Scope 1, 2, 3 Emissions Explained: How Fleet Electrification Drives Carbon Emissions Reduction

For Canadian fleet managers, greenhouse gas reporting has moved from voluntary best practice to a boardroom priority. Scope 3 emissions reporting is accelerating as clients and investors demand visibility into the full value chain, and understanding this framework is now a core fleet management competency. The biggest lever available to most commercial fleets is also one of the most straightforward: electrifying your vehicles.

Scope 1, 2, 3 emissions classify a company's greenhouse gas output by source: Scope 1 covers direct emissions from owned vehicles and equipment, Scope 2 covers purchased energy, and Scope 3 covers indirect value chain emissions. For fleet managers, electrifying vehicles directly reduces Scope 1 and, with clean electricity, Scope 2 emissions as well.

1. Why Emissions Accounting Is Now a Fleet Management Responsibility

Canada's Greenhouse Gas Reporting Program has expanded, supply chain transparency demands have intensified, and ESG commitments from institutional investors are flowing down to mid-market operators.

Fleet managers in logistics, construction, and last-mile delivery are increasingly asked to provide emissions data by clients and procurement teams. Understanding where a company's emissions originate - and which scope they fall into - is the starting point for any credible carbon emissions reduction strategy.

The three-scope framework covers all major greenhouse gases - carbon dioxide, methane, nitrous oxide, and fluorinated gases - expressed as CO2e. A company's carbon footprint is the sum of greenhouse gases across all three scopes - and for most fleet operators, cutting greenhouse gases starts with scope 1. Accurately reducing a company's greenhouse gas emissions requires knowing which scope each source sits in, because managing scope 1, scope 2, and scope 3 chain emissions calls for different strategies and tools.

2. Scope 1 Emissions: What Fleet Managers Own Directly

Scope 1 emissions are direct GHG emissions from sources owned or controlled by an organization. They cover all greenhouse gases released through fuel combustion in vehicles and equipment - including carbon dioxide, methane, and the fluorinated greenhouse gases found in refrigeration systems and cooling systems that escape as fugitive emissions - as well as process emissions from industrial processes on site. Scope 1 includes emissions generated by every combustion source your organization owns or operates. For commercial fleets, the dominant emissions source for most fleets is burning fuel in diesel and gasoline vehicles - emissions entirely within your operational control.

Every delivery truck, service van, and long-haul trailer running on combustion contributes to your company's emissions. Transitioning to electric vehicles eliminates tailpipe emissions from your fleet, making it one of the most direct and measurable actions available for reducing a company's carbon emissions.

Calculating Scope 1 Emissions from Diesel and Gas Fleets

The standard approach applies emissions factors from Environment and Climate Change Canada: approximately 2.68 kg of CO2e per litre of diesel, 2.31 kg per litre of gasoline. A fleet consuming 500,000 litres of diesel annually generates roughly 1,340 tonnes of CO2e - direct GHG emissions from owned or controlled sources entirely within your operational boundary. NRCan's Energy Efficiency Benchmarking tools provide additional frameworks for calculating and benchmarking energy use across industrial operations.

This calculation is your baseline. Once established, you can set reduction targets, track emissions through direct measurement by vehicle and route, and report a company's operations emissions with confidence - including emissions generated by each vehicle class across your fleet.

Why Scope 1 Is the First Target for Fleet Electrification

Scope 1 reductions from fleet electrification are straightforward to calculate and verify: when a diesel van is replaced by an electric van, those direct emissions drop to zero. Unlike scope 3 reductions - which involve complex supplier engagement - scope 1 results are immediate, auditable, and directly tied to replacing fossil fuels with electricity. That clarity matters to CFOs, clients, and auditors alike.

3. Scope 1 and 2 Emissions: The Operational Footprint of Your Fleet

Scope 1 and 2 emissions together define your fleet's full operational carbon footprint, covering both scope 1 and scope 2 from your core operations. While scope 1 covers what your vehicles burn directly, scope 2 covers the greenhouse gas emissions associated with purchased electricity used to power your operations - including the electricity used to charge EVs.

