In recent years, the term “net zero” has become a buzzword in discussions about climate change and sustainability. Governments, corporations, and individuals alike are setting ambitious targets to achieve net zero emissions.

However, there are several myths and misconceptions surrounding this concept. We have asked some of our Energy Consultants to debunk the most common myths and shed light on the reality of achieving net zero.

Myth 1: Net zero means zero emissions

by Timothy Holman, Head of Consultancy

One of the biggest misconceptions is that net zero means eliminating all emissions. In the UK, net zero has a clear legal definition under the Climate Change Act 2008 (2050 Target Amendment) Order 2019. It means cutting greenhouse gas emissions by at least 100% compared to 1990 levels by 2050.
In reality, net zero refers to balancing the amount of greenhouse gases emitted with the amount removed from the atmosphere. This involves drastically reducing emissions at the source and addressing only residual emissions, those that are unavoidable, with offsetting measures. Residual emissions are expected to account for no more than 10% of total emissions.

Working towards net zero is all about creating a balance while striving for a more sustainable future.

Myth 2: Net zero is only about carbon

by Sophie Legg, Data Analyst

While carbon dioxide is the primary greenhouse gas contributing to global warming, net zero encompasses a range of greenhouse gases, including methane (CH₄), nitrous oxide (N₂O), and fluorinated gases, such as hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs). These gases vary in their sources and warming potential but collectively impact climate stability.

Achieving net zero requires addressing emissions from sectors such as agriculture—where methane emissions stem from livestock; industry—producing nitrous oxide and fluorinated gases through manufacturing processes; transportation—primarily emitting carbon dioxide from fossil fuel combustion; and energy production from fossil fuels (coal, oil, and natural gas). Effective strategies to mitigate these emissions involve reducing reliance on fossil fuels, enhancing efficiency in industrial and agricultural practices, transitioning to renewable energy sources, and investing in carbon capture technologies to offset any residual emissions.

All sectors play a significant role in the UK’s greenhouse gas emissions profile, and targeted strategies are essential to mitigate their impact.

Myth 3: Net zero is too expensive

by Sam Arje, Senior Energy Consultant

Many believe that achieving net zero is prohibitively expensive. However, the costs of inaction—rising global temperatures, extreme weather events, and disrupted supply chains—are far greater. Investing in sustainable practices and technologies is not only essential for addressing these risks but can also result in long-term savings and economic opportunities. For businesses, aligning with climate mitigation plans such as adopting renewable energy, improving efficiency, and integrating low-carbon technologies can enhance resilience and competitiveness.

Additionally, there are incentives, grants, and funding available to support the transition to net zero. Organisations are further encouraged to be guided by frameworks like the Task Force on Climate-related Financial Disclosures (TCFD), which requires organisations to report on their climate-related risks and strategies. By aligning with TCFD requirements, organisations can demonstrate accountability, attract investment, and better position themselves for future regulatory changes. Proactively transitioning to net zero is not just a moral imperative—it is a smart and forward-thinking business strategy.

Myth 4: Net zero is only for big corporations

by Tom McLeish, Energy Consultant

Net zero is not an ambition reserved for large corporations; smaller businesses play a crucial role in contributing to this global goal. Simple actions, such as embracing energy efficient measures, and prioritising sustainable goods and services, collectively drive meaningful change.

These efforts also create ripple effects throughout the supply chain – which can account for up to 90% of an organisation’s total carbon emissions. Therefore, suppliers and smaller businesses can play a vital role in a large corporations’ carbon reduction and the success of its net zero goals. By implementing carbon reduction plans, small businesses prove their commitment and secure their future within the supply chain. Achieving net zero requires collective commitment from all sectors, where even seemingly small contributions add up to create substantial environmental impact.

Myth 5: Net zero is a distant goal

by Georgina Wisby, Energy Consultant

Some people think that net zero is a goal for the distant future. As of 2024, 147 out of 198 countries worldwide have established some form of net zero target. The UK’s target is to achieve net zero by 2050 or even earlier, in some cases 2030. Depending on where you are as an organisation, 25 years is not as far away as you think.

Reducing carbon emissions is undoubtedly a complex and challenging undertaking that will reveal bumps in the road, but it is an essential step in addressing the climate crisis. Gaining a clear understanding of the different types of emissions, harnessing near real-time data, engaging stakeholders, and fostering collaboration across the supply chain, can take time. But organisations can take meaningful strides toward their sustainability goals once the first steps are made. By adopting sustainable practices now and utilising effective tools to drive change, we can collectively accelerate the journey toward achieving net zero and create a more resilient, sustainable future.

Final thoughts

Achieving net zero is a complex but necessary goal to combat climate change. By understanding and debunking these myths, we can better appreciate the efforts required and the benefits of reaching net zero. It is a collective responsibility that involves governments, businesses, and individuals working together to create a sustainable future.
