Last year set new record for carbon emissions
WASHINGTON, D.C. — "In 2005, carbon emissions from the burning of fossil fuels climbed to a record high of 7.9 billion tons, an increase of some 3 percent from the previous year.
"Annual global emissions have been increasing since the beginning of the Industrial Revolution in the late eighteenth century, when humans first began burning fossil fuels on a large scale to produce energy. Since the early 1900s, emissions have been rising at an increasingly rapid pace. Annual emissions have grown by a factor of fifteen since 1900, advancing nearly 3 percent a year over that time," says Joseph Florence of the Earth Policy Institute.
Half of all energy-related carbon emissions come from only four countries. The United States, with less than 5 percent of the world's population, accounts for 21 percent of carbon emissions. It is followed by China, which emits 18 percent. Other major contributors to global carbon emissions are Russia, Japan, India, Germany, and Canada.
Qatar, with 14 tons of carbon emitted per person, leads the world in per capita emissions. The United States, Australia, and Canada each emit roughly 5 tons of carbon per person each year. This is five times the figure in China and 17 times that in India.
Some 40 percent of energy-related emissions come from the burning of fossil fuels, such as oil, coal, and natural gas, to generate electrical power. The transportation sector is the second-largest source worldwide, responsible for 20 percent of all carbon emitted. Residential and commercial buildings, industry, and a variety of minor uses account for the rest.
As global emissions of carbon increase, they raise the levels of carbon dioxide (CO2) in the atmosphere. The average atmospheric concentration of CO2 reached 380 parts per million by volume in 2005, up 2.2 parts per million from 2004 levels and up 103 parts per million from pre-industrial times. The Intergovernmental Panel on Climate Change (IPCC) estimates that the current atmospheric CO2 concentration has not been exceeded over the last 420,000 years and probably not during the past 20 million years.
