Extended data table 1 | Comparison of committed emissions
Comparison of committed emissions by sector, estimated here and previously^8 ,^9 ,^11 –^13. Note that, in some cases, the totals may not correspond to the sum of the underlying sectors, owing to rounding.
*The age distribution of infrastructure is the same as in 2009, but annual emissions from the infrastructure were adjusted up to 2018 levels.
†The range represents the committed emissions estimated under the assumption of 30–50-year lifetimes for all sectors except transportation (12–18-year lifetimes).
