American Samoa Greenhouse Gas Emissions: Source-Level Data Since 2021

Climate TRACE provides greenhouse gas and air pollutant emission estimates for American Samoa, featuring annual country-level data since 2015 and monthly source-level data since 2021. The inventory tracks emissions across specific sub-sectors and gases, derived from a global monitoring effort of over 2.7 million sources. This dataset is maintained by the Climate TRACE coalition and was last updated in March 2026.

Use Cases

• Analyzing temporal trends in American Samoa's emissions using the monthly source-level data
• Comparing greenhouse gas contributions across different sub-sectors
• Assessing the reliability of emission estimates using the provided confidence scores

Strengths

• Includes monthly source-level granularity since 2021
• Provides confidence scores for emission estimates
• Covers both greenhouse gases and air pollutants

Limitations

• Source ownership data is only included where and when available
• Specific column names and schema are not provided in the source metadata
• Data consists of estimates rather than direct physical measurements
