Tanner Johnson has over two decades of substantive experience at the intersection of local, state, and federal energy and environmental policy, with a focus on federal energy policy, economic development, environmental restoration, federal and NGO grant processes, and the purchase of land by federal agencies for conservation purposes. He works closely with former Senator Mary Landrieu to assist clients with economic and infrastructure development, federal advocacy, energy policy, disaster resiliency and adaptation, coastal and wetlands restoration, and other environmental and natural resources matters.

In recent years, Tanner has played a central role in advancing carbon management policy and projects in Louisiana. He represents a major carbon management company in securing one of the state's first Class VI Underground Injection Control (UIC) permits, and he assisted the State of Louisiana in securing primacy over Class VI permitting — positioning the state to directly regulate carbon sequestration projects while maintaining rigorous safety and environmental standards. He also founded and built Louisiana Citizens for Our Future, a statewide grassroots coalition promoting the safe, responsible deployment of carbon capture, utilization, and sequestration (CCUS) across Louisiana. The coalition engages directly with communities, educates policymakers, and advocates for policies that attract private investment, create well-paying jobs, and reduce emissions.

Prior to joining the firm, Tanner managed the $2.5 billion Gulf Environmental Benefit Fund — a grant fund resulting from the BP oil spill that supports coastal restoration in Louisiana — distributing over $1 billion to projects along the Louisiana and Texas coasts.

Outside of work, Tanner enjoys spending time with his wife Brooke and their two sons, Briggs and Bowen, and is an active member of his local community.
