Grasping the Concept of Carbon Footprint Scope 1 2 3
The Relevance of Carbon Footprint in Climate Change
Carbon footprint refers to the amount of greenhouse gas emissions caused directly or indirectly by an individual, organization, event or product. It is increasingly used as an indicator of an entity's contribution to climate change. As climate change continues to advance, there is growing pressure for businesses to measure, report on, and reduce their carbon footprints.
With more extreme and unpredictable weather patterns already evident globally, the need for climate action is urgent. Tracking carbon footprint enables quantification of emissions over time, serving as a benchmark for setting and achieving emissions reduction targets. For the world to reach net-zero emissions by 2050, as targeted by the Paris Agreement, businesses reducing their footprint is pivotal.
Businesses and the Climate Imperative
Businesses have an imperative role and opportunity in driving large-scale emission cuts. As major sources of global emissions, companies that achieve low-carbon operations and supply chains will be best positioned for long-term resilience. Those proactive on sustainability can also tap into growing customer demand for eco-conscious brands.
However, to contribute meaningfully, businesses need accurate carbon accounting. Monitoring emissions across operations allows for informed decisions in diminishing environmental impacts. Strategic tracking further provides substantiated proof of progress to stakeholders seeking evidence of climate responsibility.
Overview of Carbon Footprint Scope 1 2 3 Explained
The Greenhouse Gas (GHG) Protocol delineates carbon footprint into three categories based on emission source:
- Scope 1 – Direct emissions from owned/controlled operations
- Scope 2 – Indirect emissions from purchased energy
- Scope 3 – All other indirect emissions from the value chain
While Scope 1 and 2 emissions derive from a company’s direct activities, Scope 3 emissions often form the majority of an organization’s carbon footprint. These encompass indirect emissions occurring across the broader supply chain, from raw material extraction to product disposal.
For small and medium enterprises (SMEs), calculating Scope 3 emissions poses particular challenges due to complex value chains. However, given their magnitude, consistently tracking and reducing Scope 3 emissions is essential for driving deep decarbonization. Understanding the differences between carbon footprint Scope 1 2 3 enables SMEs to pinpoint and address their biggest climate impacts.
What are scope 1 2 and 3 carbon emissions?
Scope 1, 2, and 3 emissions refer to different categories of greenhouse gas (GHG) emissions that make up a company or organization's carbon footprint. Understanding these categories is an important first step for businesses looking to measure, report on, and reduce their emissions.
Scope 1 Emissions
Scope 1 emissions are direct GHG emissions that come from sources owned or controlled by the company. This includes emissions from:
- Combustion of fuels in company vehicles, equipment, and facilities
- Manufacturing processes and chemical reactions
- Fugitive emissions like refrigerant leaks from AC units
Measuring scope 1 emissions gives companies clarity on emissions sources they can directly manage and reduce.
Scope 2 Emissions
Scope 2 accounts for indirect GHG emissions from the electricity a company purchases. Even though the actual emissions occur at the power plant, they are considered indirect emissions for the company using the electricity.
As energy grids shift to renewable sources, companies can reduce scope 2 emissions by purchasing green power.
Scope 3 Emissions
Scope 3 emissions are all other indirect emissions occurring in a company's value chain. This wide-ranging category includes emissions from:
- Employee travel
- Transportation of purchased goods
- Waste disposal
- Use of sold products
Understanding scope 3 emissions shows a company where it has influence to drive emission reductions through procurement policies, product design, and more.
Measuring and reporting on all three scopes gives companies a complete view of their carbon footprint to set informed reduction targets. Integrating carbon footprint scope 1 2 3 tracking into business processes is key for organizations on the path to net zero emissions.
What does Scope 1 emissions include in a carbon footprint?
Scope 1 emissions refer to the direct greenhouse gas (GHG) emissions that come from sources owned or controlled by a company. Some examples of Scope 1 emission sources include:
- Fuel combustion in boilers, furnaces, vehicles, and equipment owned by the company
- Fugitive emissions from refrigeration, air conditioning units, and other equipment
- On-site landfills, wastewater treatment plants, and other waste processing facilities
Accounting for Scope 1 emissions provides companies a fuller picture of their carbon footprint. It allows them to identify major sources of emissions they can directly control and reduce.
For many small and medium enterprises (SMEs), Scope 1 emissions may include:
- Gas, oil, or propane burned for heating facilities
- Gasoline/diesel used in company fleet vehicles
- Emissions from company machinery and equipment
Properly tracking Scope 1 emissions can help SMEs:
- Comply with emissions regulations and required reporting
- Set goals to reduce carbon footprint
- Identify cost savings from energy efficiency
What are the three scopes of carbon footprint analysis?
Understanding the three scopes of carbon emissions is key for SMEs looking to accurately measure and reduce their carbon footprint. The Greenhouse Gas (GHG) Protocol defines scope 1, 2, and 3 emissions as follows:
Scope 1 emissions come directly from sources owned or controlled by the company. This includes fuel combustion, company vehicles, and industrial processes. For example, an SME's scope 1 emissions would include gas used for heating their office space.
