Climate 411

After Colorado legislators passed landmark climate legislation in 2019, which included a statutory mandate directing the Air Quality Control Commission (AQCC) to adopt rules and regulations to reduce statewide emissions, the state has yet to even propose a policy framework capable of getting the job done. This three-part series explores the impact of Colorado’s delay, analyzing the impact on total emissions and the state’s ability to meet its own climate targets.

This year started with promising climate news in Colorado: The state’s largest electric utility, Xcel Energy, announced it will close two of its coal-fired units sooner than planned and support plant workers through retraining and retirement opportunities. While this is a step in the right direction for Colorado’s clean energy future, much more policy action will be needed to meet the state’s statutory emissions goals.

In Part 1 of this series, EDF analysis uncovered the cumulative impact of the Colorado Air Quality Control Commission’s (AQCC) inaction on greenhouse gas emission reductions. Delays will have profound consequences for the total pollution that the state emits over the next decade, which could mean more severe long-term climate damages for Colorado communities and ecosystems. The AQCC’s refusal to seriously evaluate policy mechanisms for much faster and deeper reductions flies in the face of what Colorado legislators mandated in 2019. They set a clear timeline for the AQCC to swiftly propose regulations and reduce statewide emissions 26% by 2025, 50% by 2030 and 90% by 2050, all relative to 2005 emissions.

In Part 2 of this series, we dive into a recent EDF report and analyses released by both the state and other researchers that reveal how Colorado is far off track from achieving these upcoming 2025 and 2030 statutory targets under current policies. The state’s glaring ‘emissions gaps’ underscore the need for transformative leadership on a policy framework capable of securing the reductions consistent with its goals — and protecting Coloradans for generations to come.

After Colorado legislators passed landmark climate legislation in 2019, which included a statutory mandate directing the Air Quality Control Commission (AQCC) to adopt rules and regulations to reduce statewide emissions, the state has yet to adopt a policy framework capable of getting the job done. This three-part series explores the impact of Colorado’s delay, analyzing the impact on total emissions and the state’s ability to meet its own climate targets.

Editor’s note: This post was last updated Feb. 15, 2021 to correct Colorado’s target emissions from gross to net emissions, consistent with data used throughout this analysis. It was also updated Feb. 2, 2021 to reflect Xcel Energy’s announcement to retire two units of the Hayden coal-burning power plant in 2027 and 2028.  Comanche coal power plant in Pueblo, Colorado.

When it comes to reducing greenhouse gas emissions, Colorado—like many other states with leading science-based climate commitments—has a disconnect between rhetoric and reality. Colorado is far from where it needs to be to meet its climate goals, and state regulators just recently slammed on the brakes on a small but important step forward.

After initially voting to accelerate three coal plant retirements as part of a Regional Haze rulemaking in November, state Air Quality Control Commissioners reversed their decision under pressure from the Polis administration to revert back to the later coal plant retirement dates volunteered by industry.

Yet new analyses from EDF, and those released by both the state and other researchers, underscore that Colorado can’t afford a cavalier approach to curbing climate-warming pollution. The state is still far from having a policy framework in place capable of cutting greenhouse gas emissions at the pace and scale required—and Colorado’s first emissions target is right around the corner in 2025.

EDF’s analysis on the impact that these delays will have on total emissions this decade—which will translate into long-term climate damages—underscores why Colorado urgently needs a policy framework that will deliver the ambitious emission reductions that science—and state law—demand.
