Our indices measure the carbon emissions intensity of the 15% least polluting housing stock for carbon dioxide mass equivalent operating emissions per square meter per year (kgCO2e / m2 / year).
Currently this level of performance is broadly thought to represent the threshold for alignment of housing assets with the Paris Climate Agreement. Our indices are a reflection on where the best performance is, a target for other properties to meet.
Until now there has been no clear and precise way of determining how much progress we are making in decarbonising the housing stock, we had no idea if we are on track to become net zero by 2050 or not. This inspired us to create the first index measuring the carbon emissions intensity of the avant-garde, or 15% least polluting housing stock.
For the first time it is possible to monitor our housing stock to ensure that collectively, we are moving at the right speed to achieve decarbonisation.
