Overarching principles:1. Polluter pays
2. Improve measurement and transparency
3. Encourage action today and tighten requirements over time

UKGBC - Together for a better built environment
Reduce construction impacts
Reduce operational energy use
Increase renewable energy supply
Offset any remaining carbon
Public disclosure
= Achieve net zero carbon balance for construction= Achieve net zero carbon balance for operational energy

UKGBC - Together for a better built environment
1. Carbon & energy demand reduction
2. Mitigating overheating risk
3. Assuring performance
UKGBC - Together for a better built environment
1. Energy and carbon improvements� 19% carbon reduction on Part L 2013� Meet Part L requirements solely through energy efficiency
2. Address overheating risks� Cooling hierarchy � Screening, dynamic modelling for risks
3. Reduce the performance gap� Developer’s internal quality controls� Third party processes - BEPIT, NEF Assured Performance Toolkit � Relevant certification - HQM, Passivhaus, Energiesprong

Referable schemes:1. Whole Life-Cycle Carbon Assessment2. Outline actions taken to reduce life-cycle emissions3. Circular Economy Statement:
• Re-use/recycling of materials from demolition and remediation
• Disassembly and re-use of materials at the end of the building life
• Waste management and handling
Local leadership:Embodied carbon
