Quantifying Emissions to Boost RNG Growth

Services Provided

Our client is a rapidly growing renewable natural gas (RNG) company with operations across North America. They partner with farmers to convert agricultural waste into a carbon-negative energy source enabling, to sustainable and profitable growth.

The Challenge - After a key departure, the new lead, with limited GHG knowledge, had to learn the operations quickly to provide the required data. 

Increasing pressure from the Board and investors meant our client needed help to quantify the avoided GHG emissions. Without an accurate baseline and expert guidance, they risked losing both trust and investment. They struggled with questions like:

  • How do we accurately track Scope 1, 2, and 3 emissions across multiple RNG facilities?
  • Which emissions factors apply to corporate travel, including private vs. commercial flights?
  • How do we calculate employee commute emissions across different regions?

    Faced with these uncertainties, they turned to YY to provide clarity and structure.

Solution

We began by running a GHG 101 Workshop for key staff and data providers, ensuring everyone understood the project’s scope and goals. From there, we designed an employee survey to gather employee commute data.  We also implemented a business travel emissions calculator to improve decision-making with travel.

Additionally, to capture the full picture, we assessed emissions across three main categories:

  1. Corporate – Offices, corporate travel, and employee-related emissions
  2. Operational – Emissions from running RNG plants, plus the downstream sale of RNG
  3. Development – Construction of new RNG facilities

After identifying all potential emission sources—utility bills, fuel usage, construction material lists, and travel itineraries—we applied recognized emissions factors from the GHG Protocol and U.S. EPA. This data enabled us to assemble the total company-wide footprint. 

Results

Over four months, YY worked closely with the client to gather and analyze the data. Our rigorous approach ensured the results would be audit-ready, providing confidence and transparency for shareholders and regulatory bodies alike. Key deliverables included:

  • Comprehensive Emissions Baseline: A full accounting of Scope 1 and 2, plus selected Scope 3 emissions across multiple sites and manufacturing plants in North America.
  • Emission Savings Assessment: An estimate of the emissions savings achieved using the client’s RNG compared to conventional natural gas.
  • Competitive Benchmarking: Presented industry-relevant metrics to show how the client stacks up against peers in the RNG space.
