5 Key Benefits that Reduce GHGs from our Built Environment

Image

Stands the test of time

Concrete structures last for centuries and concrete pavements for decades, reducing the environmental impacts of repair and replacement. What’s more, over the lifetime of a structure or pavement, cement within the concrete reacts with CO2 in the air, reabsorbing part of the CO2 emitted during production.

Innovative Solutions

Innovations like Portland-limestone cement, also known as Contempra, reduces GHGs from concrete, carbon capture and utilization technologies, which could transform concrete into a carbon sink, and ultra-high-performance concrete, which makes for strong structures using less concrete, are part of the solution for a low carbon, sustainable future.

Energy Efficient Buildings

Operational energy use accounts for some 90% of a building’s GHGs. Concrete enables energy efficiency improvements of more than 60% over the National Model Energy Code for Buildings when paired with smart design and technologies.

Produced Locally, Recyclable

Concrete is typically manufactured within 160 km of a project site, using local resources. This greatly reduces shipping-related GHGs. And concrete is 100% recyclable.

Lower Carbon Roads

Concrete roads can save up to 12,000 metric tonnes of GHGs per lane-kilometer over a 50-year period. That’s like avoiding the consumption of 5 million litres of gas.
