HCFC Phaseout Schedule
For more information

All developed (i.e., non-Article 5) countries are subject to caps on their consumption and production of hydrochlorofluorocarbons (HCFCs), according to the terms of the Montreal Protocol and its amendments. Under the Montreal Protocol, the U.S. and other developed nations must achieve a certain percentage of progress towards the total phaseout of production and consumption of HCFCs, by certain dates.
Consumption is calculated by the following formula: consumption = production plus imports minus exports. The cap for developed countries is set at 2.8% of that country's 1989 chlorofluorocarbon consumption + 100% of that country's 1989 HCFC consumption. The cap on production is set at the average of a) 1989 HCFC production + 2.8% of 1989 CFC production and b) 1989 HCFC consumption + 2.8% of 1989 CFC consumption. (Quantities of chemicals measured under the cap are ODP-weighted, which means that each chemical's relative contribution to ozone depletion is taken into account.)
At the 19th Meeting of the Parties to the Montreal Protocol in September 2007, the Parties agreed to a more aggressive phasedown of HCFCs in both developing and developed countries. More details about the September 2007 adjustments to the Montreal Protocol are available here (PDF) (4 pp, 38K, About PDF). In addition, a graphical representation of the reductions for developing countries is found here.
The following table shows the U.S. schedule for phasing out its production and consumption of HCFCs in accordance with the terms of the Protocol. The third and fourth columns of the table show how the U.S. is meeting the international obligations described in the first two columns.
| Montreal Protocol | United States | ||
|---|---|---|---|
| Year to be Implemented | % Reduction in Consumption and Production, Using the Cap as a Baseline | Year to be Implemented | Implementation of HCFC Phaseout through Clean Air Act Regulations |
| 2004 | 35.0% | 2003 | No production and no importing of HCFC-141b |
| 2010 | 75.0% | 2010 | In addition to the HCFC-141b restrictions, no production and no importing of HCFC-142b and HCFC-22, except for use in equipment manufactured before 1/1/2010 (so no production or importing for NEW equipment that uses these compounds) |
| 2015 | 90.0% | 2015 | In addition to the HCFC-141b, HCFC-142b and HCFC-22 restrictions, no production and no importing of any other HCFCs, except for use as refrigerants in equipment manufactured before 1/1/2020 |
| 2020 | 99.5% | 2020 | No production and no importing of HCFC-142b and HCFC-22 |
| 2030 | 100.0% | 2030 | No production and no importing of any HCFCs |
