Google helps Amazon tribe get into carbon markets

Android to the Amazon's rescue. 

Smart phones running Google's operation system together with Google Earth satellite technology have helped the Surui tribe create a forest carbon inventory, says blog Mashable, and as a result have been approved to sell carbon credits.

Rio’s new take on carbon markets

Rio de Janeiro next year will launch a market for carbon credits with an interesting twist – it’s based primarily on forestry. Most emissions trading systems evolved from the 1980s campaign to cut pollution that was causing acid rain, and are generally focused on emissions of carbon dioxide from factories and power plants. Rio had talked about a system like this, but it didn’t make a huge amount of sense because most of Rio’s emissions come from cars and trucks and from illegal landfills.
