Carbon neutrality vs net zero: unravelling the key differences

In recent years, “carbon neutrality” and “net zero” have become increasingly important in environmental sustainability and climate change discussions.

While these concepts are often used interchangeably, it’s essential to understand their subtle yet significant differences to appreciate their impact on global climate goals and how to achieve them.

Carbon neutrality means balancing the release of carbon dioxide emissions with an equivalent amount of carbon credits.

  • This can be done by supporting carbon-reducing projects and initiatives.
  • The approach doesn’t require reducing emissions at the source as long as the emissions released are offset elsewhere.

On the other hand, net zero focuses on reducing greenhouse gas emissions per the latest climate science and compensating for residual emissions through carbon removal initiatives.

  • This approach involves not only carbon dioxide but also other greenhouse gases.
  • It engages the entire supply chain of a company or entity in the emissions reduction effort.

While both strategies aim to mitigate climate impacts, net zero represents a more comprehensive and challenging path. It seeks to reduce emissions, including a broader range of greenhouse gases.

It aims to align better with global climate targets such as the 1.5 degrees Celsius trajectory outlined in progressive climate frameworks.

Companies and governments increasingly recognise and adopt the net zero goal to demonstrate their commitment to a more sustainable and environmentally responsible future.

Differences between carbon neutral and net zero

Carbon neutrality

Carbon neutrality is a term used to describe how an entity’s emissions, such as an organisation or country, are balanced by an equal amount of carbon dioxide removed from the atmosphere.

This balance can be achieved by reducing or offsetting emissions by purchasing carbon credits or supporting renewable energy projects.

However, it’s important to note that carbon neutrality mainly focuses on carbon dioxide (CO2) emissions and not other greenhouse gases in its calculations.

Some ways to achieve carbon neutrality include:

  • Implementing energy efficiency measures
  • Using renewable energy sources, such as solar or wind power
  • Participating in reforestation projects or other initiatives that remove CO2 from the atmosphere

Key points about carbon neutrality:

  • Targets CO2 emissions
  • May cover only part of business operations
  • Doesn’t require actual emissions reductions

Net zero

The critical difference between carbon neutrality and net zero is that achieving net zero requires all GHG emissions to be reduced and balanced, not just CO2.

This may require additional efforts or technologies, such as capturing and storing methane or reducing the levels of nitrous oxide produced by agriculture.

Strategies to work towards net zero can include:

  • Reducing emissions from all sources of greenhouse gases
  • Supporting projects that capture and store other greenhouse gases besides CO2
  • Moving to more sustainable practices, such as sustainable agriculture or manufacturing

Key points about net zero:

  • Targets all greenhouse gas emissions
  • Considers the entire value chain
  • Requires actual emissions reductions

The ultimate objective of both carbon neutrality and net zero is to address the climate crisis by lessening the impact of greenhouse gas emissions. This includes carbon dioxide (CO2) and other gases like methane or nitrous oxide.

Organisations are encouraged to adopt these objectives as part of their sustainability plan as they strive to decrease their environmental impact and participate in the fight against climate change.

Achieving climate targets: key concepts

The illustration portrays a visual representation of an environment with trees, a factory symbolizing industry, and vehicles symbolizing transportation emitting CO2.  The representation of the environment signifies the natural surroundings and ecosystems. The factory symbolizes industrial activities, and the vehicles represent transportation emissions. CO2 is visually depicted as emissions from these sources.  The illustration aims to visually communicate the concept of CO2 emissions from industrial and transportation sectors, highlighting their impact on the environment and contributing to climate change. It underscores the need for sustainable practices and efforts to reduce carbon emissions in these sectors for a healthier and more sustainable planet.

Carbon offsetting

Carbon offsetting allows entities to compensate for their greenhouse gas emissions by investing in projects that reduce emissions elsewhere.

Examples include reforestation, renewable energy initiatives, and methane capture on landfills. Organisations seeking carbon neutrality often use carbon offsetting as they cannot eliminate all their emissions.

Carbon capture and storage

Carbon capture and storage (CCS) involves capturing carbon dioxide (CO2) at the source, such as a power plant, and storing it safely underground in geological formations.

This helps to reduce greenhouse gas emissions by preventing CO2 from being released into the atmosphere. CCS is a crucial tool in achieving net zero emissions.

Direct air carbon capture and storage

Direct air carbon capture and storage (DACCS) captures CO2 directly from the atmosphere instead of catching it at the source of emissions.

This method provides a way to remove CO2 that has already been emitted, which can help achieve net zero targets. DACCS often involves using chemical processes to absorb and release captured CO2, which can then be securely stored.

Energy efficiency

Increasing energy efficiency is vital to achieving carbon neutrality and net zero goals. Energy-efficient technologies and practices can be implemented in various sectors, such as transportation, industry, and buildings.

Some examples of increased efficiencies include:

  • Designing energy-efficient buildings with better insulation and natural lighting
  • Implementing energy management systems in industrial processes
  • Encouraging the use of public transport or electric vehicles for transportation

By focusing on carbon offsetting, carbon capture and storage, direct air carbon capture and storage, and increased efficiencies, entities can make significant progress towards achieving their carbon neutrality or net zero emission targets.

