Congressional Budget Office Cost Estimate: H.R. 2420, International Climate Cooperation Re-engagement Act of 2007 [open pdf - 62KB]
From the Summary: "H.R. 2420 would authorize the appropriation of funds to develop and promote energy technologies that do not release greenhouse gases into the atmosphere. CBO [Congressional Budget Office] estimates that implementing H.R. 2420 would cost $37 million in 2008 and $772 million over the 2008- 2012 period, assuming appropriation of the specified and estimated amounts. While the bill would allow the International Clean Energy Foundation to receive and spend gifts and donations, CBO estimates that H.R. 2420 would have no significant effect on direct spending and receipts. H.R. 2420 contains no intergovernmental or private-sector mandates as defined in the Unfunded Mandates Reform Act (UMRA) and would not affect the budgets of state, local, or tribal governments."
