UKGBC launches first ever UK Roadmap for achieving a net zero built environment by 2050

The UK Green Building Council has launched a new roadmap detailing the actions needed by government and industry to get the UK built environment to net zero by 2050.

Co-created by industry with over 100 organisations contributing, the Whole Life Carbon Roadmap provides a shared vision and set of actions for achieving a net zero UK built environment by mid-century, in relation to construction, operation and demolition of buildings and infrastructure. It is the first quantification of the carbon reductions required each year from buildings and infrastructure in the lead up to 2050.

The analysis includes not only domestic emissions, but emissions related to the consumption of imported construction products and materials.

The built environment is directly responsible for 25% of the total UK carbon footprint, and therefore has a critical role to play in the national transition to net zero. A transformative shift in industry practices is required and so action plans are provided for 14 key stakeholder groups.

Closing policy gaps

The Roadmap highlights the growing need to quickly close the policy gap on net zero homes and embodied carbon. The UKGBC says that with homes responsible for 16% of total UK carbon emissions, government must immediately bring forward a national retrofit programme to unlock significant carbon savings, as well as deliver high-quality and cheaper to heat homes for people

The Roadmap also sets out policy recommendations for central and local governments to help drive and enable the transition needed to decarbonise the sector. These go beyond the recently published UK Government Heat & Buildings strategy and cover existing homes, existing non-domestic buildings and new buildings as well as for the infrastructure which connects our buildings and industry.

Key recommendations

The recommendations include:

1) Nation-wide retrofitting of existing homes:

  • Establish an immediate national programme of “fabric first” home retrofit to make homes efficient, warm, and transition away from fossil fuel heating.
  • Bring forward the cut-off date for the sale of gas and oil boilers to 2030.
  • Reform EPCs and introduce minimum EPC ratings for homes at point of sale by 2028.
  • Remove VAT on energy efficient retrofit building works and introduce variable stamp duty linked to energy performance.
  • Introduce direct government retrofit grants for low-income households.

2) Energy performance disclosure for non-domestic buildings.

3) Adoption of a design for performance approach to new buildings.

  • Reform building regulations to introduce Energy Usage Intensity (kWh/m2/yr) targets for new buildings from 2025. Alongside low carbon heating for all new buildings from 2025, introduce space heating demand limits (kWh/m2/yr), measures to limit peak demand, and minimum standards for currently unregulated key appliances. 

4) Whole life carbon measurements and agreed limits.

  • Introduce the regulation of embodied carbon for new buildings and major refurbishments
  • Support and invest in industrial decarbonisation of key construction material supply chains
  • Use planning reforms to prioritise reuse of existing buildings and assets

5) National infrastructure investment based on the net emissions impact.

  • Establish a National Infrastructure Integrator with full oversight of carbon impacts

The Roadmap was co-created by the industry through a project Steering Group and four Task Groups with over 100 organisations contributing. Many of the recommendations align with existing industry initiatives such as Construct Zero from the Construction Leadership Council, and the Construction Industry Council’s Climate Action Plan as well as those contained in the recently published Scottish Government Heat & Buildings strategy. In some cases, the recommendations build on existing Government policy initiatives to facilitate adoption of further proposals and timelines.

Julie Hirigoyen, Chief Executive at UKGBC said: “After all the talk, it’s time for action. The UK Government’s Heat and Buildings Strategy is a step in the right direction but fails to address several key priorities that this analysis clearly demonstrates are non-negotiable to achieving a net-zero carbon built environment by 2050. The Net Zero Whole Life Carbon Roadmap pulls together disparate strands of recent policy and action into one coherent pathway, with clear recommendations for National Government and Local Authorities, as well as the private sector and the wider industry. We urge policy-makers and industry to embed these recommendations into policies and strategies to make good on the promises and commitments of COP26.”
