Data Sources & Methodology

      
Transparent, reproducible, open.

    

    

      

        

        
ENTSO-E Transparency Platform

        
Real-time generation data per fuel type from the official European electricity transmission operator platform.

      

      

        

        
IPCC AR6 Emission Factors

        
Lifecycle median gCO₂eq/kWh per fuel type from the Intergovernmental Panel on Climate Change, 6th Assessment Report.

      

      

        
Σ

        
Weighted Average

        
Intensity = Σ (generation share × emission factor). Location-based method following GHG Protocol Scope 2 Guidance.

      

    

  






  

    

      
Why This Exists

      
The EU's electricity grids publish generation data through ENTSO-E, but the raw data is painful: inconsistent XML formats, frequent gaps, rate limits, and no pre-computed emissions intensities. Every developer building carbon-aware tools ends up writing the same parsing and gap-filling code.

      
This API does that work once so you don't have to. It normalises ENTSO-E generation data, applies IPCC AR6 lifecycle emission factors, and serves clean, hourly gCO₂eq/kWh — ready for Scope 2 reporting, carbon-aware scheduling, demand response, or any application that needs to know how dirty the grid is right now.
