by geopolitical, economic and regulatory pressures. You require advisors who understand your industry and work with leaders of energy companies, regulators, governments, industry bodies and investors on the cutting edge of commercial, regulatory and risk issues in the sector.

Based in 15 jurisdictions in Central and Eastern Europe, we have been active in CEE since the beginning of the privatisation and liberalisation of the energy and climate change sector in the region. We have helped to shape the sector by advising on the most high-profile and ground-breaking projects and transactions over many years.

Our dedicated energy and climate change lawyers work in every part of the sector, including upstream and downstream oil & gas, electricity, nuclear and renewables. Whether you are a NOC, IOC, independent, electricity company, investor, government or financial institution, we have the energy and climate change specialists to meet all your strategic challenges globally.

Our multi-disciplinary teams were among the first to advise on ground-breaking global oil and gas M&A and on power projects in Europe, to establish a single electricity market in Northern Ireland and the Republic of Ireland, lead historic electricity industry reform in Mexico, and work on renewable energy projects globally.

The Energy & Climate Change Team in Hungary is one of the most significant market players with a strong market share in renewable energy and oil & gas. Moreover, the uniquely broad expertise of the team members covers every segment of the energy market with a focus on electricity, oil & gas, and chemical and environmental related matters.
