In order to reduce carbon emissions it is first necessary to measure them. This can be done in different ways - in the UK for example by using BS EN 159781 the life cycle of the structure can be split into four stages as shown below, and the emissions assessed at each stage.
The distribution of emissions at each stage breaks down in approximately in these proportions:
||Typical distribution of emissions
It can be seen that the largest portion of emissions occurs at the Product Stage, and this is the stage that can be targeted by Tekla Structural Designer to make savings.
