The third session of the Ad Hoc Group on the Berlin Mandate (AGBM 3) was held in Geneva from 5-8 March 1996. Delegates heard a number of new, specific proposals on new commitments for Annex I Parties, including a two-phase CO2 emissions reduction target proposed by Germany. They also discussed how Annex I countries might distribute or share new commitments, and whether those should take the form of an amendment or protocol. Developing countries raised questions on whether policies and measures under discussion would represent barriers to trade. Delegates agreed to compile proposals for new commitments for consideration at the next session of the AGBM, and to hold informal roundtable discussions on policies and measures as well as on quantitative emissions limitation and reduction objectives.
