Certified natural gas is ‘dangerous greenwashing scheme’, US senators say

Group of progressive senators led by Ed Markey call for crackdown on certified natural gas in letter to US federal regulators

Certified natural gas - or methane gas that is purportedly produced in a low-emissions manner - is a dangerous greenwashing scheme", a group of progressive senators wrote in a letter to federal regulators on Monday.

The letter, addressed to Federal Trade Commission chair, Lina Khan, comes as the agency prepares to release its updated Green Guides, which clarify when companies' marketing claims around sustainability violate federal laws barring consumer deception, giving regulators stronger legal cases against polluters. Those guidelines should crack down" on claims made by gas certification programs, the lawmakers, led by Massachusetts's Ed Markey, wrote.
