Tonga: Greenhouse Gas and Air Pollutant Emissions Since 2015

Tonga's greenhouse gas and air pollutant emissions are estimated at both country and source levels by the Climate TRACE coalition. The data includes annual records starting in 2015 and monthly source-level observations beginning in 2021, categorized by sub-sector and gas type.

Use Cases

• Tracking Tonga's progress toward climate goals using annual country-level emissions by gas type
• Identifying high-emission facilities using monthly source-level data and sub-sector labels
• Assessing data reliability for policy making using the confidence scores provided for each source

Strengths

• Granular monthly source-level data since 2021
• Includes confidence scores for emission estimates
• Categorized by specific sub-sectors and gas types

Limitations

• Emissions are estimates derived from modeling rather than direct sensor measurements
• Temporal gap between country-level (2015) and source-level (2021) start dates
