Pieter Tans in the interview to the New York Times [1] said that he was cautiously optimistic about the new commercial venture of the Earth Networks. (This company is going to deploy a network of 100 greenhouse gas sensors around the planet for pinpointing emissions sources.) Emissions sooner or later are going to be worth money, and therefore transparency of the monitoring system does matter. Currently all greenhouse gas data and model results from the NOAA lab that Dr. Tans works in are freely available. He is worried that a portion of the transparency may disappear, when data will be provided by a commercial company.
