Faster, more-effective decarbonization starts with detailed knowledge of emissions sources.
Climate TRACE represents a detailed database of human-caused emissions from all major sources—from power plants and oil refineries to rice cultivation, cement production, and shipping. This emissions inventory is tied to direct observations of emissions sources, and reveals opportunities for meaningful action to mitigate the climate impacts of specific activities.
Sectors
Greenhouse gas emissions from electricity generation.

subsector
Electricity generation Power plant
definition
Greenhouse gas emissions from thermal power plants from all major fuel sources including coal, natural gas, fuel oil, diesel, biomass, and incinerated waste.
source
methodology
Power sector emissions are estimated by first assembling a global geolocated inventory of power plants, generation, and metered emissions data. Machine learning models then predict power plant generation from satellite images. These predictions are aggregated and combined with available generation data and carbon intensity factors to derive emissions estimates.

Relevant emissions factors for the plant are applied to derive the emissions for a given year. Soda ash manufacturing emissions are derived from utilization rates obtained from country level data, split by natural and synthetic soda ash producing countries, and projected to plant level as a proxy for plant level production. Methanol manufacturing emissions are derived from average utilization rates by country projected to the plant level. Where data were unavailable, a relationship between country-level installed capacity and utilization rates was used to fill in gaps.
