This proposed Building Regulations amendment 'Part Z' and Proposed Document Z outlines requirements on the assessment of whole life carbon emissions, and limiting of embodied carbon emissions, for all major building projects. The proposal introduces mandatory assessments ahead of setting carbon limits, giving time to converge on robust yet ambitious targets. Proposed Document Z is aligned with the Royal Institution of Chartered Surveyors (RICS) Professional Statement 'Whole life carbon assessment for the built environment', and guidance and recommendations made by the Royal Institute of British Architects (RIBA), the Institution of Structural Engineers (IStructE), the Chartered Institution of Building Services Engineers (CIBSE), the UK Green Building Council (UKGBC) and the London Energy Transformation Initiative (LETI). If adopted, it would rapidly accelerate the voluntary action occurring across our industry, leading to green investment and green jobs creation across construction. The need to introduce carbon regulation is supported by industry leaders, called for by the Climate Change Committee, and we hope that Part Z will be seen as an ‘easy win’ for the UK's roadmap to Net Zero.
