What are the 3 major causes of global warming emissions?

Causes for rising emissions

• Burning coal, oil and gas produces carbon dioxide and nitrous oxide.
• Cutting down forests (deforestation).
• Increasing livestock farming.
• Fertilisers containing nitrogen produce nitrous oxide emissions.
• Fluorinated gases are emitted from equipment and products that use these gases.

What are the top 3 contributors to CO2 emissions?

China, the United States, and the nations that make up the European Union are the three largest emitters on an absolute basis. Per capita greenhouse gas emissions are highest in the United States and Russia.

Which is the largest contributor to global pollution?

Electricity and Heat Production (25\% of 2010 global greenhouse gas emissions): The burning of coal, natural gas, and oil for electricity and heat is the largest single source of global greenhouse gas emissions.

Which gas has the highest global warming potential?

Gases with high GWPs will warm the Earth more than an equal amount of CO2 over the same time period….Source.

Greenhouse gas	Carbon Dioxide
Chemical formula	CO2
Global Warming Potential, 100-year time horizon	1
	100*

Which sector has the second highest global greenhouse gas emission?

Electricity production (25 percent of 2019 greenhouse gas emissions) – Electricity production generates the second largest share of greenhouse gas emissions. Approximately 62 percent of our electricity comes from burning fossil fuels, mostly coal and natural gas.

Which gas has least global warming potential?

Some have high GWP but only a low concentration in the atmosphere. The total impact of all fluorinated gases is estimated at 3\% of all greenhouse gas emissions….Values.

GWP values and lifetimes	Sulfur hexafluoride SF 6
Lifetime (years)	3,200
Global warming potential, GWP	20 years	16,300 17,500
100 years	22,800 23,500