Global efforts and agreements

The Paris Agreement

The Paris Agreement is a global effort to combat climate change by reducing greenhouse gas emissions.

The agreement, adopted in 2015, aims to limit global warming to 1.5 degrees Celsius above pre-industrial levels. It calls for a reduction in emissions by 45% by 2030 and reaching net zero by 2050.

The terms “carbon neutrality” and “net zero” come into play in this context. Carbon neutrality offsets the amount of carbon emissions, while net zero refers to achieving a balance between greenhouse gases emitted and removed from the atmosphere.

Country commitments

Several countries have made significant commitments to carbon neutrality and net zero goals.

  • France: As a leader in the Paris Agreement process, France has committed to becoming carbon neutral by 2050. They plan to achieve this by investing in renewable energy, promoting eco-friendly transportation, and supporting reforestation efforts.
  • United Kingdom: The UK has set a legally binding target of reaching net zero emissions by 2050. They aim to transition away from fossil fuels, invest in renewable energy, and promote low-carbon transportation, among other measures.
  • New Zealand: New Zealand is committed to achieving climate neutrality by 2050. Their approach strongly focuses on reducing methane emissions from agriculture, investing in renewable energy, and supporting climate-resilient communities.

Each of these countries and others participating in the Paris Agreement contributes to the global effort to halt climate change and protect the environment for future generations.

The combination of carbon neutrality and net zero efforts demonstrates a proactive approach to addressing the pressing issue of global warming.

Businesses and stakeholders

The illustration symbolizes the idea that companies are increasingly setting net zero targets to align with the Paris Agreement and contribute to global efforts. The industry emitting smoke represents traditional practices that contribute to carbon emissions. The presence of the big businessman signifies corporate responsibility and the proactive steps taken by companies to reduce their carbon footprint. By clearing the smoke, it symbolizes their commitment to mitigating climate change and aligning with the goals outlined in the Paris Agreement. The illustration visually communicates the growing trend of companies setting net zero targets, which involves reducing greenhouse gas emissions to a level where any remaining emissions are offset or removed from the atmosphere. It reflects the recognition of businesses to address climate change and play a role in global sustainability efforts.

Companies transitioning to net zero

Regarding sustainability, businesses and stakeholders often compare carbon neutrality and net zero.

Companies are increasingly setting net zero targets to align themselves with the Paris Agreement and contribute to the global effort to limit temperature rises below 2 degrees Celsius. To achieve net zero, businesses:

  • Calculate their greenhouse gas emissions across all scopes (scopes 1, 2, and 3)
  • Set science-based targets to reduce emissions where possible
  • Offset any remaining emissions by investing in certified projects, such as renewable energy or reforestation efforts

Value chain considerations

The value chain represents the range of activities a business undertakes to move its products or services from conception to delivery. Net zero efforts require consideration of emissions generated across this entire chain. This includes:

  • Emissions from direct operations (scope 1)
  • Emissions from purchased electricity, heat, and steam (scope 2)
  • Emissions from upstream and downstream activities, such as raw material sourcing, transportation, and product disposal (scope 3)

Fulfilling net zero commitments often requires collaboration with suppliers, customers, and other stakeholders in the value chain to create a comprehensive approach towards emissions reduction. Businesses may consider the following strategies to decrease emissions across the value chain:

  • Implementing energy-efficient technologies
  • Switching to renewable energy sources
  • Encouraging sustainable practices among suppliers
  • Reducing waste and improving resource efficiency
  • Investing in carbon offset projects

Achieving net zero is a collective effort that extends beyond individual organisations. By considering the entire value chain and working together with other businesses and stakeholders, companies can contribute to a more sustainable future.

Challenges and opportunities

Reducing carbon dioxide emissions

One of the primary differences between carbon neutrality and net zero is the focus on reducing CO2 emissions.

Because it considers all GHG emissions, achieving net zero requires more aggressive actions and a more comprehensive approach.

To reduce CO2 emissions, businesses and governments can invest in:

  • Renewable energy sources, such as solar and wind power
  • Energy efficiency improvements in buildings, transport, and industrial processes
  • Carbon capture and storage (CCS) technologies

These actions help minimise CO2 emissions and move us closer to the goal of net zero emissions. Reduced CO2 emissions contribute to combating climate change and have long-term economic and societal benefits.

Supporting ecosystems

Ecosystems play a vital role in maintaining the balance of greenhouse gases in the atmosphere, and their preservation is crucial in achieving net zero emissions. Healthy ecosystems, including forests, wetlands, and oceans, absorb and store CO2, thus mitigating climate change.

To support ecosystems and enhance their capacity to store CO2, the following actions can be taken:

  • Reforestation and afforestation, which increase the number of trees that absorb CO2
  • Restoration and preservation of existing forests, wetlands, and other ecosystems
  • Sustainable land management to prevent soil degradation and loss of carbon stocks

By implementing these strategies, we can harness the power of nature to help tackle climate change and reduce overall greenhouse gas emissions.

Summing up: carbon neutral vs net zero

While carbon neutrality and net zero shares a common objective of addressing climate change, their approaches differ significantly.

Carbon neutrality mainly focuses on CO2 emissions and can include only a specific portion of a company’s operations. On the other hand, net zero is more comprehensive, targeting all supply chain emissions, which makes it a more robust and ambitious climate action strategy.