Scope 2 emissions originate outside your organization but are driven by your energy consumption. They appear on your energy bills as purchased electricity - greenhouse gases released at the power plant, not at your facility, but caused by your demand. This is the key distinction between direct and indirect emissions: direct emissions come from sources you own, indirect emissions come from activities you drive but do not control.

Fleet operators can reduce scope 2 emissions by purchasing electricity from cleaner sources, reducing depot consumption, or procuring renewable energy certificates. British Columbia and Quebec have emissions factors close to zero for hydroelectric-dominated supply. In Alberta and Saskatchewan, where natural gas contributes more to the grid mix, scope 2 from EV charging is higher - though still significantly lower than scope 1 from the diesel vehicles being replaced.

Pairing EV charging with renewable energy - wind turbines, solar, or green tariffs - cuts the greenhouse gases attributable to your purchased energy further. Fleet managers who track greenhouse gases across both scope 1 and scope 2 simultaneously achieve the most defensible carbon accounting outcomes. Together, scope 1 and scope 2 typically represent 10 to 30% of a company's total carbon footprint - with the remaining 70 to 90% sitting in scope 3 emissions. Canada's greenhouse gas reporting frameworks set the regulatory context within which scope 2 reporting obligations are evolving.

4. Scope 3 Emissions: Supply Chain, Logistics, and Where EVs Make the Biggest Difference

Scope 3 emissions are all other indirect greenhouse gas emissions across a company's value chain - upstream from suppliers and downstream from customers. Unlike the indirect emissions in scope 2 (limited to purchased energy), scope 3 covers production processes, employee commuting, leased assets, waste disposal, and other scope 3 categories throughout the value chain. For most organizations, scope 3 represents 70 to 90% of a company's greenhouse gas emissions - making scope 3 the single largest category in a company's carbon footprint.

For most organizations, scope 3 accounts for 70 to 90% of total emissions across the entire value chain - covering raw materials, production processes, employee commuting, leased assets, waste generated, and life cycle emissions throughout the supply chain. For fleet-intensive businesses, upstream and downstream transportation are typically the most material categories.

Value chain emissions are split between upstream and downstream: upstream emissions occur before goods reach your operation (raw materials, freight), downstream emissions occur after (outbound distribution, customer transportation). Upstream and downstream emissions from transportation are typically the most material scope 3 categories for fleet operators. For companies that contract third-party carriers, those carriers' combustion emissions land in scope 3 as other indirect GHG outputs and flow directly into a company's greenhouse gas emissions total. Understanding your company's supply chain exposure across each scope 3 category is essential for prioritizing reductions.

If you operate an EV fleet on behalf of clients - or if you are a shipper choosing between carriers - the emissions profile of the vehicles doing the work flows directly into scope 3 accounting. Shippers working with EV-fleet partners can report lower scope 3 emissions, a differentiator increasingly showing up in logistics tender requirements.

Common high-impact scope 3 emissions categories for fleet-heavy operators include upstream transportation, downstream distribution, and employee commuting. Reducing scope 3 through fleet electrification is one of the most scalable interventions available - it can be implemented within a single procurement cycle rather than requiring years of supplier engagement. For organizations looking to reduce indirect greenhouse gas emissions tied to logistics, partnering with an EV fleet provider is the most direct step available. An EV fleet partner also provides the emissions data infrastructure needed to measure and report scope 3 emissions reductions - turning indirect emissions that were previously estimated into verified, auditable figures.

6. How 7Gen's EV-as-a-Service Model Supports Measurable Carbon Emissions Reduction

7Gen's EV-as-a-Service model removes the barriers that prevent fleet operators from acting on what the emissions math already supports. By bundling EV leasing, charging infrastructure, maintenance, energy management, and fleet software into a single monthly payment, 7Gen eliminates the capital planning complexity that most often stalls electrification decisions.

From a greenhouse gas accounting perspective, every vehicle deployed through 7Gen's platform converts a source of direct scope 1 emissions - burning fuel through combustion - into a zero-tailpipe-emission asset. The result is a direct, verifiable reduction in carbon emissions, with scope 1 and scope 3 emissions data built into the reporting from day one. Fleet managers gain the data infrastructure to track and report those reductions without building that capability internally: scope 1 baselines, charge consumption records, and route-level performance data that feeds directly into carbon accounting cycles and supports ongoing GHG tracking.
