Residential buildings, the "last mile" sector in global decarbonization, have become most significant uncertain factor hindering carbon neutrality with increasing household energy demand. To track operational this study investigates Kuznets curve (CKC) and corresponding decoupling status of residential building operations at four emission scales by using data 30 countries from 2000 to 2019. The results show that (1) CKC model can fit more than half samples. Most curves an inverted U-shape, 76% per 82% total emissions. (2) In presence CKC, over four-fifths buildings peak regardless any scale. analysis denotes emissions developed reach their peaks earlier. emissions, samples' peaking proportion is 20% 25% income capita < 20,000 United States dollars (USD) 20,000–40,000 USD, respectively. (3) Tapio threshold regression effectively verify robustness heterogeneity CKCs, Strong effects CKCs are demonstrated floor space proves classic U-shaped relationship between economy doesn't exist all emitters. Overall, tracks historical trajectories a scale, providing reference for different economies simulate dynamic along economic booming.

As the two largest emerging emitters with highest growth in operational carbon emissions from residential buildings, historical emission patterns and decarbonization efforts of China India warrant further exploration. This study aims to be first present a intensity model considering end-use performances, assessing progress building over past decades using newest decomposing structural decomposition approach. Results indicate (1) annual increased by 1.4% 2.5% India, respectively, between 2000 2020. Household expenditure-related energy factors were crucial decarbonizing buildings. (2) Building electrification played significant role space cooling (−87.7 − 130.2 kg dioxide (kgCO2) per household India) appliances (∼ −169.7 ∼ −43.4 kgCO2 India). (3) collectively decarbonized 1498.3 399.7 M-tons CO2 operations, respectively. In terms intensity, (164.8 household) nearly caught up (182.5 2020 is expected surpass upcoming years, given country's robust rate 7.3%. Overall, this provides an effective data-driven tool for investigating potential offers valuable insights other economies seeking decarbonize buildings forthcoming COP281 age.

The transportation sector is the third-largest global energy consumer and emitter, making it a focal point in transition toward net-zero future. To accelerate decarbonization of passenger cars, this work first to propose bottom-up charging demand model estimate operational electricity use associated carbon emissions best-selling battery electric vehicles (BEVs) various climate zones China during 2020s. findings reveal that (1) top-20 selling BEV models China, such as Tesla, Wuling Hongguang, BYD, increased from 601 3054 giga-watt hours (GWh) 2020–2022, with BEVs South contributing more than half total demand; (2) 2020 2022, intensities decreased 1364 1095 kilowatt-hour per vehicle 797 621 kilograms dioxide (CO2) vehicle, respectively, North experiencing highest intensity decline compared other regions; (3) stocks 4774 12,048 GWh while rose 6.8 mega-tons CO2 reflecting an annual growth rate ~50%. In summary, delves into examination contrast benchmark data on nation-regional scale, well performance metrics related chargings. primary aim support nationwide efforts decarbonization, aiming for mitigation facilitating swift evolution cars carbon-neutral
