Tesco's Net Zero Action Plan commits the business to net zero own operations by 2035 and supply chain net zero by 2050. Tesco's supplier programme — particularly the Climate Lead supplier tier — explicitly favours suppliers with verified on-site renewable energy. For UK warehouse operators in Tesco's supply chain (own RDCs, 3PL operators serving Tesco, food production and processing supplying Tesco own-brand and stocked products), solar PV with verified monitoring is increasingly important for contract retention and tender preference.
Tesco Net Zero Action Plan landscape
Tesco Net Zero Action Plan: own operations net zero 2035, supply chain net zero 2050. SBTi 1.5°C-aligned. Scope 3 supplier programme: Climate Lead tier (highest); Climate Active tier; Standard tier. Climate Lead suppliers receive preference in tender weighting, capacity allocation, and contract renewal terms. Tesco operates 23 UK distribution centres serving 3,800 stores — major own-RDC solar rollout in progress.
Tesco supplier programme requirements
Climate Lead tier requirements: Scope 1+2 net zero 2035 commitment; Scope 3 reduction trajectory; verified on-site renewable energy; SBTi-validated targets where applicable; supply chain transparency via CDP Supply Chain disclosure. Climate Active tier: subset of Climate Lead requirements. Standard tier: minimum compliance. Solar PV with verified monitoring is core evidence for Climate Lead status.

A national grocery retailer mid-sized RDC near Wakefield serving Northern stores. 320,000 sqft mixed ambient + chilled + frozen, owner-occupied. 1.4 MW PV install, 85% self-consumption. £287k/yr saving, 4.9yr payback. Featured in retailer's annual sustainability report and SBTi progress disclosure. Phase 2 across three further RDCs in commissioning.
Common questions about tesco supplier
How does Tesco's Climate Lead supplier tier work?
Climate Lead is the highest tier of Tesco's supplier sustainability programme. Requires Scope 1+2 net zero 2035 commitment, Scope 3 reduction trajectory, verified on-site renewables, SBTi-validated targets where applicable. Tier members receive preference in tender weighting, capacity allocation, and contract renewal terms.
What renewable evidence does Tesco accept?
Verified on-site generation (solar PV with monitoring) is highest-quality evidence. Our standard audit pack supplemented with Tesco-specific verification certificate covers all programme requirements. Renewable tariff purchasing has lower weight than on-site generation.
How does our solar contribute to Tesco's 2035 supply chain target?
Direct contribution. Your Scope 2 reduction (from solar) flows into Tesco's Scope 3 reduction calculation. The annual generation export and Scope 2 reduction quantification are inputs to Tesco's supplier programme reporting and SBTi progress disclosure.
