📋 Executive Summary

The Problem: "We Think We're Green — But We Don't Actually Know"

The company operated a fleet of 340 vehicles — trucks, vans, and motorcycles — serving last-mile and mid-haul logistics across a metro region. They had 6 facilities (3 warehouses, 2 sorting hubs, 1 head office) consuming electricity, diesel generators, and refrigeration. They also relied on third-party carriers for 30% of deliveries and purchased packaging materials, fuel, and equipment from a global supply chain.

Leadership wanted to publish an ESG report and set science-based reduction targets — but had never formally measured emissions. The sustainability team had attempted estimates using fuel purchase receipts and electricity bills, but the numbers were incomplete, inconsistent, and didn't follow GHG Protocol methodology. There was no Scope 3 assessment at all.

We conducted a comprehensive emissions audit across all three GHG Protocol scopes, built an emissions inventory database, and developed an interactive reduction pathway model that leadership could use to test different decarbonization strategies and their cost implications.

🌍 Finding #1

The Scope 1/2/3 Breakdown: Where 42,800 Tonnes Come From

The GHG Protocol divides emissions into three scopes. For this logistics company, the breakdown revealed a Scope 1-heavy profile — unusual for most industries but typical for fleet-dependent operations:

Scope 1 — Direct Emissions
24,200 tCO₂e
Fleet diesel, generator fuel, refrigerants
57%
Scope 2 — Purchased Energy
8,400 tCO₂e
Warehouse electricity, office power, EV charging
20%
Scope 3 — Value Chain
10,200 tCO₂e
3PL carriers, packaging, fuel production, commuting
24%

Emissions by Source Category

All scopes combined — top 10 sources

Monthly Emissions Trend (Baseline Year)

Total tCO₂e by scope per month

Key insight: Fleet diesel combustion (Scope 1) and warehouse electricity (Scope 2) together account for 72% of total emissions. This concentration is good news for reduction planning — two focused interventions can address nearly three-quarters of the footprint.

🚛 Finding #2

The Heavy Trucks Are 18% of the Fleet but 52% of Fleet Emissions

The 340-vehicle fleet breaks down into four categories. Heavy trucks — just 62 vehicles — produce 12,600 tCO₂e annually, more than the rest of the fleet combined. This is because heavy trucks have 4× the fuel consumption per kilometer and run 3× the daily distance of delivery vans.

🏭 Finding #3

One Warehouse Produces 40% of All Facility Emissions

The 6 facilities have dramatically different emission profiles. The central warehouse — the largest at 45,000 sqm with cold storage — consumes 3× more electricity than the next-largest facility. Its refrigeration system alone accounts for 2,800 tCO₂e, more than the head office and two sorting hubs combined.

Facility Energy Consumption by Source

Monthly MWh — electricity, diesel generators, and natural gas

Key insight: The central warehouse's refrigeration system uses R-404A refrigerant with a GWP of 3,922. Switching to a low-GWP alternative (R-449A, GWP 1,397) would reduce refrigerant-related emissions by 64% — a $120K investment that pays back in 2.8 years through reduced refrigerant purchase costs alone.

🔗 Finding #4

Third-Party Carriers Are the Largest Scope 3 Source — And Growing

The Scope 3 analysis revealed 10,200 tCO₂e from value chain activities. The biggest contributor: third-party carrier emissions at 4,100 tCO₂e (40% of Scope 3). As the company outsources more last-mile delivery to gig-economy partners, this category is growing 15% year-over-year — potentially offsetting Scope 1 reductions from fleet improvements.

The Reduction Roadmap: -38% by 2030 Without Replacing Trucks

The most important finding: a 38% emissions reduction is achievable through operational changes and targeted investments — without replacing the truck fleet. The roadmap prioritizes interventions by cost-effectiveness ($ per tCO₂e avoided):

Phase 1 — Quick Wins (2025)
Route Optimization & Eco-Driving Training
AI-powered route optimization reduces average km/delivery by 12%. Eco-driving training cuts fuel consumption by 8% per driver. Combined: 3,200 tCO₂e reduction.
↓ 3,200 tCO₂e · $18/tonne avoided · ROI: 14 months
Phase 1 — Quick Wins (2025)
LED Retrofit + Smart HVAC Controls
Full LED conversion across 6 facilities + smart thermostat installation. Reduces electricity consumption by 22% in warehouses and 35% in office spaces.
↓ 1,850 tCO₂e · $24/tonne avoided · ROI: 11 months
Phase 2 — Medium Term (2026–2027)
Rooftop Solar on 3 Warehouses
680 kWp total solar capacity across 3 warehouse rooftops. Generates 40% of annual electricity needs, eliminating 3,360 tCO₂e from grid power.
↓ 3,360 tCO₂e · $32/tonne avoided · ROI: 4.2 years
Phase 2 — Medium Term (2026–2027)
Refrigerant Transition (R-404A → R-449A)
Replace high-GWP refrigerant in the central warehouse cold chain. Drop-in replacement requiring minimal system modification.
↓ 1,800 tCO₂e · $67/tonne avoided · ROI: 2.8 years
Phase 3 — Strategic (2028–2030)
Electric Van Pilot (40 vehicles) + 3PL Carbon Requirements
Replace 40 light delivery vans with EVs (the most cost-effective fleet segment to electrify). Introduce carbon reporting requirements for top 10 3PL partners, targeting 20% reduction in outsourced delivery emissions.
↓ 5,940 tCO₂e · $45/tonne avoided · ROI: 5.1 years
