| Action Taken
The Montreal Protocol, which sets reduction rates for HCFCs and other ozone depleting substances, was signed in 1987. |
|
| Hole Discovered
In 1985, a hole in the ozone layer was discovered over Antarctica. |
|
| Refrigerant Debut
DuPont introduced HFC-134a as a CFC in the ‘70s. |
|

|
| New Players
The Environmental Protection Agency (EPA) was established in 1970. |
|
| Dropping Prices
In 1969, the price of R-12 dropped to 0.23 cents per pound. |
|
| Introductions Made
Freon 13 was introduced for temperature refrigeration at –100°F (-73.33°C) and lower in the 1960s. It was intended for use with R-13 or R-22 in a cascade system. |
|
| Growing Popularity
In 1964 home cooling begins to boom and the Air Conditioned World’s Fair opened in New York. |

|
| Numbers Up
In the 1950s, DuPont released its registered refrigerant numbering system for general use to avoid confusion and proliferation of different names for similar products. |
|
| Next Steps
R-13 was developed and released in 1945. |
|
| Expanded Usage
Throughout the 1940’s, companies began using fluorocarbons for refrigeration transport, frozen food production, and medical applications, including frozen blood plasma. |
|
| Employing Freon
In 1933, Westinghouse a/c units begin using F-12 (Freon). |
|
| Growing Trend
Air conditioning begins to expand to restaurants, drug stores, and large retail stores. The first window air conditioner is introduced in 1932 but is not mass produced. |
