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 activity, energy demand, and progress toward climate objectives.
Taiwan recorded 282.10 million tonnes of energy and process greenhouse gas emissions in 2015, increasing to 286.40 million tonnes in 2016 and 292.30 million tonnes in 2017. Emissions eased slightly to 290.30 million tonnes in 2018 before declining to 284.80 million tonnes in 2019, indicating gradual moderation in greenhouse gas output. In 2020, emissions fell further to 271.50 million tonnes as industrial activity and energy demand weakened during the pandemic. Economic recovery contributed to emissions rebounding to 287.10 million tonnes in 2021. However, emissions declined again to 279.10 million tonnes in 2022 and reached 270.80 million tonnes in 2023, representing the lowest level recorded during the review period.
Overall, the dataset highlights a gradual long-term decline in greenhouse gas emissions despite temporary fluctuations associated with economic cycles and post-pandemic recovery. The sustained reduction reflects improvements in energy efficiency, cleaner industrial processes, and ongoing efforts to lower carbon intensity while supporting continued economic development.
The dataset provides valuable insights for monitoring national greenhouse gas performance, evaluating emissions from industrial and energy-related activities, and assessing progress toward climate and decarbonization objectives. It also supports sustainability assessments, environmental planning, regional comparisons, and long-term emission forecasting, enabling policymakers, researchers, and industry stakeholders to strengthen emission reduction strategies and guide Taiwan's transition toward a more sustainable, lower-carbon economy.
