Question

Carbon dioxide (CO2) is the human-produced greenhouse gas that is the most significant contributor to global warming. Many critics of the climate change crisis like to point out that the United States is the not the biggest contributor of CO2. Should Americans work to reduce CO2 emissions, and instead focus on improving conservation efforts of China? Explain your position.

Answer 1

yes,Americans work to reduce CO2 emissions, and instead focus on improving conservation efforts of China

• Electricity. Electricity is a significant source of energy in the United States and is used to power homes, business, and industry. The combustion of fossil fuels to generate electricity is the largest single source of CO2 emissions in the nation, accounting for about 37% of total U.S. CO2emissions and 30% of total U.S. greenhouse gas emissions in 2014. The type of fossil fuel used to generate electricity will emit different amounts of CO2. To produce a given amount of electricity, burning coal will produce more CO2than oil or natural gas.
• Transportation. The combustion of fossil fuels such as gasoline and diesel to transport people and goods is the second largest source of CO2 emissions, accounting for about 31% of total U.S. CO2 emissions and 25% of total U.S. greenhouse gas emissions in 2014. This category includes transportation sources such as highway vehicles, air travel, marine transportation, and rail.
• Industry. Many industrial processes emit CO2 through fossil fuel combustion. Several processes also produce CO2 emissions through chemical reactions that do not involve combustion, for example, the production and consumption of mineral products such as cement, the production of metals such as iron and steel, and the production of chemicals. Fossil fuel combustion from various industrial processes accounted for about 15% of total U.S. CO2 emissions and 12% of total U.S. greenhouse gas emissions in 2014. Note that many industrial processes also use electricity and therefore indirectly cause the emissions from the electricity production.
