Building a Strategic Approach to Natural Gas Sustainability

More businesses are looking to decarbonize their energy supply and implement sustainable operations and supply chains. With a strategic approach to natural gas procurement, you can build a customized plan to understand your operational footprint and achieve long-term sustainability goals.

Are you a large consumer of natural gas? If you burn natural gas in a boiler to heat a building or for process load, or as a transportation fuel in natural gas vehicles, renewable energy can be an important tool to reduce your carbon footprint. 

Carbon Offsets

  • A carbon offset is a verified reduction carbon dioxide emissions that can be used to offset Scope 1 or Scope 3 GHG emissions, which include emissions from on-site fuel consumption, company travel, or supply chain activities. 
  • With this solution, customers can offset their carbon emissions from natural gas consumption and other business activities by purchasing carbon offsets from Constellation. 
  • Although the use of carbon offsets is an indirect way to reduce GHG emissions and does not allow the customer to make renewable energy claims the way that a purchase of RNG does, carbon offsets provide a lower-cost option versus RNG to help customers achieve decarbonization goals. Carbon offsets can be separately recorded as an offset on sustainability reporting.

Program Benefits

  • Low cost alternative allowing businesses to offset emissions
  • Allows businesses to offset emissions made elsewhere beyond their own operations such as company travel and supply chains
  • No facility/equipment modifications required
  • Help fund projects that generate reduction in carbon emissions

Renewable Natural Gas (RNG)

  • RNG is pipeline-quality natural gas derived from the decomposition of organic matter, also known as biogas.
  • Raw biogas comes from various sources including landfills, wastewater treatment plants, and agricultural waste digesters.
  • A customer’s purchase of RNG attributes may also reduce the customer’s Scope 1 carbon emissions. Specific sustainability claims and emission reduction levels will depend upon how the customer is using natural gas and GHG emission reporting standards.

Once processed to remove impurities, the RNG is injected into the interstate pipeline to be used like standard natural gas. The environmental attributes associated with this RNG, which include reduced carbon emissions as compared to non-renewable natural gas, can be paired with a customer’s natural gas consumption to allow the customer to make renewal energy claims associated with natural gas use.

Program Benefits 

  • Renewable energy claims for natural gas end-use paired with RNG production
  • Achieve sustainability and decarbonization goals & reduce Scope 1 emissions
  • No facility/equipment modifications required
  • RNG can have economic benefits if paired with other end-uses of natural gas including RECs for power generation and transportation fuel.
