Buildings are responsible for 36% of the global CO2 emissions and need to be reduced by 50% before 2030 if we want to meet the Paris agreement. Therefore, Nearly Zero Carbon buildings must become standard before 2030 and this is best done through regulations. More countries have already set requirements to maximum CO2 emissions from new buildings and the European Commission has suggested that all European countries set requirements to maximum emissions from buildings.

The session will discuss how carbon requirement to new build has been developed (by research) and how to implement them into building legislation (by CO2 requirements) as done in Denmark and other countries. The session will also discuss how the industry needs to declare the carbon content of products and solutions (Environmental Product Declarations) as well as how designers and architects use life cycle perspective and LCA calculations to guide investors in their decision process.
