TL;DR: CO₂ emission factors are key to understanding and managing your carbon footprint. By measuring emissions across all three scopes, you can make informed decisions to reduce emissions, save costs, and meet sustainability goals. Tools like the carbon footprint calculator from Regreener and expert consulting can help you to track, analyze, and reduce your carbon impact effectively.
Introduction to CO2 emission factors
Carbon dioxide (CO₂) is a big theme on the current climate agenda. But what is CO2? It is invisible and odorless. It is a byproduct of our combustion, consumption, and convenience. But if CO₂ is so hard to see, how can we track it? And how do we know how much is being released, and from where?
The answer to these questions begins with one term: CO₂ emission factors.
These factors are basically a bridge between our actions and the emissions. Almost all of our activities, from burning fuel, to using electricity, has an associated emission factor, a value that estimates how much CO₂ (or CO₂-equivalent) is released per unit of activity.
Consider this simple equation to visualize it better:
Activity Data × CO2 Emission Factor = CO2 Emissions
For example, when you drive 100 kilometres, multiplying this distance by the vehicle's emission factor (like 120g CO2/km) reveals your total CO2 emissions from that journey.
In today's climate-conscious world, it is important that we understand CO2 emission factors. If you own a business, understanding your emissions can help you for example to:
Make informed decisions about energy usage
Plan strategic for sustainability initiatives
Comply with environmental regulations
Reduce costs through efficient resource management
If you want to implement effective climate action to your company, the ability to measure and understand CO2 emissions the foundation is essential. By grasping these fundamental metrics, you can develop targeted strategies to reduce your carbon footprint and contribute to global climate goals.

Types and sources of CO2 emission factors
CO2 emission factors vary significantly based on their sources and the specific activities that generate them. These factors are categorized into three distinct scopes, each representing different aspects of an organization's carbon footprint.
Scope 1: direct emissions
At the core are Scope 1 emissions. If you own a company, then these emissions occur from sources directly that are directly owned or controlled by your company. These are the also the most tangible. Scope 1 emissions stem from two primary categories:
1. Stationary Combustion Sources, such as power plants, industrial boilers, manufacturing facilities, on-site generators or commercial heating systems.
2. Mobile Combustion Sources, such as company-owned vehicles, aircraft fleets, ships or construction equipment.
The emission factors for these sources depend heavily on the type of fuel that they use. Each fuel type produces different emission levels due to their unique chemical composition and energy content. Coal emits for example more CO2 than Gas, as can also be seen on the Dutch website for emission factors:
For each fuel type and their CO2 impact, there are however also other factors that can affect the emission rates.
Key Factors Affecting Emission Rates
Fuel quality and composition
Combustion technology efficiency
Operating conditions
Maintenance practices
Equipment age and design
Understanding these variations can help you to make informed decisions about what fuels to choose and what equipment to use or upgrade to reduce your carbon footprint. The accurate measurement of these emission factors enables precise tracking of greenhouse gas emissions and supports effective climate action strategies.
Scope 2: indirect emissions from electricity consumption
Moving one layer out, we encounter Scope 2—emissions from the generation of purchased electricity, steam, heat, or cooling. Though these emissions occur physically at the power plant, they are counted by the end-user, because their demand drives the production. The carbon intensity of electricity varies significantly based on the generation methods that are used in different regions and countries. So the location and time of the day is important, but also way how the energy is generated. Coal fired plants emit for example more (820-1,040 g CO2e/kWh) than solar power (6 g CO2e/kWh) or nuclear power (3 g CO2e/kWh).
You can reduce your Scope 2 emissions by choosing renewable energy providers or implementing on-site renewable energy solutions. The carbon intensity of electricity consumption directly impacts your environmental performance and sustainability goals.
The variation in emission factors between different electricity sources creates opportunities for strategic energy choices that align with carbon reduction objectives.
Scope 3: other indirect emissions throughout the product lifecycle
The third and most complex category is Scope 3, which encompasses all other indirect emissions that occur across a company’s value chain. These are not owned or directly controlled by your company but are nonetheless linked to its activities.
Scope 3 is often broken down into upstream and downstream emissions:
Upstream includes emissions from suppliers, business travel, employee commuting, and the production of purchased goods and services.
Downstream covers product distribution, use-phase emissions (e.g., energy consumed by a product), and end-of-life treatment.
Consider a tech company selling smartphones. The energy used to assemble the phones (Scope 1 and 2 of the supplier), the transportation of devices to retailers, and even the electricity consumed when users charge their phones at home all contribute to the tech company’s Scope 3 emissions. For many firms, Scope 3 can account for over 70% of total emissions.
You can address these challenges by implementing robust data collection systems, engaging with suppliers, and using standardized calculation methods from recognized frameworks like the GHG Protocol.

Measuring carbon footprint as part of a broader green strategy
Measuring your carbon footprint is an essential step if you want to make a commitment to protect the environment. A strong measurement system helps businesses to find the areas with high emissions, track the progress, and make informed decisions to improve sustainability.
The key components of carbon footprint measurement are:
Systematic data collection across all operational areas
Regular monitoring and reporting protocols
Standardized calculation methodologies
Clear benchmarking against industry standards
By integrating CO2 emission factor analysis into sustainability initiatives, you can:
Set science-based reduction targets
Develop effective mitigation strategies
Allocate resources efficiently
Track progress toward environmental goals
Business benefits of measuring your carbon footprint:
Measuring your carbon footprint goes beyond environmental responsibility, it provides strategic advantages that can strengthen both your operations and reputation.
First, there’s a clear reputational benefit. If you transparently track and reduce emissions, you can build stronger trust with stakeholders and improve your market positioning. In a competitive landscape where sustainability is increasingly valued, this can translate into enhanced brand loyalty and business opportunities.
It also supports regulatory readiness. As climate disclosure requirements become more stringent worldwide, early adoption of carbon accounting can help you to stay compliant, avoid regulatory risks, and to prepare for future policy changes.
Carbon measurement also often reveals opportunities for cost savings. Identifying inefficiencies, such as unnecessary energy use or wasteful processes, can reduce your operating costs and improve your resource management. In many cases, climate action drives innovation and operational improvements.
