State Crossover Adjourn Rollover Prospect Details
Alabama N/A 15 May 2025 Extremely low chance It has languished in its initial House committee since 11 February, with no hearings or votes. Adjournment looms on 15 May—about two weeks and only a few meeting days away—and Alabama seldom moves first-committee bills this late.
Arizona N/A 9 May 2025 Very low chance Although both bills have cleared their chamber of origin, they await first action in the opposite house. All committee deadlines (April 19) have passed, leaving rule suspension as the only path. With adjournment fixed for May 9, Arizona rarely advances fresh policy bills this late, so passage this year is highly improbable.
Connecticut N/A 4 Jun 2025 Effectively dead Still sitting in the Environment Committee since its referral on January 8, with no hearing or vote. The committee’s joint-favourable deadlines passed in late March, and bills that miss those cut-offs die before the constitutional adjournment on June 4, 2025.
Florida N/A 2 May 2025 Near-certain The House passed CS/CS/SB 56 on 30 Apr 2025 (82-28) without amendment and ordered it enrolled; HB 477 was laid on the table in its favour the same day. Governor DeSantis publicly urged support for the bill in an X (Twitter) video on 2 Apr 2025, and no substantive objections have surfaced since. Only a veto could stop enactment, and a veto is unlikely given the Governor’s recorded endorsement and the wide bipartisan margins.
Georgia 6 Mar 2025 2 Apr 2025 Resume 2026 Limited potential to progress Introduced after the 2025 crossover deadline (Day 29, 10 Mar) and left idle in House Natural Resources & Environment; though Georgia’s two-year biennium carries bills into 2026, measures that miss crossover seldom advance without high-profile backing, so revival next session appears unlikely.
Illinois 11 Apr 2025 31 May 2025 Resume 2026 Very unlikely to proceed The bill missed the Senate third-reading deadline of April 11 and has sat in Senate Assignments since filing on January 31. When revived in 2026, it must clear the committee and repeat the whole process within tighter spring deadlines, a feat seldom achieved by carry-over bills.
Iowa N/A 2 May 2025 Yes Extremely low chance HF 927 and SF 142 failed to clear their respective committees before the April 4 second-funnel deadline, a cut-off that renders most bills ineligible for floor debate. When carried over into 2026, they must restart the committee process and meet compressed Year-2 funnels, a hurdle rarely overcome by controversial measures.
Louisiana 9 Jun 2025 12 Jun 2025 Moderately high chance SB 46 passed the Senate on 28 Apr 2025 (27–12) and has been in the House Natural Resources & Environment Committee since 29 Apr 2025. Florida’s SB 56—an almost identical prohibition—cleared its House 82–28 on 30 Apr 2025 and is now enrolled, giving supporters in Baton Rouge a successful playbook and momentum. Procedurally, SB 46 still needs one committee hearing, House floor passage, and possible concurrence, but the House has six weeks of meeting days to accomplish that. Governor Landry has not commented publicly; however, the measure is framed as an environmental-safety bill rather than a climate mandate, which aligns with his stated priorities. Because leadership can compress readings late in session (as Florida just did), chances improve from moderate to moderately high. Failure to reach the House floor before 12 June would still kill the bill for 2025 and require refiling in 2026.
Maine N/A 21 Mar 2025 Very low chance On 30 Apr 2025 the Senate concurred in the House Ought Not to Pass action on LD 499, placing it in the legislative files and ending that bill for the biennium. The only remaining vehicle is LD 825, which was carried over on 21 Mar 2025 after receiving a divided report in committee. Carry-over measures start 2026 with no further committee work completed, and historically fewer than one in five succeed in Maine’s short second session. With LD 825 lacking demonstrated chamber support and its twin already rejected, ultimate passage next year remains highly improbable.
Michigan N/A 31 Dec 2025 Yes Low chance overall Introduced 26 Mar 2025 and parked in House Regulatory Reform with no hearing set. Although Michigan’s constitution carries all odd-year bills into the 2026 session, measures that enter the summer still in the first committee seldom gain traction, so enactment appears doubtful.
Minnesota N/A 19 May 2025 Yes Extremely low chance Since their introduction in mid-March, HF 2310 and SF 2462 have sat in their initial Environment committees. They missed the April 4 first-deadline for committee passage, so further movement this year would require a rare rules waiver before the May 19 adjournment. Carry-over success in 2026 is similarly uncommon.
