Which three sectors contribute most to greenhouse gas emissions?
Since 1990, three sectors stand out as the fastest-growing sources of greenhouse gas emissions: Industrial processes grew by 187\%, transportation (a subsector of energy) by 79\% and manufacturing and construction (also a subsector of energy) by 56\%.
WHO releases the most greenhouse gases every year?
China is the world’s largest contributing country to CO2 emissions—a trend that has steadily risen over the years—now producing 10.06 billion metric tons of CO2.
Which sector contributes the most to global emissions?
Here we see that electricity and heat production are the largest contributor to global emissions. This is followed by transport, manufacturing and construction (largely cement and similar materials), and agriculture.
Which sector is responsible for the most carbon emissions?
Here are the top five carbon-intensive sectors:
- Energy Production. The burning of fossil fuels for energy production is single-handedly the biggest source of carbon dioxide emissions.
- Agriculture, Forestry and Other Land Use (AFOLU)
- Industry.
- Transport.
- Residential, Commercial and Institutional Sectors.
What is the country that emits the most greenhouse gasses and why?
China
China has the highest greenhouse gas emissions of any country in the world. In 2017, China emitted 9.3 billion tons of carbon dioxide. China faces widespread criticism from the international community about its carbon footprint and is pressured to control its growing emission levels.
What contributes the most to global warming?
Indeed, carbon dioxide, a byproduct of fossil fuel combustion, is the principal greenhouse gas contributing to global warming. However, other greenhouse gases including methane, nitrous oxide, and a number of industrial-process gases also are important contributors to climate change.
What are the major greenhouse gases and their sources?
Main Greenhouse Gases
| Greenhouse gas | Major sources |
|---|---|
| Carbon Dioxide | Fossil fuel combustion; Deforestation; Cement production |
| Methane | Fossil fuel production; Agriculture; Landfills |
| Nitrous Oxide | Fertilizer application; Fossil fuel and biomass combustion; Industrial processes |
| Chlorofluorocarbon-12 (CFC-12) | Refrigerants |

How much greenhouse gas does the US emit?
In 2019, the United States emitted 6.6 billion metric tons of greenhouse gases (CO2e). Carbon dioxide accounted for the largest percentage of greenhouse gases (80\%), followed by methane (10\%), nitrous oxide (7\%), and other greenhouse gases (3\%).
Who are the biggest greenhouse gas emitters?
Most of the world’s greenhouse gas emissions come from a relatively small number of countries. 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 developing countries produce the most greenhouse gases?
