Sierra Club Joins NO on 300/301 Coalition

Louisville, Colo. (Oct. 20, 2025) – Louisville Together, a broad-based community coalition of elected officials, affordable housing providers, business leaders, and residents, today announced the Sierra Club’s Indian Peaks Group has formally endorsed voting NO on 300/301. 

An accompanying statement from the organization’s Executive Committee is below:

“The Sierra Club endorses a vote of NO on Ballot Measures 300 and 301. These measures do not support climate resilience, and they will make it prohibitively expensive to build any new housing, including affordable housing.”

With its endorsement, Sierra Club joins a unanimous Louisville City Council, affordable housing providers that include Flatirons Habitat for Humanity and Thistle, and Louisville’s business community in opposing the pair of misleading measures.

“We are grateful for the Sierra Club’s explicit acknowledgement that these two measures are not climate-friendly, and will impede progress on our climate goals,” said Tim Bierman, a leader of Louisville Together. “With this endorsement, we can proudly say that every major environmental, housing, mobility, business, and good governance expert oppose 300/301 – with not a single organization or elected official standing up in support.”
