Fossil fuels

Fuels such as oil, natural gas, and mineral coal – fossilized plant residues – that are buried in the Earth’s crust and reached their present state through chemical reactions over long periods of time. They are produced by the continuous decomposition of organic animal and plant matter through geological eras. Their production is extremely slow – much slower than the current consumption rate – and therefore, not renewable on the human timescale.

Leakage or escape

It corresponds to the increase of greenhouse gas emissions that occur outside the limit of the clean development mechanism (CDM) project activity and which, at the same time, is measurable and attributable to the project activity. The leakage is deducted from the...

CDM Project Activities

CDM Project Activities

Activities that are part of a candidate CDM project and that provide a reduction in the emission of greenhouse gases or an increase in the removal of CO2. (see question 20 of the ABC of Changes)

Anthropogenic emissions

Anthropogenic emissions

Emissions produced as a result of human action. For example, large amounts of carbon dioxide are being released into the atmosphere by activities such as the burning of fossil fuels, agriculture, cement making, and so on.
