Japan: Greenhouse Gas and Air Pollutant Emissions from 2015

Climate TRACE provides annual and monthly greenhouse gas and air pollutant emission estimates for Japan, featuring country-level data from 2015 and source-level data from 2021. The inventory includes sub-sector and gas-specific breakdowns derived from a global monitoring network of over 2.7 million sources. These estimates are updated to reflect recent activity and include confidence metrics for asset-level records.

Use Cases

• Analyzing sub-sector contributions to Japan's total GHG inventory using annual gas-specific data
• Evaluating industrial facility performance using monthly source-level emission estimates
• Assessing data reliability using the provided confidence scores for asset-level records

Strengths

• Monthly granularity for source-level emissions since 2021
• Includes confidence scores for all monthly source-level estimates
• Provides sub-sector and gas-specific breakdowns for annual country-level data

Limitations

• Emissions are modeled estimates rather than direct sensor measurements
• Ownership data for specific assets is inconsistent and may be missing
• Temporal coverage for source-level data is significantly shorter than country-level data
