Methane
Man is the biggest emitter of methane, releasing 330 teragrams (megatons, or million tons) every year. This comes from energy production, landfills, cattle raising, waste treatment and the burning of biomass. This compares with 20 tg from termites, and 15 tg from the oceans.
Carbon Dioxide (CO2)
Nature emits most Carbon Dioxide into the atmosphere, about 220 gigatons (thousand million tons) a year, though this is all removed by the carbon cycle. Human activities (the burning of fossil fuels (coal, oil and natural gas) and deforestation (cutting down trees which previously removed carbon dioxide from the atmosphere) is responsible for 11 gigatons a year. About 57% of this is removed by the carbon cycle (into the biosphere and the oceans) but the rest is gradually building up year by year with no way of removing it.
The United States for decades was the largest emitter of greenhouse gas, but within the last few years has been eclipsed by China. Per capita, the US remains one of the larger emitters of CO2.
China is currently the largest producer of greenhouse gases, responsible for approximately 28% of global emissions.
The largest contributors of greenhouse gases are China, the United States, and India. These countries have high emissions due to their large populations, industrial activities, and reliance on fossil fuels for energy production.
The greenhouse effect warms the gases in the atmosphere.
The glass or plastic walls of a greenhouse represent greenhouse gases in the atmosphere by trapping heat energy inside, much like how greenhouse gases in the Earth's atmosphere trap heat.

The US was for decades the largest single emitter of greenhouse gas. In the last few years China recently eclipsed the US as the largest emitter. China has about 4 times the population of the United States.

China is now the biggest emitter. The United States is the country that has emitted the most greenhouse gases.
carbon/greenhouse gases
China is currently the largest producer of greenhouse gases, responsible for approximately 28% of global emissions.
The largest contributor of greenhouse gases into the atmosphere is the oil and gas company Saudi Aramco. They have consistently been identified as one of the biggest emitters of carbon dioxide globally.
The energy sector, particularly electricity generation and transportation, is the largest emitter of greenhouse gases in terms of carbon dioxide equivalent. This is mainly due to the burning of fossil fuels such as coal, oil, and natural gas to meet energy demands.
China is the country that emits the most greenhouse gases, followed by the United States and India. This is largely due to their large populations and heavy reliance on coal and other fossil fuels for energy production.
What nation is the largest emitter of carbon dioxide?
The largest contributors of greenhouse gases are China, the United States, and India. These countries have high emissions due to their large populations, industrial activities, and reliance on fossil fuels for energy production.
