Sustainability
A supply chain accountable at every link
Sustainability at BASE is applied where we have real influence — in the partners we choose, the communities connected to our supply network, and the standards we hold both to. Because we don't operate extraction sites ourselves, our sustainability commitments are expressed through supplier selection and ongoing review, not through operational programmes we run directly.
Environmental Awareness
Partnering only with responsible producers
Because BASE does not operate mines or quarries directly, our greatest environmental influence is in who we choose to work with — and how consistently we hold them to standard, long after the first contract is signed. A supplier's environmental record is reviewed with the same rigour as their production capacity, because both determine whether they stay in our network.
Our Commitments
Environmental screening
Every new supplier is reviewed for environmental permits and compliance history before partnership. A clean history is a condition of onboarding, not a preference. A supplier who can't produce clean permitting history doesn't get a provisional entry into our network while they sort it out.
Preference for efficiency
We favour producers who demonstrably minimise waste, water use and emissions. Where two suppliers meet the same specification, environmental performance is part of how we choose between them. Over time, this preference has shaped which producers we return to for repeat volume, not just which ones we onboard first.
Rehabilitation expectations
Quarry and mine partners are expected to maintain active land rehabilitation programmes. This is reviewed as part of our regular supplier assessment, not taken on trust. We ask for evidence, not assurance — site visits and documentation, not a line in a supplier's marketing material.
We can't control an extraction site directly — so we choose partners who run theirs the way we'd expect. It's an indirect form of control, but a real one — exercised through who gets our business and who doesn't. It's not the only lever available to a company our size, but it's the one we actually control.
Local Employment
Strengthening the regions we source from
Our supply network runs through specific quarries, mines and processing sites — and the communities around them. We prioritise partners who invest in local employment and skills, because a stable local workforce is also what keeps our supply consistent.
Our Commitments
Local hiring preference
We favour supplier partners who prioritise hiring and training from their local communities. It's a factor we weigh alongside price and capacity, not an afterthought. It's also, practically, good business — a local workforce with a stake in the operation's future tends to produce more consistent output.
Skills development
Where possible, we support partner initiatives that build technical skills locally. A more skilled local workforce also means fewer quality issues downstream. Some of our longest-standing partners started as smaller operations we watched grow alongside a more skilled local team.
Long-term partnerships
Multi-year supplier relationships give local operations the stability to plan and invest — in equipment, in training, and in their own workforce. That stability compounds — a supplier confident in next year's demand invests differently than one negotiating contract to contract.
Stable local employment and stable supply tend to go together — we look for both. Neither is something we can mandate directly, but both are something we can consistently favour. Over enough contracts, that preference adds up to something a purely price-driven buyer would never build on their own.
Social Responsibility
Investing beyond the transaction
BASE's supply network connects us to communities across Türkiye and Russia. We look for ways to contribute to those communities beyond the material we purchase from them, treating that connection as a responsibility rather than a byproduct of doing business.
Our Commitments
Community engagement
We support supplier-led community initiatives in the regions our materials originate from. These are identified by our partners on the ground, not designed remotely from a head office. We fund and support what local partners identify as genuine needs, rather than exporting a standard programme that looks the same in every region.
Fair supplier terms
Payment terms and pricing are structured to support the long-term stability of our partners. A supplier squeezed on price today is a supply risk tomorrow. Slow payment or aggressive renegotiation might save money in a single quarter, but it's the kind of pressure that erodes a supply relationship over years.
Responsible growth
We expand our sourcing network in ways that benefit source communities, not only export volumes. Growth that only benefits BASE isn't growth we pursue. We'll pass on a volume increase if the only way to deliver it puts pressure on a source community rather than benefiting it.
The communities we source from are part of the supply chain, not separate from it. That framing shapes decisions well before they ever reach a page like this one. It's a quieter commitment than a press release, but it's the one that's still true a year later.
