This study uses a consumer-based accounting approach to evaluate CO 2 emission factors of 17 major Asia and Paci c countries that distribute all emissions in the supply chain to the commodity up to the nal consumption location due to the in uence of a country's consumption patterns. In addition, the number of emissions connected with each country's consumption of products and services, mainly in Asia and the Paci c countries, has received little attention. This study contributes to understand the effects of the country's consumption of products and services on carbon emission peaks and formulate e cient carbon-mitigation plans for governments and decision-makers. The accelerating economic growth and industrialization have posed signi cant challenges to global carbon-mitigation efforts and climate change response; as a result, each country has been provided a higher emphasis on CO 2 emission. The Monte Carlo simulation technique has been used to create a dynamic scenario simulation model to investigate possible future peaks of Asia and Paci c countries' carbon emissions, considering the uncertainties of factors. The result shows that total consumption-based CO 2 emissions are remarkable in the three Asian countries, including China (387451.95 metric tons (Mt) CO 2 ), Japan (185259.60 Mt CO 2 ), and India (100720.46 Mt CO 2 ). In South Korea, Brunei, and Taiwan, annual consumption emissions are 1.77, 1.62, and 1.49 tons of CO 2 per person. In terms of nal consumption, the household sector is the supreme noteworthy donor to consumption-based emissions, accounting for 27-56%. The household sector probably peak at 19.7 Gt CO 2 as per the dynamic scenario simulation. As for three other types of nal demand, the government expenditure will possibly reach at highest 44.0 Gt CO 2 by the next 30 years while the capital formation will probably hit its highest emissions at 149.5 Gt CO 2 .
