HCFCs The Proven Solution
Hydrochlorofluorocarbons (HCFCs) are enabling the phaseout of CFCs. They are energy-efficient, low-in-toxicity, cost effective and can be used safely. Governments and industry
support their global use in applications which meet important environmental and societal needs.
The Parties should continue to support availability and acceptability of HCFCs.
HCFCs are Required for Developing Country CFC Phaseout
Developed countries have had these alternatives, and their corresponding technologies, available
for over a decade. During that period, CFC consumption world-wide has fallen by 75% largely
due to HCFC use. Yet, developing countries continue to increase their CFC consumption. The
Scientific Assessment Report shows that this growth is the most significant ozone depletion issue
facing the Parties. Substitution becomes critical. HCFCs play a significant role in that transition.
As provided in the Montreal Protocol, developed countries have led the transition, and today
total ozone depletion contributions are at their lowest levels since the Parties began discussions.
The following chart shows that ozone depletion potential (ODP) weighted fluorocarbon
production by the Alternative Fluorocarbons Environmental Acceptability Study (AFEAS)
companies is 90% below peak values in 1988.

HCFCs Have Little Ozone Depletion Potential, Short Atmospheric
Lifetimes and Therefore Minimal Environmental Impact
HCFCs are up to 98% less ozone depleting and have 80% shorter atmospheric lifetimes, than
the corresponding CFCs they replaced.
HCFC Contribution to Stratospheric Chlorine is Extremely Small
The chart below shows total chlorine loading assuming full production of CFCs and HCFCs
allowed under the Montreal Protocol and full compliance by all Parties.
| The Scientific Assessment Report stated "if emissions of HCFCs were ... totally eliminated by
2004, future chlo rine loading is predicted to be 5% less over the next 50 years." In contrast, a
modest 20% increase in CFC production by Article 5 (1) countries "is predicted to be a 9%
loading increase." Clearly an HCFC accelerated phaseout or consumption cap reduction
undermines the CFC phaseout and is detrimental to society without significant environmental
benefit. |

In Addition to Environmental Acceptability, CFC Alternatives
Must Be Functional, Economical and Available; HCFCs Meet These Criteria
Alternatives must meet the technology, safety, toxicology and handling requirements, i.e.
functionality, for a given application. Substitutes must be affordable by application, inclusive of
the capital costs. This affordability is most frequently determined by the market. Some
alternatives are not commercially available or cannot be made available in all areas. Industry will
accept only those alternatives which are competitive in the marketplace and are readily available.
The economic viability of an alternative will ultimately determine the fate or acceptability of all
substitutes. Widespread acceptance of HCFCs already signifies their applicability to many
different markets. They are critical to the transition from CFCs for all Parties.
