To the editor — I am writing in response to the Oct. 2 article on the Sierra Club and Initiative 732. Why doesn’t the Sierra Club support this practical, bipartisan, proven approach to reducing carbon pollution? I would direct you to the three-part, unvarnished review of I-732 by the Sightline Institute, The Sightline Institute concludes that I-732 is “a worthy policy to put Washington on a path to cutting pollution and encouraging clean energy while also helping low-income families by making Washington State taxes less regressive.” Vote yes for Initiative 732.
