II 119th CONGRESS 1st Session S. 1842 IN THE SENATE OF THE UNITED STATES May 21, 2025 Mr. Whitehouse (for himself and Mr. Schiff ) introduced the following bill; which was read twice and referred to the Committee on Finance A BILL To amend the Internal Revenue Code of 1986 to create a credit for carbon removal and storage for forest residues from wildfire management.

1. Short title This Act may be cited as the Wildfire Reduction and Carbon Removal Act of 2025 . 2. Credit for forest residue carbon removal and storage (a) In general Subpart D of part IV of subchapter A of chapter 1 of the Internal Revenue Code of 1986 is amended by adding at the end the following new section: 45BB. Forest residue carbon removal and storage (a) General rule For purposes of section 38, the forest residue carbon removal and storage credit for any taxable year is an amount equal to the applicable dollar amount per metric ton of qualified carbon dioxide equivalent which is— (1) captured by the taxpayer from qualified forest residue biomass using biomass equipment which was originally placed in service at a qualified forest residue biomass carbon removal and storage project on or after the date of the enactment of the Wildfire Reduction and Carbon Removal Act of 2025 , and (2) stored by the taxpayer in secure geological storage or via long-duration utilization. (b) Applicable dollar amount For purposes of this section— (1) In general The applicable dollar amount is— (A) $36, in the case of qualified carbon dioxide equivalent stored in secure geological storage, and (B) $12, in the case of qualified carbon dioxide equivalent stored via long-duration utilization. (2) Adjustment for inflation In the case of any taxable year beginning in a calendar year after 2026, the $36 and $12 amounts under paragraph (1) shall each be multiplied by the inflation adjustment factor determined under section 43(b)(3)(B) for such calendar year, determined by substituting 2025 for 1990 . (3) Increased credit amount for certain facilities (A) In general In the case of qualified carbon dioxide equivalent which is described in subsection (a)(1) and which meets the requirements of paragraphs (3) and (4) of section 45Q(h) (determined after application of the modifications described in subparagraph (B)), the amount applicable shall be equal to such amount (determined without regard to this paragraph) multiplied by 5. (B) Modifications The modifications described in this subparagraph are as follows: (i) In section 45Q(h)(3)(A), the term qualified forest residue biomass carbon removal and storage project shall be substituted for qualified facility each place it appears, and such project shall be substituted for such facility each place it appears. (ii) In section 45Q(h)(3)(A), the term biomass equipment shall be substituted for carbon capture equipment in the matter before subparagraph (A).
