What is Carbon Accounting? A Clear Definition with Examples

Carbon accounting, or greenhouse gas accounting, is a method for companies and organizations to quantify their greenhouse gas (GHG) emissions. This system functions similarly to financial accounting, providing a framework for measuring and tracking the amount of GHGs released into the atmosphere.

As climate change becomes an increasingly prominent concern, understanding a company’s carbon footprint has emerged as a crucial aspect for businesses aiming to reduce their environmental impact and adhere to compliance regulations.

In order to accurately assess an organization’s carbon emissions, carbon accounting is categorized into three distinct scopes. These scopes represent different levels of emission sources and range from direct emissions produced by an organization to indirect emissions generated throughout its supply chain.

By utilizing these classifications and analyzing real-time and historical energy data, companies can trace emissions to their origin, enabling informed decision-making to reduce their overall carbon footprint and enhance their sustainability efforts.

Implementing carbon accounting practices can lead businesses towards a more environmentally conscious approach, proving beneficial in reducing negative impacts on the planet, enhancing the company’s reputation, and aligning with increasing demands for sustainable and responsible operations.

As more corporations become aware of the significance of their carbon emissions, embracing carbon accounting is essential in moving towards a sustainable and eco-friendly future.

What is Carbon Accounting?

Carbon accounting, also known as greenhouse gas (GHG) accounting, is a technique businesses and organizations use to measure and track the amount of greenhouse gases they produce. The primary purpose of carbon accounting is to provide a clear understanding of an entity’s GHG emissions and the potential impact their operations have on the environment.

Greenhouse gas emissions predominantly consist of carbon dioxide (CO2), the most common GHG emitted by human activities. However, other GHGs such as methane (CH4) and nitrous oxide (N2O) are also accounted for when quantifying an organization’s emissions. These gases contribute to climate change, and accurately accounting for them is essential in managing environmental risks and sustainability performance.

In carbon accounting, emissions are classified into three distinct categories, known as “scopes”. Scope 1 emissions are directly produced from the organization’s activities, such as burning fossil fuels for energy or transportation. Scope 2 emissions result from generating electricity, heat, or steam purchased and consumed by the organization. Finally, Scope 3 emissions encompass indirect emissions from an organization’s value chain, including sourcing materials, transportation, and waste disposal.

Accurate carbon accounting is becoming increasingly vital for businesses and organizations as governments introduce new regulations and investors shift capital toward more sustainable companies. Moreover, it enables entities to identify potential reduction strategies and track the progress of emissions-reducing projects, such as implementing renewable energy sources or increasing energy efficiency.

Emission Scopes in Carbon Accounting

Carbon accounting measures, analyzes and reports an organization’s greenhouse gas (GHG) emissions. To thoroughly account for these emissions, they are categorized into three distinct scopes, which are Scope 1, Scope 2, and Scope 3 emissions.

Scope 1 emissions are also referred to as direct emissions. These emissions originate from sources owned or controlled by an organization, such as emissions produced during manufacturing processes, fugitive emissions like methane leaks from coal mining, or onsite electricity generation by burning fossil fuels.

Direct emissions significantly impact an organization’s carbon footprint and are thus integral to any carbon accounting exercise.

Scope 2 emissions are indirect emissions that result from the consumption of purchased electricity, heat, or steam by an organization. These emissions are connected to the organization’s activities but occur at the facilities where electricity is generated.

For accurate carbon accounting, it’s essential to account for Scope 2 emissions since they reflect the organization’s overall energy consumption and dependency on external suppliers.

Scope 3 emissions encompass all other indirect emissions not included in Scope 2. These emissions are linked to the organization’s activities but occur from sources not owned or controlled by the organization. Scope 3 emissions can include business travel, employee commuting, waste disposal, and production and distribution of products and services throughout the supply chain.

To accurately calculate and report the carbon emissions within these scopes, carbon accounting practices use emission sources, emissions factors, and emission factors. Emission sources refer to the various activities and processes that generate GHG emissions. In contrast, emission factors are coefficients that convert activity data into GHG emissions, usually expressed as kilograms or metric tons of CO2 equivalent per unit of activity.

