Hong Kong Greenhouse Gas Emissions: Source-Level Data Since 2021

Climate TRACE provides greenhouse gas and air pollutant emission estimates for Hong Kong SAR, covering annual country-level data since 2015 and monthly source-level data since 2021. The inventory tracks emissions across specific sub-sectors and gases for over 2.7 million sources globally, incorporating asset-level ownership where available. This dataset is maintained by the Climate TRACE coalition and was last updated in March 2026.

Use Cases

• Analyzing temporal trends in greenhouse gas emissions using the monthly source-level data
• Identifying high-emission sub-sectors within Hong Kong SAR using the annual country-level aggregates
• Assessing the reliability of modeled emission estimates using the provided confidence scores

Strengths

• Includes source-level confidence scores for reliability assessment
• Provides asset ownership data for specific emission sources
• Granular monthly temporal resolution for source-level data since 2021

Limitations

• Emissions are modeled estimates rather than direct sensor measurements
• Source ownership data is inconsistent and only provided where available
• Specific column headers and schema are not explicitly defined in the metadata
