Amrize modernizes Montreal area cement plant to cut carbon emissions by 40 percent by 2035

Amrize broke ground on a modernization project at its Saint-Constant cement plant near Montreal. The upgrade will introduce high efficiency equipment to improve production, energy use, storage and logistics. The plant expects to cut its net carbon footprint by over 40 percent by 2035, making it the lowest carbon cement producer in Eastern Canada. Production capacity will increase by 300,000 tonnes to a total of 1.2 million tonnes per year, and the workforce will grow by 25 percent. The project receives support from the Government of Canada through the Low-Carbon Economy Fund and from the Government of Quebec through the EcoPerformance program and the Support Measure for the Decarbonization of the Industrial Sector. Both Quebec programs are funded by the Quebec Carbon Market. The announcement comes alongside a broader Canada-Quebec infrastructure partnership worth nearly $10 billion over the next decade for local infrastructure, transit, healthcare and housing. This is a concrete example of carbon market revenues being channeled into industrial decarbonization. Cement production is a major source of industrial emissions, and this project shows how policy tools like carbon pricing and targeted grants can drive real reductions while expanding local manufacturing and jobs.
