Before the COP 21 in Paris, the Intended Nationally Determined Contributions (INDCs) were submitted by the countries. The UN has released a synthesis report on the aggregate effect of 119 INDCs.
This report gives an estimate of the aggregate greenhouse gases emission levels in 2025 and 2030.
This is a blogpost on the effect of these INDCs on global emissions.
The new synthesis report from the UN Framework Convention on Climate Change (UNFCCC) reveals answers to these questions and more. It finds that all countries have upped their ambition from their pre-2020 climate actions. It also finds that these climate plans are more complete and transparent than ever before. When looking at the combined effect of all of these INDCs, it finds that there is an aggregate reduction of approximately 4 GtCO2e in 2030.
Thus, there is progress, but this progress is not yet adequate to keep global average temperature rise below 2 degrees C (3.6 F). In the final weeks before Paris, this gap places great focus on the new international climate agreement itself, and what signals and provisions it can include to keep the 2 degrees C goal within sight. The Paris agreement will need to strengthen the pace and scale of the global transformation to a zero-carbon economy
