2026 VOTER GUIDE
Election Day is Tuesday, Nov. 3.
Colorado’s 2026 general election will shape our environmental future for years to come. From protecting our lands and water to investing in communities and public transit, your choices at the ballot box this year will have a lasting impact on the state.
In addition to choosing candidates, Colorado voters have the power to decide which ballot measures will change state law or amend the Colorado Constitution. The 2026 ballot includes a particularly long list of measures that can be difficult to understand. And a network of far-right interests has spent millions to get harmful measures on the ballot this year, using messages that intentionally mislead voters about their impacts.
As the state’s largest environmental advocacy organization, we’ve created this guide to help you understand Conservation Colorado’s position on the measures that matter most for Colorado’s climate, air, land, water and communities — and which measures could undermine our hard-earned progress.
Every vote matters when it comes to Colorado’s future.
Ballot Measures
Priority Ballot Measures
Amendment 82: Constitutional Right to Purchase and Sell Natural Gas
Amendment 82 would change the Colorado Constitution to establish a “right” for consumers to buy natural gas for cooking and heating and a right for utilities to sell it. We oppose this intentionally misleading measure that would permanently lock profits for corporate polluters into our state constitution, a radical and permanent change that could overturn essential health and safety protections.
Proposition 137: Direct Sporting Goods Sales Tax Revenue for Conservation
Proposition 137 would allow Colorado to keep and spend sales tax revenue from sporting goods on wildfire mitigation and conservation programs. We support investments that help protect Colorado’s land, water, forests, wildlife and communities.
Ballot Issue 7A: Front Range Passenger Rail District
This issue will only appear on ballots in the proposed service area: Ballot Issue 7A would create a new funding source to help expand the Colorado Connector passenger rail service along the Front Range, from Fort Collins to Pueblo. We support an accessible transit system that gives Coloradans more ways to get where they need to go, reduces pollution from driving and connects communities to jobs, housing and other opportunities.
Other Key Ballot Measures
Amendment 81
Law Enforcement Communication with Federal Immigration Authorities
Amendment 81 would overturn existing state law and require state and local law enforcement agencies to report individuals to federal immigration authorities based solely on assumptions of their immigration status. We oppose this rollback that undermines trust between communities and law enforcement, codifies racial profiling in the state constitution and puts immigrant families at greater risk.
Amendment 84
Mail Ballot Voter Identification
Amendment 84 would add new identification requirements for Colorado voters who cast ballots by mail. We oppose adding unnecessary barriers that could not only expose voters to identity theft but also make it harder for eligible Coloradans to participate in our elections.
Amendment 87
Graduated Income Tax
Amendment 87 would create a tiered income tax system that cuts taxes for 97% of Coloradans while asking the top 3% and large corporations to pay their fair share, generating additional revenue for the state. We support a more equitable tax system that gives Colorado the resources to invest in communities, public services and a healthy environment.
Proposition NN
Keep and Spend Money for Education and Other Purposes
Proposition NN would allow Colorado to keep and spend state revenue on K-12 education and children’s programs. We support investments that strengthen Colorado communities and give Colorado the resources to invest in communities, public services and a healthy environment.
Proposition 134
Male and Female Participation in School and Collegiate Sports
Proposition 134 would require K-12 schools, colleges and universities to restrict sports team participation based on biological sex, taking decisions away from students, parents, schools and athletic experts. We stand with our LGBTQIA+ allies in opposing this measure that puts students through unnecessary scrutiny or invasive processes to participate in school sports.
Proposition 135
Prohibit Surgery on Minors in Response to Perception of Sex or Gender
Proposition 135 would prohibit certain surgeries for people under 18 and restrict public funding and insurance coverage for those procedures. We stand with our LGBTQIA+ allies in opposing policies that take healthcare decisions out of the hands of patients, parents and doctors, and that interfere with medically necessary care.
Proposition 136
Income Tax Rate Limit
Proposition 136 would permanently cap Colorado’s income tax rates at 4.4% for people and big corporations, limiting the state’s ability to generate revenue in the future. We oppose locking Colorado into an inequitable tax structure that prioritizes benefits for billionaires and corporate polluters, and that could limit investments in our climate, communities, infrastructure and public services.
