International law firm Bird & Bird has once again been recognised as the Most Active Legal Adviser in both Clean Energy Project Financing and M&A, and named one of the Most Influential Law Firms in Renewable Energy in the 2025/2026 edition of the Clean Energy Legal Advisers Report, published by Clean Energy Pipeline. The firm ranked first by deal volume in both categories, reaffirming its position as legal advisers at the forefront of the global energy transition.
Leading by deal volume across project financing and M&A
Bird & Bird was recognised as the most active firm in clean energy project financing by deal volume and, for the ninth consecutive year, was named the most active adviser in clean energy M&A by deal volume. Clean Energy Pipeline’s ranking system assesses the work of legal advisers on project finance and M&A transactions across the renewable energy sector globally, spanning Europe, the Americas, the Middle East and Africa, and Asia Pacific.
Matthias Lang, Head of Bird & Bird’s international Energy & Utilities sector group, comments: “I am delighted to see Bird & Bird recognised as the most active legal adviser in clean energy — particularly as this is the ninth consecutive year we have topped the M&A rankings by deal volume. This is testament to the exceptional global Energy & Utilities team we have at Bird & Bird and we look forward to continuing to support our clients as the energy transition continues.”
Matt Bonass, co-Head of Bird & Bird’s international Corporate group, says: “Really exciting to see that our corporate energy team has once again been recognised as the most active firm globally in renewable M&A. Clean energy remains a core focus for the corporate and wider Bird & Bird team and this recognition is testament to the strength and breadth of our international team.”
Pierpaolo Mastromarini, Project Financing partner at Bird & Bird, adds: “Securing top spot in the project finance deals by volume rankings is a fantastic milestone, especially as we navigate an era of ‘first-of-a-kind’ structures and rapid technological integration. Financing complex projects in such a demanding regulatory environment requires more than just legal expertise; it requires a truly integrated and cohesive cross-border team.
“Our success reflects a deep partnership with increasingly sophisticated clients and a diverse array of lenders, from traditional banks to private credit funds, in a market that is rapidly opening up to new credit providers. We pride ourselves on a collaborative workplace that bridges jurisdictions seamlessly, allowing us to deliver the innovative, multi-layered debt solutions required to drive the future of global infrastructure and energy.”
