The U.S. renewable natural gas (RNG) industry is growing fast, with 78 projects up and running in North America (72 in the U.S.) and 54 more in the works across the U.S. The RNG Coalition, a trade association supporting the development and deployment of these projects, is pushing to see that number double by 2025.

If the growth trajectory happens, it could mitigate methane while bringing business opportunities to landfills, which produce most of the RNG sold in North America.
