ERIC DE PLACE and PAELINA DESTEPHANO -Oregon is on the cusp of a climate protection breakthrough in 2018. The state legislature is weighing the Clean Energy Jobs bill, a remarkable opportunity to join its West Coast neighbors in lowering carbon pollution while raising money to invest in clean energy and transportation. The money raised would also provide assistance for low-income state residents. (Sightlineâ€™s Kristin Eberhard wrote an excellent summary of the legislation.) Nevertheless, Oregonâ€™s climate proposal has garnered backlash from a range of shadowy conservative groups determined to halt the billâ€™s progress. Many of these organizations are linked to anti-tax and anti-union politics, and many seem specifically designed to obscure their backers and operations from public view. Itâ€™s a roguesâ€™ gallery of climate-protection opponents in Oregon, and Sightline takes a hard look at whoâ€™s who in this movement and casts some light into the shadows.
