Figure 5f also shows that a peak emission rate of 11.5 GtC yr − 1 produces a peak rate of warming of 0.2 °C per decade, suggesting that the emission pathways in figure 5c with 2020 emissions of 11.5 GtC are peaking around the year 2020.

We see that, in cases where post-2050 emissions are small, the spread is much tighter, as shown by those pathways with cumulative emissions less than 0.3 TtC between 2010 and 2050.

The black bars show the spread in pathways with peak rates of emissions decline less than 4 %, while the grey bars show the spread in all emission pathways.

Figure 1 shows the temperature trajectories simulated by this model for 15 sample emission pathways.

The correlation is almost as strong if cumulative emissions out to 2500 are considered (shown in black squares in figure 3a) because the vast majority of the emissions in these zero emissions floor pathways have occurred by the time of peak warming.

As shown in figure 2e, f, the spread is very large for both of these metrics, and there is little correlation, except for the rapidly declining emission pathways (grey diamonds) appearing to the right of the slowly declining pathways (black crosses), as explained earlier.

The 15 emission trajectories are created by combining three possible pathways, shown here in black, with five possible emissions floors, shown here in coloured solid lines, as outlined in § 2a.

Based on the metrics presented in figure 2, we conclude that, for cases with no emissions floor, the strongest correlation across all pathways occurs between peak warming and the cumulative emissions from pre-industrial times to the time of that peak warming, as shown in figure 2a.

IEA analysis shows that on a 2 degree climate pathway, energy efficiency contributes nearly 40 % of global emissions reductions through 2050, the largest share of any fuel.
