Greenhouse gas (ghg) emissions from human activities add to the greenhouse effect, causing climate change.

Carbon dioxide is the main contributor to GHG emissions (over 75% of emissions), though methane, nitrous oxide are also important greenhouse gasses emitted in substantial amounts.

The largest contributors to GHG emissions (by nation) are China, the US, the EU, India, and Russia.

The Organization of the Petroleum Exporting Countries (OPEC) includes state-owned oil and gas companies, who are indirectly responsible for a large portion of global GHG emissions caused by the burning of the exported fossil fuels.