In summary, Emission Scopes in Carbon Accounting are crucial in understanding and managing an organization’s carbon footprint. By considering Scope 1, Scope 2, and Scope 3 emissions, carbon accounting practices provide a holistic approach to GHG management and enable organizations to address their environmental impact responsibly.

Carbon accounting methodologies provide systematic approaches to quantify and manage greenhouse gas (GHG) emissions generated by an organization or specific project. These methodologies encompass data collection, analysis, and reporting processes to track and manage emissions effectively and offer a pathway for organizations to identify areas for improvement in their carbon management strategies.

One widely accepted and recognized framework for carbon accounting is the GHG Protocol. Developed jointly by the World Business Council for Sustainable Development (WBCSD) and the World Resources Institute (WRI), the GHG Protocol offers national and corporate carbon accounting software and standards, helping organizations measure, manage, and report GHG emissions.

The GHG Protocol consists of three scopes of emissions (Scope 1: direct, Scope 2: indirect energy, and Scope 3: indirect non-energy) that allow a comprehensive evaluation of an organization’s carbon footprint.

Another critical component of carbon accounting methodologies is the process of greenhouse gas accounting. This involves collecting, collating, and analyzing emissions data and preparing estimates per the chosen accounting framework-based method.

Accurate measurements of GHG emissions are vital in developing an effective carbon management strategy, as they indicate potential emission reduction and performance improvement areas.

In order to create a GHG inventory, organizations must adhere to specific standards and guidelines, such as the GHG Protocol Standard. This process facilitates the identification and categorization of emission sources, the collection and analysis of emissions data, and the reporting of the final inventory results. By following a robust and reliable methodology, organizations can ensure that their GHG inventory is accurate and consistent.

As mentioned earlier, the GHG Protocol provides a comprehensive framework for conducting carbon accounting, but other carbon accounting methodologies are available. Choosing the right methodology depends on the organization’s goals, industry, and regulatory requirements.

Despite the differences in methodologies, they all place paramount importance on the accuracy and precision of measurements, emissions data, and emissions estimates.

Carbon Accounting and Supply Chains

Carbon accounting, or greenhouse gas (GHG) accounting, is how organizations quantify their GHG emissions to understand their climate impact and set goals to limit emissions. This technique is essential for businesses to measure their direct and indirect carbon emissions, which can be categorized into Scope 1, 2, and 3.

Carbon accounting is crucial in ensuring sustainability and addressing climate change in supply chains. The emissions related to supply chain activities, such as production, distribution, transportation, and product use, predominantly fall within Scope 3. These emissions use value chains, which embody carbon accounting, which is important at each step of the product life cycle, from raw material extraction to product disposal.

Organizations must account for their supply and financial value chain emissions to minimize their carbon footprint. By doing so, they can identify areas within the value chains that contribute the most to their emissions. Key components in the value chain that contribute to GHG emissions include:

• Distribution: The emissions associated with transporting goods from production facilities to distribution centers and retail outlets.
• Transportation: Emissions deriving from the movement of goods, including raw materials, work-in-progress, and finished products.
• Sold products: The end-user emissions stemming from the use and disposal of products a company sells.

Companies must adopt comprehensive carbon accounting practices to reduce carbon emissions across their supply chain to enhance their sustainability efforts. Several tools and methodologies are available to quantify these emissions, such as:

• Life Cycle Assessment (LCA): Evaluating the environmental impacts associated with each product’s life cycle stage.
• Greenhouse Gas Protocol: A widely used international accounting tool for businesses to measure and manage GHG emissions.

By understanding the emissions within their value chains, businesses can make informed decisions, set reduction targets, and implement strategies, such as switching to renewable energy sources or engaging in energy-efficient practices. As a result, organizations can manage their supply chain emissions effectively, contributing to a more sustainable and low-carbon economy.

Carbon Offsetting and Markets

Carbon offsetting is a carbon accounting that refers to a mechanism companies and individuals use to compensate for their greenhouse gas (GHG) emissions by investing in projects that reduce or remove them elsewhere.

This is often done by purchasing carbon credits or offsets through a platform such as Arcadia. A carbon credit represents reducing or removing one metric ton of carbon dioxide equivalent (CO2e) from the atmosphere.

Carbon markets facilitate trading carbon offsets and credits, allowing companies to meet their carbon reduction targets and support projects that lower emissions. The market is divided into two major types: the compliance market and the voluntary market.

