Energy & Climate Change

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. 

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.

"The CMS team had shown commitment, dependability and dedication across the board on the deal."

Chambers, 2023

"From partners to trainees, they are all client-focused and knowledgeable."

Chambers, 2023

Chambers, 2023

"Their practical and commercial ability to apply comprehensive knowledge of regulations has proven invaluable."

Chambers, 2023

"The team is incredibly responsive to queries and they're always available to discuss issues. They always provide pragmatic, commercially astute advice."

Chambers, 2023

"An ability to quickly understand complex and technical industry issues and work seamlessly with other teams such as competition."

Legal 500, 2023

"They are always focused and take time to clearly explain the steps forward and risks involved."

Chambers, 2023

"Flexible approach to fees and making deals work. A strong partnership has been built over the last 10 years. They know energy and are quick to respond on potentially difficult issues. They are commercial rather than being purely legal. They set out the risks and then offer suggestions as to how to proceed."

Legal 500, 2023

"They are demonstrating rapid and impressive growth in which the quality of domestic and international work is conducted to an exceptional standard. I would suggest their practice matches and exceeds a number of their London competitors."

Legal 500, 2023

"CMS has a great network and goes the extra mile to develop relationships with clients. It is a go-to firm for oil and gas transactions."

Chambers, 2021

"Everything you would expect from an outfit like CMS, but with a little more charm than most."

Legal 500, 2023

“This practice is deeply embedded in the energy/oil and gas industry in the UK and in many countries overseas. It has an enviable strength in depth among its Energy partners and associates. It was the first City firm to open an office in Aberdeen, the UK’s oil and gas capital. My company has instructed this firm on UK and Asian projects and strongly recommend it. Very friendly partners and associates. A pleasure to work with.”

Legal 500, 2021

"Their subject matter expertise, can-do approach and proactivity is a major reason for our instructing CMS."

Chambers, 2021

“They do not waste time on unnecessary activity, but focus on the client request and execute it.”

Legal 500, 2021

“CMS are experts in oil and gas, they provide local advice but are also able to draw on particular specialist expertise from elsewhere in their organisation when required.”

Legal 500, 2021

"Depth and breadth of experience is top drawer – you will find they have been involved in most of the key deals in this sector."

Legal 500, 2022

"Excellent capabilities in the oil & gas sector, from project inception and development to the operational phase of a project to decommissioning."

Legal 500, 2022

"Leaders in energy transition and provide excellent technical and commercial support to new energy projects. Overall they offer the full package for 21st century energy and natural resources clients."

Legal 500, 2022

"Extremely client-oriented and results driven. They listen to what the client needs."

Legal 500, 2022

"Full service capability, deep industry knowledge and very pragmatic, solutions-focused advice."

Legal 500, 2022

Ten takeaways from COP27
COP27 fi­nally reached a con­clu­sion on Sunday morn­ing, when over­run­ning ne­go­ti­ations ended in a deal that de­lighted some sleep-de­prived del­eg­ates but bit­terly dis­ap­poin­ted oth­ers. Pro­gress was made on the is­sue of loss and dam­age, a fraught ques­tion for three dec­ades. But there was much less suc­cess in build­ing on the agree­ment reached at COP26 a year earli­er. In the words of UN sec­ret­ary-gen­er­al An­tónio Gu­terres, “our plan­et is still in the emer­gency room.”   Here are ten takeaways from two weeks in Sharm El-Sheikh.
