It's difficult to give a detailed answer. I will try to give you a more general one.
Greenhouse gases are essentially caused by carbon dioxide, or CO2. The energy sector produces more CO2 than any other sector of society. We believe that the best way to solve the problem is to develop systems which could capture CO2 and store it. The technology to do this already exists, but the government and the private sector must invest more to develop it further.
The greatest progress we could achieve would be to basically capture and store the CO2 produced by the energy sector.
