110TH CONGRESS 

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 decomposition 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 campus, chemists F. Sherwood Rowland and Mario Molina 

began researching the depletion of stratospheric ozone by 

the chlorofluorocarbon gases then used worldwide as refrigerants 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 for 


hsrobinson on PROD1PC76 with BILLS

•HRES 593 IH 

Chlorofluoromethanes: Chlorine Atom-Catalysed Destruction of Ozone’’; 

Whereas in 1976, the work of F. Sherwood Rowland and 

Mario Molina connecting chlorofluorocarbons and atmospheric 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 atmosphere have decreased; 

Whereas on September 17, 1987, the Montreal Protocol was 

open for signatures;

•HRES 593 IH 

Whereas to date, 191 nations have signed the Montreal Protocol; 

Whereas F. Sherwood Rowland, Mario Molina, and Paul 

Crutzen were awarded the Nobel Prize for Chemistry in 

1995 for their work in atmospheric chemistry, particularly concerning the formation and decomposition of 

ozone; and 

Whereas September 17, 2007, marks the twentieth anniversary of the signing of the Montreal Protocol: Now, therefore, be it 

1 Resolved, That the House of Representatives— 

2 (1) congratulates scientists F. Sherwood Row3 land, Mario Molina, and Paul Crutzen for their work 

4 in atmospheric chemistry, particularly concerning 

5 the formation and decomposition of ozone, that led 

6 to the development of the Montreal Protocol on Sub7 stances that Deplete the Ozone Layer; and 

8 (2) encourages the continued research of the 

9 interaction of humans and their actions with the 

10 Earth’s ecosystem.
