The planet is supposed to be reducing its greenhouse gas emissions. Instead, they have risen by 2.3 for the period 2000 to 2006. The UNFCCC cautions that emissions may be even worse now, noting that the statistics in the study are already nearly three years old. "UNFCCC expert review teams need two years to verify the data, partly by traveling to the countries concerned," says UNFCCC spokesman John Hay. "This makes the UNFCCC data not the freshest, but the most reliable on the market."
