        of a taxpayer's investment in a greenhouse gas intensity 
        reduction project approved by the accreditation panel, the 
        greenhouse gas intensity reduction investment credit determined 
        under this section for the taxable year is an amount equal to--
                    ``(A) percentage reduction in greenhouse gas 
                intensity certified for such project for such year by 
                the accreditation panel, multiplied by
                    ``(B) the investment in such project during such 
                year which is attributable, directly or indirectly, to 
                the taxpayer, as determined by the accreditation panel.
            ``(2) Aggregate dollar limitation.--The credit determined 
        under paragraph (1) for any taxable year, when added to any 
        credit allowed to the taxpayer with respect to the such project 
        in any preceding taxable year, shall not exceed 50 percent of 
        the investment attributable to the taxpayer with respect to 
        such project through such taxable year.
    ``(b) Limitation on Aggregate Credit Allowable.--
            ``(1) In general.--The amount of the greenhouse gas 
        intensity reduction investment credit determined under 
        subsection (a) for any project, when added to all such credits 
        allowed to all taxpayers with respect to the such project shall 
        not exceed the credit dollar amount allocated to such project 
        under this subsection by the accreditation panel from the 
        greenhouse gas intensity reduction investment credit limitation 
        for the calendar year in which such allocation is made.
            ``(2) Time for making allocation.--An allocation shall be 
        taken into account under paragraph (1) only if it is made not 
        later than the close of the calendar year in which the 
        greenhouse gas intensity reduction project proposal with 
        respect to such project is approved by the accreditation panel.
            ``(3) Overall limitation on aggregate credit allowable.--
        The accreditation panel may allocate the aggregate credit 
        dollar amount to any such project for a period not to exceed a

        paragraph (2).
    ``(c) Limitation on Amount of Credits Allocated.--
            ``(1) In general.--There is a greenhouse gas intensity

                thereafter.
            ``(2) Carryover of unused issuance limitation.--If for any 
        calendar year the limitation amount imposed by paragraph (1) 
        exceeds the amount of greenhouse gas intensity reduction 
        investment credits allocated during such year, such excess 
        shall be carried forward to the succeeding calendar year as an 
        addition to the limitation imposed by paragraph (1).

        approval shall be based on the following criteria:
                    ``(A) The extent of the reduction in greenhouse gas 
                intensity proposed for the project.

        intensity for any period is equal to the volume of emissions 
        divided by the economic output associated with a project as 
        compared to a greenhouse gas intensity baseline established 
        after the date of the enactment of this section. The comparison 
        to such baseline may be made by geographic regions, industry 
        segments, or on a taxpayer basis.

        means a panel jointly certified by the Secretary and the

        period of a greenhouse gas intensity reduction project, there 
        is a recapture event with respect to such project, then the tax 
        imposed by this chapter for the taxable year in which such 
        event occurs shall be increased by the credit recapture amount.

        (1)--

                investment in such project that is attributable to such 
                taxpayer.
                    ``(B) Recapture percentage.--The recapture 
                percentage shall be 100 percent if the recapture event 
                occurs during the first 5 years of the project, 75 
                percent if the recapture event occurs during the second 
                5 years of the project, 50 percent if the recapture 
                event occurs during the third 5 years of the project,

                the approval of the project by the accreditation panel 
                at any time,

                accreditation panel has specified in its approval of 
                the project as a practice which would tend to defeat 
                the purposes of the program, or

                that such disposition will not have any adverse effect 
                on the greenhouse gas intensity reduction project.
        If an event which otherwise would be a recapture event is 
        outside the control of the taxpayer, as determined by the 
        accreditation panel, such event shall not be treated as a

                year shall be increased under paragraph (1) only with 
                respect to credits allowed by reason of this section 
                which were used to reduce tax liability. In the case of
