Emissions accounting
Sector GHG Contribution
This sector accounts for 0.4% of global greenhouse gas
emissions. This is the causal input that modulates transition pressure in the climate model above —
higher-emitting sectors face larger regulatory and market transition obligations under any pathway.

Primary emission sources:
diesel traction on non-electrified lines · maintenance facility heating
Rail is already the cleanest commercial freight mode at 3–8 gCO2e per tonne-km vs 20–40 for road. EU target 100% electrified by 2050. ~41% of global route-km already electrified. Transition costs are electrification capex for remaining diesel lines. Orderly transition reflects public infrastructure investment supporting grid decarbonisation, lowering traction emissions.

Carbon intensity
Scope 1 Intensity per $bn Revenue
Thousand tonnes CO₂e per billion USD revenue — the operational carbon cost of generating $1bn of
sector revenue. Lower is better. Colour = decarbonisation pace.
Supply-chain footprint
Scope 3 (Value-Chain) Emissions
Estimated Scope 3 emissions — upstream supply chain, sold-product end use, and downstream
processing. Company disclosures or IPCC Tier 2 estimates. Note the order-of-magnitude gap
between fossil producers and clean-energy companies.
Emissions intensity — pathway convergence
GHG Intensity per Unit of GDP — 2025–2045
Combined energy and carbon intensity index (base = 100 in 2025), derived from
the Kaya identity: EI index × CI index ÷ 100.
Faster convergence toward zero = stronger decoupling of output from emissions.
Source: CE Kaya decomposition calibrated to IPCC AR6 WG3 Ch. 3 & IEA NZE 2050.
Accelerated Transition achieves the steepest intensity reduction.
The gap between pathways by 2045 represents avoided emissions risk.

For rail in North America, climate stress matters economically through operations, financing, and supplier reliability rather than through a single aggregate damage number.
Facility disruption
Flood and heat events slow throughput while labor tightness and energy costs reduce utilization.
Impact score0.74
Affectsthroughput, downtime, labor productivity
Supplier fragility
Trade fragmentation and localized climate shocks increase inventory and lead-time volatility.

Priority
Prioritise green hydrogen pathway feasibility studies for high-temperature process heat.
Priority
Reprice capex hurdle rates to reflect carbon-cost pass-through under $150/tCO₂.
Priority
Accelerate supply-chain reshoring to reduce exposure to climate-fragile logistics corridors.
Watch
CBAM certificate costs materially affecting competitiveness
Watch
Forced asset idling from acute extreme-weather events
Watch
Stranded-asset risk in fossil-fuel-dependent process equipment
Watch
Near-term regulatory announcement risk (COP outcomes, domestic carbon-price reviews)
