Open CEDA: Global Supply-Chain Greenhouse Gas Emissions Model

Open CEDA is a multi-regional Environmentally-Extended Input-Output (EEIO) model developed by Watershed Technology. It connects economic exchanges to greenhouse gas emissions, representing 95% of the world's GDP across 148 countries and 400 sectors. The registry contains CEDA 2025, which uses 2023 as its base year, and CEDA 2024.

Use Cases

• Calculate corporate Scope 3 greenhouse gas emissions based on the integrated input-output and emissions data.
• Perform sustainable spend analysis by quantifying the life-cycle emissions of products and services.
• Conduct environmental systems analyses of global supply chains based on the model's sector and country granularity.

Strengths

• Covers 95% of global GDP across 148 countries.
• Provides granularity with data for 400 economic sectors.
• Updated annually; CEDA 2025 uses 2023 as its base year.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
