Greenhouse gas emissions dashboard
Ottawa’s Greenhouse Gas (GHG) Emissions Inventories track progress toward Council-approved greenhouse gas reduction targets.
he dashboard includes two inventories:
- Corporate emissions from City operations like buildings, fleet, solid waste, and wastewater.
- Community emissions which come from key sectors such as buildings, transportation, waste and agriculture.
These inventories capture both direct and indirect emissions and follow internationally accepted accounting principles to ensure consistent and transparent reporting.
As approved in the Climate Change Master Plan (CCMP) Council’s long-term targets are to reduce community emissions by 100 per cent by 2050 (net-zero) and corporate emissions by 100 per cent by 2040 with 2012 as the baseline year. A baseline year is a reference point in time against which emissions or performance metrics are measured over the years. The interim targets for the corporate emissions are 2025 (30 per cent reduction), 2030 (50 per cent), and 2040 (100 per cent). These targets for the community emissions are 2025 (43 per cent), 2030 (68 per cent), 2040 (96 per cent), and 2050 (100 per cent).
The City’s GHG emissions are tracked each year and are published once all of the data is collected and validated. It can take up to a year to publish the previous year’s data. Some information is provided by the provincial and federal governments, which can take more time to release. The online dashboard will be updated once all of the data is available and validated.
What's included in the inventories?
Corporate inventories track emissions from municipal operations in four sectors:
Facilities: buildings, streetlights, and traffic lights
Fleet: municipal, transit, and police fleets
Solid waste: the Trail Road Waste Facility and former Nepean landfill
Wastewater: treatment of wastewater at Robert O. Pickard Environmental Centre
Community inventories track total emissions from activities within the geographic boundaries of Ottawa (including emissions from municipal operations) in four sectors:
Buildings: residential, commercial, institutional, and industrial sectors
Transportation: on-road, aviation, railway, and off-road transportation
Waste: public and private landfills and wastewater treatment
Agriculture: crop production and livestock operations
What are the data sources?
Corporate: Operational data reported by City departments such as energy use and fuel consumption.
Community: Utility data (e.g., Hydro One), fuel suppliers and provincial datasets. Provincial and national datasets use the Ottawa to Ontario proportions to reflect Ottawa’s share.
What influences results from year to year?
There are many things that can influence emissions results. These include:
- Data availability and accuracy
- Population change
- Weather
- Regulatory or technology shifts
- Energy prices and availability
- GHGs created from energy sources
- Changes in consumer behaviour
Accuracy: The greenhouse gas emissions dataset is currently in beta; the structure and content may change without notice. While every effort has been made to ensure the accuracy and veracity of the information on this website, the City of Ottawa is not responsible in any way for damages arising out of the use of this website. And, although the City of Ottawa relies on reputable sources and believes the information posted on the website by the City is correct, and attempts to keep the information current, the City of Ottawa does not warrant the accuracy or completeness of the information.
