3、n emissions,those associated with building components,by 2030.As demonstrated in the previous Net-zero buildings:Where do we stand?report1,as buildings generally become more energy efficient,in some cases embodied carbon already accounts for more than 50%of a new projects whole life carbon footprint

4、.Importantly,a major component of this embodied carbon is the upfront carbon associated with the initial construction process and hence reaching the atmosphere at the very outset(figure 1).Although some of these carbon emissions are currently considered hard to abate,we can,and we must,aim higher an

5、d immediately develop buildings with significantly less embodied carbon if the sector is to achieve the overall net-zero targets we strive for.In the Where do we stand?report,we point to what we need to do.The aim here is to point out strategies that will highlight the possibilities of how we achiev

6、e the systemic changes we require.Time is running out,so it is essential to work with what is available today,without over-relying on major future technological advances.We must rethink the way we do things,questioning everything and adapting current practices under the lens of major reduction poten
