Abstract. Since 2000, CO2 emissions from emerging economies have outstripped those of developed economies. To limit global warming to under 1.5 °C by 2100, over 100 emerging economies have proposed net-zero carbon targets. Yet the supportive data are lacking - no inventory of CO2 emissions outlines detailed sources by sector or distribution at the subnational level for these economies. Here, we redress the balance by establishing a dataset for an energy-related CO2 emission inventory that covers 47 sectors and 8 energy types in 40 emerging economies (Cui et al., 2021). Their emissions, growing rapidly by 3.0 % per year, reached 7.5 Gt in 2019 and were sourced primarily in coal and oil (34.6 % and 28.1 %, respectively) and consumed by the power and transportation sectors. Meanwhile, among African countries in this group, biomass combustion was responsible for 34.7 %–96.2 % of emissions. Our dataset fills a data gap by providing a detailed, robust emissions accounting baseline for emerging economies — an advance that will support emissions-reduction policymaking at global, national and subnational levels.

Short summary
Emerging economies face challenges towards net-zero targets: inconsistencies in accounting calibers, missing raw data, non-transparent accounting methods, and a lack of detail on emissions. The authors established an accounting framework and compiled detailed inventories of energy-related CO2 emissions in 40 emerging economies, covering 47 sectors and eight energy types. The dataset will support emissions-reduction policymaking at global, national, and sub-national levels.
