Energy & Climate Change lawyers

The energy and climate change sector, a key driver of the global economy, is affected by and affects global geopolitics, economics and regulation. You require advisors who not only understand your industry but also work on cutting edge issues with leaders of energy companies, regulators, governments, industry bodies and investors.

Our team works globally within every part of the energy sector, including upstream and downstream oil and gas, electricity in all its forms, including generation, networks, wholesale and retail markets, and nuclear and renewables, including solar and other green energy and clean tech. Over the last 25 years, our experts have helped shape the sector by creating the legal frameworks upon which many of your markets are based.

Whether you are a NOC, IOC, independent, electricity company, investor, government or financial institution, or contractor, we have the energy and climate change specialists to meet all your strategic challenges globally. Our multi-disciplinary team has helped shape the legal framework for the oil and gas industry in many jurisdictions and was among the first to advise on industry-shaping reforms such as the historic energy and climate change sector restructuring in Mexico. We also work on M&A, projects and financings in the oil and gas, power and renewables sectors across the globe. This collective experience means we can pre-empt and provide answers to the commercial, risk and regulatory issues you face in the energy sector.
