From Forbes:

So far, environmentalists are largely opposed to the legislation. Some are going so far as to call the agreement made between Manchin and party leadership over the summer a “dirty deal.” However, this opposition is a bit perplexing. First, according to the R Street Institute, 65% of energy projects with federal permits in process are renewable-energy related. Only 19% are fossil fuel projects, and 16% are electricity transmission projects (which, as noted, can benefit renewables). Similarly, the Mountain Valley pipeline, despite being a fossil fuel project, may end up reducing carbon dioxide emissions on balance, since natural gas is cleaner than coal.
