'Report card' on Walz's climate performance gives him low marks A coalition led by the Sierra Club North Star Chapter of environmental advocates and native leaders say Gov. Walz is falling short on climate policies. 6:09 pm, Apr. 15, 2021 × Minnesota Governor Tim Walz. State of Minnesota photo. Environmental leaders and organizations say Gov. Tim Walz isn’t doing enough for Minnesota’s climate. The North Star Chapter of the Sierra Club, along with other environmental organizations, issued a mid-term “report card” on Walz’s climate policies. The report was critical of Walz’s proposed budgets on transit, and inaction on blocking Enbridge’s Line 3 project that will transport oil from Canada through Minnesota. The line, which would cross 200 bodies of water, including lakes, wetlands and rivers, and Native American tribal land where wild rice is grown, has sparked ongoing protests.
