Sustainable Procurement Policy

Introduction
At the Howard de Walden Estate (HdWE), our mission is simple. We strive to enhance Marylebone’s community through responsible stewardship, we aim to offer excellent service to our customers, whilst ensuring the Estate remains a coveted place for generations to come. As long-term stewards of one of London’s most desirable neighbourhoods, sustainability sits at the very core of this mission.
In 2023, we launched our Sustainability Strategy, deCarbon, outlining the objectives and priorities we believe are essential for addressing climate change and safeguarding our long-term interests. deCarbon focuses primarily on our commitment to reduce carbon emissions but we also have a duty to act responsibly across a broader range of themes and sustainability-related issues. They all impact our purchasing decisions and the activity within our wider value chain, which this Policy aims to communicate by setting out our mandatory and preferred procurement requirements.
We believe that close alignment on these issues with our suppliers will help to strengthen our relationships and improve our overall success outcomes. Partnerships built on a shared sense of endeavour are essential to address the sustainability challenges within the built environment; and we believe this is good for business in the long term This is why we are prioritising partnerships with suppliers who take steps to align with our vision and can evidence their contribution to sustainable practices through the goods, works and services they provide
“Two thirds of our carbon emissions are generated from the goods, works and services we procure”
Policy overview
We consider our suppliers are an extension of our business and core to our own performance and reputation. The purpose of this Sustainable Procurement Policy is to outline the requirements we expect from the goods, works and/or services provided (directly or indirectly) by all suppliers to the HdWE
HdWE defines sustainable procurement as: Meeting our customers' needs by sourcing products and services that offer the best quality and value, and by considering the environmental, social, and ethical impacts throughout the entire product or service lifecycle. All suppliers should read this policy in conjunction with both the Supplier Code of Conduct and our Standard Terms & Conditions. Please note that suppliers appointed under Construction Contracts (typically those concerned with Section 3 of this Policy) are exempted from our Standard Terms & Conditions, as these contracts are subject to other terms.
The themes addressed within this policy include carbon reduction, resource efficiency and waste, responsible sourcing and materials, environmental protection, climate resilience, biodiversity, and social value These themes feature across all five Sections of this policy, structured as follows:
• Section 1: Universal requirements
• Section 2: Managing our buildings
• Section 3: Delivering refurbishments and redevelopments
• Section 4: Marketing, communications and events
• Section 5: Head office (23 Queen Anne St)
The policy clarifies the relevance of each section at the outset and provides a general overview of the types of suppliers it may relate to, which is not exhaustive. However, suppliers are encouraged to review the full context and content of this policy as the applicability of individual requirements can vary depending on the type of work being procured
We have highlighted our mandatory requirements in red at the beginning of each section, which must be met when they relate to the goods, works and/or services being procured, or when requested through contracts, agreements and other engagements Preferential requirements are not highlighted in red, and whilst not
mandatory, are considered best practice and we encourage suppliers to adopt these requirements where possible, either now or at some point in the future
Responsibilities and evidence
This policy applies to both internal HdWE colleagues responsible for purchasing or specifying goods, works and/or services as well as existing and future suppliers working directly or indirectly on behalf of HdWE. In this policy, the term "supplier" refers to any provider of materials, products, works, or other services, including professional service providers When stipulated, our requirements extend to the supply chain of any supplier working on their/our behalf.
Our colleagues are expected to consider sustainability in every purchasing decision and actively manage compliance with this policy throughout the contracting and delivery stages. Evidence should be provided when requested to help demonstrate the level of compliance required. This should be relevant and proportionate to the goods, works and/or services being provided.
There are a small number of situations where suppliers may be exempted from this policy and our onboarding requirements. Such scenarios may include instances where HdWE has no choice in relation to how our affairs are conducted (e.g. central and local government, other national or local authorities, court and tribunal appointed entities, etc).
Commitment to our suppliers
Howard de Walden is committed to:
• Helping suppliers continually improve through a culture of transparency and collaboration
• Working with suppliers to help them reduce carbon emissions within their own operations
• Prioritising suppliers and prospective suppliers who can demonstrate they have embedded, or are working towards embedding, the requirements of this policy
• Maintaining our standard payment terms of 30 days
• Working with suppliers that uphold our corporate values and can support the delivery of our sustainability objectives
• Seeking feedback from suppliers to help improve our performance
• Measuring, reducing, and disclosing our own carbon emissions on an annual basis
“Our supply chain partners will demonstrate their commitment to sustainability”

