One unexpected way to offset your CO2 emissions in 2019 - with a concrete slab

There are many advantages to renewing existing concrete surfaces, compared to ripping out the old concrete and re-pouring anew. We talked here about the structural perils of demo-ing residential and commercial pool decks, and that you have a big appetite for risk to do it. Could you even imagine the headache of changing out a worn concrete slab that was built on-top of a commercial parking garage, or that of a cracked walkways in front of a retail stores?


The concrete industry is responsible for 8% of the world's carbon dioxide CO2 emissions. Pictured here a typical cement plant with smoke stacks.

(The time needed for the installation, limited access, noise, dust levels and costs associated with such an adventure make it for many prohibitive.)


Besides these practical hurdles of pouring new concrete, have you ever considered the impact your decision can have on your CO2 footprint?


We did the math, and it doesn’t look pretty when you are a fan of new concrete!


Concrete is a very common building product (in fact it is THE most commonly used building product in the world). Concrete is very strong, but it is also very heavy. Per cubic foot, concrete adds a staggering 150 pounds to the scale.

A key component of any concrete mix is cement, which produces a very high amount of CO2 in manufacturing. Carbon dioxide (CO2) is one of the greenhouse gases that contribute to the warming of the Earth's atmosphere. It is estimated that 180 kg of carbon dioxide emitted during the production of one tonne of concrete. The result is an incredible 1 tonne of CO2 per 200 square feet of new concrete pour, or 6 tonnes of CO2 for an average 1,200 sft pool deck!
