What Are Scope 1, 2 and 3 Emissions?

It is no longer an option to understand emissions for corporations; it is mandatory. If you are at the beginning of your carbon footprint path, or fine-tuning your reporting, the first thing you need to learn about is how emissions are classified.

Scope 1, 2, and 3 Emissions Explained

Here’s scope 1, 2 & 3 emissions explained:

It refers to a globally accepted approach used to categorise greenhouse gases (GHG) emissions according to their origin. The greenhouse gas protocol scopes are the basis for such categorization and help organisations to assess and minimize their environmental impact.

It means that there are three types of emissions:

Directly emitted by owned sources.

Indirectly emitted by sources related to purchased energy.

Emitted from outside the organization's value chain.

This categorisation enables companies to understand the source of their emissions.

What's the Difference Between Scope 1, 2, and 3?

It is essential to understand the difference between Scope 1, 2, and 3 when doing carbon accounting.

Scope 1 includes emissions that occur directly from operations under the control of the organisation.

Scope 2 includes emissions caused by indirect sources such as purchased energy.

Scope 3 encompasses all other indirect emissions in the value chain.

Whereas Scope 1 and Scope 2 are fairly simple, Scope 3 is much wider and often more complicated to quantify, as it covers everything from supplier activities to product usage.

Are Electricity Emissions Scope 2 or 3?

Emissions due to electricity will often be categorised as Scope 2 emissions electricity since such emissions emanate from energy purchased and used by an organisation.

There will be instances, however, when some emissions related to electricity can be categorised under Scope 3. These are particularly those related to the production and transmission of energy. Nevertheless, for many organisations, electricity will remain under the Scope 2 category.

Which Scope Is the Hardest to Reduce?

Scope 3 emissions business activities are the most difficult for companies to manage since it deals with third-party involvement of suppliers, logistics partners, and even customers.

On the other hand, Scope 1 and 2 are easier for companies to handle because they have direct control; Scope 3 needs cooperation, transparency, and engagement through the entire value chain.

Do Businesses Have to Report All Three Scopes?

Not all corporations are obliged by law to disclose all their scopes, but there is an increasing trend of voluntarily doing so or because of external pressure from stakeholders.

In Australia, the National Greenhouse and Energy Reporting (NGER) system focuses on Scope 1 and Scope 2 more than anything else. Yet some progressive businesses, assisted by companies such as Agile Energy, are going beyond those and including Scope 3 in their reports.

Scope 1: Direct Emissions: Fuel Combustion, Company Fleet & Refrigerants

Scope 1 emissions refer to emissions that result directly from sources that are owned or controlled by a business. Examples of such emissions include:

Burning of fuel in boilers, furnaces, or generators.

Emission from company-owned vehicles.

Release of refrigerants from the cooling system.

Such emissions tend to be easier to quantify since they occur internally. Reduction can be achieved through clean fuels or the electrification of fleet vehicles.

Scope 2: Indirect Emissions: Purchased Electricity, Heating & Cooling

Scope 2 emissions are associated with the energy that an organisation acquires. These include:

Electricity from the power grid

District heat and cooling

Due to the relationship between these emissions and the use of energy, there is a great potential for emission reductions. Organisations are increasingly embracing sustainable business energy solutions to reduce dependence on fossil fuel electricity.

Scope 3: Value Chain Emissions: Suppliers, Transportation, Business Travel, Waste & Other Indirect

Scope 3 emissions include all activities within the complete value chain, which are as follows:

Buying of goods and services

Transportation and distribution

Commuting by employees and business travels

Disposal of waste

Utilisation of sold products

Due to the massive number of emissions generated under Scope 3, these emissions become a major part of the carbon footprint of companies.

Why Scope 2 Is Often the Easiest First Win

Of all the categories, Scope 2 is usually the simplest to decrease. Companies can make changes right away by switching to green power or enhancing energy efficiency.

For instance, installing industrial solar panels or using a commercial solar system Melbourne option enables organizations to reduce their carbon footprint quickly. This is one of the reasons why many companies focus on reducing Scope 2 right at the beginning.

Moreover, such actions pay off really fast financially due to lower utility bills and other benefits, which makes this a win-win situation for environmentalists and budget planners.

How Solar and Renewables Cut Scope 2

Renewable energy is a key aspect when it comes to tackling Scope 2 emissions. This could take several forms, including:

Solar panel installation on site

Power Purchase Agreements (PPAs)

Battery storage technology

Off-grid renewable energy

Ground-mounted solar PV panels would be very helpful for businesses that have large landmasses, and commercial off-grid solar panels will offer independence from conventional power grids.

Organisations, such as Agile Energy, are well placed to help organisations achieve their goal of reduced carbon emissions.
