Don't just say carbon footprint against carbon emissions. When talking about a building's carbon footprint, you have to make the important split between embodied and operational carbon footprint. But what exactly is it?
Do you want to reduce your operational carbon footprint? Then you have to insulate better. You can also see that on your EPC (energy performance certificate), which is becoming increasingly important. That also means: the better a building's EPC score, the lower its operational carbon footprint.
Also, the embodied carbon footprint is becoming increasingly important. Where materials come from, how they are made and how sustainable that whole process is, is a topic that clients, architects and contractors are increasingly concerned about. Producers of building materials need to keep reinventing themselves to get that footprint as low as possible.
