Denver’s Climate Office Launches 2025 Annual Report

Denver's Climate Office Launches 2025 Annual Report

Published on June 30, 2026

Today, Denver's Office of Climate Action, Sustainability and Resiliency (CASR) released its 2025 Annual Report, highlighting the city's continued success in cutting carbon pollution and protecting neighborhoods from the impacts of climate change.

"At a time when many places are slowing their climate commitments, Denver is choosing to lead," said Mayor Mike Johnston. "We're acting now to build a more vibrant, affordable, and resilient city for everyone. And we're moving with urgency because the impacts of extreme heat, drought, and a changing climate are already here."

The report includes the city's projected greenhouse gas emissions inventory for 2025, along with details of the Climate Protection Fund's community investments. Approved by Denver voters via a sales tax increase in 2020, the fund now generates nearly $50 million annually. The launch of CASR's 2025 Annual Report is accompanied by the debut of a new online tool that Denverites can use to explore Denver's greenhouse gas emission sources and trends.

CASR's Annual Report highlights Denver's key 2025 progress on climate resiliency, including:

• 2,000 clean energy systems-like solar panels, heat pumps, and EV chargers- installed, 4,500 trees planted and 20 million gallons of municipal water usage cut, meeting and exceeding the citywide annual goal.
• 55% of Climate Protection Fund dollars invested in Denver's disproportionately impacted communities.
• 4.5% projected reduction in greenhouse gas emissions over the course of only one year.
• 15% increase in the number of clean energy systems installed through the city's Climate Protection Fund programs.
• 26% more heat pumps and 38% more heat pump water heaters permitted than the year before.
• Three times more all-electric buildings permitted compared to the prior year.
• 830,000 miles of car trips replaced with e-bike trips from Denver's e-bike rebate redeemers.
• 458 Denverites trained or upskilled in clean energy or natural resource management careers.
• 572 air purifiers and 155 air conditioners installed in North and West Denver neighborhoods facing the greatest heat and air-quality burdens.
• 131.1 million impressions made by the groundbreaking "Do More. Do Less. Do Something" campaign, which inspired 1 in every 4 Denverites who recognized the campaign to commit to taking more climate-friendly actions.

2025 marked a major milestone in Denver's road to achieve science-based emissions targets. In 2019, working with urban sustainability experts and guided by international climate science, Denver set a goal to reduce greenhouse gas emissions by 40% from a 2019 baseline by 2025, with the ultimate goal of eliminating emissions by 2040.

From 2019 to 2025, Denver achieved a 20% overall reduction in emissions. Looking at the longer trend, emissions decreased approximately 36% from 2015 to 2025.

"Denver set science-based climate goals because the scale of the challenge demands ambition," said Elizabeth Babcock, Director of Denver's Office of Climate Action, Sustainability and Resiliency. "While we did not meet the 2025 target, our progress is real, measurable and accelerating. Every investment moves us closer to a cleaner, healthier and more resilient Denver, and the progress we saw in 2025 sets the foundation for the years ahead."

CASR will be launching public engagement later this summer to update Denver's Climate Plan, as the previous city climate plan expires in late 2026. Working among agencies and with experts and community members, the city will assess strategies to ensure every neighborhood is powered by clean energy and protected from climate risks. CASR's newsletters and website will publish updates on this process as they are available.
