Coordinated engagement with
- suppliers and trade associations to provide EPDs
- industry initiatives to share data and review defaults
- material sectors to understand decarbonisation plans
- Homes England / DLUHC / BEIS / UKNZCBS / BECD

• WLC Oversight Group meets every 3 months to share progress and take input from the wider WLC and homebuilding community

• Draft new homes assessment framework published in FHH Implementation Plan

• Working groups develop the WLC conventions for new homes and background data tables for the tool.

• Publish draft conventions and data tables

• Working with commercial tool providers to incorporate the FHH conventions into other tools.

• Working groups meet to review latest data available for buildups, materials and life cycle assumptions

• Review and update proposed assessment framework for new homes if appropriate.
• Update published generic materials table
• Update published buildups table

• Industry engagement with larger developers, SMEs and manufacturers to define scope and requirements for a simple WLC tool for homebuilders.

• Develop simple tool for launch to Hub members in March 2024.

• Further tool versions add funtionality every 3 months

• Tool v2 launch to Hub members - enables user defined materials and buildups.
• Enables as built reporting, which will feed into benchmarking.

• Tool v3 launch to Hub members - includes infrastructure site elements.
• Enables whole project reporting per the draft new homes assessment framework.

• Benchmark for low rise homes based on phase 1 study (35 assessments, ~10 developers)

• Make it easy for new homes developers to share disaggregated data about carbon impacts, material quantities and high-level project info.

• Voluntary disclosure of pilot projects for plot-level carbon.
• Gather and share disaggregated data from existing assessments within the Hub.

• Once the v2 tool has launched, we can start using it to collect WLC data from developers.
• We will also be able to accept detail exports from Oneclick and other commerical tools, which use the FHH conventions.
• Call for all Hub members to start using the tool, endorsed by the CEO council.

• Publish robust benchmarks based on all data gathered to date.
• These will also be available for reference within the tool.
• Annual or more frequent update of benchmarks tbc

• Indicative target levels set initially as part of Hub's Net Zero Transition Plan for the homebuilding sector

• Once the measure is consistent and benchmarks understood, developers can begin to create a targeted approach to reduction.

• Target levels reviewed and updated on an annual basis tbc in line with Hub Sustainability Framework

• Working groups identify the common buildups and generic materials for new homes.

• Call for material sectors to improve generic data + engage with Working Group 2
• FHH to work with engaged material / product sectors to improve / keep reference data up to date

• Start measuring extent of product manufacturer specific data used in assessments - EPD coverage

• Set interim target level of EPD coverage for developers / manufacturers to meet
• Identify hot spots (high carbon impact, few EPDs)

• Target full EPD coverage of all key components
