Carbon dioxide emissions are those stemming from the burning of fossil fuels and the manufacture of cement. They include carbon dioxide produced during the consumption of solid, liquid, and gas fuels and gas flaring.
Carbon dioxide (CO2) is a colorless, odorless and non-poisonous gas formed by the combustion of carbon and in the respiration of living organisms and is considered a greenhouse gas. Emissions means the release of greenhouse gases and/or their precursors into the atmosphere over a specified area and period of time.
Global emissions of carbon dioxide have risen by 99%, or on average 2.0% per year, since 1971, and are projected to rise by another 45% by 2030, or by 1.6% per year.
China and the USA are by far the biggest polluters in absolute volume of emissions while Australia, Canada and the USA are the dirtiest ones when measured per capita.
