By proactively addressing their greenhouse gas emissions from their own operations and wider value chain, companies can create a positive impact on the environment and society.

Key Concepts: Greenhouse Gases, Carbon Footprint, and Net Zero

Understanding the key concepts of greenhouse gases, carbon footprint, and net zero is vital to effectively tackle carbon emissions.

Greenhouse gases are substances that absorb and emit infrared radiation, trapping heat in the Earth’s atmosphere and contributing to the phenomenon known as the greenhouse effect. The primary greenhouse gases are:

• Carbon dioxide (CO2)

• Methane (CH4)

• Nitrous oxide (N2O)

• Water vapour

These gases are emitted from various sources, including the combustion of fossil fuels, deforestation, agricultural activities, and industrial processes.

A carbon footprint is a measure of the total amount of greenhouse gases emitted by an individual, organisation, or product over a given period of time. It is typically quantified in metric tons of carbon dioxide equivalent (CO2e).

Net zero is a goal of achieving equilibrium between emissions and removals of greenhouse gases, meaning that the amount of emissions discharged into the atmosphere is equivalent to the amount of emissions eliminated from the atmosphere. By understanding these key concepts and their relationship to carbon emissions, organisations can develop targeted strategies to reduce their greenhouse gas emissions and work towards becoming carbon neutral, contributing to a more sustainable future.

Greenhouse Gases

Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and water vapor, trap heat in the Earth’s atmosphere, leading to global warming and climate change. The primary sources of greenhouse gas emissions are the combustion of fossil fuels, deforestation, agricultural activities, and industrial processes. The consequences of greenhouse gas emissions include global warming, sea level rise, ocean acidification, and extreme weather events.

Organisations can curb greenhouse gas emissions by employing renewable energy sources, improving energy efficiency, and reducing deforestation.

Carbon Footprint

A carbon footprint is a metric that quantifies the total greenhouse gas emissions attributed to an organisation, event, or product. The GHG Reporting Protocol - Corporate Standard is a widely recognised independent standard for calculating emissions.

Reporting and understanding their carbon footprint allow organisations to pinpoint areas for improvement and formulate strategies to curtail their greenhouse gas emissions.

Net Zero

Net zero is defined as attaining equilibrium between the volume of greenhouse gas emissions released and the quantity eliminated from the atmosphere. Achieving net zero can be accomplished through a combination of emission reduction and carbon removal augmentation. This includes implementing energy efficiency measures, utilising renewable energy sources, and optimising supply chain management.

Net zero can facilitate the mitigation of climate change effects, enhance air quality, and generate economic opportunities. By striving for net zero, organisations can contribute to global efforts in combating climate change and securing a sustainable future.

Understanding Scope 1, 2, and 3 Emissions

An effective approach to tackling carbon emissions entails a thorough understanding of Scope 1, 2, and 3 emissions, which classify a company’s direct and indirect emissions. The Greenhouse Gas Protocol provides a widely recognised framework for calculating and reporting these emissions. By understanding the different emission scopes, organisations can identify reduction opportunities and develop targeted strategies to lower their carbon footprint.

Scope 1, 2, and 3 emissions represent:

1. Direct emissions from sources owned or controlled by the entity

2. Indirect emissions resulting from the procurement and utilisation of electricity, steam, heating, and cooling

3. All indirect emissions that occur in the upstream and downstream activities of an organisation

Scope 3 emissions, also known as value chain emissions, typically account for the majority of an organisation’s overall greenhouse gas (GHG) emissions. By addressing all three scopes, companies can systematically work towards reducing their carbon emissions and contribute to global sustainability efforts.

Scope 1: Direct Emissions

Scope 1 emissions encompass direct emissions from sources owned or controlled by an organisation, such as emissions from burning fuel in owned or managed boilers and vehicles. Organisations can demonstrate their commitment to sustainability and directly mitigate their greenhouse gas emissions by identifying and reducing these emissions.

Implementing energy efficiency measures and transitioning to low-carbon fuels are some strategies to reduce Scope 1 emissions.

Scope 2: Indirect Emissions from Energy Use

Scope 2 emissions consist of indirect greenhouse gas emissions resulting from the purchase of electricity, steam, heat, or cooling. These emissions typically occur when an organisation consumes purchased electricity, heat, steam, and cooling. By understanding their Scope 2 emissions, organisations can identify opportunities to reduce these emissions through energy efficiency measures, renewable energy procurement, and demand-side management.

Scope 3: Indirect Emissions from Value Chain Activities

Scope 3 emissions encompass all indirect emissions that occur in the upstream and downstream activities of an organisation, which are not directly controlled by the organisation but are indirectly responsible for them. Examples of Scope 3 emissions include business travel in private cars and emissions from suppliers and partners.

Addressing Scope 3 emissions can be more challenging due to their complexity and the need for collaboration with suppliers and other value chain partners. However, by engaging with their value chain and implementing strategies such as:

• Supplier engagement programs

• Supply chain optimisation

• Product design for sustainability

• Use of renewable energy sources

• Carbon offsetting initiatives

Organisations can effectively address and reduce their Scope 3 emissions.

Strategies for Reducing Carbon Emissions

Various strategies, including energy efficiency measures, renewable energy sources, and supply chain management, enable companies to reduce carbon emissions. Implementing these strategies can not only help organisations reduce their carbon footprint but also improve their reputation, reduce costs, and comply with regulatory requirements.

Organisations can methodically reduce their carbon emissions and contribute to global sustainability efforts by amalgamating these strategies and addressing all three scopes of emissions. This not only benefits the environment but also allows businesses to remain competitive and resilient in an increasingly eco-conscious world.
