We help large businesses get their suppliers acting on sustainability, and help suppliers keep winning work.
Ltt is a UK-based supply chain sustainability consultancy, working with large organisations and the suppliers they rely on.



We're working with suppliers of Marriott Hotels, HSBC, NHS England, Crown Commercial Services, Ministry of Defence, IHG, Laing O'Rourke, Morgan Sindall, TUI, Avant Homes, VW Group, Deutsche Bank, Virgin Atlantic, and EMR Rail to retain contracts and win new business.
Two ways in
For corporates
Get your suppliers to act on your sustainability requirements. We contact your suppliers, follow them up and send you a progress report every quarter, so your team doesn't have to chase them.
How we work with corporatesFor suppliers
Your customers are asking for EcoVadis scores, carbon figures and tender evidence you haven't had to provide before. We help you provide it properly, protect the work you already have and strengthen your position when the next contract comes up.
How we help suppliersHow we help suppliers
EcoVadis support.
Your customer wants an EcoVadis score. We explain what's being assessed, guide you through the assessment and help you use the result with customers.
Virtual Impact Teams.
When a customer request lands and you don't have the people to deal with it, a Virtual Impact Team handles the tender, carbon, social value or policy work for you.
Carbon assessment.
Measure your carbon footprint, with advice on using it in tenders and customer questionnaires.
Training.
Half-day and full-day courses on EcoVadis, sustainability in tenders and commercial sustainability.
Ltt Recruitment places specialist sustainability hires, and we work with specialist partners on social value.