Scope 2 accounts for indirect GHG emissions from purchased electricity used by the company. Even though the actual emissions occur at the power plant, they are considered scope 2 for the SME using that electricity.
Scope 3 emissions encompass all other indirect emissions across a company's value chain. This includes activities not owned or controlled by the company but related to their operations. For instance, employee commuting, business travel, transportation logistics, and emissions from product use and disposal are all examples of scope 3.
Understanding these distinctions is crucial when measuring and reporting carbon footprint. Getting a handle on scope 1 and 2 emissions can give SMEs better control and options to switch to renewable energy. Addressing scope 3 emissions involves working with partners to reduce activities outside the company's direct control. Accurately tracking all three scopes provides the full picture of a carbon footprint.
What is the difference between GHG Scope 2 and Scope 3?
Scope 2 emissions refer to indirect greenhouse gas (GHG) emissions from the generation of purchased or acquired electricity, steam, heating, or cooling. These emissions physically occur at the facility where energy is generated rather than where it is eventually consumed.
Scope 3 emissions encompass all other indirect emissions across a company's entire value chain. This includes activities not owned or controlled by the reporting company but are related to its upstream and downstream operations.
Here are some key differences between Scope 2 and Scope 3:
-
Source of Emissions: Scope 2 covers emissions from a company's energy suppliers. Scope 3 includes emissions from broader supply chain activities and product use.
-
Level of Influence: Companies have more direct influence and control over Scope 2 emissions through their energy procurement decisions. Scope 3 emissions often depend on external suppliers or customers over which a company can only exert limited influence.
-
Ease of Accounting: Scope 2 emissions can be estimated more easily based on actual energy usage data. However, accurately tracking Scope 3 emissions involves collecting extensive supplier or value chain data which proves more difficult.
-
Reporting Requirements: Reporting Scope 2 emissions is mandatory under most carbon accounting frameworks, while detailed Scope 3 emissions reporting remains voluntary.
In summary, Scope 2 emissions stem directly from a company's energy use while Scope 3 emissions encompass all other activities across the wider product life cycle and supply chain. Understanding this difference provides companies a more complete view of their carbon impact.

Breaking Down Scope 1: Direct Emissions from Owned or Controlled Sources
Scope 1 emissions refer to direct greenhouse gas (GHG) emissions that occur from sources owned or controlled by a company. For small and medium-sized enterprises (SMEs), understanding Scope 1 is an important first step towards measuring and reducing their carbon footprint.
Understanding Scope 1 Emissions
Scope 1 includes emissions released directly into the atmosphere from sources within a company's operations. This can include:
- Combustion of fuels in company-owned equipment like boilers, furnaces, vehicles, generators, etc.
- Fugitive emissions that unintentionally leak during extraction, storage or transportation of fossil fuels.
- Process emissions from physical or chemical processing of materials.
Controlling these sources and tracking their emissions allows companies to take direct action to reduce their environmental impact.
Real-World Scope 1 Emissions Examples
Some examples of Scope 1 emission sources common for SMEs:
- A delivery fleet of diesel-powered company vehicles
- On-site natural gas consumption for heating/cooling buildings
- Refrigerant gases leaking from air conditioning units
- Transportation and distribution losses from stored fuel, if applicable
Monitoring fuel/energy use and emissions factors from owned equipment offers insights into an SME's carbon hotspots.
Managing and Reducing Scope 1 Emissions
Strategies SMEs can use to curb Scope 1 emissions include:
- Switching to renewable energy sources instead of fossil fuels
- Improving energy efficiency of buildings and transport
- Conducting regular maintenance to minimize leaks
- Investing in electric vehicles or optimizing logistics networks
Tracking and reporting Scope 1 emissions is the first step for SMEs to benchmark and lower their carbon footprint. Software tools like EcoHedge help automate emissions accounting across Scopes 1, 2 and 3.
Elucidating Scope 2: Indirect Emissions from Energy Purchases
Scope 2 emissions refer to indirect greenhouse gas (GHG) emissions associated with the purchase of energy. For small and medium-sized enterprises (SMEs), these emissions typically come from purchased electricity, steam, heating, and cooling.
Understanding Scope 2 is key for SMEs looking to reduce their carbon footprint. By tackling energy-related emissions, companies can make significant progress on their net zero commitments.
Defining Scope 2 GHG Emissions
The Greenhouse Gas (GHG) Protocol defines Scope 2 emissions as indirect emissions resulting from the generation of purchased or acquired electricity, steam, heating, or cooling. Although your business does not directly emit these GHGs, they occur in the production process as a result of your energy use.
Some examples of Scope 2 emission activities include:
- Purchased electricity used in offices and factories
- Purchased steam or district heating used in operations
- Loss of energy in delivery and transmission of electricity and steam
Measuring Scope 2 emissions allows SMEs to understand the impact of their purchased energy usage. It also helps identify opportunities to switch to renewable energy sources.
