Transportation (28% of 2021 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.
What is the biggest source of carbon dioxide emissions?
Carbon dioxide (CO2): Fossil fuel use is the primary source of CO2. CO2 can also be emitted from direct human-induced impacts on forestry and other land use, such as through deforestation, land clearing for agriculture, and degradation of soils.
What is the share of the world’s co2 emissions?
CO2 Emissions by Country
| # | Country | Share of world |
|---|---|---|
| 1 | China | 29.18% |
| 2 | United States | 14.02% |
| 3 | India | 7.09% |
| 4 | Russia | 4.65% |
Which sector has the largest co2 emissions worldwide?
According to S&P Global's analysis of 2019-2020 average emissions intensity by sector, utilities is the most carbon-intensive sector in the world, emitting a staggering 2,634 tonnes of CO2 per $1 million of revenue. Materials and energy sectors follow behind, with 918 tonnes and 571 tonnes of CO2 emitted, respectively.
Who are the top 3 contributors to co2 emissions?
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.

What is the largest share of CO2 emissions?
Who emits more than their share of CO2 emissions?
The USA has emitted most to date: more than a quarter of all historical CO2: twice that of China which is the second largest contributor.
What percentage of carbon emissions come from the US?
In 2021, global carbon dioxide emissions reached a record-high of 37.1 billion metric tons (GtCO₂), of which the U.S. accounted for 14 percent. Americans also had a carbon footprint roughly three times the global average that year, at 14.9 tCO₂.