Helpful resources
Supply chain sustainability school
The Supply Chain Sustainability School is a collaboration between companies aiming to enhance sustainability practices within their organisations and their supply chains. Organisations can access the school's extensive free guidance, resources, and CPD-accredited training materials. HdWE strongly encourages its supply chain partners to sign up and utilise relevant resources (particularly contractors and sub-contractors working on our refurbishment and redevelopment projects) More information and free resources are available on the Supply Chain Sustainability School's website.
Science Based Target initiative
The Science Based Target initiative (SBTi) helps companies set ambitious climate goals in line with the latest climate science to reduce greenhouse gas emissions and limit global warming to well below 2°C above preindustrial levels. It works by providing a clearly defined pathway for organisations to set science-based emissions reduction targets, which are then independently assessed and validated by the initiative. HdWE has set a Net Zero Commitment of 2040, aligned to the Science Base Target initiative and encourages its supply chain partners to do the same More information is available on the Science Based Target initiative website.
Westminster’s Sustainable City Charter
The purpose of the Sustainable City Charter is to encourage local authorities, businesses, and organisations to work together to make Westminster sustainable. The Charter aims to achieve this by setting out a series of commitments and actions that signatories should take to reduce their environmental impact, promote social equality, and improve economic prosperity. The Charter is seen as a key step in ensuring Westminster becomes net zero by 2040. HdWE became a signatory of the Charter in 2023, and this policy addresses the requirements under the ‘procurement and purchasing’ principle of the framework For more information please visit the following website Sustainable City Charter

Appendix A: HdWE Material Schedule
REQUIRED
Suppliers:
Prefer suppliers who have: ISO 14001:2015 certification
Cradle to Cradle certifications
Take-back schemes for surplus materials or offcuts
Reusable packaging solutions
Responsible Sourcing:
BES 6001 Very Good or Excellent for plasterboard, window glass, aggregates, concrete, cement, asphalt, blockwork and rebar
All materials to be extracted within Europe
Prefer products with verified Environmental Product Declarations/Lifecycle Carbon Assessments
Prefer products that report full chemical inventory of ingredients
Recycled Content:
Prefer materials with recycled content
· 100% of loose aggregate (except where the specification cannot be met from a locally sourced recycled aggregate)
· 80% in blockwork
· 50% in insulation
· 90% in plasterboard
· 50% in carpet tiles
· 50% in concrete paving
· 40% in asphalt roads
Timber:
All timber to be certified as PEFC or FSC, ideally ‘grown in Britain’
Stone:
Natural stone extracted within Europe
Steel:
Procure steel with the following certifications:
Steel: UK CARES SCS or BES 6001
Reinforcement: UK CARES SCS or ECO Reinforcement
Note that if a recycled content above 35% is requested for structural steel sections, the UK steel industry is unable to meet these requirements, so steel for these projects tends to be sourced from the larger European suppliers.
Concrete:
Select concrete with high cement replacement content. CEM II (up to 35% cement replacement) and CEM III (up to 55% cement replacement) should be favoured in all cases over CEM I (0% cement replacement)
Consider carbon negative concrete (https://carbicrete.com)
Aggregates:
Prefer sustainable, recycled, and secondary aggregates
Aluminium:
Prefer a source/supplier that uses less carbon-intensive production methods. Select PPC finish over anodised, for embodied carbon savings and end of life opportunities (anodising changes the chemistry and makes it more expensive and complex to recycle)
All aluminium products should be free of SF6
Screed:
Prefer low carbon alternatives to traditional cement-based screed
https://www.gyvlon.co.uk/en/environmental-impacts https://cemfloor.co.uk/sustainability / http://www.ecoscreed.co.uk/products
Insulation:
Prefer less carbon intensive mineral wool over PIR/PUR
Low/zero formaldehyde binders
Select insulation suppliers who offer take back schemes for offcuts or over-orders
Refrigerant use in HVAC systems:
Reduce the volume of refrigerant used: apply passive design measures and reduce the size of the equipment
All refrigerants should aim to have a global warming potential (GWP) less than 1000
Ensure low leakage. Refrigerant should be 100% recovered at the end of the product life following proper management procedures
Indoor Air Quality:
Paints, coating, adhesives and sealants applied on site with zero Volatile Organic Compounds (VOCs)
Flooring, furniture and insulation (thermal and acoustic) with low or zero VOCs
Ensure wet materials (such as adhesives, wood preservatives and finishes, sealants, glazing compounds, paints and joint fillers) are installed and allowed to fully cure, prior to installation of adsorptive materials
Transport, store and protect absorbent materials, e.g. carpets, upholstery, furnishings, fabric wall coverings, acoustic ceiling panels, in original packaging or sealed polyethylene sheeting until time of installation
Appliances:
All appliances to be A+++ rated or other energy certification top rated appliances (e.g. Energy Star)
