Resource efficiency and climate change

Transition to a low carbon and more efficient business and deliver zero carbon ready homes


Reducing our impact on the environment meets legal requirements, contributes to the wider need to achieve net zero carbon and maintains our standing with stakeholders.

Sustainability on site

  • Our strategy is to achieve decarbonisation across the whole of our value chain, while ensuring we’re resilient and adaptive to a changing climate.


Our commitment is to achieve net zero greenhouse gas (GHG) emissions no later than 2050.  Working  with the Carbon Trust, we have set near-term targets against a 2021 baseline. These have been validated by the Science Based Targets initiative.  


We have set our target to achieve net zero carbon by 2045, building on our previous commitment to achieve net zero carbon before 2050. This target has been submitted to the Science Based Target initiative for verification and will sit alongside our approved carbon reduction targets for 2030. 

Our approved near-term science-based targets.

  • Reduce absolute scope 1 and scope 2 emissions 42% by FY2030 from a baseline year FY2021.

  • Reduce absolute scope 3 emissions 25% by FY2030 from a baseline year FY2021.

Carbon data and disclosures


We have been disclosing our carbon emissions and reduction activities to the Carbon Disclosure Project (CDP) annually since 2010. In the most recent submission we were awarded a B grade. Our CDP questionnaire provides more detail on our climate-related risks and opportunities and how these are managed within the business.

CDP questionnaire

We report climate-related disclosures following the TCFD’s recommendations and have structured our responses around the four key thematic areas. Our TCFD report examines a range of possible climate scenarios and the impact of each on Redrow’s business. Our long-term strategy embeds these impacts into governance and processes to ensure a strategic response and practical implementation to prepare the business for a changing world.

Carbon reduction initiatives

We have developed a suite of initiatives that are designed to reduce our carbon emissions, and are already working on delivering many of these across our business and with our partners. However, we also continuously review new technologies or processes that will help further, both with our Scope 1 and 2 target and our Scope 3 target.

  • Electric cars logoElectric company cars

    We have set a target to reach an all-electric car fleet by the end of FY25.  By 2023, there will only be electric vehicles available for selection on the company car list (1,230 tCO2e).

    HVO fuel logoHVO fuel

    HVO is a biodegradable non-toxic fuel that is produced from vegetable fats and oils and can be used as an alternative to mineral diesel. By switching to HVO for our site machinery and generators, we can achieve significant carbon reductions. In FY2022 we used 97,102 litres of HVO which resulted in saving 264 tonnes of CO2e that would otherwise have been emitted in to the atmosphere. This is a reduction in carbon emissions of 98% and the calculation is based on the UK Government’s DEFRA 2022 conversion factors for calculating greenhouse gas emissions.

    Renewable electricity logoRenewable electricity

    We have set a target for 100% of our operational electricity will sourced from renewable sources, backed by Renewable Energy Guarantees of Origin (REGO) certificates. New contracts have been established in FY22 (5,216 tCO2e – sites)  (415 tCO2e - offices).

    Heating and lighting logoHeating and lighting

    New modular compounds introduced in FY22 offer more carbon and energy efficient  site accommodation. Additionally the introduction of a ‘switch – off’ initiatives across our customer experience suites, show homes  and homes nearing completion will further contribute to reductions (132tCO2e + 10TCO2e).  

    Identified improvements recommended as part of the ESOS report (2019) have been costed and scheduled in as part of the wider Redrow Office upgrade planned over the upcoming years.

    PV panels logoPV panels

    Costing and payback exercise undertaken identified that the installation of PV panels at Redrow’s  Head Office, St David’s Park will offer significant carbon reductions and a cost neutral benefit within 7 years (50 tCO2e).

    Diesel emissions reduction logoDiesel emissions reduction

    We are working with our construction and commercial teams to connect our site accommodation and homes to the national grid as early as possible to reduce the need for diesel generators.  By monitoring and reporting on average site connection time we are able to identify trends and good practice (10 tCO2e approx.)

