What Is Carbon Accounting?

What Is Carbon Accounting?

This article is intended for organisations that wish to learn more about carbon accounting and what solutions are available to help reduce emissions.

We will cover what you need to know about financial carbon accounting, scopes of emissions, and a brief description of how to utilize Net0's carbon accounting platform to guide you along your net zero journey.

What are greenhouse gases?

Greenhouse gases are gases that trap heat in the atmosphere. They are produced through human activities, such as burning fossil fuels, clearing forests, and manufacturing cement. The most common GHGs are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases (such as hydrofluorocarbons, or HFCs).

When it comes to global GHG emissions, there are two important factors to consider: the amount of gas emitted and the gas's climate impact. The amount of gas emitted is measured in terms of metric tons (MT). The climate impact is measured in terms of carbon dioxide equivalent (CO2e)

One MT of CO2 is equivalent to 1,000 kilograms (kg) or 2,204 pounds (lbs). So, when we talk about emissions in terms of CO2e, we're talking about the amount of GHGs that is equivalent to 1,000 kg of CO2.

The most common GHGs are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases (such as hydrofluorocarbons, or HFCs). When we measure emissions in terms of CO2e, we're measuring the amount of all these gases combined.

What is the importance of carbon accounting?

Carbon accounting is essential for companies, governments, and other organisations. There are a few reasons why businesses should measure their carbon emissions.

First, by understanding how much carbon is released, businesses can develop strategies to reduce emissions or consider investing in offset projects. This can help them save money and fight against climate change.

Second, carbon accounting can also help organisations track the impact of their decisions on the environment. This information can help inform decision-making processes and allow companies to make more sustainable choices.

In addition, emissions reporting helps to create transparency and accountability around a company's carbon emissions. This is important because it helps investors and consumers make informed decisions about where to put their money.

Finally, measuring company's carbon footprint can also help businesses comply with government regulations.


How can businesses calculate greenhouse gas emissions?

Businesses can calculate their emissions by taking into account the sources of emissions within their organisation. These sources are typically divided into three separate categories or “scopes”:

Three scopes of carbon emissions

The Scope 1, 2 and 3 system has been developed by the Greenhouse Gas Protocol. Dividing emissions into three groups is intended to help measure progress in making the huge reductions in emissions needed to meet global targets.

Scope 1 emissions

Scope 1 emissions are direct emissions from owned or controlled sources, by the reporting company, during a production process with items that they own and control. Examples of scope 1 emissions include boilers, furnaces, emissions from machinery and equipment, fuel combustion, and vehicles which use fuel. They can also come from the production of energy used by a company, like for example, the burning of coal to produce electricity.

The amount of Scope 1 GHG emissions a company produces can vary depending on how much fuel they use and what kind of fuel it is. For example, a company that uses a lot of natural gas for heating and powering its operations will have lower Scope 1 emissions than one that relies heavily on coal.

Mandatory GHG reporting requires businesses to be transparent about their Scope 1 emissions in many regions across the world.

Scope 2 emissions

Scope 2 emissions are indirect emissions from purchased sources that the reporting company has made, that come from the generation of purchased electric, heating, cooling, gas, steam, and electric vehicles. Some common examples of industries with high scope 2 emissions include aluminium production and refining, cement production, and data centres.

Mandating the reporting of scope 2 emissions is becoming more common in many countries around the world.

Scope 3 emissions

Scope 3 emissions are all other indirect emissions that occur in a company’s value chain. There are 15 categories of corporate supply chain emissions that occur indirectly, (with regards to the reporting company), due to upstream and downstream activities throughout the value chain. Although these emissions occur on the outside of the reporting company's walls, they can be proactive in choosing resources, vendors, manufacturers, carriers, and distributors, and creating the life cycle of the product, to have a stronger, more sustainable value chain.

Please refer to our Scope 1, 2, and 3 Emissions article for a comprehensive understanding of direct and indirect emissions, upstream and downstream activities, and the 15 categories of scope 3.

As scope 3 regulations continue to evolve, the reporting requirements become more complex and new regulations encourage (and sometimes require) businesses to start measuring and reporting scope 3.

What are some challenges with greenhouse gas accounting?

