Whenever a member hunts for ways to lower whole life carbon it works through the reduction hierarchy in the order given and can show it weighed each rung. The first rung is to avoid: line the scheme's outcomes up with the system-level move to net zero and question whether the asset or network is needed at all, which includes not building, or reusing, retrofitting or repurposing what already stands. The second is to switch: weigh alternatives and pick one with lower whole life emissions through a different scope, design approach, material set or technology, while still satisfying the whole life performance brief. The third is to improve: adopt solutions and techniques that use resources better and lengthen design life, with circular economy thinking about what can be reused or recycled once the asset is finished with.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
