I'm going to attempt to explain a type of egregious #Greenwshing you may never have heard about.

Geopolymers as low carbon cement.

Cement can be partly substituted, in a blend by waste from the coal or steel industries. These wastes have no CO2, and make cement stronger.

But they need the cement in the blend to produce strength (in particular early age strength)

"Environmental groups are suing Dutch airline KLM, alleging that adverts promoting the company's sustainability initiative are misleading."

"They argue that KLM adverts and their carbon-offsetting scheme create the false impression that its flights won't make climate change worse."
