Guys, does anyone know the answer?
get which of the following are the largest contributor to global pollution from screen.
Causes and Effects of Climate Change
Causes and Effects of Climate Change
Fossil fuels – coal, oil and gas – are by far the largest contributor to global climate change, accounting for over 75 per cent of global greenhouse gas emissions and nearly 90 per cent of all carbon dioxide emissions.
As greenhouse gas emissions blanket the Earth, they trap the sun’s heat. This leads to global warming and climate change. The world is now warming faster than at any point in recorded history. Warmer temperatures over time are changing weather patterns and disrupting the usual balance of nature. This poses many risks to human beings and all other forms of life on Earth.

Sources of Greenhouse Gas Emissions
On this page:Overview Electric Power Transportation Industry
Commercial/Residential
Agriculture Land Use/Forestry
Overview
Total Emissions in 2020 = 5,981 Million Metric Tons of CO2 equivalent. Percentages may not add up to 100% due to independent rounding.
* Land Use, Land-Use Change, and Forestry in the United States is a net sink and removes approximately 13% of these greenhouse gas emissions. This net sink is not shown in the above diagram. All emission estimates from the Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990–2020.

Greenhouse gases trap heat and make the planet warmer. Human activities are responsible for almost all of the increase in greenhouse gases in the atmosphere over the last 150 years.1 The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation.
EPA tracks total U.S. emissions by publishing the Inventory of U.S. Greenhouse Gas Emissions and Sinks. This annual report estimates the total national greenhouse gas emissions and removals associated with human activities across the United States.
The primary sources of greenhouse gas emissions in the United States are:
Transportation (27% of 2020 greenhouse gas emissions) – The transportation sector generates the largest share of greenhouse gas emissions. Greenhouse gas emissions from transportation primarily come from burning fossil fuel for our cars, trucks, ships, trains, and planes. Over 90% of the fuel used for transportation is petroleum based, which includes primarily gasoline and diesel.2
Electricity production (25% of 2020 greenhouse gas emissions) – Electric power generates the second largest share of greenhouse gas emissions. Approximately 60% of our electricity comes from burning fossil fuels, mostly coal and natural gas.3
Industry (24% of 2020 greenhouse gas emissions) – Greenhouse gas emissions from industry primarily come from burning fossil fuels for energy, as well as greenhouse gas emissions from certain chemical reactions necessary to produce goods from raw materials.
Commercial and Residential (13% of 2020 greenhouse gas emissions) – Greenhouse gas emissions from businesses and homes arise primarily from fossil fuels burned for heat, the use of certain products that contain greenhouse gases, and the handling of waste.
Agriculture (11% of 2020 greenhouse gas emissions) – Greenhouse gas emissions from agriculture come from livestock such as cows, agricultural soils, and rice production.
Land Use and Forestry (13% of 2020 greenhouse gas emissions) – Land areas can act as a sink (absorbing CO2 from the atmosphere) or a source of greenhouse gas emissions. In the United States, since 1990, managed forests and other lands are a net sink, i.e., they have absorbed more CO2 from the atmosphere than they emit.
Emissions and Trends
Since 1990, gross U.S. greenhouse gas emissions have decreased by 7%. From year to year, emissions can rise and fall due to changes in the economy, the price of fuel, and other factors. In 2020, U.S. greenhouse gas emissions decreased 11% compared to 2019 levels. The sharp decline in emissions was primarily from CO2 emissions from fossil fuel combustion and was largely due to the coronavirus (COVID-19) pandemic-related reductions in travel and economic activity, including a 13% decrease in transportation emissions driven by less travel due to the COVID-19 pandemic. Electric power sector emissions decreased 10% due to a slight decrease in electricity demand from the COVID-19 pandemic and a continued shift from coal to less carbon-intensive natural gas and renewables.
Note: All emission estimates from the Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990–2020.
