Environmental, Social, and Governance


Emissions from our operations vary by business segment. Our air emissions generally result from mining activities, crude oil storage tanks, combustion sources, and crude oil and natural gas transportation. With the exception of our soda ash mining operations in Green River, Wyoming, and our Garden Banks-72 offshore platform, all of our facilities are classified as minor sources of air emissions under the Clean Air Act. Our air permitting and compliance program manages applicable regulated emissions using the various methods mentioned below:

  • Maintaining a robust permitting and compliance program for operational activities
  • Tracking permit requirements and deadlines in a compliance tracking system
  • Calculating annual emissions as required by federal and state regulations
  • Reviewing plans for modifications to facilities and operations to determine whether permitting is required
  • Using control technology when feasible to reduce emissions
  • Operating all of our marine vessel engines and generators to meet Tier 3 standards, using low sulfur diesel, which meets IMO 2020 standards
  • Phasing out Ozone Depleting Substances from marine vessel A/C units

We continually look for additional efficiencies in our operations and new ways to reduce our air emissions. Recently, Genesis Energy opened our new Sodium Hydrosulfide Terminal in Lake Charles, Louisiana. The location of this new terminal is only 8 miles away from our Sodium Hydrosulfide plant in Westlake, Louisiana, which reduces the number of miles driven by tractor trailers carrying product between points of transfer by approximately 266 miles (94 percent) round trip. By decreasing the amount of time the tractor trailers carrying hazardous materials are on the road, we not only reduce our transportation costs, but also dramatically reduce our vehicle emissions and risk of accidents.

Greenhouse Gas Emissions

Scope 1 and 2 emissions for our operations are shown in the table below. Calculations were performed in accordance with the U.S. Environmental Protection Agency Greenhouse Gas Reporting Protocol. We intend to continue to track and analyze this data in the future.

1 Reductions shown in 2020 are partially due to impacts from the COVID-19 pandemic and business interruptions from an active hurricane season.

2 Emissions data for certain offshore platforms where regulatory reporting of such data is not required is excluded.  We began collecting the emissions data in 2021.

3 Methane emissions are included in the total Scope 1 and 2 emissions.

4 Data excludes office spaces and facilities where electricity is not metered separately from other building tenants or is charged as part of a lease.

The data appearing above is an approximation and is expected to fluctuate and change year over year. It should not be interpreted as being indicative of trends or guarantees of future results. Genesis Energy expressly disclaims, any representation or warranty as to the accuracy or completeness of such data. The data may be modified, updated, changed, deleted or supplemented from time to time without notice.

Climate Change

We recognize that climate change is an important topic for our investors.  We continue to look for ways to position ourselves to operate and participate in a lower carbon world.

We expect our soda ash business to increase its participation in renewable energy markets in the future by producing a resource used in the production of LEED certified glass windows to retro-fit older buildings; manufacturing of glass for solar panels; and the production of lithium carbonate and lithium hydroxide (some of the building blocks of lithium ion/phosphate batteries used in both the electrification of vehicles and long-term battery storage).

Our refinery service business continues to help its host refineries lower their emissions by processing hydrogen sulfide gas stream using our proprietary, closed-loop, non-combustion technology to remove sulfur from refiner’s hydrogen sulfide gas stream.  In addition, sodium hydrosulfide (NaHS) is used by our customers to help further reduce air emissions from various chemical and industrial activities. For example, NaHS is used to remove nitrogen oxide (NOx) from the emissions stacks of certain activities around metal refining and finishing.

NaHS and soda ash are also both used in flue gas scrubbing to remove harmful particulates from what would have otherwise been released into the atmosphere. This is often used at large industrial complexes and hydrocarbon-fired power plants.

We also recognize stakeholders’ desire for more disclosure on climate-related risk assessment and management and are considering integrating recommendations from the Task Force on Climate-related Financial Disclosures in the future.
