Calgary's Climate Program

Calgary's Climate Change Program

The City of Calgary recognizes climate change has implications for our city both now and in the future. We know Calgarians are concerned about climate change, and we’re committed to building a climate-resilient community.

We're working toward reducing greenhouse gas emissions to help limit global climate change, and adapting to a changing climate by taking actions to reduce the impact of extreme weather events and climatic changes.

Our Climate Resilience Strategy


Calgary City Council unanimously approved the Climate Resilience Strategy on June 25, 2018.

The Climate Resilience Strategy outlines The City’s strategies and actions to:

  1. Reduce our contributions to climate change by improving energy management and reducing greenhouse gas emissions (climate change mitigation); and
  2. Respond to a changing climate by implementing risk management measures to reduce the impact of extreme weather events and climatic changes on infrastructure and services (climate change adaptation).

The strategy also complies with federal and provincial regulations and identifies a greenhouse gas emissions target:

  • 80 per cent reduction in city-wide emissions below 2005 levels by 2050

Taking action to reduce the impacts of climate change has the potential to also reduce energy expenditures, improve comfort and livability, improve health and reduce carbon levy costs for citizens, businesses and The City.

The City is committed to delivering on a number of mitigation and adaption actions as part of this strategy. To learn more about the progress we’ve made so far, read our 2020 Annual Report.

Updating our Strategy and Action Plans                                                  

Calgary City Charter requires that the Action Plans be reviewed and updated every five years. This work is currently underway, and the updated strategy and plans will be presented to City Council in 2022.

What’s changing?

We will be updating our strategy and action plans to align with federal direction and are reprioritizing our program areas to better support our goals and priorities. Other key considerations for the update to the Climate Strategy and Action Plans includes, but is not limited to:

  • Integration of new climate science, measures and indicators
  • Integration of climate equity
  • Integration of indigenous world view on climate change and environment
  • Identifying critical actions (‘Big Moves’) for the next five years 
  • Establish the appropriate tools and programs needed to enable climate action

What is climate change?

Climate change is a change in climate patterns, both globally and locally, caused by an increase in greenhouse gas emissions, produced primarily through the combustion of fossil fuels. This change has been occurring for an extended period of time (decades or longer) and is resulting in a shift in the frequency and intensity of extreme weather events as well as a change in where these events might normally occur.

Climate change is a risk multiplier, increasing the severity and frequency of extreme weather events such as flooding, heat waves, winter storms, drought, wildfires and high wind events. Extreme weather events will continue to have increasing impacts on the way we live in terms of our health, natural ecosystems, transportation systems, food security, insurance and recovery costs, as well as how we design and build our homes and cities.

Historical Canadian climate data from 1898 to 2016 illustrates warming trend provided by the Prairie Climate Centre.

Alberta has experienced significant changes to its climate in recent decades. Average annual temperatures in Alberta are expected to increase. We typically experience nine days per year where the temperature is 29°C or above, however, by 2050s we could experience 27 annual heat days and up to 49 heat days by the 2080s, depending on global and local actions to reduce greenhouse gas emissions. Just as a fever can be dangerous in our body, a change of a few degrees can have significant and dangerous impacts on the climate.

Climate modelling tells us that Calgary will experience more severe and frequent extreme weather events such as flooding, drought and the effects of wildfires.

Climate change hazards have worrying implications for cities, including impacts on city water resources, damage to and failure of infrastructure, threats to human health and increased mortality.

This diagram illustrates the likelihood and consequence of the local impacts of and risks from climate change.

How does Calgary contribute to climate change?

In alignment with the Pan-Canadian Framework on Clean Growth and Climate Change, Calgary is doing its part to reduce emissions and drive clean growth. In Calgary, we track the amount of greenhouse gas emissions added to the atmosphere every year through activities that happen within our city boundaries.

Everyday activities such as heating and lighting our homes, moving around the city and disposing of our waste all contribute to the challenge of climate change. Approximately two-thirds of the total greenhouse gas emissions in Calgary are caused by heating, lighting and power demands in buildings. The other third of emissions are due to transportation emissions (gasoline and diesel usage) and 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.
