I think you’re right that the initial paper I sent you was perhaps too theoretical. Attached is a paper more to the point. I hope we’re able to discuss this in DC next week. Best, Amy Amy Larkin Director, Greenpeace Solutions 75 West End Ave., #P31B New York, NY 10023 (646) 522

This report would appear to examine the issue from a more generic standpoint, and doesn’t look at these substances as they are used in actual products (R/Fs, etc...), which is how a proper evaluation would have to be done.

Dea r David and Dave, Yesterday, in a phone call with David Calabrese of AHAM, he mentioned that there is an "energy penalty" for hydrocarbon refrigerators. I'm forwarding some information which clearly disputes this. If any of you have information that contradicts this, I would very much like to review it. I've attached a paper out of the School of Mechanical and Manufacturing Engineering at the University of South Wales, entitled "Why Hydrocarbons Save Energy". Also, please reference the website below: http://www.energy

- plus.org/english/news It outlines the most efficient refrigerators on the European market in 2004 (those labeled A+ and A++). There were 85 A++ models (all hydrocarbon) and 769 of the 781 A+ models were also h ydrocarbon. In addition, my European colleagues have anecdotal reports from the largest manufacturers and retailers who indicate that the introduction of hydrocarbons have given their refrigeration fleets an extra boost in energy efficiency. I hope we're able to review this and any other concerns next week in DC. Best, Amy

- 245fa vs HC blowing agents for refrigerators Dave;Please find the most recent research comparing HFC and HC foam blowing

agents attached. In short;

- annual refrigerator energy use is the largest contributor to the CO2 emissions total

- in identical refrigerators, HFC foam uses 12% less energy than HC foam

- HC has 3% grea ter outgassing from the foam over time

- With outgassing, HFC foam uses 15% less energy than HC over time

- US factory safety regulations for use of flammable gases are significantly more stringent in the US

- Europe has pl aced a high value on direct greenhouse gas emissions

- The limited analysis total CO2 emissions shows the amount of HFC advantage varies based on details of de

- commissioning of the foam Hope this is helpful
