What is a fleet’s carbon footprint?

Definition and measurement scope

A fleet’s carbon footprint represents the total amount of greenhouse gases emitted by all company vehicles, measured in CO₂ equivalents (CO₂e). In practice, it accounts for all pollutants generated by your fleet—from manufacturing to recycling. This calculation method helps optimize fleet management and reduce the environmental impact of business travel.

The calculation is based on three scopes defined by the Greenhouse Gas Protocol:

Scope 1 – Direct emissions: Everything that comes out of your combustion vehicles’ exhaust pipes. Every liter of fuel burned generates CO₂ that your company directly controls. This is often the largest share of a traditional fleet’s footprint.
Scope 2 – Indirect energy emissions: Electricity used to charge electric vehicles. Emissions vary depending on the energy source—nuclear, renewables, or coal. Your choice of green energy supplier directly affects this category.
Scope 3 – Other indirect emissions: Everything else—vehicle manufacturing, transport to dealerships, fuel production, repairs, and end-of-life recycling. This category often accounts for 70% of a fleet’s total footprint.

Regulatory context: new obligations for companies

Regulation	Scope	Obligations	Deadlines
CSRD	Companies >250 employees or >€40M turnover	Detailed transport emissions reporting	Since 2024
LOM Law	Private fleets >50 vehicles	10% clean vehicles	Immediate
	Public fleets	20% clean vehicles	Immediate
	All fleets	35% clean vehicles	By 2030
ZFE-m	11 French metropolitan areas	Restrictions on polluting vehicles	Progressive

These regulatory changes make fleet decarbonization a legal obligation.

Why is it beneficial to measure it?

Proactive regulatory compliance: Anticipating changes avoids future penalties and costly last-minute adaptations. It’s also a competitive edge.
Enhanced employer branding: Employees care about environmental commitment. According to ADEME, 65% of workers value their employer’s CSR actions. A clean fleet can attract and retain talent.
Significant operational savings: Contrary to popular belief, EVs can save money. Properly used, an EV costs up to 30% less over its lifecycle—thanks to fuel savings, simpler maintenance, and tax benefits.
Commercial differentiation: Clients increasingly consider carbon footprint. Public and private tenders now include environmental criteria. A clean fleet can tip the scales in your favor.
Easier financing access: Banks and investors now assess ESG criteria. A documented decarbonization strategy improves relationships and may lower financing costs.

How to calculate your carbon footprint?

The formula is simple:

Annual consumption (L or kWh) × Emission factor = CO₂ emissions (kg/year)

ADEME reference emission factors:

Diesel: 2.56 kg CO₂/l
Gasoline: 2.28 kg CO₂/l
LPG: 1.61 kg CO₂/l
Electricity (France): 0.059 kg CO₂/kWh
Electricity (EU average): 0.420 kg CO₂/kWh

Example:A salesperson drives 25,000 km/year in a diesel Peugeot 308 consuming 5.5 L/100 km. Annual consumption = 1,375 L.CO₂ emissions = 1,375 × 2.56 = 3,520 kg/year.

An electric Renault Zoé driving 12,000 km/year at 16 kWh/100 km uses 1,920 kWh.CO₂ emissions = 1,920 × 0.059 = 113 kg/year.

The difference is striking: the EV emits 30 times less CO₂ than the diesel.

To calculate your fleet’s total footprint, apply the formula to each vehicle and sum the results. A typical fleet of 5 vehicles (3 diesel, 2 electric) may emit nearly 10 tons of CO₂ annually—97% from combustion vehicles.

Environmental KPIs to track

Indicator	2025 Target	2030 Target	Calculation Method
Average emissions	< 110g CO₂/km	< 90g CO₂/km	Total CO₂ / km driven
EV share	> 25%	> 50%	EVs / Total fleet × 100
Annual reduction	> 5%	> 8%	(N-1 – N) / N-1 × 100
Eco-driving training	80% of drivers	100% of drivers	Trained / Total × 100

These KPIs help compare performance, identify high-emission vehicles, and measure the impact of actions taken.

What levers exist?

Usage and route optimization

Internal car-sharing reduces fleet size while maintaining service levels. Creating vehicle pools by site or department, with digital booking systems, improves utilization rates.

Modern geolocation tools avoid unnecessary detours and optimize routes in real time. Grouping deliveries and client visits, combined with remote work, directly reduces emissions.

Eco-driving training

Eco-driving cuts fuel use by 10–15% (ADEME). It also reduces mechanical wear and accident risk.

On-track training is most effective, supported by real-time telematics coaching. Internal challenges and mobile apps help maintain long-term driver engagement.

Predictive maintenance and technical optimization

Telematics monitoring anticipates maintenance needs before breakdowns. Automatic alerts for scheduled maintenance reduce downtime and improve fleet availability.

Low rolling resistance tires cut consumption by 3–5%. High-performance engine oils and regular air filter maintenance also help maintain energy efficiency.

Performance tracking and monitoring

Dashboards and real-time monitoring

Modern platforms track emissions per vehicle and driver in real time. Alerts for consumption spikes enable quick action, while goal comparisons keep teams motivated.

AI algorithms predict charging needs based on planned routes and driving habits. Automatic route optimization and predictive behavior analysis help anticipate issues and suggest corrective actions.

Reporting and communication

Monthly dashboards support strategic decision-making. Quarterly team updates maintain engagement and allow adjustments. Annual CSR reports showcase progress to stakeholders.

Regular updates on social media boost environmental brand image. Including results in sales materials becomes a differentiating argument. Third-party certification adds credibility for clients and investors.

Switching to electric: the most effective way to decarbonize your fleet

Field experience shows promising results. Fleets electrifying 30–40% of light vehicles see a 25–30% carbon footprint reduction in two years.

Savings are quick: €600–€1,000/year per EV, ROI in 18–24 months, and 40–50 tons of CO₂ saved annually for a 15-vehicle fleet.

Beyond numbers, companies report unexpected benefits: improved brand image, employee pride, and easier responses to RFPs with CSR criteria.

EVs save up to 2 tons of CO₂ per vehicle/year (ADEME). They emit 75% less over their full lifecycle, including battery production and electricity generation.

Government incentives make electrification financially attractive:

Tax Benefit	Amount	Conditions	Financial Impact
Ecological Bonus	Up to €7,000	New EV < €47,000	Lower purchase cost
TVS Exemption	100%	Electric vehicles	€1,000–€3,000/year saved
Over-depreciation	40%	Tax depreciation	Lower corporate tax
Electricity VAT	100% deductible	Professional charging	20% energy savings
