About Cleantech & Climate Tech in Canada
Cleantech and climate tech covers clean energy generation and storage, grid technology, carbon capture and removal, hydrogen, industrial decarbonisation, critical minerals processing, and the measurement and reporting software around emissions.
Capital intensity separates this sector from most of the directory: several records describe pilot plants and first commercial facilities rather than shipping products, and each one says which stage it is at.
How this list is built
Every Cleantech & Climate Tech record here is hand-checked, and the 85 claims across them each link to a page you can open. Where a figure is not published, the field is left blank rather than estimated.
