Google exposes some of the indicators nicely in charts based on the data exposed by worldbank
I have checked few indicators across few countries. Here are the links of couple of charts.
CO2 emissions - USA, India, and China
Electric Power Consumption - USA, India, and China
Seeing all, Actually USA and the developed nations has to contribute a lot to save the environment.
Check out the other indicators either through the worldbank datafinder or Google Publicdata charts or develope your own way of rendering the data using the worldbank API
