The Differences Between Carbon Neutral and Net Zero

While businesses have become familiar with climate-related terminology in recent years, there is still some confusion surrounding key carbon neutral and net zero. This confusion is understandable — many people still use the terms interchangeably, but they actually refer to two different things. Understanding the difference between carbon-neutral and net zero claims, and how they relate to climate goals, is vital for businesses embarking on a climate action strategy. 

What is Carbon Neutral?

Carbon neutrality essentially means balancing the levels of carbon dioxide or greenhouse gases (GHGs) emitted into the atmosphere, with the levels of carbon absorbed by the atmosphere in carbon ‘sinks’.

In business, carbon neutrality is achieved when a company’s carbon emissions are counterbalanced by an equivalent amount being removed. What cannot be removed can be ‘offset’ by purchasing carbon offsets to achieve carbon neutrality. Carbon offsets, or offset units (or carbon credits) are created by projects that avoid, reduce, remove or capture greenhouse gas (GHG) emissions from the atmosphere such as planting trees or increasing carbon in soil.

Carbon sinks do most of the heavy lifting when it comes to removing carbon from the atmosphere. They are systems that absorb more carbon than they emit; think soil, oceans, and forests. Carbon sinks generally remove between 9.5 and 11 Gt of carbon each year.

In our industrialised, modern world, no natural carbon sink is able to remove enough carbon to combat the amount of carbon rapidly being emitted into the atmosphere. The consequence is the effects of climate change. 

The carbon stored in natural sinks, such as forests, can also be released back into the atmosphere due to unsustainable practices such as deforestation and wildfires.  

Offsetting Carbon Emissions

Offsetting refers to activities and practices that prevent, reduce, or remove carbon and other greenhouse gases from the environment. 

Offsetting strategies provide businesses with opportunities to reach their carbon neutral targets. One carbon offset equals one tonne of greenhouse emissions reduced. 

Businesses must ensure that the carbon offsets they purchase are credible. They must adhere to strict selection criteria in order to ‘count’ as a certified offset. 

For an offset to be considered credible, the removal of carbon must be permanent and licensed. 

Offsets are classified as either avoided emissions, which is preventing emissions from being released into the atmosphere — or sequestration, which is the act of physically removing or capturing existing emissions.

Examples of carbon offsets include tree planting, wind farm projects, energy efficiency projects, and investing in initiatives that reduce the methane output of cows. 

Projects that enhance biodiversity, improve soil quality, and maximise rainwater usage are also credible offsets.  

What is Net Zero?

Net zero refers to a company’s target goal to counterbalance all its greenhouse gas emissions with greenhouse gas removals by a certain time, for example, net zero by 2040. 

In order to reach their net zero goal, a business can implement a Science Based Target (SBT). A science-based target defines a pathway for companies to reduce their greenhouse gas emissions in line with climate science and the Paris agreement. 

The process of removing carbon from the atmosphere and storing it is called carbon sequestration. In order to achieve net zero emissions, all worldwide greenhouse gas emissions need to be counterbalanced by some form of carbon capture or carbon sequestration. 

To avoid the most extreme consequences of climate change and preserve a liveable planet, the Paris Agreement tells us we need to cut global emissions by 45% by 2030 and reach net zero by 2050.

Governments who are signatories to the Paris Agreement have set net zero targets in-line with the goals of the Agreement. 

What is Absolute Zero Emissions?

Absolute zero refers to the total absence of greenhouse gas emissions. 

What’s the Difference Between Carbon Neutral and Net Zero?

As we can see, carbon neutral and net zero are closely related terms, but they are not entirely interchangeable. 

Carbon Neutral vs Net Zero

The concepts of carbon neutral and net zero have some notable differences. 

As we know, ‘net zero emissions’ refers to achieving an overall balance between GHG emissions produced and GHG emissions taken out of the atmosphere. For corporations, this requires regular measurement of GHG emissions in line with a robust standard (for example, the Greenhouse Gas Protocol suite of standards), a reduction of emissions, and in most cases, the removal of or compensation for residual emissions. 

Net zero implies a connection to the Paris Agreement, which outlines the goal to “achieve a balance between anthropogenic emissions by sources and removals by sinks of GHG in the second half of the century”. We’ll take a closer look at the Paris Agreement below.  

Therefore, the general expectation is that a corporation’s net zero target supports the goals of the Paris Agreement and is governed by its underlying principles. 

Carbon neutrality, on the other hand, can be achieved today through carbon offsets. Operational emissions reduction is part of the process, but most standards or protocols for carbon neutrality don’t specify a minimum requirement on how much of a corporate carbon footprint must be reduced versus how much must be offset — the only requirement is that the final balance is zero. 

Examples for such protocols are the Climate Active Carbon Neutral framework in Australia, the British PAS 2060, and the ISO/WD 14068 Carbon Neutrality standard, which is still under development. 

The Paris Agreement

The Paris Agreement is the first legally binding, worldwide climate change agreement. It was first adopted by participating parties at the United Nations Climate Change Conference of Parties (COP21) in December 2015. 

It is a global framework outlining steps that need to be taken to prevent the worst effects of climate change. The Agreement endeavours to help strengthen each country’s ability to deal with the impacts of climate change and assists countries in these efforts. 

Currently, 193 parties have committed to the Paris Agreement.

The Paris Agreement aims to achieve global climate neutrality by 2050. Each signing Party is held accountable to the below elements.  

  • Reducing Emissions – The Agreement outlines that average global temperatures must sit well below 2°C above pre-industrial levels, with 1.5°C as the ideal target limit. Parties must undertake significant and rapid reductions in order to achieve a balance between carbon emissions and removals by 2050. 
  • Transparency – Participating parties agreed to meet every 5 years to assess their progress, provide updates, and enhance their strategies through a clear and transparent reporting system. 
  • Adaptation – Parties agreed to strengthen their community’s ability to deal with the realities of climate change and its impacts. They also commit to providing international support to developing countries.
  • Loss and Damage – Parties recognise the importance of minimising, addressing, and averting the damages and losses that arise due to the impacts of climate change. Parties must enhance their understanding, action, and support in early warning systems, risk insurance, and preparedness to deal with emergencies.
  • Cities, Regions, and Local Authorities – Non-governmental organisations and stakeholders play an important role in addressing climate change. The Agreement encourages cities, private sector businesses, and subnational authorities to enhance efforts to reduce emissions, increase resilience, and promote regional and international cooperation. 
  • Support – Developed countries are required to continue to support all climate action to reduce emissions, and assist developing countries in building resilience against the impacts of climate change. 

The Global Climate Action Agenda

Countries, cities, regions, businesses, and communities taking action to support the Paris Agreement outside of intergovernmental negotiations do so under the Global Climate Action Agenda.
