A Carbon Calculation
An example of using the carbon calculator
is provided based on a recent
project that Keller completed in New
York. The ground improvement solution
selected by the client was rigid
inclusions. By performing a carbon
calculation on the original design, the
project team could easily see that the
materials were driving the carbon
footprint of the solution. Therefore,
Keller worked with the ready-mix
supplier to find multiple ways to
optimize the grout mix design for the
project, leading to a carbon savings of
more than 1,000 tons CO2e.
More examples of how the carbon
calculator has been successfully
implemented on real projects are
provided in the reoccurring Deep
Founda t i ons magaz i ne co l umn ,
Foundations for a Sustainable Future.
Those articles can be accessed for free
on the DFI Sustainability Committee's
webpage and can be used to demonstrate
internally or to clients how a
carbon calculation can guide projects
to the lowest carbon, and often lowest
cost, foundation solution.
Conclusion
The positive impacts that reducing
carbon emissions has on the environmental
and social side of sustainability
are commendable reasons to
change the way the deep foundation
industry operates. However, the third
pillar of sustainability, economics, is
quickly becoming a more important
factor when considering why the
industry needs to address its carbon
emissions. By measuring and reducing
the carbon footprint of the solutions it
designs and builds, the industry meets
its own operational needs by mitigating
the worst effects of climate
change; meets clients' needs as more
stringent reporting and financing
rules come into play; and accomplishes
individual companies' goals of
contributing positively to the SDGs.
Using the carbon calculator, a free,
standardized and certified tool, provides
the abi l ity to make these
changes in a meaningful, measurable
and impactful way.
