The U.S. is the second largest emitter of CO2, with approximately 5.27 billion metric tons of carbon dioxide emission in 2012. The largest source of CO2 emissions in the U.S. comes from power generation, transportation and industry.

Who is the biggest contributor to global warming?

China. China emits almost twice the amount of greenhouse gases as the US, which it surpassed in 2006 as the world’s top contributor to atmospheric carbon dioxide. Today, the country accounts for approximately 23 percent of all global CO2 emissions.

What countries pollute the most?

Top 5 most polluting countries

  1. China (30%) The world’s most populated country has an enormous export market, which has seen its industry grow to become a serious danger to the planet.
  2. United States (15%) The world’s biggest industrial and commercial power.
  3. India (7%)
  4. Russia (5%)
  5. Japan (4%)

Where does most of the co2 come from?

Most Of The Rise In CO2 Likely Comes From Natural Sources. We know, from ice measurements, measurements at Mauna Loa, Hawaii, Barrow Alaska, and the South Pole, that atmospheric carbon dioxide has been increasing in our atmosphere since the beginning of the industrial age.

How much co2 do I produce?

7.8 + 57 + 5 + 0.8 = 70.6 tons of CO2 is the amount I produce per year based on my daily activities. The average person in the U.S. emits about 27 tons of CO2/year. 70 – 27 = 43 tons of CO2/year —> This means that I produce about 2.5x the amount of CO2 than the average person per year.

What are the main sources of co2 in the atmosphere?

There are both natural and human sources of carbon dioxide emissions. Natural sources include decomposition, ocean release and respiration. Human sources come from activities like cement production, deforestation as well as the burning of fossil fuels like coal, oil and natural gas.

Is co2 a pollution?

Carbon dioxide is not a pollutant. Carbon dioxide is not harmful to ordinary things, to human beings, or to animals, or to plants.

What of co2 is man made?

The greatest source of carbon dioxide in nature are the oceans. Annually, oceans will produce more CO2 than any natural or manmade source, by far. Carbon dioxide in the air is absorbed into the ocean, then is used by the life living in the ocean. Many organisms will use carbon dioxide in the water.

What are the 6 main greenhouse gases?

There are four main categories of fluorinated gases—hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3).

What are the 4 main greenhouse gases?

Unit 2: Atmosphere // Section 4: Major Greenhouse Gases. Many GHGs, including water vapor (the most important), ozone, carbon dioxide, methane, and nitrous oxide, are naturally present in the atmosphere. Other GHGs are synthetic chemicals that are emitted only as a result of human activity.

What are the 6 greenhouse gases?

It covers the accounting and reporting of the six greenhouse gases covered by the UNFCCC/Kyoto Protocol — currently, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocar- bons (PFCs), and sulphur hexafluoride (SF6), and nitrogen triflouride (NF3).

How can I reduce carbon dioxide in my home?

Steps to Reduce Exposure to Carbon Monoxide

  • Keep gas appliances properly adjusted.
  • Consider purchasing a vented space heater when replacing an unvented one.
  • Use proper fuel in kerosene space heaters.
  • Install and use an exhaust fan vented to outdoors over gas stoves.
  • Open flues when fireplaces are in use.

How do you calculate co2 emissions?

The sum is then 614 + 1638 = 2252 grammes of CO2/kg of L-gas. An average consumption of 5 kg / 100 km then corresponds to 5 kg x 2252 g/kg = 113 g CO2/km. High-calorific: 1 kg of H-gas consists for 72,7% of carbon, or 727 grammes of carbon per kg of H-gas.

How many tons of co2 does the average American produce?

The average annual carbon dioxide emissions per person, they found, was 20 metric tons, compared to a world average of four tons. But the “floor” below which nobody in the U.S. can reach, no matter a person’s energy choices, turned out to be 8.5 tons, the class found.

How much co2 does a car emit per mile?

A typical passenger vehicle emits about 4.6 metric tons of carbon dioxide per year. This assumes the average gasoline vehicle on the road today has a fuel economy of about 22.0 miles per gallon and drives around 11,500 miles per year. Every gallon of gasoline burned creates about 8,887 grams of CO2.
