Global Chemicals Inventory

The Global Chemicals Inventory (GChI) provides information on global production of eight “building block” chemicals: ethylene, propylene, and butadiene (“olefins”); benzene, toluene, and xylene (“aromatics”); ammonia; and methanol. GChI was developed as a joint effort between Global Energy Monitor and the Spatial Finance Initiative. The Spatial Finance Initiative is hosted at the Oxford Sustainable Finance Programme at the University of Oxford.

The GChI includes plant-level data on location, ownership, primary and secondary chemical products, and feedstocks. The GChI comprises facilities that produce any of the eight building block chemicals, including standalone chemical plants, oil refineries, integrated refinery and chemical complexes, and ammonia and methanol production facilities. Each of these plant types consist of multiple units, which vary depending on chemical type and production method. Each plant included in the inventory is linked to a wiki page on GEM.wiki that provides additional details.

The most recent release of this data was in November 2025. GChI only includes plant-level data for chemical plants that are operational as of September 1, 2025. The GChI map and underlying data will be converted to a full Global Chemicals Tracker in the future and updated annually.
