Energy & Climate Change


A key driver of the global economy, the energy sector is affected by pricing, 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.

As an oil & gas company or an oil & gas services company, CMS can advise you as the leading firm in the sector. CMS has an internationally integrated practice providing services to energy companies operating around the world. We have helped to shape the sector by advising on some of the most high-profile and ground-breaking projects and transactions over many years. CMS Oman offers particular expertise on oil, gas, petrochemicals, power and water (including renewable energy) projects and transactions.

Our dedicated energy 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 specialists to meet all your global strategic challenges. Our multi-disciplinary teams were among the first to advise on ground-breaking global regional oil and gas M&A and on power and renewable projects in the Middle East, including one of the first renewable energy projects in the UAE.
