The Framework Convention on Climate Change (FCCC), adopted in May of 1992, calls for nations to take actions relative to their greenhouse gas emissions, including various commitments related to Land Use, Land Use Change, and Forestry, although these commitments are not legally binding.
Under Article 4, all Parties agreed to prepare greenhouse gas (GHG) inventories (article 4.1a), identify mitigation practices (article 4.1b), and transfer technologies and practices (article 4.1c). Article 4.1d singles out forestry and land use activities as follows:
4.1d Promote sustainable management, and promote and cooperate in the conservation and enhancement, as appropriate, of sinks and reservoirs of all greenhouse gases not controlled by the Montreal Protocol, including biomass, forests and oceans as well as other terrestrial, coastal and marine ecosystems.
Article 4.2 of the FCCC commits developed country Parties to take further action to "limit its anthropogenic emissions of greenhouse gases and protect and enhance its greenhouse gas sinks and reservoirs" (article 4.2a), to report on these activities to the FCCC (article 4.2b) using the "best available scientific knowledge" (article 4.2c).
Finally, Article 7.2 of the FCCC states that the Conference of the Parties shall "promote and guide development and periodic refinement of comparable methodologies" for inventories and mitigation technologies and practices.
