You might not have read the Paris Agreement cover to cover, but there's a good chance you've heard about one of its primary goals: keeping the rise in global temperatures below 1.5°C. This figure hasn't been plucked from thin air - it's a crucial benchmark to keep the more extreme effects of climate change at bay.
So, what's the best way to achieve this? Well, the key is reducing greenhouse gas emissions (GHGs). And a big part of that comes down to keeping an eye on something called Scope 1, 2, and 3 emissions.
These categories aren't just industry jargon, they're key to identifying the sources of emissions and figuring out effective ways to reduce them and prevent global warming. In this article, we'll unravel these terms and explain why they're essential in our collective effort to combat climate change.
👉 In this article, we clarify what Scope 1, 2, and 3 emissions are and their significance in managing a company's carbon footprint.
Why is it important to work out Scope 1, 2, and 3 emissions? Let's start with a quick refresher: the greenhouse effect is a natural process that helps keep the Earth's temperature at a level suitable for human life. But here's the catch – the excessive GHG resulting from human activities is supercharging this effect, leading to a rise in the average global temperature. And the fallout? It's putting the Earth's ecosystems in a tight spot, threatening the delicate balance that supports life as we know it.
To effectively reduce your carbon emissions, whether as an individual or a company, the first step is understanding how much carbon you're actually emitting. This is where the concept of GHG emissions Scopes comes into play. They provide a structured way to categorise and measure these emissions, laying the foundation for targeted strategies to cut down on carbon output.

To understand Scope 1, 2, and 3 emissions we need to look to the Greenhouse Gas Protocol. This initiative is a comprehensive multi-stakeholder partnership, encompassing businesses, non-governmental organisations (NGOs), governmental bodies, and other entities, all brought together by the World Resources Institute (WRI) in 1998.
Their mission? To develop and establish international standards for accounting and reporting GHG emissions for businesses and to encourage widespread adoption.
Over the years, the GHG Protocol has expanded to include several standards, each designed to address different aspects of greenhouse gas measurement and management. Below is a brief overview of the key standards:
Standard | Purpose | Best For |
---|---|---|
Corporate Accounting and Reporting Standard | Provides requirements and guidance for companies and other organizations to prepare a corporate-level GHG emissions inventory. | Companies and Organizations |
Corporate Value Chain (Scope 3) Standard | Allows companies to assess their entire value chain emissions impact and identify where to focus reduction activities. | Companies and Organizations |
Product Life Cycle Accounting and Reporting Standard | Helps understand the full life cycle emissions of a product and focus efforts on the greatest GHG reduction opportunities. | Companies and Organizations |
Policy and Action Standard | Offers a standardized approach for estimating the greenhouse gas effect of policies and actions. | Countries and Cities |
Mitigation Goal Standard | Provides guidance for designing national and subnational mitigation goals and a standardized approach for assessing and reporting progress toward goal achievement. | Countries and Cities |
GHG Protocol for Cities (Global Protocol for Community-Scale GHG Emission Inventories) | Provides a robust framework for accounting and reporting city-wide greenhouse gas emissions. | Cities and Communities |
GHG Protocol for Project Accounting | The most comprehensive, policy-neutral accounting tool for quantifying the greenhouse gas benefits of climate change mitigation projects. | Companies and Organizations; Countries and Cities |

The term 'Scope emissions' first made its appearance in the GHG Protocol Corporate Accounting and Reporting Standards (the gold standard for corporate carbon accounting). These standards are a go-to resource for companies aiming to measure and report their GHG emissions accurately. They play a crucial role in breaking down a company's emissions into distinct categories, which are more commonly known as 'scopes.' More specifically, Scope 1, Scope 2, and Scope 3 emissions - each category represents a different source of emissions.
Let's break down these categories:
Scope | Description | Examples |
---|---|---|
Scope 1 | Direct emissions from sources owned or controlled by the company. |
- Fuel combustion from company-owned vehicles - Emissions from on-site boilers, furnaces, and generators - Process emissions from chemical production in owned facilities - Fugitive emissions from refrigeration or air conditioning leaks |
Scope 2 | Indirect emissions from the generation of purchased electricity, steam, heat, or cooling. |
- Electricity used in offices and manufacturing plants - Purchased heating or cooling for office buildings - Steam used in industrial production processes - District energy systems |
Scope 3 | All other indirect emissions in the value chain, not included in Scope 2. |
- Purchased goods and services (e.g., raw materials, office supplies) - Business travel (e.g., flights, hotel stays) - Employee commuting (e.g., car, bus, or train) - Waste disposal (e.g., landfill, incineration) - Use of sold products (e.g., fuel in cars sold by an auto manufacturer) - Transportation and distribution (e.g., third-party logistics) - End-of-life treatment of sold products (e.g., recycling, disposal) |
By understanding and categorising emissions in this way, companies can develop more targeted strategies to reduce their overall carbon footprint.
Let's explore the different scopes in more detail.
Scope 1 emissions are directly released into the atmosphere as a result of a company's activities. These direct emissions originate from resources that are owned or controlled by the company. To ensure comprehensive tracking and management, Scope 1 emissions are categorised into four distinct groups:
Unlike Scope 1 which covers direct emissions, Scope 2 emissions refer to indirect GHG emissions that arise from the consumption of purchased electricity, steam, heat, and cooling in buildings and production processes. These emissions are classified separately because they originate from sources not directly controlled by the company.
