CEDA by Watershed
Global scope 3 emissions data for driving climate action
Get the most comprehensive and up-to-date scope 3 carbon emissions data with Watershed’s Comprehensive Environmental Data Archive (CEDA).
The most comprehensive and up-to-date emissions database
CEDA includes 60,000 emissions factors from 400 industries across 148 countries and regions, covering 95% of the world’s GDP. As a multi-regional environmentally extended input-output (EEIO) database, CEDA is unique—providing annually updated data that reflects global decarbonisation in your footprint so you can measure and report with confidence.
Built for companies with global supply chains
CEDA’s emissions factors reflect the complexity of global production and trade—accounting for the significant variance in energy systems and emissions profiles between regions. Single-region models can’t do this, leading to incomplete and inaccurate emissions calculations.
Current, real-world data
While other databases use decade-old information, CEDA’s emissions factors are updated annually. This makes CEDA the most up-to-date spend-based emissions database—reflecting global decarbonisation progress made through governmental action and technological advancements.
Built for assurance, so you can operate with confidence
CEDA is built to be audit-ready with full calculation transparency and comprehensive explanations. Quickly understand calculations, and share with high levels of trust and confidence. Unlike other databases, CEDA benefits from dedicated enablement and scaled support from the Watershed team.
Solving the carbon data challenge
CEDA was developed by Dr. Sangwon Suh, who has spent more than 20 years building the foundations of global carbon data—as an architect of the GHG Protocol, IPCC author, and founder of VitalMetrics (acquired by Watershed).
