Climate TRACE: U.S. Greenhouse Gas Emissions from 2.7 Million Sources

Climate TRACE provides greenhouse gas and air pollutant emission estimates for the United States, derived from a global inventory of 2.7 million sources. The data includes annual country-level aggregates starting in 2015 and monthly source-level records beginning in 2021, categorized by sub-sector and gas type.

Use Cases

• Tracking annual trends in specific greenhouse gas types across different industrial sub-sectors
• Correlating monthly source-level emissions with local air quality using the 2021-present time series
• Filtering emission sources by confidence scores to prioritize high-certainty data for policy modeling

Strengths

• Covers over 2.7 million emission sources globally with specific U.S. focus
• Provides monthly temporal resolution for source-level data starting in 2021
• Includes confidence scores for modeled emission estimates
• Categorizes emissions by both sub-sector and specific gas type

Limitations

• Emissions are modeled estimates rather than direct sensor measurements
• Source ownership data is incomplete across the full asset list
• Specific column headers and schema are not defined in the source metadata
