Renewable Thermal Certificates (RTCs) allow you to directly and immediately address natural gas emissions

There has been a growing demand for an accessible tool for mitigating emissions from using natural gas. Enter RTCs. 

RTCs also called Renewable Natural Gas (RNG) Certificates or Green Gas Certificates in Europe, offer a fossil-free alternative for powering your business. Matching RTCs to natural gas consumption can reduce or address natural gas emissions under many compliance and voluntary standards. 

Learn how your company can help lead the RNG movement.

What is Biogas?

Biogas is methane generated from:

  • Decomposition of wet organic waste. Anaerobic digesters at food processing plants, livestock facilities, and wastewater treament plants.
  • Gas collection systems and landfills
What is Renewable Natural Gas?

Renewable Natural Gas (RNG) is cleaned or “upgraded” biogas that has been injected into the national pipeline system. RNG is a climte-friendly alternative to fossil/geologic natural gas.

Synonyms: Biomethane, high BTU biogas.

What are Renewable Thermal Certificates?

Renewable Thermal Certificates (RTCs) are the environmental attributes associated with RNG.

Synonyms: Thermal RECs, Green Gas Certificates, Renewable Gas Guarantee of Origin (RGGO), RNG Certificates.

Renewable Natural Gas

Though Greenhouse Gas Protocol has yet to finalize guidance on RTC usage, leading voluntary standards such as The Climate Registry and RE100, allow entities that purchase RTCs the ability to claim the environmental benefit of substituting RNG for conventional natural gas.

Renewable Thermal Certificates benefits

Provides a claim to consuming renewable natural gas and the associated emissions profile under programs run by the California Air Resources Board, Environmental Protection Agency, The Climate Registry, RE100, and others.

Streamlines attribute purchase without changing the current natural gas supply, through RTCs and one nationwide interconnected pipeline network

Allows the ability to access lucrative Clean Fuel Standards credits when gas is used as transportation fuel

Reduces the carbon intensity of the national fuel mix and displaces fossil gas