The majority of Scope 2 emissions typically stem from electricity consumed by the company. This category encompasses the indirect emissions produced during the generation of the electricity purchased, which is then transmitted and distributed to the company.
Scope 3 emissions represent a significant part of GHG accounting. However, because it involves quantifying carbon emissions associated with a company's supply chain it is often seen as the most challenging to quantify. Unlike Scope 1 and 2 emissions, Scope 3 emissions are not directly linked to the company's own operations, but rather to the entire value chain, incorporating both upstream and downstream emissions. These significant carbon emissions are associated with the company's operations, yet they occur outside of its direct control.
Scope 3 emissions encompass a wide range of indirect emissions, examples include:
Scope 3 emissions provide a comprehensive view of a company's environmental impact, extending beyond its immediate operations to the broader impacts associated with its value chain emissions.
💡 Scope 3 emissions typically constitute the majority of a company's greenhouse gas output. According to the World Economic Forum, value chain emissions can account for as much as 70% of a business's total emissions footprint.
Unless a company has significant real estate holdings and energy consumption the majority of a company's total greenhouse gas emissions, around 70%, typically comes from Scope 3 sources. This statistic underscores the extent to which a company's environmental impact extends beyond its direct activities, into its wider value chain. Addressing these emissions is crucial not only for reducing a company's carbon footprint but also for identifying cost efficiencies and reinforcing sustainable practices.
Additionally, it's revealing to note that 71% of global emissions can be traced back to just 100 companies. This fact emphasises the enormous responsibility and influence businesses have in tackling global warming. Nowadays, the role of businesses extends beyond mere product and service delivery; they are expected to be at the forefront of environmental responsibility. The growing demand from customers, employees, and investors is for companies to actively incorporate sustainability and environmental considerations into their operations.
Companies that embrace sustainable practices also position themselves for new growth and investment opportunities. Those who ignore this shift risk falling behind, as regulatory environments tighten and consumer expectations lean heavily towards environmental stewardship.
Measuring all emissions, particularly Scope 3, is therefore not just a regulatory formality, it's a strategic necessity, allowing companies to:
When we talk about measuring carbon footprints in terms of carbon and carbon dioxide equivalents, we are referring to the quantification of different greenhouse gases (GHGs) in terms of their impact on global warming. This measurement is crucial because different gases have varying levels of effect on the Earth's atmosphere.
The most common unit of measurement is the carbon dioxide equivalent (CO2e), which standardises various GHGs based on their Global Warming Potential (GWP).
Carbon dioxide (CO2) is the most prevalent GHG emitted through human activities, such as fossil fuel combustion and deforestation. It serves as the baseline for the CO2e metric, with a GWP of 1.
Other greenhouse gases like methane(CH4), nitrous oxide (N2O), and fluorinated gases (HFCs, PFCs, SF6, and NF3) are also significant contributors to global warming. Each of these gases differs in GWP and atmospheric lifespan:
Gas | Global Warming Potential (GWP) | Atmospheric Lifespan | Common Sources |
---|---|---|---|
Carbon Dioxide (CO2) | 1 | 300–1,000 years | Burning fossil fuels, deforestation, cement production |
Methane (CH4) | ~28–34 (over 100 years) | ~12 years | Agriculture (livestock digestion), landfills, natural gas extraction |
Nitrous Oxide (N2O) | ~265–298 | ~114 years | Fertilizers, industrial processes, combustion of fossil fuels |
Hydrofluorocarbons (HFCs) | 12–14,800 | 15–29 years | Refrigeration, air conditioning, aerosol propellants |
Perfluorocarbons (PFCs) | ~6,500–12,200 | Thousands of years | Aluminum production, semiconductor manufacturing |
Sulfur Hexafluoride (SF6) | ~23,500 | ~3,200 years | Electrical insulation, circuit breakers |
Nitrogen Trifluoride (NF3) | ~17,200 | ~500 years | Semiconductor manufacturing, LCD panel production |
Understanding and reporting Scope 1, 2, and 3 emissions is not just about categorising emissions - it’s about ensuring transparency, regulatory compliance, and aligning with climate action goals to reduce emissions. Each scope plays a unique role in reporting, helping organisations measure their impact comprehensively and communicate effectively with stakeholders.
Purpose: These emissions give organisations a clear picture of their direct environmental footprint, offering a starting point for reductions.
Purpose: Scope 2 highlights an organisation’s reliance on energy and identifies opportunities to transition to renewable sources.
Purpose: Scope 3 reporting provides a complete view of an organisation’s environmental impact, enabling them to address emissions across their value chain.
Incorporating all three scopes into emissions reporting achieves several goals:
Scope | Reported Where? | Purpose in Reporting | Challenges |
---|---|---|---|
Scope 1 | Regulatory frameworks (e.g., EU ETS), internal reporting | Tracks direct impact and sets a baseline for reductions. | Accurate measurement of fugitive and process emissions. |
Scope 2 | Corporate sustainability reports, CDP, TCFD | Highlights energy consumption and opportunities for renewables. | Adjusting for renewable energy credits or grid factors. |
Scope 3 | ESG disclosures, SBTi, voluntary initiatives | Provides a complete picture of environmental impact. | Data collection across supply chains and value chains. |
While Scope 1, 2, and 3 emissions provide a clear framework for categorising and understanding greenhouse gas emissions, putting this knowledge into practice can be challenging. For many companies, measuring and reporting emissions requires navigating a complex web of data collection, reporting frameworks, and value chain engagement.
