1ST SESSION 
H. RES. 593 
Congratulating scientists F. Sherwood Rowland, Mario Molina, and Paul 
Crutzen for their work in atmospheric chemistry, particularly concerning 
the formation and decomposition of ozone, that led to the development 
of the Montreal Protocol on Substances that Deplete the Ozone Layer. 
IN THE HOUSE OF REPRESENTATIVES 
JULY 31, 2007 
Ms. LORETTA SANCHEZ of California submitted the following resolution; 
which was referred to the Committee on Science and Technology 
RESOLUTION 
Congratulating scientists F. Sherwood Rowland, Mario 
Molina, and Paul Crutzen for their work in atmospheric 
chemistry, particularly concerning the formation and de-
composition of ozone, that led to the development of 
the Montreal Protocol on Substances that Deplete the 
Ozone Layer. 
Whereas in 1973, on the University of California, Irvine cam-
pus, chemists F. Sherwood Rowland and Mario Molina 
began researching the depletion of stratospheric ozone by 
the chlorofluorocarbon gases then used worldwide as re-
frigerants and aerosol propellants; 
Whereas on June 28, 1974, F. Sherwood Rowland and Mario 
Molina published in the scientific journal Nature, their 
path-breaking 
article, 
‘‘Stratospheric 
Sink

Chlorofluoromethanes: Chlorine Atom-Catalysed Destruc-
tion of Ozone’’; 
Whereas in 1976, the work of F. Sherwood Rowland and 
Mario Molina connecting chlorofluorocarbons and atmos-
pheric ozone depletion was confirmed by the National 
Academy of Sciences; 
Whereas 
in 
1978, 
the 
United 
States 
banned 
chlorofluorocarbons as propellants in aerosol cans; 
Whereas in 1987, because of the research of F. Sherwood 
Rowland, Mario Molina, Paul Crutzen, and many other 
scientists, the international community acted through the 
adoption of the Montreal Protocol on Substances that 
Deplete the Ozone Layer (‘‘Montreal Protocol’’); 
Whereas the Montreal Protocol created the Multilateral Fund 
for the Implementation of the Montreal Protocol which 
provides funds to help developing countries to phase out 
the use of ozone-depleting substances; 
Whereas the Multilateral Fund for Implementation of the 
Montreal Protocol was the first financial mechanism to 
be created under an international treaty; 
Whereas the Montreal Protocol recognized that world-wide 
emissions of certain substances can significantly deplete 
and otherwise modify the ozone layer in a manner that 
is likely to result in adverse effects on human health and 
the environment; 
Whereas because of the adoption of the Montreal Protocol the 
levels of chlorofluorocarbon gases in the Earth’s atmos-
phere have decreased; 
Whereas on September 17, 1987, the Montreal Protocol was 
open for signatures;

Whereas to date, 191 nations have signed the Montreal Pro-
tocol; 
Whereas F. Sherwood Rowland, Mario Molina, and Paul 
Crutzen were awarded the Nobel Prize for Chemistry in 
1995 for their work in atmospheric chemistry, particu-
larly concerning the formation and decomposition of 
ozone; and 
Whereas September 17, 2007, marks the twentieth anniver-
sary of the signing of the Montreal Protocol: Now, there-
fore, be it 
Resolved, That the House of Representatives— 
(1) congratulates scientists F. Sherwood Row-
land, Mario Molina, and Paul Crutzen for their work 
in atmospheric chemistry, particularly concerning 
the formation and decomposition of ozone, that led 
to the development of the Montreal Protocol on Sub-
stances that Deplete the Ozone Layer; and 
(2) encourages the continued research of the 
interaction of humans and their actions with the 
Earth’s ecosystem.
