I calculated my carbon footprint here. The results are quite shocking. The key reason is the number of flights I take. I guess it is absolutely necessary that Boeing and Airbus come out with their new planes. Another technology that will help is video conferencing (Cisco and Polycom). This is something which is quite here and now. Maybe Cisco should encourage regulators to put a carbon tax on long-distance flights. Cisco might also benefit from attempts to make utility grids more smarter. Can Cisco become the new climate evangelist?
Can GM seeds reduce carbon emissions? Due to higher productivity of these seeds, one can argue that total farmland area can reduce and still lead to higher food grain production. Farming is one of the biggest carbon emitters. It will also probably use lesser water, fertilizers, pesticides etc. Monsanto might also become a climate evangelist. That will be really interesting.
