In 2010, global greenhouse gas emissions were 47.9 Gt compared to 35.8 Gt in 1990. Apart from the growth in international transport, this increase stemmed exclusively from industrialization in developing, non-Annex I countries1, 2. Every year, the Conference of the Parties to the UNFCCC continues to seek an agreement that will decisively reduce the growing greenhouse gas emissions. Focus has been placed on the distribution of responsibilities and actions to address the challenges, guided by the principle of common but differentiated responsibilities.