    Fuel efficiency logoFuel efficiency

    Behavioural change campaign planned explaining the impact of leaving machinery idle rather than ‘turning it off’ will be undertaken in the upcoming years. Predominantly targeted at ground workers and machinery operators (10 tCO2e approx.)  

    Solar generators logoSolar generators

    In FY23 we plan to undertaken further trails of solar generators on our site to identify the cost version carbon / energy savings (10 tCO2e).

  • FHS logoImplement Future Homes Standard (FHS) 2025

    Our ‘homes in use’ contribute 50% of our Scope 3 emissions, the impact of the 2025 FHS building regulations will significantly contribute toward reducing this.

    As of January 2023, homes on all our upcoming developments will be heated using air source heat pumps. This is our commitment 2 years in advance of the FHS regulations. And will reduce the carbon emissions from our homes by 70 – 80% compared with our previous house design.

    Every site and plot we complete ahead of building regulations will help guarantee we reduce our scope 3 emissions by 22% and meet our 2030 target.

    supply chain logoSupport our supply chain with setting own NZC targets

    Our scope 3 emissions are heavily reliant on our supply chain’s own emissions, target setting and carbon reduction plans.

    By understanding where our supply chain are, on their own NZC journey and how they plan to reduce their carbon emissions, our carbon experts can offer advice, support and facilitate carbon related training.

    EPD database logoEstablish an EPD database for our key carbon contributors

    We are working with our key carbon contributors to better understand the products we use to build our homes.

    Environmental Product Declaration (EPD) provide us with information about a product's impact upon the environment based on it’s life cycle assessment. This will allow us to compare different materials and products in order to help us select the most sustainable options.

    Carbon related causes logoCarbon related causes within commercial contracts

    As part of the onboarding process, there will be an expectation that our preferred suppliers and subcontractors will set science-based emission reduction targets in line with SBTi resources, or equivalent, within 5 years.

    industry product associations logoEngage with industry product associations

    Product related emissions account for nearly 38% of our total Scope 3 emissions.

    Transformational change in the materials and products we buy; how they are designed, manufactured and distributed; and their raw-material composition needs focus on lower carbon emissions.

    Becoming net zero by 2050 is an industry wide priority by partnering with product associations we can create a bigger impact.

    Improve data accuracy logoImprove data accuracy

    Use the GHG protocol to ensure consistency in data collection and report using transparent tCO2e across all reporting categories.

    Higher certainty in supply chain data will improve Redrow’s ability to drive and track reductions.

    Collaborate logoCollaborate with Supply Chain Sustainability School & Future Homes Hub

    Working with our industry peers and supply chain via the Supply Chain Sustainability School and the Future Homes Hub working groups we are sharing best practice and R&D to guarantee our industry is moving toward Net Zero Carbon no later than 2050.

Low carbon homes 

We have undertaken Life Cycle Analysis to understand the carbon footprint of our homes, resulting in better visibility of how to reduce the carbon footprint of each home we build. 


Ahead of the government’s proposals to decarbonise new-build homes from 2025 (part of the Future Homes Standard), we were the first large homebuilder to incorporate ASHPs and underfloor heating as standard in Redrow houses.

Promoting supply chain sustainability

We are partners in the Supply Chain Sustainability School, which is an award-winning initiative providing free learning and development to help our supply chain partners address sustainability issues. The School offers free practical support to all Redrow suppliers and subcontractors in the form of e-learning modules, training workshops and self-assessments. Since we became partners with the school, over 4,700 free resources have been accessed by more than 300 Redrow suppliers. We encourage our supply chain to improve their knowledge and understanding of sustainability issues through the School's programmes and also sit on the Homes Leadership Group and Carbon and Waste Special Interest Groups, supporting the development of the School.

Solar PV panels

We offer customers the opportunity to upgrade their homes by adding solar PV panels through MyRedrow, our online sales system. This reduces the customer's reliance on grid electricity and reduces their utility bills. It also improves the home’s EPC rating, which is a score relating to the cost of energy needed to run a particular home, while reducing CO2 emissions. The average EPC rating for our homes is B, but the integration of solar PV can improve this to an A rating.

