a Net global GHG emissions aggregated with 100-year global warming potentials. b Marginal abatement costs. c Global mean temperature change relative to preindustrial levels. d Cumulative discounted mitigation costs in periods of 2020–2050 and 2050–2100 against cumulative net GHG emissions for respective periods.
