Generally consumers, and I agree with your overall sentiment, but other major exchanges of goods and energy include things like military and essential services.

I’m making changes where I can, but I can’t just refuse medical services because my doctor doesn’t use a free-range organic MRI, and me bringing a reusable bag to the grocery store does nothing to reduce the amount of toxic waste the US military lights on fire every year.

I need internet, but there’s only one provider in my area. If my house is on fire or I call an ambulance, I don’t care what kind toxic gases are coming out of the first responder’s tailpipes.

I’ll still continue to fly less, buy less, drive my EV, swap my gas appliances, procure renewable electricity, and use more sustainable products. It’s not going to solve all of the worlds problems, but I do think collective action has the potential to drive a significant amount of the global transition to lower emissions.

The rest is done at the polls.
