In developed countries, transportation and household energy use make up the largest component of an individual’s carbon footprint. For example, that same year France had a per capita carbon footprint of 6.0 metric tons (6.6 short tons), whereas Brazil and Tanzania had carbon footprints of 1.8 metric tons (about 2 short tons) and 0.1 metric ton (0.1 short ton) of CO 2 equivalent, respectively. Averages vary greatly around the world, with higher footprints generally found in residents of developed countries. According to the Carbon Dioxide Information Analysis Center and the United Nations Development Programme, in 2004 the average resident of the United States had a per capita carbon footprint of 20.6 metric tons (22.7 short tons) of CO 2 equivalent, some five to seven times the global average. The per capita carbon footprint is highest in the United States. As a result, a country’s carbon footprint can increase even as carbon emissions within its borders decrease. They include the emissions associated with goods that are imported into a country but are produced elsewhere and generally take into account emissions associated with international transport and shipping, which is not accounted for in standard national inventories. Rather than the greenhouse gas emissions associated with production, carbon footprints focus on the greenhouse gas emissions associated with consumption. Carbon footprint calculationĬarbon footprints are different from a country’s reported per capita emissions (for example, those reported under the United Nations Framework Convention on Climate Change). In contrast, a carbon footprint is usually expressed as a measure of weight, as in tons of CO 2 or CO 2 equivalent per year. It includes environmental impacts, such as water use and the amount of land used for food production. An ecological footprint is the total area of land required to sustain an activity or population. The carbon footprint concept is related to and grew out of the older idea of ecological footprint, a concept invented in the early 1990s by Canadian ecologist William Rees and Swiss-born regional planner Mathis Wackernagel at the University of British Columbia. In addition, the carbon footprint concept also often includes the emissions of other greenhouse gases, such as methane, nitrous oxide, or chlorofluorocarbons (CFCs). It includes direct emissions, such as those that result from fossil-fuel combustion in manufacturing, heating, and transportation, as well as emissions required to produce the electricity associated with goods and services consumed.
