Carbon Capture, Sequestration, and Mitigation

Nixon Peabody’s Carbon Capture, Sequestration, and Mitigation team works with clients to develop and finance projects, infrastructure, and technology designed to reduce carbon emissions, including through the advancement of low carbon fuels, including blue hydrogen, renewable fuels and biofuels, equipment retrofits and carbon capture, utilization, and sequestration (CCUS).

Our Approach

We help our clients navigate and benefit from federal tax credit regimes, such as IRC Section 45Q, voluntary carbon credit programs, federal renewable fuel programs, U.S. Department of Energy and U.S. Department of Agriculture financing opportunities and state level initiatives, such as California’s Low Carbon Fuel Standard (LCFS). Our clients include, project developers, public power, industrials, private equity funds, tax equity investors, issuers, underwriters, and lenders.

As an early thought-leader in the CCS space, Nixon has actively participated in the dialogue relating to IRC 45Q and related IRS guidance and regulations, OCC bank regulations relating to tax credit financing, and proposed low carbon legislative initiatives. Our attorneys foster cross-industry discussions and education designed to accelerate investment in, and the transition to, CCS and other carbon mitigation technologies and projects. As the Biden administration moves to reset the national climate agenda, Nixon attorneys will be tracking these developments and will advise our clients of new opportunities, required operational changes to their businesses, and shifts in corporate ESG and climate-related disclosure.
