The oceans.
China
Oceans act as a carbon sink, in fact they are the largest carbon sink absorbing about 1/4 of the CO2 we put into the air. However, with global warming considering that CO2 dissolves better in cold water there is a worry that the oceans will not be able to hold as much CO2 and will begin to release it into the atmosphere
O=C=O carbon dioxide
The largest non-organic cause of CO2 release is volcanic activity. In fact a single large eruption can produce more CO2 for the year than human activity does (Mt. St. Helens, for example).
Chile is the largest producers of copper.
Producers
Yes. Uzbekistan is one of the worlds largest cotton producers
One of the worlds largest copper producers in Africa is Zambia.
They are co2 producers, although they do have a smaller carbon footprint...
China
co2 is exhaled during respiration & producers take it in during photosynthesis
India and Guatemala are the worlds largest producers. Colombia and Vietnam are smaller cardamom producers

Producers (trees) give of alot of oxygen, they get their energy from the sun though.
