For years, wastewater treatment plants quietly did their job behind the scenes—protecting public health by cleaning our water and keeping communities running smoothly. Today, those same facilities are stepping into an exciting new role. Thanks to advances in...

Sustainable Aviation Fuel (SAF) and the RFS: Are We Ready for Takeoff?

by Brianna Welsh | Dec 1, 2025 | Renewable Energy

Aviation is often considered one of the hardest industries to decarbonize. While cars and trucks can transition to electric power, aircraft still rely on extremely energy-dense liquid fuels to stay aloft. Sustainable Aviation Fuel (SAF), a low-carbon alternative to...

How Dairy Farms Are Cashing in on the Renewable Fuel Standard

by Brianna Welsh | Aug 21, 2025 | Renewable Energy

Dairy farming has always faced the challenge of managing manure, a byproduct rich in nitrogen and methane. Now, thanks to technology and the U.S. Renewable Fuel Standard (RFS), that challenge is becoming an opportunity. Through anaerobic digestion, farms are...

Turning Waste Into Fuel: How Landfills and Digesters Drive RNG and RIN Generation

by Brianna Welsh | Aug 7, 2025 | Renewable Energy

What used to be seen as messy environmental problems—like landfills, farms, and wastewater treatment plants—are now getting a second chance. These places are becoming powerful players in the clean energy space, thanks to Renewable Natural Gas (RNG). By capturing...

Unlocking Carbon Intensity: How the GREET Model Empowers Renewable Fuel Producers

by Brianna Welsh | Jul 10, 2025 | Renewable Energy

A key aspect of the RFS program and its related incentives is the concept of “Carbon Intensity” or CI. CI measures the Lifecycle Greenhouse Gas (GHG) emissions per unit of energy produced. For renewable fuel producers, or any other obligated party, understanding and...

How Methane-Tracking Satellites Are Shaping the Future of RFS and RNG Compliance

by Brianna Welsh | Jun 19, 2025 | Renewable Energy, Uncategorized

In March 2024, the Environmental Defense Fund (EDF) launched MethaneSAT, a groundbreaking satellite designed to track and reduce methane emissions from oil and gas operations. Just a few months later, in August 2024, NASA’s Jet Propulsion Laboratory introduced its own...
