![]() ![]() The $30 million project aims to protect trees from illegal logging and expanding palm oil plantations in Cambodia’s Keo Seima Wildlife Sanctuary and Indonesia’s Rimba Raya Biodiversity R eserve on the island of Borneo. Now the company is trying to make up for it by preserving more than 780 square miles of forest half a world away from its headquarters in Atlanta. energy use and of about 21% of total annual energy-related CO 2 emissions.Delta Air Lines emitted 14.3 million tons of carbon dioxide into the atmosphere in 2020. energy and accounted for 34% of total annual energy-related CO 2 emissions. energy consumption but petroleum was the source of 46% of total annual U.S. In 2021, petroleum accounted for about 36% of U.S. energy-related CO 2 emissions were from petroleum use in 2021 For example, for the same amount of energy produced, burning natural gas produces about half of the amount of CO 2 produced by burning coal. Because natural gas, which is mostly CH 4, has a high hydrogen content, combustion of natural gas produces less CO 2 for the same amount of heat produced from burning other fossil fuels. The amount of CO 2 produced (emitted) depends on the carbon content of the fuel, and the amount of heat produced depends on the carbon and hydrogen content. These reactions release heat, which we use for energy. When fossil fuels are combusted (burned), oxygen combines with carbon to form CO 2 and with hydrogen to form water (H 2O). The energy connectionįossil fuels consist mainly of carbon and hydrogen. human-caused (anthropogenic) greenhouse gas emissions. ![]() In 2020, fossil fuels were the source of about 73% of total U.S. The combined emissions of these other greenhouse gases accounted for about 21% of total U.S.
