Paragrap 17 «Notes with
concern that the estimated
aggregate greenhouse gas emission levels in 2025 and 2030 resulting from the intended nationally determined
contributions do not fall within least - cost 2 ̊C scenarios but rather lead to a projected level of 55 gigatonnes in 2030, and also notes that much greater emission reduction efforts will be required than those associated with the intended nationally determined
contributions in order to hold the increase in the global average temperature to below 2 ̊C above pre-industrial levels by reducing emissions to 40 gigatonnes or to 1.5 ̊C above pre-industrial levels by reducing to a level to be identified in the special report referred to in paragraph 21 below;»
