In 1987, the world signed a treaty to phase out ozone-depleting substances (ODSs). This data allows you to explore the UN Environment Programme's country-level data displaying how the phase-out of chemicals with ozone-depleting potential (ODP) has progressed across time and space.
Each substance is weighted by its Ozone Depletion Potential, which is a measure of how destructive one tonne of a given chemical is, indexed to CFC‑11. "ODP tonnes" allow a common basis for comparing different chemicals.
Under the Montreal Protocol, the key agreement phasing out ODSs, Consumption = Production + Imports − Exports. Consumption can be negative when a country exports or destroys more than it makes and imports.
HFCs (Annex F) don't harm ozone but are very potent greenhouse gases, so HFCs tracked in CO₂‑equivalent tonnes.
Each line in the below graph represents the world's reported consumption of one controlled ODS group, scaled to its own peak (= 100%). Hover over the graph to compare ODS consumption over time. Major treaties and related agreements are likewise shown. Click on a given ODS to isolate its trend.
Note: When viewing the above graph in "% of peak" mode, each ODS group is indexed to its own maximum year of consumption, taken as 100%, and subsequent values represent the declining percentage thereafter. This allows multiple ODS with orders-of-magnitude different consumption amounts to be displayed at once in a common graphic. Years where global totals dip below zero (net exports/destruction) are drawn at zero. The most recent reporting year with only partial submissions is excluded from global totals.
Click or tap any of the below cards to see details of its usage trajectory across the world.
Click the play button below to see how country-level consumption for a selected substance group changes over time. Note that the EU reports as a single party, so it only appears as a single bar.
Data note: The bars show reported consumption per country or entity. Negative-consumption years with a net export/destruction display here as zero.
198 parties report under the treaty. Search one to see its consumption record across every reported substance group.
HFCs emerged as a major class of replacement refrigerants, but HFCs are potent greenhouse gases. The 2016 Kigali Amendment pulled HFCs into a similar treaty structure as was done with ODPs. These figures display the rise and current status of HFCs on a global scale.
