You're right, but the more people are able to make good choices, the more politicians will be able to put pressure on companies who make money on carbon emissions. Politicians can't do anything unless consumers really show they're able to change. Climate change is a problem of consumption and how economies are completely dependent on carbon emissions. You just cannot realistically forbid this and this without hurting the economy and its existing carbon-dependent infrastructure. Climate change will be fought on campaigning on consumers so that they call on their good will and shift markets. I guess the only reliable way to make consumers change their choice is fear mongering about climate change. We need more climate change hard-scifi. If consumers act like lazy sedentary irresponsible kids, the only way will be to instate hard measures: banning personal cars and adding more organized public transport, switching to reusable glass and steel packaging, reducing bullshit jobs to avoid useless transportation, economies of scale to avoid emissions, a big nuclear energy plan, etc. To be honest all those things should already be startups. They're not complicated. It's a matter of law and how salesmen are pushing consumers to make bad choices.