Scope 2 Emissions: Examples in Context
Here are some examples of how Scope 2 emissions might show up in an SME's carbon footprint:
-
A manufacturer that purchases electricity to power machinery and equipment would count the emissions associated with generating that electricity as Scope 2.
-
An office-based company that pays an energy provider to heat/cool their building would need to calculate emissions from their heating fuel usage as Scope 2.
-
A retailer that uses electricity to light and heat their stores must factor those indirect emissions under Scope 2 when reporting total carbon output.
In all these cases, Scope 2 captures emissions released during the production phase, even though the SME itself does not directly emit the GHGs on-site.
Tactics for Minimizing Scope 2 Carbon Impact
When it comes to energy procurement, SMEs have options to shrink their Scope 2 footprint. Some ideas include:
- Switching to renewable energy sources such as solar, wind, hydropower that have lower emissions profiles
- Improving energy efficiency through upgrades like LED lighting, smart thermostats, insulation
- Installing on-site renewables like solar panels or wind turbines to self-generate clean energy
- Purchasing renewable energy certificates (RECs) to offset use of fossil fuel-based grid electricity
Taking even small steps to tackle Scope 2 can significantly reduce an SME's overall carbon footprint. Most importantly, minimizing energy-related emissions paves the way toward net zero - and a more sustainable future.
Understanding Scope 3: The Broad Spectrum of Value Chain Emissions
Scope 3 emissions refer to indirect greenhouse gas emissions that occur across a company's value chain. This includes emissions from purchased goods and services, transportation and distribution, investments, employee commuting, waste disposal, and more. For many companies, Scope 3 emissions make up the majority of their carbon footprint.
Demystifying Scope 3 Emissions
Scope 3 emissions provide a more complete picture of a company's carbon impact. By assessing Scope 3, companies can identify emission hotspots to target for reduction. However, calculating Scope 3 emissions can be complex due to extensive data requirements across the value chain. Small and medium enterprises may lack resources to calculate complete Scope 3 inventories.
Despite challenges, addressing Scope 3 is becoming an imperative as stakeholders demand supply chain transparency and emissions regulations expand. By understanding Scope 3 sources, SMEs can begin addressing significant emissions, even with incomplete footprinting.
Illustrative Scope 3 Emissions Examples
Purchased Goods & Services: Emissions from extracting raw materials and manufacturing products an SME procures. For example, emissions from cotton farming and clothing production for a retail store.
Transportation & Distribution: Emissions from transportation, storage, and distribution of sold products between an SME's tier 1 suppliers through to end consumers. For example, emissions from parcel delivery for an e-commerce company.
Waste Disposal: Emissions from waste generated from operations, including product disposal by consumers at end-of-life. For example, emissions from customers discarding packaging from an SME's products.
Approaching Scope 3 Emission Reduction for SMEs
SMEs can take a phased approach to addressing Scope 3 emissions:
- Identify major Scope 3 categories based on sector guidance.
- Estimate & Report emissions from several key categories.
- Set Reduction Targets for priority categories and engage value chain partners.
- Refine Scope 3 inventory and strategy over time as capabilities allow.
Small actions can make an impact, such as choosing renewable energy providers or working with top-tier suppliers on sustainable sourcing initiatives.
Engaging the Supply Chain in Scope 3 Emission Management
SMEs can encourage emission reductions across their supply chain by:
- Communicating ambitions and priorities for sustainable procurement
- Incorporating sustainability criteria into supplier selection
- Providing training and resources to enhance suppliers' capacities
- Collaborating with industry peers to develop emissions standards
Progress will require persistence, but benefits include supply chain resilience, operational efficiency, and stakeholder trust.
Building a Carbon Footprint Inventory for SMEs
As small and medium-sized enterprises (SMEs) take steps to reduce their carbon footprint, the first critical task is to build an emissions inventory that captures the full scope of their greenhouse gas (GHG) impacts. This involves gathering data across the three scopes of emissions and using it to calculate a comprehensive carbon footprint baseline.
Gathering and Organizing Emissions Data
The starting point is compiling fossil fuel and electricity usage data to quantify Scope 1 and 2 emissions. This includes direct emissions from sources owned or controlled by the company, like fuel burned for heating or fleet vehicles, as well as indirect emissions from purchased electricity. Organizing this energy data by type, source locations, and usage periods facilitates the emissions calculations.
Expanding Inventory to Include Scope 3 Data
Scope 3 covers all other indirect emissions across an SME's value chain. While more challenging to measure, major categories like purchased goods/services, transportation, waste, and employee commuting should be included to provide a complete carbon inventory. Benchmarks and estimations can be utilized where supplier-specific data is unavailable.
Utilizing Technology and Tools for Carbon Accounting
Online tools and carbon accounting software integrate emissions factor databases to streamline the carbon footprint analysis process for SMEs based on the collated data. These platforms provide customized reporting and dashboards to identify hotspots, track performance over time, and inform reduction strategies.
Benchmarking and Continual Inventory Improvement
