UNFCCC
Article 2 Objective
The ultimate objective of this Convention . . . is to achieve, in
accordance with the relevant provisions of the Convention, stabilization
of greenhouse gas concentrations in the atmosphere at a level that
would prevent dangerous anthropogenic interference with the climate
system.[emphasis added]
Article 4 Commitments
1. (b) Formulate, implement, publish and regularly update national and,
where appropriate, regional programmes containing measures to
mitigate climate change by addressing anthropogenic emissions by
sources and removals by sinks of . . . greenhouse gases . . . and
measures to facilitate adequate adaptation to climate change; [emphasis
