Well, there's good reason to hope on the carbon emissions front.
The global trend toward replacing coal with natural gas will have a massive impact on human CO2 footprint. And this isn't the result of the strangling hand of regulation either: gas plants are simply more economically efficient and easy to run. It also coincidentally generates less than half the CO2 per kwH that coal does.
This trend alone makes hitting world CO2 goals a lot more feasible. A better electricity grid will allow more diverse energy sources as well. It's really quite feasible to increase electricity production while reducing CO2 emissions.
