Calgary's Climate Program

Calgary's Climate Change Program

How is The City addressing climate change?

Climate change is already affecting Calgary. In recent years, we’ve experienced record‑breaking events, including extreme weather like hail and floods.

The City is taking action to manage these impacts and prepare for the future, helping to keep Calgary safe, affordable and resilient.

Calgary’s Climate Strategy – Pathways to 2050, approved in 2022 and shaped by Council, City Administration and the public, is our roadmap to a clean energy, climate-resilient city. It focuses on five priorities:

  • Strong governance foundations
  • Accelerating retrofits and protecting infrastructure
  • Scaling clean energy and technology
  • Enhancing nature-based solutions
  • Strengthening community preparedness, especially for those most at risk

Together, these priorities guide how we reduce emissions, protect the environment and support innovation to reduce risks to people, infrastructure and natural systems.

A coordinated approach across The City

The Environmental Risk and Resilience (ER&R) team leads The City’s climate and environmental work, helping identify risks, meet regulations and support programs across the organization.

ER&R brings together five areas:

  • Natural Environment & Adaptation
  • Energy Management
  • Environmental Management
  • Governance, Reporting & Assurance
  • Utility & Watershed Relations

Together, these teams:

  • Plan and deliver city-wide climate programs
  • Reduce risks from hazards like floods, drought and hail
  • Improve energy use, lower costs and reduce greenhouse gas emissions
  • Work with regional partners to manage water and watershed risks

Working with builders, businesses, developers and community partners

The City’s climate and environmental programs are designed to support decision-making, reduce risks and identify opportunities that benefit Calgary over the long term. Most of this work is non-statutory, meaning it is not required by provincial legislation.

Through research, planning, partnerships and programs, The City works with builders, businesses, developers and community partners to help address climate-related risks and support economic growth.

This approach helps:

  • Improve information available for planning and investment decisions
  • Support innovation and the adoption of new technologies
  • Reduce risks from hazards such as flooding, drought, hail and other extreme weather
  • Identify opportunities to improve efficiency and lower operating costs
  • Help Calgary remain competitive, resilient and attractive for investment

The City’s role is to provide guidance, programs, information and coordination that support community and industry efforts while working within existing regulatory frameworks.

Why this work matters

Climate change affects everyday life in Calgary, impacting essential services like drinking water, parks, roads, recreation and emergency response.

Because Calgary’s infrastructure wasn’t built for today’s changing climate, events like floods, drought and extreme heat are increasing costs and putting pressure on infrastructure systems, while also affecting health, safety and the economy.

Taking action helps The City plan ahead and reduce long-term costs by:

  • Avoiding costly damage and repairs
  • Lowering operating and energy expenses
  • Leveraging external funding

This work also supports economic growth by encouraging innovation, clean technology and local job creation, while helping build a safer, healthier and more livable city.

Supporting strong, reliable services

Through its Climate Strategy and ongoing programs, The City continues to guide investments and actions that support a safe, reliable and thriving community.

Tracking progress

Frequently asked questions (FAQs)

How does Calgary contribute to climate change?

In Calgary, we track the amount of greenhouse gas emissions added to the atmosphere every year through activities that happen within our city boundaries.

99 per cent of Calgary's greenhouse gas emissions come from transportation and the heating, lighting and power demands in buildings. The remaining one per cent of emissions in Calgary come from methane from our landfills.

City of Calgary operations (our buildings and facilities, our fleet, our landfills) represent four per cent of the total emissions in Calgary. The remaining 96 per cent comes from the residential, commercial, industrial and institutional sectors in Calgary.

 Community-wise energy use by fuel type


Natural Gas - 33%
Diesel - 16%
Electricity - 24%
Gasoline - 26%
Waste - 1%

Community-wise GHG emissions by source


Transportation - 42.5%
Buildings - 56.5%
Waste -1%

What does climate change mean for Calgary?

Alberta has experienced significant changes to its climate in recent decades. Average annual temperatures in Alberta are expected to continue to increase.

Climate modelling tells us Calgary will experience more severe and frequent extreme weather events such as heat waves, drought and severe storms. A detailed analysis of the climate modelling results is provided within the *Climate Projections for Calgary Report.

*The science of climate modelling continues to evolve and every few years a new generation of climate projections are released. We are currently in the process of updating our climate projections to the most recent modelling available; however, this update will not be complete until 2027. Calgary’s current Climate Projections rely on RCP8.5 emissions scenario; the continued use of RCP8.5 remains acceptable for ongoing or legacy work until The City’s climate projections are updated.

What are the Climate hazards in Calgary?

Climate change hazards pose risks to the health and wellness of Calgarians, the economy, public infrastructure and services, homes and private property, and natural ecosystems.

Eight climate hazards are becoming more likely in Calgary and/or severe due to climate change.

Long description

Extreme heat: Calgary will experience increasingly hot summers with more frequent and longer heat waves.

Drought: Drought conditions may become more common, prolonged and widespread.

Wildfire smoke: A longer and drier fire season will lead to more frequent, larger, and intense wildfires, which leads to more frequent and severe wildfire smoke in Calgary

Shifting seasons: Winters are getting shorter, spring is arriving earlier, summers are longer and fall is arriving later.

Heavy rainfall: More precipitation is falling as short-duration, high-intensity storms (SDHI) which can lead to overland flooding.

Heavy snowfall: Damaging winter storms, heavy snow and blizzard conditions will continue to be hazards as core winter months remain below 0℃.

Severe storms: Hail, high wind events and tornadoes are likelyto occur more frequently and over more months of the year.

River flooding: Flood timing, intensity and frequency is likely increasing.

How does The City's climate work affect builders and developers?
