This is a positive step forward and will help the construction sector to tackle its large environmental impact. It is encouraging to see that the framework includes embodied carbon, which is all too often overlooked.
How do you achieve net zero carbon?
Achieving Net Zero Carbon Construction
In order to achieve net zero, the following steps are defined in the framework:
- Establish net zero carbon scope
- reduce construction impacts
- Reduce operational energy and carbon impacts
- Increase renewable energy supply
- Carbon offset the remainder of emissions
The final step is to offset the remaining carbon emissions. Read more about carbon offsetting in our article.
What is the Embodied Carbon of a Typical Building
range 400 - 1,000 kg CO2e per m2 GIA"
What Are the Costs of Offsetting Carbon for Net Zero
Assuming an average carbon offset price of £5 a tonne CO2 and assuming that a building would need to offset half a tonne of CO2 per m2 GIA, the below costs would be incurred from procuring the carbon offsets:
- 100 m2 house = £250
- 1,000 m2 building = £2,500
- 10,000 m2 building = £25,000
Circular Ecology are able to procure verified carbon offsets from a range of reputable projects.
