I think it would be more precise to say they are influenced by consumer demand. Consumers consume from landfills, dairy farms, and natural gas facilities, but they do not control them.

It is true that as a consumer, I can try to regulate my demand to reflect how I feel about those facilities' emissions.

At the time time, saying that consumers control those facilities seems to imply that the owners and operators bear no responsiblity for their emissions and are not empowered to change them.
