Definitions In this Act: (1) Carbon score The term carbon score means the projected net greenhouse gas emissions that would result— (A) from the enactment and implementation of a bill or resolution; and (B) if the amounts authorized to be appropriated, or otherwise made available, in the bill or resolution were fully appropriated. (2) Director The term Director means the Director of the Congressional Budget Office. (3) Greenhouse gas The term greenhouse gas has the meaning given the term in section 211(o)(1) of the Clean Air Act ( 42 U.S.C. 7545(o)(1) ).

(b) Net greenhouse gas emissions baseline In calculating the carbon score under subsection (a), the Director shall base any calculation of the increase or decrease of the level of greenhouse gas emissions on a comparison with the level of greenhouse gas emissions occurring under current law. (c) Scope of calculated emissions In calculating the carbon score under subsection (a), the Director shall consider all likely changes in net greenhouse gas emissions, including— (1) any changes to net greenhouse gas emissions that would directly result from activities required to carry out the bill or resolution; and (2) any changes to net greenhouse gas emissions that would— (A) indirectly result from activities required to carry out the bill or resolution
