Embodied Carbon Calculator for Concrete Block Units
Explore this practical online tool that lets you estimate the embodied carbon (global warming potential) of an individual concrete block unit — simply by entering its size, weight, cement type, and the Canadian region where it’s manufactured. It’s a free calculator based on industry-standard Environmental Product Declaration (EPD) data, making it useful for architects, engineers and sustainability-minded builders looking to understand the carbon footprint of masonry materials.
Embodied Carbon Calculator for CMU Wall Assemblies
This interactive tool lets you estimate the embodied carbon footprint of a concrete masonry unit (CMU) wall assembly. By selecting wall components, insulation, finish options, and regional data, you can quickly compare design alternatives and see how choices impact climate-change emissions. It’s based on current industry Environmental Product Declaration (EPD) inputs — a helpful resource for designers, builders, and sustainability professionals focused on low-carbon construction.
Welcome to CCMPA’s Carbon Calculator
For years, designers have been making the decision to specify concrete masonry wall assemblies in their designs for user comfort, safety, superior resistance to disaster/fire/mould, acoustic benefits, and operational energy-efficiency – among other things.
Now you have the opportunity to choose concrete masonry wall assemblies for carbon transparency. The Canadian Concrete Masonry Producers Association is providing this free, downloadable Carbon Calculator to quantify the carbon footprint of your designs.
This downloadable tool:
- allows you to estimate the cradle-to-gate carbon associated with constructing a concrete masonry wall;
- is based on available published environmental data on products involved in concrete masonry construction;
- comes with a simple reference, assumptions, and limitations document for full environmental and technical transparency; and
- provides you the flexibility to input climate zone, wall size/area, material volumes and types, and in return you get a cradle-to-gate estimate of the CO2 footprint for that construction.
