Marshall Islands Greenhouse Gas Emissions: Monthly Source-Level Data Since 2021

Climate TRACE provides greenhouse gas and air pollutant emission estimates for the Marshall Islands, featuring annual country-level data since 2015 and monthly source-level data since 2021. The inventory covers specific sub-sectors and gas types, derived from a global model of over 2.7 million emission sources. This dataset was produced by the Climate TRACE coalition and was last updated in March 2026.

Use Cases

• Analyzing temporal emission trends in the Marshall Islands using monthly source-level data
• Comparing the environmental impact of different sub-sectors based on gas type breakdowns
• Evaluating the reliability of modeled emissions using the provided confidence scores

Strengths

• Provides monthly granularity for source-level emissions starting in 2021
• Includes confidence scores for monthly source-level estimates
• Covers both greenhouse gases and specific air pollutants across multiple sub-sectors

Limitations

• Data consists of estimates rather than direct sensor measurements
• Source ownership data is inconsistent across the inventory
• Specific column headers and row counts are not explicitly defined in the metadata
