REGULATE EMBODIED CARBON!
REGULATE EMBODIED CARBON!
Greenhouse gas emissions caused by the construction of new buildings and infrastructure, known as ‘embodied carbon emissions’, are a significant driver of climate change.
These emissions amount to just under 50MtCO2e per year in the UK, a shocking figure that is vastly in excess of 10% of our national emissions.
For context; there are 149 countries in the world whose entire national carbon footprint is smaller than the footprint of the UK's construction sector.
Despite this, embodied carbon emissions are unregulated in the UK. Current policy and regulation focuses solely on operational energy use, as distinct from embodied carbon, and there are currently no national planning policy or Building Regulation requirements to assess, report or reduce embodied carbon emissions.
This must change. So ACAN is calling for the urgent introduction of legislation to regulate embodied carbon emissions in the UK. Our demands are backed up by a report, and now we need your help.

THE CARBON FOOTPRINT OF
Embodied carbon emissions are those that are caused by construction processes. They are related to the materials and products that go into making our buildings and infrastructure. These include emissions caused by: extraction, processing and manufacture; transport, assembly and installation on site; replacement, refurbishment and maintenance; demolition and disposal.
These are different from the carbon emissions associated with the energy use (heat and power) of our buildings. Those are known as 'operational carbon' emissions.
As the grid is decarbonised and our new buildings become more efficient in their energy use, embodied carbon is making up an ever greater percentage of a building's total carbon footprint. This can be up to 75% of the total carbon emissions over a typical 60-year lifespan, as illustrated in the diagram below.
Currently, and despite their significance, embodied carbon emissions of buildings are unregulated in the UK. Infrequently discussed in public until recently, they constitute the hidden carbon footprint of buildings. Its time they were regulated.
Government must introduce the following measures;
The Building Regulations
The Building Regulations to be expanded to include requirements to assess, report & reduce embodied carbon, within a new part;
“Part Z: Embodied Carbon Emissions”
Compliance to be achieved through a “Whole Life-Cycle Carbon Assessment” following the British Standard BS EN 15978
Limits placed on embodied carbon emissions set by building type
Regulation 7 to be revised to introduce carbon limits on certain materials
Clauses to be introduced to the National Planning Policy Framework with requirements for Whole Life-Cycle Carbon Assessments to be submitted at three stages for all new buildings; as part of pre-application enquiries, full planning submissions, and at practical completion
New London Plan Policy SI2 to be adopted by local authorities around the UK As an immediate measure
Whole Life-Cycle Carbon Assessment Support
Create a freely accessible UK Environmental Product Declaration (EPD) database, or adopt an existing freely accessible database, to ensure consistent and reliable assessments
Require Environmental Product Declarations to be submitted to the database from construction material suppliers above a certain size, with trade bodies assisting smaller organisations.
Establish a freely accessible database for anonymised Whole Life-Cycle Carbon Assessment data of new buildings, to ensure lessons are widely learnt
