CO2 Footprint and Deerns Multiplier

Our most effective way to accelerate sustainability still is COreduction in our projects by our advanced and innovative energy concepts. At the same time as helping our clients to create an energy efficient building, we are challenging ourselves to reduce our overall carbon footprint. Our environmental performance reflected in our net carbon footprint improved by around 27% compared to 2009. 

Reducing our own environmental footprint

Over the past year we managed to reduce our overall carbon footprint to 4.45 tonnes per fte which means we are on track regarding our 2017 goal of 3.8 tonnes per fte. Our travel kilometers generate the greater part of our COemissions. This is the reason we compensate for air travel related COemissions via the Climate Neutral Group. We stimulate sustainable behaviour via the use of public transport. In our offices the use of ‘green energy’ has increased substantially and several have moved to more sustainable and energy efficient locations or reduced their office space. We request our suppliers to comply with our standards and encourage our staff to handle energy and raw materials responsibly.

Reducing the carbon footprint of our clients

Our most effective way to accelerate sustainability still is COreduction in our projects by our advanced and innovative energy concepts. The Deerns Multiplier shows our achievements in comparison to our own environmental impact. In 2016 the CO2 savings in our most sustainable projects over the entire lifespan amounted to 1,565 times our own annual COemissions caused by our own business operations. Since 2010, Deerns has published the Deerns Multiplier showing the amount of COemissions that we are saving with our sustainable projects compared with the amount of COemissions that our operations produce. This number indicates the relevance of our designs for society in general and for our clients in particular. 


Minimalise the use of materials 

Next to energy savings and the reduction of COemissions also use of materials has a substantial impact on the environmental care within the built environment. In our role as a professional consulting firm we take responsibility to stress the relevance of sensible material usage in construction projects and developed the Materials Multiplier to demonstrate the material usage savings. Our most recent projects have produced a Materials Multiplier of 397. In other words, we have 'saved' almost 400 times on environmental impact with our advice in projects in terms of material usage than we have produced with our own premises.
