If, during an offset project's crediting period, any new law, regulation, or other legally binding mandate requiring GHG emission reductions or GHG removal enhancements goes into effect in Washington, in a linked jurisdiction, or in another jurisdiction in which the offset project is located, during an offset project's crediting period, then the offset project is eligible to continue to receive offset credits for those GHG emission reductions and GHG removal enhancements for the remainder of the offset project's crediting period, but the offset project may not renew that crediting period. If an offset project has not been listed under a compliance offset protocol prior to the effective date of the new law, regulation, or other legally binding mandate, or if the new law, regulation, or other legally binding mandate goes into effect before the offset project's crediting period renews, then only those GHG emission reductions or GHG removal enhancements that are in excess of what is required to comply with the new law, regulation, and/or other legally binding mandate are eligible for offset credits.
