Require legislative approval of greenhouse gas rules

HB 630 requires that certain rules established by state departments, commissions, boards, or local authorities are not effective unless approved by the legislature. Specifically, any rules related to the regulation of greenhouse gas emissions or the calculation and application of the social cost of carbon must receive legislative approval at the next legislative session. This mechanism affects agencies that issue such environmental regulations, including those pertaining to the operation of motor vehicles. The bill ensures that the legislature has final say over these specific types of administrative rules.
