Low carbon multiplier effect detailed at Yale

Dear Friend,

As Congress prepares to debate new legislation to address the threat of
climate change, opponents again claim that the costs of adopting the
leading proposals would be ruinous to the U.S. economy. The world's leading
economists who have studied the issue say that's wrong. And you can find
out for yourself.

Today, Yale's School of Forestry & Environmental Studies posted a new
website developed by economics professor Robert Repetto. In a way that
anybody can easily understand, it synthesizes the results of thousands of
policy simulations from 25 economic models being used to predict the
economic impacts of reducing U.S. carbon emissions. To try this new
website, just click on

This website identifies the seven key assumptions accounting for most of
the differences in the models' predictions. It shows that even under the
most unfavorable assumptions regarding costs, the U.S. economy is
predicted to continue growing robustly as carbon emissions are reduced.
Under more favorable assumptions, the economy would even grow more rapidly
if emissions are reduced than if they are allowed to continue to increase
as in the past.

Even better, this new website allows site visitors to decide how likely
they think each of the seven key assumptions are, and on that basis see for
themselves what economic impacts all the leading economic models would
predict, if carbon emissions are reduced by specific percentages over the
next two decades. If you visit this site, you can make your own assumptions
about the key factors that will influence the costs of stopping climate
change and see the results.

We urge you to click on and use this new analysis. Tell your associates
and contacts about it and create links to it on your own website.
