If technology doesn't catch up, then we're doomed. But that's unlikely; there's nothing like a crisis to spur innovation. We're dealing with human nature here.

If technology doesn't catch up, then we're doomed. But that's unlikely; there's nothing like a crisis to spur innovation. We're dealing with human nature here. People have their own problems to deal with, and tend to ignore things that aren't an immediate concern. So you need to adjust their environment in a way that aligns their goals with some environmental goals, all without destroying your economy. Do it too fast or hard, and your economy crashes, and all environmental incentives go out the window as your country's focus changes to getting out of bankruptcy. It calls for finesse and timing.
