Data definition
Energy & Process GHG Emissions — - Energy & Process GHG Emissions refer to the total greenhouse gas (GHG) emissions generated from energy-related activities and industrial processes within a given year. The indicator is typically expressed in million tonnes of carbon dioxide equivalent (MtCO₂e) and combines emissions from fossil fuel combustion, industrial energy use, and process-related activities into a single measure using global warming potential (GWP) factors. It provides a comprehensive assessment of emissions associated with energy production, energy consumption, and industrial manufacturing, making it a key indicator for evaluating a country's environmental impact, industrial development, and progress toward climate mitigation objectives.
The data includes greenhouse gas emissions from the combustion of fossil fuels such as coal, oil, and natural gas across all major sectors, including electricity and heat generation, manufacturing, transportation, residential, commercial, and other energy-consuming activities. It also includes emissions from industrial processes that are not directly related to fuel combustion, such as cement production, lime manufacturing, chemical production, metal processing, and other process-related industrial activities. The indicator incorporates major greenhouse gases, including carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), and, where applicable, fluorinated gases, expressed as carbon dioxide equivalent (CO₂e) using internationally recognized global warming potential factors. Data is compiled using standardized international methodologies to ensure consistent reporting and comparability across countries and over time.
The data excludes greenhouse gas emissions from agriculture, forestry, land-use change and forestry (LULUCF), waste management, and other non-energy sectors unless explicitly included within the reporting methodology. It does not account for carbon removals through forests, carbon capture, utilization and storage (CCUS), or other negative emission technologies. The indicator excludes indirect emissions embodied in imported goods and services and does not measure sector-specific emission intensity, per capita emissions, or energy efficiency. Variations in national reporting practices, industrial classifications, emission factors, and estimation methodologies may result in minor differences in reported values across countries.

It provides a comprehensive assessment of emissions associated with energy production, energy consumption, and industrial manufacturing, making it a key indicator for evaluating a country's environmental impact, industrial development, and progress toward climate mitigation objectives.
Measured in million tonnes, the dataset reflects greenhouse gas emissions generated from energy production, fuel combustion, and industrial process activities, making it an important indicator of environmental performance, industrial growth, energy demand, and progress toward climate objectives.
Asia-Pacific recorded 17,667.20 million tonnes of energy and process greenhouse gas emissions in 2015, remaining nearly stable at 17,633.70 million tonnes in 2016 before increasing to 18,169.30 million tonnes in 2017, 18,784.40 million tonnes in 2018, and 19,280.40 million tonnes in 2019. Emissions moderated slightly to 19,013.00 million tonnes in 2020 before rising to 19,808.60 million tonnes in 2021, 20,081.80 million tonnes in 2022, and a record 21,057.60 million tonnes in 2023. China remained the largest contributor throughout the review period, while India recorded the fastest absolute growth. Significant contributions also came from Japan, South Korea, Indonesia, Australia, Malaysia, Thailand, Taiwan, Vietnam, the Philippines, and remaining Asia-Pacific countries, each influencing the region's overall emissions trajectory through varying industrial activity and energy consumption patterns.
Overall, the dataset indicates a sustained long-term increase in greenhouse gas emissions across Asia-Pacific, reflecting expanding industrialization, urbanization, manufacturing activity, and electricity demand despite temporary disruptions in 2020. The dataset supports monitoring regional greenhouse gas performance, evaluating industrial and energy-sector emissions, assessing progress toward decarbonization and climate policy objectives, conducting sustainability and regional comparisons, and forecasting future emission trends. It also provides policymakers, researchers, and industry stakeholders with a reliable foundation for evaluating emission reduction strategies and guiding long-term environmental planning.
