The City of Hamilton has introduced a carbon budget and accounting framework designed to help municipal leaders assess the climate impacts of major decisions and support long-term planning as the city works toward net-zero greenhouse gas emissions by 2050.
The framework, approved as part of Hamilton’s ongoing climate strategy, will apply a climate lens to municipal decision-making on infrastructure projects, road construction, equipment purchases, new buildings and other capital investments.
Mayor Andrea Horwath said the initiative will help the city respond to growing climate challenges while continuing to deliver essential services.
“The impacts of climate change are already being felt in Hamilton, from more frequent extreme weather events to increased pressure on the infrastructure and services residents rely on every day,” Horwath said in a statement.
“This framework will help ensure we are making informed decisions that support a healthier, more resilient and sustainable city for current and future generations.”
The carbon budget is based on a global fair-share approach aligned with the Paris Agreement and the international goal of limiting global warming to 1.5 degrees Celsius above pre-industrial levels.
Under the framework, Hamilton’s total allowable emissions are estimated at 422,000 tonnes of carbon dioxide equivalent for municipal operations and 53 million tonnes of carbon dioxide equivalent across the broader community.
City officials said the framework builds on Hamilton’s existing Climate Action Strategy and will be introduced through a pilot phase during the 2027 budget process. The initial rollout will focus on selected city divisions and capital projects valued at more than $250,000, with refinements planned through 2030.
“A carbon budget gives the City another important tool to understand the climate impact of our decisions in the same way we consider financial impacts,” said City Manager Marnie Cluckie. “By building this into our planning and budgeting processes, we can make more responsible, forward-looking choices that manage risk, identify opportunities and support a more sustainable and resilient Hamilton.”
The framework also includes a voluntary community carbon budget self-reporting process aimed at helping residents, businesses and organizations track and reduce emissions.
Although municipal operations account for less than 1% of Hamilton’s total community-wide emissions on average, city officials said local government can demonstrate leadership through its own operations and by expanding lower-carbon options for residents and businesses.
Beginning in 2027, Hamilton’s annual budget documents will include greenhouse gas emissions estimates for identified city projects. The Office of Climate Change Initiatives will also report annually on both corporate and community emissions inventories, along with performance indicators established under the framework.
City officials say the new approach will help ensure climate considerations become a regular part of municipal planning and investment decisions as Hamilton pursues its long-term emissions reduction goals.
