Update: see latest post Construction Carbon Calculator – no more excuses for best yet calculator
Zero Champion in a recent post poses the question ‘How the hell do we measure our carbon footprint‘?
Businesses need a single, unified standard for displaying the carbon impact of their activities to ensure companies can see a visible competitive advantage to sustainable development.
This made me think and look around for a construction process carbon calculator – and surprisingly did not find too many, and most linked to some carbon offsetting (carbon off-putting) scheme, which makes me doubt the formula being used.
If you want to take a look at a couple :
C Level has a calculator, but lacks many energy aspects (fuel on site, small tool and lighting, office energy and resources) and is linked to their off setting scheme. C Level lists constructing excellence as one of its customers.
Over in the states BuildCarbonNeutral has an interesting approach focusing on the embodied energy released through construction and the life of a building. It also contains the following comments
13-18% of the total embodied carbon footprint of any construction project (UNEP, 2007) and 100% of the total embodied carbon footprint of any landscape project is released the year the project is built or installed. The remainder of the carbon footprint is the operational carbon released and the landscape carbon sequestered over the life of the project.
Embodied construction carbon is a more significant factor than air travel, and has an equally immediate impact.
Does anybody out there know of any reliable, unbaised (ie not linked to carbon offsetting schemes) for the construction process?
