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 added]
