CO2 emissions from cars, factories, and power plants grew at an annual rate of 1.1 percent during the 1990s, according to the Global Carbon Project, which is a data clearinghouse set up in 2001 as a cooperative effort among UN-related groups and other scientific organizations. But from 2000 to 2004, CO2 emissions rates almost tripled to 3 percent a year – higher than any rate used in emissions scenarios for the reports by the Intergovernmental Panel on Climate Change (IPCC).
