Cover Story: Based on a quantitative estimate of the primary energy demand over 1965–2021, this study assesses the gains in energy efficiency and the savings in energy demand implied by the Chinese 2060 carbon neutrality pledge. This study implements a new methodology to robustly estimate the equilibrium energy demand, bootstrapped to forecast its expected probability distribution in 2060, allowing risk analysis. Although the energy demand is forecasted to become much higher than the official estimates, accounting for the objective to replace 85% of fossil sources with renewables and implementing the savings analysed in reliable international references, it is close to the official values. Finally, although it is feasible, it implies radical transformation, requiring unwavering political commitment. View this paper
