Short answer: the best climate tech PR agency depends on your market. For a communications agency with a large climate and energy practice in the US and Europe, Antenna Group. For established B2B and cleantech companies wanting a long-term partner, Inkhouse. For deep tech climate storytelling, LaunchSquad. For New York climate tech and enterprise tech, Kite Hill PR.

Full disclosure: this guide is written by Joseph Tannous, founder of Jamco PR, which is one of the agencies below. We've tried to be fair about when each agency is the better choice, including when that isn't us.

Climate tech companies sell long, technical deals to utilities, industrial companies, governments and enterprises, often while raising large rounds or project finance. Buyers and investors have grown wary of greenwashing, so credible coverage, clear data and visible technical leaders matter more than bold claims.

Which agency fits your climate tech company?

Avoid greenwashing

Journalists, investors and regulators scrutinise climate claims. Back every impact number with a method, distinguish pilots from deployments, name customers only with approval, and let technical leaders explain how the technology works rather than relying on slogans.
