Environmental Metrics
The new homes sector has come together to create a framework to report key environmental metrics consistently.
The Future Homes Hub, working with a set of leading developers, financial institutions, and other key stakeholders, is continuing with its goal to define a common language to describe sustainability performance.
Our Goal
“Consistent and robust environmental performance measurement across homebuilders and the sector.”
Objectives
Three objectives support this goal:
- To define a common language for sustainability performance across the new homes sector, according to clear, standardised and unambiguous methodologies
- To enable consistent and comparable sustainability reporting, supporting homebuilders to align with future regulatory, stakeholder and investment reporting expectations
- To guide the sector to instil good data culture and increase its familiarity with reporting environmental performance metrics across the spectrum of developers
Context
While leading homebuilders are advancing rapidly in their efforts to report environmental performance, other organisations who lack the resource and skillset are often left behind. At the same time, there is a wide range of often overlapping reporting frameworks, providing a confusing landscape for those homebuilders who are interested in beginning their reporting journey.
As such there are many ways of measuring many different aspects of environmental performance. We wish to help the sector measure the same things in the same way.
External stakeholders, standard setters and investors are increasingly requiring an understanding of homebuilder sustainability performance to make evidenced judgements. The New Homes Environmental Metrics condenses the key environmental sustainability topics necessary to support these decisions, while making the process of reporting as straightforward and accessible as possible. Some key use cases are described in the launch brochure.
We are working with key sustainability benchmarks and frameworks including NextGeneration and B4NZ to align metrics where relevant, reducing duplication and developer effort. This will continue as we work towards finalising the full set of environmental metrics.
Environmental metrics for the sector were originally proposed in the Future Homes Delivery Plan, with subsequent commitments made in Future Homes, One Plan and One Plan: scaling up delivery.
Core Metrics
We published our Core Metrics, suitable for all developers, in October 2025. After a transition year where developers have been getting to grips with the Reporting Toolkit, we expect to be able to start to collect data from October 2026.
Reporting toolkit
The Reporting Toolkit currently covers Core Metrics.
The metrics toolkit comprises two documents: a technical manual providing methodologies and instructions, and a spreadsheet-based reporting tool to allow metric reporting to the Hub.

Extended Metrics
In parallel we are deep into the next phase of work and anticipate publishing a set of Extended Metrics, suitable for developers more advanced in their approach, in 2026.
Next steps
As next steps, we will collect both Core and Extended Metric data sets, review data quality and generate benchmarks prior to data aggregation and publication of sector performance. Looking further ahead, it is our ambition to translate across to a digital tool, with more streamlined approaches to data assurance and benchmarking. We will continue to support the sector to improve the quality and ease of reporting and to instil good data culture.
