Our EPDs provide transparent whole-life carbon data to support specification, Whole Life Carbon Assessments (WLCA), BREEAM assessments and sustainable building design.
Provides cradle-to-grave lifecycle data for more accurate Whole Life Carbon Assessments.
Developed to EN 15804+A2, ISO 14025 and ISO 21930.
Consistent data for reliable product comparisons.
Supports WLCA, BREEAM, Future Homes Standard and net zero carbon projects.
Products may be reported using different units such as m³, m² or kg. H+H EPDs use 1m³ of aircrete as the declared unit.
Measured in kgCO₂e, GWP indicates the greenhouse gas emissions associated with each lifecycle stage.
Comparisons should only be made between EPDs reporting equivalent lifecycle stages to ensure fair assessment.
All compliant Environmental Product Declarations (EPDs) report the product stage (A1–A3), end-of-life stage (C1–C4), and Module D, which covers the benefits of reuse, recovery and recycling beyond a building's lifecycle. H+H EPDs provide a more comprehensive assessment by also including transport and installation (A4–A5) and the full in-use stage (B1–B7), including maintenance, repair and replacement. This broader scope provides a more complete and accurate understanding of a product's environmental performance throughout its entire lifecycle.
Accurate sustainability reporting requires consideration of whole-life carbon rather than focusing solely on upfront emissions. While cradle-to-gate (A1–A3) and upfront carbon (A1–A5) values provide useful information, they do not represent a product's full environmental impact. Following the RICS Whole Life Carbon Assessment (WLCA) Standard ensures that all lifecycle stages are considered, including the treatment of biogenic carbon and its release at end of life, providing a more complete picture of long-term building performance.
H+H aircrete combines independently verified environmental data with proven building performance to support more sustainable construction. Excellent thermal performance helps reduce operational energy demand, while a service life exceeding 100 years and the ability to recycle material at end of life contribute to lower whole-life environmental impacts. Supported by transparent, third-party verified EPDs, H+H aircrete is regularly specified on projects designed to meet Future Homes Standard requirements, achieve Passivhaus certification, secure BREEAM credits and reduce whole-life carbon.
Environmental Product Declarations are available for our Standard Grade, Solar Grade, High & Super Strength Grade aircrete blocks, and Vertical Wall Panels. Each EPD can be downloaded directly from this page.
H+H EPDs provide independently verified environmental data that can be used to support Whole Life Carbon Assessments (WLCA), BREEAM assessments, net zero carbon strategies and sustainable specification decisions.
All H+H EPDs are based on a declared unit of 1m³ of aircrete, providing a consistent basis for comparing environmental performance and calculating embodied carbon.
Yes. All H+H EPDs are independently verified and developed in accordance with EN 15804+A2, ISO 14025 and ISO 21930.
H+H EPDs report whole-life environmental impacts, including product, construction, use and end-of-life stages, providing a more complete assessment than product-stage reporting alone.
EPDs should be used during specification and design to compare construction products, assess embodied carbon and support sustainability reporting throughout the project lifecycle.