Data accuracy

One challenge with carbon accounting is that it requires accurate data on a company's carbon emissions.

This data can be difficult to come by, as it requires monitoring of all activities that result in emissions (such as fuel consumption, electricity use, waste disposal, etc.). When it comes to collecting scope 3 emissions, companies require to collaborate with their suppliers across the supply chain to have an accurate understanding of the emissions. That can be a challenge on its own as it requires cooperation from multiple entities.

Net0’s platform solves this challenge with its integrated data collection and analysis capabilities. Net0 provides a carbon accounting platform for collecting data from all sources and performing detailed analysis to create an accurate picture of the company’s emissions across scope 1, 2 and 3. To collect accurate data for Scope 3 emissions specifically, Net0 offers a vendor outreach programme that allows businesses to effectively communicate with vendors, add them directly to the platform and automate data capture from them.

Ineffective data collection

Many businesses find data collection expensive and time-consuming. In reality, many businesses spend too many resources on trying to manually record the data and have no time to focus on what matters the most: achieving carbon reduction targets by reducing emissions for good.

This is why Net0 believes that putting carbon accounting on autopilot is essential for modern businesses. By using powerful AI-driven tools, Net0 automates data capture, ensures data quality, connects ERP, CRM and other systems with organisations' out-of-the-box integrations and offers API access to developers. Net0 convert business data to CO2e metrics automatically, with minimal effort from the team.

Complex process

Calculating carbon footprint can be complex, as there are different methodologies for doing so. It can be difficult to understand the different methodologies, choose the right one for your business and effectively implement them.

Net0’s platform helps businesses simplify the process by offering all three carbon accounting methods and finding the right one to use depending on each case. Whether your business chooses the activity-based approach, the spend-based method or the hybrid one, Net0 will support you throughout the process, helping you to accurately calculate emissions and achieve your net zero emissions targets.

Other challenges

Once businesses are done with the first step of measuring carbon footprint, organisations might face more challenges with carbon management on the way to carbon neutrality and then net zero. Some of them might include challenges with reducing corporate carbon footprint, reporting carbon emissions in real-time and sharing the journey transparently with other stakeholders in the ecosystem. Net0 also helps to tackle these challenges by offering a range of solutions that make carbon management easy and transparent.

The current state of carbon accounting in corporations

In general, carbon accounting is still in its early stages, and businesses are just starting to come to grips with the requirements of reporting Scope 3 emissions.  With rising expectations from consumers, governments and investors, companies are increasingly taking active steps to reduce emissions. Some businesses are also considering purchasing carbon offsets with carbon credits for unavoidable emissions in the short term. Although purchasing carbon credits is not a long-term solution, it is nevertheless a step towards companies’ climate goals.

The earlier your business starts carbon accounting, the more competitive you will be in today's market. Net0 can help you get ahead of the curve when it comes to carbon accounting, by providing an integrated platform to collect, manage and report your emissions data.

Carbon accounting in corporations

To comply with laws and regulations it is becoming the norm globally to report scope 1 and 2 emissions at the very least. Scope 3 value chain emissions are being reported now amongst value chains that want to decrease their negative environmental impacts and stay competitive where consumers are turning to greener brands. Another motivation is that investors have been shifting their resources only to sustainable brands. In fact, the demand for ESG investment options has been escalating for years according to a study by the Harvard Business Review.

What are the GHG emissions accounting standards?

It is important for businesses to be aware of the most common reporting standards.

The GHG Protocol

The Greenhouse Gas Protocol is a set of guidelines for calculating a carbon footprint. It was developed by the World Resources Institute and the World Business Council for Sustainable Development. The GHG Protocol helps companies and governments to track emissions and make informed decisions about reducing them.

The GHG Protocol has two tracks: the corporate track and the national inventory track. The corporate track is for companies that want to measure and manage their carbon footprint. The national inventory track is for governments that want to compile national greenhouse gas inventories.

The Greenhouse Gas Protocol is the most widely used climate accounting standard in the world. More than 1,500 companies and government agencies use it to measure and manage their carbon footprint. The GHGP is the perfect guide to understanding how to manage your GHG emissions.

Net0 complies with all GHGP standards since it is the most commonly used method.
