Given the prominence of GHGs as the source for climate change, we won't free-market our way to a solution. Things have to change drastically, and rapidly, and regulation is probably the only reasonable avenue for making that happen in time. And more to the point: we need a lot of coordinated regulation across industries, multi-nationals, and countries to baseline our efforts. Almost all our GHGs come from fossil fuels, food and transportation industries. These stretch beyond borders, and we don't yet have enough momentum to stave off irreversible damages, tipping points, and unacceptable human suffering. And for every reminder from someone that "fossil fuels are convenient", I'll respond with "regulations are powerful".
