About DPS Sustainability


Conserve and manage resources to address environmental impact, social development, and economic prosperity. We are focused on creating a learning environment where sustainability is integral. It is our objective to maintain fiscal responsibility through sustainable practices with the understanding of how the built environment impacts our natural environment.


Denver Public Schools is a leader in sustainability, creating healthy learning and working environments that connect students and staff with the wonder of nature and resource conservation. Our DPS community will have the tools, support, and experience to be stewards of the world and leaders in driving change.

Goals and Frameworks:

Throughout the Climate Action Planning process, the DPS community voiced their support for many priorities, innovative ideas, and actions that informed the resulting goals and strategies in this plan. Three key concepts, which echo the sustainability concept of triple-bottom line, emerged from their feedback and the goals advocated for by DPS Students for Climate Action: environmental protection, economic prosperity, and social development.

Within each concept the DPS team and stakeholders crafted a North Star goal, which represents what DPS aims to achieve by 2050. The North Star goals are broken into six frameworks, each with focus areas, five-year goals, and supporting strategies and actions.

Thank you for your interest in sustainability at DPS!

We heard our student’s call for climate action, and we are responding with urgency, innovation, and accountability. This website provides transparency on our progress toward DPS’ climate actions goals, and it will help us celebrate milestones along the way. We hope that by sharing our story, you’ll join our efforts for a livable future!

We’re Shrinking Our Footprint!

DPS has committed to reducing overall greenhouse gas emissions (GHG) by at least 90% of the levels of GHG emissions that existed in 2010 by 2050.

The chart shows total DPS GHG emissions by sector from fiscal year 2016 through fiscal year 2021. The dashed line indicates the progress needed to reach the 90% reduction goal by 2050.

Climate Resolution Priorities


The DPS Board of Education unanimously passed the agreed upon climate policy, setting the district on a path to develop a comprehensive Climate Action Plan. The plan uses the student’s proposed climate goals from the City of Denver and the State of Colorado as guides and has a strong focus on environmental justice.

Climate Action End Statement 1.6: DPS shall be a national leader in establishing an organizational culture anchored in sustainability, climate action, and environmental justice in both the conservation of natural resources and in minimizing the carbon footprint of DPS’ practices.

He is a proponent of using automation to provide efficiency, reliability, and cost effectiveness for school buildings.

Brian Slota

Building Optimization Specialist

Brian figures out how to make DPS buildings run efficiently and at optimal comfort for occupants. He enjoys tinkering with things that don’t work, fixing them, and repressing expletives when they refuse to cooperate. He remembers receiving a musical book with a hand crank as a child and tearing it apart to see how it worked – much to his parent’s dismay. He has since worked on fixing airplanes, radios, and electronics. Outside of work, Brian can be found skiing, catching trout, or toying with ham radio.
