Better zoning could eliminate a huge amount of commuting emissions. A cultural shift away from in-person meetings as signalling, and travel as a substitute for personality, could eliminate a huge amount of air travel emissions. Meat consumption can be drastically reduced. The changes we need aren't actually all that big.