Compliance markets are regulated under international agreements such as the Kyoto Protocol and the Paris Agreement. In contrast, voluntary markets involve companies and individuals purchasing offsets of their own accord to meet specific reduction targets or show environmental responsibility.

One noteworthy example of carbon markets is the European Union Emissions Trading System (EU ETS), which operates in the compliance market. In the voluntary market, the Verified Carbon Standard and The Gold Standard are prominent entities certifying the quality and validity of carbon offsets.

Carbon accounting, also known as greenhouse gas accounting, is a way for companies to quantify the amount of GHGs they produce. This process is vital as it helps organizations calculate their carbon budgets and choose appropriate strategies to mitigate and offset their emissions. Accurate carbon accounting is crucial for transparent reporting, stakeholder communication, and regulatory compliance.

The carbon offset market is projected to grow significantly in the coming years, with estimates suggesting an increase from $2 billion in 2020 to around $250 billion by 2050.

Carbon Accounting and Organizational Boundaries

Carbon accounting, also known as greenhouse gas (GHG) accounting, is a method used by organizations to quantify and manage their greenhouse gas emissions.

The process involves measuring, analyzing, calculating, and reporting an organization’s emissions comprehensively and audibly. Understanding and managing an organization’s carbon footprint requires addressing three emissions levels, Scopes 1, 2, and 3, and defining organizational boundaries.

Organizational boundaries delineate what sources of greenhouse gas emissions are included in an organization’s carbon accounting. These boundaries define which indirect greenhouse gas emissions fall within an organization’s control or sphere of influence.

There are two types of boundaries: operational and equity-based. Operational boundaries focus on emissions from sources owned or controlled by the organization, whereas equity-based boundaries consider emissions from sources where the organization has an ownership stake.

• Scope 1 emissions are direct emissions from sources owned or controlled by the organization, such as manufacturing processes, fugitive emissions (like methane emissions from coal mining), or onsite electricity production by burning fossil fuels.
• Scope 2 emissions indirect emissions from purchased electricity, heat, or cooling consumption. An organization’s energy generation produces these emissions from a third-party provider. Reducing Scope 2 emissions can be achieved through energy efficiency measures or procuring renewable energy.
• Scope 3 emissions are indirect emissions not covered by Scope 2 and originate from sources outside an organization’s direct control. Examples include employee commuting, business travel, outsourced activities, and the production of purchased goods and services. Scope 3 emissions often represent a significant portion of an organization’s total emissions and provide opportunities for emissions reduction through supply chain optimization and engagement with suppliers.

In carbon accounting, properly defining organizational boundaries and understanding the various types of emissions allows organizations to create effective management strategies and implement actions to reduce their carbon footprint. Accurate and transparent reporting of GHG emissions can also enhance an organization’s reputation and demonstrate a commitment to sustainable practices.

Carbon Accounting and Science-Based Targets

Carbon accounting, also known as greenhouse gas (GHG) accounting, is a method for organizations to quantify their emissions. This helps them understand their climate impact, set emission reduction goals, and track their progress in limiting emissions.

The process includes inventories of Scope 1 (direct), Scope 2 (indirect from purchased electricity, steam, heating, and cooling), and Scope 3 (other indirect emissions) emissions.

One significant application of carbon accounting to global warming is the adoption of science-based targets (SBTs). SBTs are emission reduction goals aligned with scientific recommendations and international climate commitments, such as the Paris Agreement. The Paris Agreement aims to limit the global temperature increase to below 2°C above preindustrial levels while pursuing efforts to limit the increase to 1.5°C.

To set SBTs, organizations can join the Science Based Targets initiative (SBTi). The SBTi is a collaborative effort by CDP, the UN Global Compact, the World Resources Institute, and the World Wildlife Fund for Nature. It endorses companies’ emission reduction targets and ensures they align with climate science. By setting SBTs, businesses can contribute to global efforts to achieve a net-zero emission future, which is crucial for combating climate change.

Adopting SBTs and conducting carbon accounting allows companies to:

• Identify areas with high GHG emissions
• Develop data-driven strategies to reduce emissions
• Monitor progress and verify results
• Integrate climate action into their business model
• Demonstrate their commitment to sustainable development
• Improve brand reputation and attract sustainable investment
