Current emission reduction pledges, after the close of the Cancun climate conference, fall short of what is needed to get the world on track for limiting global warming to 2 and 1.5°C above pre-industrial levels. Both of these warming limits are mentioned in the agreement. To keep warming limited to these targets, global total emissions need to drop below 44 billion tonnes CO2eq per year by 2020. After adding up reduction proposals of individual countries and taking into account accounting provisions, expected global emissions leave a gap of 12 billion tonnes CO2eq/yr by 2020. In Cancun, countries discussed a wide range of options that influence the size of the gap. If countries would implement the most stringent reductions they have proposed with most stringent accounting, the remaining ‘reduction gap’ would shrink to 8 billion tonnes CO2eq/yr, according to the Climate Action Tracker, a website that provides an independent assessment of individual counties’ emission reduction proposals and their aggregation. The Climate Action Tracker1 reflects the latest status of the progress being made at international climate negotiations. The team that performed the analyses followed peer-reviewed scientific methods (see publications in Nature and other journals)2 and significantly contributed to the UNEP Emissions Gap Report Mas info click briefing_paper_cancun.pdf
