IETF rates for automotive manufacturing processes
Body pressing and stamping: 20-30%. Paint and surface treatment (e-coat, primer, topcoat cure ovens): 30-40% — highest IETF rate in automotive due to oven energy intensity. Casting and forging (powertrain, structural): 25-35%. CNC precision machining (engine blocks, gearboxes): 20-30%. Plastic injection moulding: 20-25%. Seating and trim assembly: 15-20%. EV battery pack assembly (new Phase 3/4 qualifying category): 20-30%. Composite body panels: 30-40%.
JLR Reimagine: Scope 3 supply chain requirements
JLR Reimagine: carbon neutral 2039, net zero supply chain 2050. Near-term: verified renewable energy from all tier-1 and key tier-2 suppliers by 2025 (already active); Scope 3 Category 1 decarbonisation pathway by 2027. 1,200+ West Midlands tier-1/tier-2 suppliers targeted. We deliver JLR-format Scope 3 audit packs aligned to the Reimagine supply chain data portal.
BMW i Commitment, Toyota and Stellantis
BMW Group i Commitment: verified renewable energy at key supply chain sites (OX4 Oxford, GU4, Midlands). Toyota Burnaston (DE1 — 180,000 vehicles/yr): 2035 carbon neutral target + Supplier Sustainability Guidelines requiring renewable energy adoption from tier-1 suppliers since 2024. Stellantis Dare Forward 2030: Vauxhall Luton (LU) and Ellesmere Port (CH — electric van) supply chains. EV van supply chain (body presses, battery systems, electrical components) qualifies for IETF EV battery manufacturing category.
JIT supply chain: installation without disruption
Automotive JIT and JIS suppliers have zero tolerance for production disruption. Our automotive installation methodology: timeline coordinated with production planning team; roof installation in Q2/Q3 off-peak; commissioning window (4-8 hours grid sync) pre-approved against shutdown schedule; no overhead work above moving production lines; strict tool inventory (BS EN ISO 14001 compliant). Zero lost-production incidents on all our automotive tier-1 installations.
Common questions
What IETF rate applies to automotive paint shop operations?
Paint and surface treatment (e-coat primer, topcoat, clearcoat cure ovens) qualifies for IETF Phase 3/4 at 30-40% — among the highest IETF rates in manufacturing. Paint cure ovens (180-220°C continuous) are among the UK's most energy-intensive single manufacturing processes. We assess paint line IETF eligibility at free desk feasibility.
Can solar be installed without disrupting JIT production?
Yes — we have delivered automotive tier-1/tier-2 installs at JIT suppliers with zero lost-production incidents. All roof work coordinated against production schedule in advance. Grid synchronisation (4-8 hours) scheduled against planned maintenance shutdown or weekend halt.