Missouri N/A 16 May 2025 Very unlikely to proceed SB 297 has been in Senate Agriculture without a hearing since its referral on February 13, 2025, and its House companion HB 78 is still only on second reading. With the General Assembly slated to adjourn on May 16, 2025, moving dormant first-committee bills through both chambers is virtually impossible.
New Hampshire 10 Apr 2025 30 Jun 2025 Resume 2026 Extremely low chance The House placed HB 764 on the table on 13 March 2025 and defeated a motion to remove it the same day. Because the House missed the 10 April crossover cutoff, members can carry the bill into 2026, but tabled bills rarely re-emerge for passage.
New Jersey N/A 31 Dec 2025 Limited potential to progress Introduced 25 Feb 2025 and still parked in the Senate Environment & Energy Committee with a single GOP sponsor. Although the 2024-25 biennium runs until late December, New Jersey bills that linger unheard for months rarely gather the momentum needed to clear both chambers.
New York N/A 12 Jun 2025 Yes Very low chance Still in the Assembly Environmental Conservation Committee since introduction on 14 February 2025. With the 2025 session set to adjourn on 12 Jun 2025, first-house bills that have yet to receive a hearing rarely make it through both chambers; although they can carry into 2026, similar dormant measures seldom advance.
North Carolina 8 May 2025 31 Jul 2025 Yes Very low chance Both measures remain in the House and Senate Rules committees after first-reading referrals in March. They must clear their chamber of origin before the 8 May crossover deadline—an unlikely feat—and carry-over bills rarely revive in the short second session.
Oklahoma 27 Mar 2025 30 May 2025 Resume 2026 Extremely low chance SB 1021 and SB 430 never advanced past referral to Senate Energy and missed the Mar 27 chamber-of-origin deadline. When revived in 2026, they must restart in committee, and Oklahoma’s carry-over measures rarely gain traction after such an inert first year.
Pennsylvania N/A 31 Dec 2025 Yes Limited potential to progress HB 1167 (referred 7 Apr 2025) and SB 508 (referred 21 Mar 2025) remain in their initial committees with single-party sponsorship. Although Pennsylvania’s two-year session runs through 2026, most bills languishing in committee for months never receive a hearing, so ultimate enactment appears doubtful.
Rhode Island N/A 30 Jun 2025 Extremely low chance H 5217 was “held for further study” on 6 February 2025, and S 0405 has not seen action since its referral on 26 February. The House committee-hearing deadline (22 April) has lapsed, and the session ends on 30 June 2025, leaving virtually no pathway for stalled first-hearing bills to advance.
South Carolina N/A 8 May 2025 Yes Extremely low chance All four measures were in their initial committees from January to February. The General Assembly adjourns on 8 May 2025, leaving no time for first-house action. When they carry over into 2026, similar clean-air proposals rarely advance.
Tennessee N/A 22 Apr 2025 Resume 2026 Limited potential to progress HB 1112 cleared the House in March but is still awaiting a Senate committee referral, while HB 899 and SB 723 never advanced past introduction. The legislature recessed on 22 April 2025; when the bills revive in 2026, they must navigate fresh deadlines, and Tennessee carryovers rarely succeed without strong leadership backing.
Texas N/A 2 Jun 2025 Very low chance HB 1382 (referred to Agriculture & Livestock 3 Mar), HB 3740 (to Licensing & Administrative Procedures 26 Mar), and SB 1154 (to Senate Natural Resources 28 Feb) have seen no further movement. House committees must report bills by 12 May, and the 89th Regular Session ends 2 Jun 2025, a window too narrow for first-hearing measures to clear both chambers.
Vermont 14 Mar 2025 9 May 2025 Resume 2026 Very unlikely to proceed H 0217 never left House Environment & Energy and missed the March 14 crossover cut-off. With adjournment set for May 9, 2025, carry-over bills seldom advance in Vermont’s brief 2026 session, so passage is doubtful.
West Virginia 2 Apr 2025 12 Apr 2025 Resume 2026 Extremely low chance HB 2758, HB 3207, and SB 699 stalled in their first committees before the 2 April 2025 crossover cut-off, and the session adjourned on 12 April. When they carry over into 2026, they must restart the process, and West Virginia carryovers rarely pass.
