Key Insights & Forward Look

Strategic observations from the carbon intensity analysis

Natural Gas Dominance

Gas accounts for 56–57% of per-piece emissions and is dedicated entirely to vulcanisation. Any process efficiency gain — hybrid heating, improved insulation, optimisation — maps directly to carbon reduction with no allocation ambiguity.

Grid Decarbonisation Tailwind

Turkey's grid emission factor has declined from 0.44 to 0.375 kg CO₂e/kWh (2020–2024) and is projected to reach 0.33–0.35 by 2028. Scope 2 improves automatically; on-site solar installation would accelerate this further.

Utilisation Sensitivity

The +12% intensity increase reflects underutilisation, not efficiency loss. At full two-shift capacity, modelling projects approximately 2.0–2.5 kg CO₂/piece — a 37–45% reduction from current levels.

EU CBAM Readiness

Per-piece carbon accounting positions OESP to provide verifiable product-level emissions data to European customers under CBAM transitional reporting, using internationally recognised emission factors and GHG Protocol methodology.

Heat Recovery Advantage

Recycled vulcanisation water provides building space heating, eliminating a separate comfort-heating gas line. Reported gas intensity is purely process-related — a clean metric with no seasonal dilution.

Methodology & Emission Factors

Calculation Method

Emissions calculated using the activity-data method per GHG Protocol Corporate Standard. Monthly per-piece intensity = (Energy kWh × Emission Factor) ÷ Monthly vulcanised output (accepted + scrap + rework).

Natural Gas 0.20 kg CO₂ / kWh — IPCC 2006 (stationary combustion)
Electricity (Turkey Grid) 0.375 kg CO₂e / kWh — TEİAŞ 2024 grid average
Heavy Truck (>33t, laden) 0.917 kg CO₂e / vehicle-km — UK DEFRA 2024
Freight Route Bursa → Adıyaman, ~1,150 km per trip (FTL)
