We are especially grateful to the provid- ers of data used in this report and in WRI’s Climate Analysis Indicators Tool (CAIT). This includes BP, the Carbon Dioxide Information Analysis Center, the Dutch National Institute of Public Health and the Environ- ment (RIVM), Richard Houghton, the Intergovernmental Panel on Climate Change, the International Energy Agency, the United Nations Development Programme, the UN Framework Convention on Climate Change, the U.S. Energy Information Administration, the U.S. Environmental Protection Agency, the World Bank, and the World Economic Forum. We owe particular gratitude to the many individuals that helped develop and test CAIT—the data and analysis tool that served as the basis for much of this report. Matthew Markoff, Odile Blanchard, Niklas Höhne, and Harald Winkler made especially significant contributions.
