Consumption-Based CO2 Emissions Accounting And Scenario Simulation In Asia And Pacific Region
Abstract This study uses a consumer-based accounting approach to evaluate CO2 emission factors of 17 major Asia and Pacific countries that distribute all emissions in the supply chain to the commodity up to the final consumption location due to the influence 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 Pacific 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 efficient carbon-mitigation plans for governments and decision-makers. The accelerating economic growth and industrialization have posed significant challenges to global carbon-mitigation efforts and climate change response; as a result, each country has been provided a higher emphasis on CO2 emission. The Monte Carlo simulation technique has been used to create a dynamic scenario simulation model to investigate possible future peaks of Asia and Pacific countries' carbon emissions, considering the uncertainties of factors. The result shows that total consumption-based CO2 emissions are remarkable in the three Asian countries, including China (387451.95 metric tons (Mt) CO2), Japan (185259.60 Mt CO2), and India (100720.46 Mt CO2). In South Korea, Brunei, and Taiwan, annual consumption emissions are 1.77, 1.62, and 1.49 tons of CO2 per person. In terms of final 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 CO2 as per the dynamic scenario simulation. As for three other types of final demand, the government expenditure will possibly reach at highest 44.0 Gt CO2 by the next 30 years while the capital formation will probably hit its highest emissions at 149.5 Gt CO2.
