As part of the Copenhagen Accord, Annex I Parties (industrialised countries) and non-Annex I Parties (developing countries) have submitted reduction proposals (pledges) and mitigation actions to the UNFCCC secretariat. Our calculations show that if the current reduction offers of Annex I and non-Annex I countries are fully implemented, global greenhouse gas emissions could amount to 48.6–49.7 GtCO2eq by 2020. Recent literature suggests that the emission level should be between 42 and 46 GtCO2eq by 2020 to maintain a “medium” chance (50–66%) of meeting the 2 °C target.
