Decarbonisation Strategy of the Year

Winner:

Interface

All In

Interface won edie’s Decarbonisation Strategy of the Year Award for “All In”, a strategy that has seen the global flooring manufacturer go all in on direct carbon reduction and carbon storage, and cease the use of offsets.

The challenge

Interface’s environmental strategy is anchored in its SBTi-validated 2030 targets, which guide every operational and design decision. Meeting them requires reducing emissions across all scopes – and particularly Scope 3 – while demonstrating how a global manufacturer can decarbonise at speed without compromising on quality or performance.

The solution

Interface has eliminated offsets and invests exclusively in direct carbon reduction – a decision that has sparked meaningful conversations across the manufacturing sector, encouraging others to follow suit.

The strategy centres on material research and development and avoiding emissions through thoughtful design: changing material usage to create products with more recycled content that last longer and can be easily recycled. Durability is a priority, since longer-lasting floors mean fewer replacements and emissions over time, while modular flooring uses less material and cuts installation waste.

Transparency is central. All Environmental Product Declarations, carbon data, certifications and tools – including Interface’s Carbon Calculator and embodied carbon resources – are freely available on its website, empowering customers to make informed, low-carbon choices.

How the project works

Innovations in backings allow Interface to deliver impact at scale. Its CQuest™Bio and CQuest™BioX backings use carbon neutral and carbon negative materials without compromising performance, and carbon negative CQuest™BioX – which stores more carbon than is emitted across the supply chain – is offered as standard on all carpet tile products. In 2025, Interface also added captured carbon to its carpet tile manufacturing processes.

Interface’s latest rubber flooring innovation, noravant timber, has a carbon footprint of just 3.41 kg CO2e/m² – one of the lowest in rubber – combining the performance of rubber flooring with the aesthetics of wood. The company has also created a one-of-a-kind carbon negative nora® rubber prototype.

At end of life, the ReEntry programme prioritises reusing tiles to keep product out of landfill, or recycling used product into something new. In 2025, Interface increased the capacity of its European recycling facility, enabling more post-consumer carpet tiles to be processed and reintroduced into new products.

The results

Interface is now over halfway to meeting its 2030 science-based targets. It has achieved a 42% reduction in Scope 3 emissions from purchased goods and services since its 2019 baseline, increased the use of recycled and bio-based materials to around 51% of total inputs, and now offers more than 450 carbon negative cradle-to-gate ranges globally.

Since 2019, it has cut the carbon footprint of its three major product categories, with a 40% reduction in carpet tile emissions, 24% in rubber flooring and 45% in LVT and other resilient flooring, driven by cleaner energy, lower-carbon materials and a design philosophy that prioritises circularity and carbon storage. Its factories now run on 79% renewable energy, and the company continues to reduce water use, waste and energy intensity year on year.

The ReEntry programme has reclaimed over 96.2 million pounds of used carpet globally, with 11.7 million pounds of post-consumer carpet collected and diverted from landfill in 2025.

Runners up

Boots

Reducing the Impact of our Operations and Products

Boots has rebuilt the way it manages carbon, moving from annual reporting to quarterly tracking through carbon footprinting software with forecasting and scenario modelling. The retailer reports a 13% reduction in Scope 1 and 2 emissions between FY24 and FY25, driven mainly by energy work across its store estate including LED re-lamping. For its value chain, which accounts for most of its footprint, Boots has launched a Scope 3 Carbon Tool giving suppliers guidance and funding routes, and is writing carbon commitments into Joint Business Plans with major suppliers. Near-term and net-zero targets are being finalised for submission to the Science Based Targets initiative.

British Antarctic Survey

Towards Net-Zero

The British Antarctic Survey, part of UK Research and Innovation, is cutting emissions across operations running from Cambridge to Antarctic research stations, where remoteness, weather, safety requirements and short resupply windows constrain what can be changed. Its strategy covers Scope 1, 2 and material Scope 3 emissions across five pillars, overseen by three working groups reporting to a Net Zero Strategy Group. Solar now supplies 30-40% of Cambridge electricity demand and headquarters emissions have fallen 74%. Solar and battery systems have halved annual emissions at Bird Island, and hydropower meets 80% of demand at King Edward Point. Emissions fell 19% last year.

Consilient Health

Decarbonising by Design: Net-Zero Strategy for a Fully Outsourced Pharmaceutical Value Chain

Consilient Health is a mid-sized pharmaceutical company that outsources manufacturing, packaging, testing, storage and distribution, leaving more than 99% of its emissions in Scope 3 and outside its direct control. Regulatory requirements covering marketing authorisations, stability and batch release narrow the options further. Its strategy therefore rests on governance, supplier engagement and logistics redesign rather than asset upgrades, with targets validated by the Science Based Targets initiative. Total market-based emissions fell 44% in 2024, from 8,295 to 4,655 tCO2e, and upstream transport and distribution fell 94%.

NatWest Group

Project Planet

NatWest Group's Project Planet pairs operational emissions cuts with work to improve the quality of its supply chain data. A multi-year LED retrofit across the bank's property portfolio has reduced electricity demand by an average of 62%, saving 7.6GWh a year, while optimisation of building management systems at more than 20 large offices has delivered cumulative savings of 31GWh. Low-energy air curtains installed across 14 branches cut energy use by over 90%. Two corporate power purchase agreements supply 100GWh of solar electricity annually. For Scope 3, NatWest has increased its use of supplier-specific emissions data, reducing reliance on industry averages.

RELX

Data-Driven Net Zero Transformation

RELX, the information and analytics group, has cut Scope 1 and 2 emissions by 87% since 2010 through a switch to renewable electricity across its global operations, building efficiency improvements and reduced fuel use. The company holds targets validated by the Science Based Targets initiative and aligned to a 1.5C pathway, with net-zero committed for 2040. An internal carbon price, currently $60 per tonne of CO2, shapes investment decisions, while a CO2 Hub gives staff visibility of emissions data down to individual level. Governance runs through a Carbon Governance Group, with the chief financial officer acting as chief environmental champion.
