A new synthesis report by the UN indicates that the global CO2 emissions will decline by just 0.5% by 2030 relative to 2010 levels. The goalis to reduce CO2 levels by 45% below 2010 levels in the year 2030 in order to limit the global mean temperature to 1.5 degrees C. above pre-industrial levels. We are at about 1.1 degrees C. above pre-industrial levels now and a global mean temperature (GMT) that rises above 1.5 degrees C.and stays above 1.5 degrees C. is not considered safe.
One reason for this post is to counter the naive argument that science and capitalism will solve the problem and that government action is not needed.
Here is an article to read by the BBC:

This is from the NDC synthesis report:

The Parties’ total GHG emissions are, on average, estimated to be:
:By 2025, 2.0 per cent higher than the 1990 level (13.77 Gt CO2 eq), 2.2 per cent higher than the 2010 level (13.74 Gt CO2 eq) and 0.5 per cent higher than the 2017 level (13.97 Gt CO2 eq);
•By 2030, 0.7 per cent lower than in 1990, 0.5 per cent lower than in 2010 and 2.1 per cent lower than in 2017.
According to the SR1.5, to be consistent with global emission pathways with no or limited overshoot of the 1.5 °C goal, global net anthropogenic CO2 emissions need to decline by about 45 per cent from the 2010 level by 2030, reaching net zero around 2050. For limiting global warming to below 2 °C, CO2 emissions need to decrease by about 25 per cent from the 2010 level by 2030 and reach net zero around 2070. Deep reductions are required for non-CO2 emissions as well. Thus, the estimated reductions referred to above fall far short of what is required, demonstrating the need for Parties to further strengthen their mitigation commitments under the Paris Agreement.
