PowerAtlas is an open atlas and dataset of the world's power plants — fuel, capacity, owner, technology and asset-level CO₂ (measured for the US & EU via EPA/EU ETS, modelled elsewhere via Climate TRACE) — built and published by Inzonex Research.
A worldwide power-plant backbone (WRI GPPD + Global Energy Monitor) joined with asset-level emissions, climate and corrosivity layers, so each plant page answers a specific, verifiable question. Among usable asset-level CO₂ records, about 28% are regulator-measured (1,157 US EPA / EU ETS records) and 72% are modelled (3,016 Climate TRACE records). Calculated fuel-factor estimates, emission intensities and ISO 9223 corrosivity are labelled separately.
Plant pages list per-plant capacity (MW), primary fuel, owner, country/region, coordinates and measured-vs-modelled CO₂ where reported. Country and company pages aggregate these into fleet totals, fuel mix and grid carbon intensity. Every value traces to the open sources below — WRI GPPD, Ember / Our World in Data, EPA / EU ETS and Climate TRACE — under CC BY.

The plant backbone comes from WRI GPPD and Global Energy Monitor; emissions are labelled as regulator-measured EPA/EU ETS, modelled Climate TRACE, calculated from fuel factors, or unavailable.
No. In the current usable asset-level CO2 subset, about 28% are regulator-measured and 72% are modelled. Plant pages keep those labels visible.
