  Description of the supply chain		 Sustainable supply chain
Tarmac has a supply chain of around 5,500 vendors procuring products, services and constituent materials. Of the products, services and materials we buy, 98% of our spend is with UK suppliers, with the majority of materials sourced through our own internal, vertical supply chain. The remaining <2% of our procurement is spent with suppliers outside of the UK.

Constituent materials include aggregates, cement, bitumen and mixtures. Services include plant maintenance, welding and construction services; products include energy (electricity, coal, gas and liquid fuels), heavy plant and construction equipment etc.

All our products are certified as responsibly sourced to BES 6001 and constituent materials are traceable to source. Procurement category managers have aligned their procurement processes to ISO 20400:2017 Sustainable Procurement Standard.

G4-EN1 Materials used by weight or volume

Circular economy
Total volume of materials from non-renewable source = 47.7 million tonnes (this figure includes primary aggregates, cement and lime)

Total volume of renewable materials during period = 7.1 million tonnes (this figure includes recycled construction demolition waste, use of recycled and secondary aggregates, e.g. recycled asphalt planning, slag aggregates and waste-derived fuels)
G4-EN2 Percentage of materials used that are recycled input materials Climate action
Circular economy
The percentage of recycled materials in our products can vary between 0% to 100%. This is largely dependent on customer specification.

Aspect: Water
G4-DMA Disclosure on management approach Circular economy
Our sustainability strategy
G4-EN8 Total water withdrawal by source Circular economy
G4-EN9 Water sources significantly affected by water withdrawal Circular economy
Water abstraction is a regulated process, governed by a licence granted by the relevant environmental regulator. Sustainability of the source is checked before granting the licence to abstract. There are no water bodies at risk from our operations or abstraction.
G4-EN10 Percentage and total volume of water recycled and reused Circular economy
A significant percentage of the water abstracted is simply moved from one place to another and not used. We capture rainwater for recycling in ponds and lagoons on site and this accounts for approximately 59.29% of our overall water consumption.
Aspect: Biodiversity
G4-DMA Disclosure on management approach Environmental stewardship
Our sustainability strategy
G4-EN11 Operational sites owned, leased, managed in, or adjacent to, protected areas and areas of high biodiversity value outside protected areas. Environmental stewardship
We have 88 operational locations that are within or adjacent to (i.e. within 500m) areas that are sensitive sites or sites of high biodiversity subject to UK designated status. The sites are identified at a local level and are covered by site biodiversity management plans and planning permissions etc. Designated sites include: Sites of Special Scientific Interest (SSSI), Special Areas of Conservation (SACs), National Parks, Special Protection Areas (SPAs), RAMSAR Sites, National Nature Reserves (NNRs), Local Nature Reserves (LNRs) and Areas of Outstanding Natural Beauty (AONB).

G4-EN23 Total weight of waste by type and disposal method Circular economy
Waste disposal figures are provided by site staff. The method of disposal is determined by the location of the site and opportunities for recycling in the area etc. Much of our waste is recycled back into the products we manufacture. We are also working with our waste management contractors to look at ways to achieve our zero waste to landfill commitment.

Aspect: Supplier environmental assessment
G4-DMA Disclosure on management approach Responsible supply chain
We have a CRH Business Code of Conduct and a Supplier Code of Conduct which aim to promote ‘fair trading’. All products and services required by the business are tendered openly and suppliers are required to meet specific performance requirements, e.g. safety and health, and environmental. Tenders are managed by a Category Manager who holds regular meetings with the supplier during the contract period. We are a partner of the supply chain sustainability school which promotes sustainable business practices within the UK construction sector. As part of our transition to ISO 20400 a ‘heat map’ exercise (risk assessment) is carried out on all product categories. This process helps to identify potential negative impacts. Negative impacts are considered as part of the decision to award contracts and are discussed with suppliers as part of the supplier relationship management process. Once a contract is awarded the Category Manager reviews performance (including feedback from the site team) at regular intervals, and meets with the supplier to discuss these. For potential negative issues, an improvement plan will be developed and reviewed at the next meeting with the Category Manager. Failure to make improvements or meet Tarmac requirements, including those in our Code of Conduct, may result in the contract being terminated – this will be at the discretion of the Category Manager in discussion with the Director of Procurement.
