Scottish City Region and Growth Deals: carbon management guidance for projects and programmes
Guidance for project owners on managing carbon emissions associated with Scottish City Region and Growth Deal projects.
The following definitions have been adopted for consistency. They are based on an internationally-recognised carbon management specification (PAS 2080: Carbon Management in Infrastructure) and are applicable to all Deal projects.
- Carbon: Shorthand for all greenhouse gases emissions as defined by the Kyoto Protocol, measured in kg or tonnes of carbon dioxide equivalent (CO2e);
- Capital Carbon: Carbon associated with the creation, refurbishment and end of life treatment of a project, e.g. construction materials and processes. The related term 'embodied carbon' is usually used at a product or material level, whereas capital carbon will have greater relevance at a project level;
- Operational Carbon: Carbon associated with the operation of a project required to enable it to deliver its service or outcomes, e.g. electricity use or building heating;
- Whole Life Carbon: The sum of carbon from all stages of the life cycle of a project. For the purpose of this definition, this sum includes indirect changes in carbon expected to result from the project (decreases or increases), e.g. a reduction in atmospheric carbon or an increase in vehicular emissions (also referred to as End User carbon).
- Carbon Emissions Impact: The Green Book guidance equivalent to whole life carbon, which requires to be stated in the economic case for projects seeking public sector funding;
- Net Zero Carbon: Where the sum of the carbon emissions resulting from a project and the carbon it removes from the atmosphere equals zero. Noting that carbon savings against a 'business as usual' scenario do not necessarily represent carbon removed from the atmosphere;
- Carbon Control: Where project owners have the ability to manage, through direct requirement of project design and operational approach, specific objectives for capital and operational carbon emissions; and,
- Carbon Influence: Where the project may affect carbon emissions beyond carbon control, notably through the use of project buildings or infrastructure. For example, a project owner can 'control' the carbon associated with a new road (design, construction, maintenance, lighting, etc.) but can only 'influence' the carbon emitted by users of the road.
