Overview

The Carbon Emissions (Buildings) Bill aims to reduce the carbon footprint of buildings in England and Wales by mandating the reporting of whole-life carbon emissions and setting limits on embodied carbon during construction. This will apply to new builds and significant renovations of larger buildings and developments.

Description

Whole-Life Carbon Reporting

The bill amends the Building Regulations 2010 to require reporting of whole-life carbon emissions (operational and embodied) for buildings over 1000m² or creating more than 10 dwellings. This includes new builds and substantial renovations. A methodology for calculating these emissions, a reporting platform, and approved assessment tools will be established by the Secretary of State.

Embodied Carbon Limits

The bill introduces limits on upfront embodied carbon emissions (those associated with materials and construction before completion). These limits, set as target CO2e rates, will be determined by the Secretary of State and will apply from January 1st, 2027.

Accreditation and Certification

A system for accrediting whole-life carbon assessors will be created. These assessors will be responsible for verifying the carbon emissions calculations and issuing certificates. Competent persons using approved tools can also carry out assessments until an accreditation scheme is approved.

Enforcement

Builders will be required to submit notices to local authorities before and after construction, detailing calculated carbon emissions and adherence to specifications. Local authorities will be authorized to accept certificates from accredited assessors.

Timelines

Whole-life carbon reporting for non-dwellings starts December 31st, 2023, and for dwellings January 1st, 2025. Embodied carbon limits begin January 1st, 2027.

Government Spending

The bill doesn't specify direct government spending figures. However, costs will be associated with establishing the reporting platform, approving methodologies and accreditation schemes, and potential enforcement activities. Conversely, long-term savings could be achieved through reduced carbon emissions and improved energy efficiency.

Groups Affected

• Builders and Developers: Will face new reporting and compliance requirements, potentially increasing project costs and complexity.
• Architects and Designers: Will need to incorporate whole-life carbon considerations into their designs.
• Local Authorities: Will be responsible for receiving and reviewing the submitted reports and certificates.
• Material Suppliers: May need to adapt their offerings to meet the lower embodied carbon limits.
• Homeowners and Tenants: May indirectly benefit from lower energy bills and a reduced carbon footprint of their buildings.
• Environmental Groups: Likely to view this as a positive step in addressing climate change.
