Are Developing Countries Satisfied with Half Filled Promises?
Last week’s UN Environment Emissions Gap Report showed that the world’s ‘distance to target’ on carbon emissions continues to grow. The gap between current NDCs and the 1.5 and 2 degree trajectories ranges between a huge 11 and 19 gigatons of CO2 equivalent emissions for 2030, 20-35% of present emissions.
Scientists suggest that the even with full implementation of current NDCs 80% of the carbon budget for 2 degrees will be depleted by 2030, and would be fully depleted for the 1.5 degree target. And that is if countries actually fulfill their NDC commitments, which is in doubt for the US, Indonesia, Australia, and several others.
The conclusion is that current NDCs are not enough. Governments already know that their combined pledges for 2030 are insufficient, particularly those of industrialised countries. The IPCC Special Report in autumn 2018 will show this ever more clearly, but governments should not wait for this to act.
There is good news, however. Global CO2 equivalent emissions — not just energy-related CO2 — seem to have plateaued between 2014 to 2016. Moreover, there is growing potential for cost-effective carbon cuts, defined as below $US100/ton CO2, until 2030. This means that the number of policies with minimal or even negative costs have been growing significantly.
