Washington Gov. Jay Inslee is expected to sign cap-and-trade legislation to limit climate change that passed both chambers of the state legislature over the weekend. Washington is just the second state to adopt such an extensive climate change policy. The bill will cap climate pollution by sector and businesses that emit less than their allotted amount would be able to sell credits to other businesses. The pool of available credits will shrink in order to achieve net zero emissions by 2050. Funds raised by the cap-and-trade system will fund projects to reduce transportation pollution and improve resilience to climate impacts. The bill will take effect in 2023, unless the Legislature fails to pass a new statewide transportation-spending package by then. (Seattle Times)
