I am simply quoting the UN NDC Synthesis Report:

The Parties’ [to the Paris Agreements 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.

…the estimates suggest the possibility of the Parties’ emissions peaking before 2030. 

[However,]

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.

[The possible good news]

Many Parties provided information on long-term mitigation visions, strategies and targets for up to and beyond 2050, referring to climate neutrality, carbon neutrality, GHG neutrality or net zero emissions. Mindful of the inherent uncertainty of such long-term estimates, the information indicates that:
•The Parties’ collective GHG emission level could be 87–93 per cent lower in 2050 than in 2017;
•Their annual per capita emissions are estimated at 0.5–1.0 t CO2 eq for 2050, which is 87–93 per cent lower than for 2017, suggesting that by 2050 these per capita emissions will be within the range implied in the 2 ºC and 1.5 ºC with low overshoot scenarios in the SR1.5.

[it would be nice if they stuck with a standardised base line such as 2010 or 1990 rather than shifted about.]
