The politically correct answer is all countries are responsible for GHG emissions. However the top contributors of carbon dioxide in 2010 are:
World total: 27 Billion tonnes/ year
USA : 6 Billion tonnes/year (22.2%)
China: 5 Billion tonnes/year (18.4 %)
European Union: 4 Billion tonnes/year (14.7%)
All the rest of the world (+150 countries) produces the other 50% of the carbon dioxide
China has become the world leader in emitting CO2. China currently emits 24% of the world's CO2 that enters the atmosphere.
1 kg of wood
It absorbs Co2 through the process of Photosythisis.
No. Plants emit their own CO2 through respiration.
A small bus can emit 270 grams of carbon dioxide per kilometre. (Australian figures). This might be the equivalent of about 21 tonnes of Carbon dioxide (CO2) a year for a bus driving 60,000 km (36,000 miles).
There are smallamount of volcanoes. They emit so2 and co2 gases.
china
Too much !
1% of the worldds emissions
double the amount as planes.
i dont know do the math
some, but much less than the amount it absorbs. Also, as an alternative to fertilizer, it reduces co2 (fertilizer production admits a lot of co2)
Animals emit CO2 when they exhale.
It absorbs Co2 through the process of Photosythisis.
No. Plants emit their own CO2 through respiration.
Yes, infact vehicles are considered to be the main contributor to the Co2 in the atmosphere
Once a flower is cut and starts dying it does emit CO2 as it decomposes.
A tiny miniscule of fuel plus a lot of rice
It depends on the model. A typical truck emits 30 or more POUNDS of CO2 for 15-20 miles.