Enhancing efficiencies and conserving natural resources

Our programmes to reduce waste, improve water efficiency, and source timber responsibly has helped to not only reduce costs, but also our upstream and downstream impacts on the environment.

Waste management

Our waste strategy has been developed around three key phases of waste reduction in our processes: design, supply chain management and site operations. 

Reduce the Rubble signage

Our award winning Reduce the Rubble research project sought to drill-down and identify every component of the waste generated during our build process. The research helped us to better understand the root-causes of waste and identify how it might either be eliminated, reduced or re-used.

Sustainable earthworks project at Daresbury Garden Village

During 2024, we collaborated with Ecofill at our Daresbury Garden Village development in Warrington. Ecofill's groundbreaking technology was used to transform on-site clays and subsoils into aggregate replacement products, meeting all National and European specifications for Highways and Earthworks. This innovative approach significantly reduces the export of soils to landfill and the import of aggregates, thereby drastically cutting lorry movements, carbon emissions, and construction costs. By leveraging Ecofill's technology, we were able to divert approximately 18,559 tonnes from landfill, saving 21,343 tonnes of imported aggregate, reducing 4,158 lorry movements, and eliminating 147 tonnes of carbon emissions.


Chris Hayton, Technical Project Manager at Redrow North West, expressed enthusiasm for integrating Ecofill's innovative technology into the project. "Ecofill's solution aligns perfectly with our sustainability goals for Daresbury Garden Village," said Hayton. "Their expertise in transforming on-site materials not only enhances the environmental sustainability of our construction but also demonstrates our dedication to innovation and cutting-edge technology."

Community wood recycling

We work in partnership with the Community Wood Recycling Schemes to recycle and recover waste timber from our sites. The Community Wood Recycling Scheme is a national network which provides a collection service for excess wood, with the aim of saving resources by reusing and recycling waste timber. The Scheme also operates as a social enterprise, creating opportunities for local people.

Our Sustainable Timber Procurement Policy commits us and our supply chain to only source certified timber from sustainably managed forests, through Forest Stewardship Council (FSC) and The Programme for the Endorsement of Forest Certification (PEFC) schemes. Operations managed to FSC standards protect the trees, habitats, biodiversity and the local people from corruptive dealership and landownership.

Although water isn’t currently rated as a significant material issue for the majority of Redrow stakeholders, each year risks associated with water availability and quality become more acute. These range from pressures on water conservation and neutrality, to business continuity risks posed by supply interruptions and reputational issues arising from rising home water bills. Extreme heat and lower rainfall in the summer will result in further impacts on water stressed areas.

  • We also incorporate Sustainable Urban Drainage schemes (SUDS) on the majority of our developments to improve rainwater management and reduce flood risk. SUDS Systems are designed to mimic the natural drainage of surface water by managing rainfall, whilst also often providing habitats for wildlife.

  • In our operations, we look to reduce water use wherever possible from more water efficient site cabins to using recycled water for wheel washes. Our total water use has reduced in the last 12 months.

  • Our homes are industry-leading in terms of water efficiency, with a rating of just 105 litres per person per day, well below the Building Regulations requirement of 125 l/p/d. We achieve this with highly efficient fixtures, water saving baths and flow restrictors.

  • Achieving water neutrality is an important consideration in areas of high water stress. We are exploring ways to improve our water efficiency further through research and partnership to contribute to the goal of water neutrality. For example, we’ve joined multi-stakeholder forums to collaborate on water efficiency and water neutrality solutions including collaborating with the industry through the Future Homes Hub.

  • We’re committed to playing our part in tackling high nitrate and phosphate content in rivers and coastal water. At our developments in sensitive river catchment areas, we’ve been working hard to find innovative solutions, such as replacing low-value agricultural land with biodiverse green infrastructure, creating wetlands and building on-development wastewater treatment works.
