Wilson Sonsini helps clients go on offense, seizing opportunities to anticipate and respond to climate-influenced customer demand, create and deploy new products, and improve the bottom line through thoughtful, bold, and impactful decarbonization strategies.
Wilson Sonsini is the law firm of choice for the undaunted and innovative companies, investors, and lenders launching ground-breaking products, services, transactions, and projects to address sustainability challenges and provide climate solutions.
We have advanced the new business models, future-forward technologies, and financing mechanisms that are revolutionizing how energy is generated, transmitted, sold, and consumed.
We represent leading investors—including venture capital and private equity firms, domestic and offshore strategics, and financial institutions—backing the development, commercialization, and mass deployment of new energy technologies. We also represent progressive institutional investors engaged in impact investing to address ESG goals and opportunities.
Climate change, resource scarcity, and environmental, social, and governance (ESG) requirements are reshuffling the deck of winners and losers in the global business world. Most law firms advise businesses to play defense: to compartmentalize risk, delay investment, and resist change. Wilson Sonsini partners with companies that embrace change as a once-in-a-lifetime opportunity and are determined to come out on top.
Whether rooftop solar, EV fleet charging, advanced battery technologies, green data centers, corporate energy efficiency and renewable energy procurement, renewable fuels, carbon capture and sequestration, or sustainable agriculture, we have joined our clients in the risk and reward of launching and growing innovative energy companies, structuring and negotiating first-of-their-kind energy transactions, helping clients seize opportunities in complex energy markets and regulatory schemes, and pioneering creative financing structures that streamed billions into projects and companies.
Our work in sustainability, climate, and decarbonization continues the firm’s legacy of representing technology pioneers and taking world-changing ideas from concept to implementation. We don’t just work with innovative companies—we are an innovate company, according to Fast Company’s prestigious annual list for 2022—the first time a law firm has ever received this distinction.
Over hundreds of seed rounds, private equity-backed company formations, strategic joint ventures, tax equity financings, IPOs, and long-term clean energy procurements, we have created a track record of success. Our investor-side clients know that we couple high-caliber transactional talent with deep, practical experience in the project, commercial, and regulatory areas critical to investment decisions. Fortune favors the bold, and the bold favor Wilson Sonsini.
Our team’s experience—and the novel, sophisticated approach we take in our work—is a key part of our brand. But it is the quality and quantity of innovative clients we work with that sets us apart from competitors and makes Wilson Sonsini a legal partner like no other.
From the dawn of semiconductors and software to today’s clean energy developments, Wilson Sonsini continues to work with the biggest name clients that are advancing climate and sustainability pursuits in markets worldwide. These companies, both large and small, are connecting formerly disconnected segments now engaged in launching sustainable products that contribute to energy efficiency and energy use reduction.
In addition to the climate solution providers, Wilson Sonsini helps companies execute on strategies to lower their carbon footprint and meet sustainability goals. From renewable energy and carbon offset procurement to implementation of carbon sequestration technologies in industrial processes, we have unique expertise to get the deals done necessary to meet climate and sustainability goals.
