Louisiana
Louisiana generates more industrial emissions than any state except neighboring Texas. Three sectors are responsible for the bulk of emissions: petroleum and natural gas systems, non-fluorinated chemicals, and refineries. The state’s sixteen refineries, which refine approximately one-sixth of the nation’s oil, account for nearly 25 percent of industrial emissions. Petrochemicals, ammonia, and hydrogen account for most chemical production. Chemical production is concentrated in the corridor between New Orleans and Baton Rouge. Oil and gas extraction takes place both offshore and onshore.
- This map shows the top 20 emitters, coded by industrial sector. The size of the circles corresponds to emissions: the larger the circle, the higher the emissions.
- Disadvantaged communities (as determined by the federal government) are shaded blue.
- The inner circle provides a visual representation of the share of emissions generated by each industrial sector.
- The outer circle also indicates the share of a sector’s emissions generated in disadvantaged communities.
Climate pollution reduction grants
In 2024, the Environmental Protection Agency selected the City of New Orleans as a recipient of the Climate Pollution Reduction Grants. The anticipated award amount of $49.9 million will support the city of New Orleans in reducing greenhouse gas emissions across multiple sectors, including proposed projects in the industrial sector.
Examples of recently enacted legislation
Louisiana has enacted a range of legislation related to carbon capture and sequestration (CCS). In 2024, the U.S. Environmental Protection Agency (EPA) granted Louisiana primary enforcement authority (or “primacy”) over Class VI underground injection wells, which are used to permanently store captured carbon dioxide deep underground. This made Louisiana one of three states with primacy. Below is a high-level overview of carbon management bills enacted in the state between 2023 and 2024.
In 2023:
- HB 229 and SR 123 asked the United States Environmental Protection Agency to expeditiously grant the state of Louisiana’s application for Class VI primacy.
- SR 179 established the Task Force on Local Impacts of Carbon Capture and Sequestration to study the benefits and revenue streams of carbon capture and sequestration projects.
- HB 571 provides for additional notification to parishes about permitting and drilling Class VI wells for geologic storage, includes a tax on extracted CO2, modifies existing statutes on long-term stewardship, and directs additional revenue from carbon management projects to parishes.
In 2024:
- HB 937 clarifies landowner liability for CO2 sequestration.
- HB 169 clarifies responsibility for liability and damages resulting from CO2 sequestration.
- HB 516 includes additional regulations related to CO2 sequestration.
- HB 492 updates and clarifies existing laws related to eminent domain.
- HB 966 details the commissioner’s authority to order unitization, pooling, and consolidation of reservoirs for the geologic storage of CO2.
- HCR 64 created a Clean Hydrogen Task Force in Louisiana to study and make recommendations on the growing clean hydrogen industry, including its production, connective and storage infrastructure, and end-use.
