On top of 6.1 together with 6.2.1, the owner or manager issues design requirements that keep the scheme in step with the net zero transition; buys design and delivery services on whole life decarbonisation; chooses a study boundary that takes in every relevant source of whole life carbon, user carbon included where it matters, accepting that this may reach beyond the scheme boundary; brings standards and guidance into line with whole life decarbonisation; applies suitable methods for quantifying emissions and removals both within its control and within its influence; can show it has weighed options that make the most of existing assets where that is the lowest-carbon result; and runs a system for applying circular economy thinking through planning, design, construction, operation and end of life, working with stakeholders on the useful exchange of resources.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
