Net Zero Construction Explained

Sustainability has become one of the most important priorities for construction companies in the UK. With growing concerns about the impact of climate change, the sector has been introduced to stricter environmental regulations to ensure it keeps its carbon footprint as low as possible.

This has led to a big focus on Net Zero construction, which aims to minimise greenhouse gas emissions throughout the lifecycle of new buildings or structures.

Here at Contractwise, we help construction businesses nationwide with CIS compliance, but we also understand that the industry is responsible for a substantial proportion of the UK’s carbon emissions. With this in mind, we’ve put together this comprehensive guide to Net Zero in construction, helping you understand everything you need to know.

What is Net Zero?

Net Zero refers to achieving a balance between greenhouse gases emitted into the atmosphere and those that are removed from it. In simple terms, it means not adding any more carbon emissions to the atmosphere compared to what you take out and helping to reduce your carbon footprint as much as possible.

The term was first coined by scientists in 2005, but was officially introduced as a concept following the United Nations Climate Change Conference in Paris in 2015. Known as the Paris Agreement, this was a ruling that brought countries from around the world together with the shared goal of limiting global warming and keeping temperature increases below 1.5℃.

In construction, Net Zero means designing, building and operating structures in a way that keeps carbon emissions to a minimum.

The UK’s Net Zero 2050 target

The UK has positioned itself as a global leader when it comes to climate change action. Through the Climate Change Act 2008, the UK became the first major economy in the world to establish legally binding targets to reduce greenhouse gas emissions.

In 2019, this legislation was amended to include the target of achieving Net Zero by 2050; the European Union followed suit in 2021. This means that by the midpoint of the century, the country must remove or offset all carbon it emits.

The construction industry has a key role to play to meet this target, with experts estimating that all new buildings will need to be constructed to Net Zero standards to achieve these climate objectives.

Furthermore, the UK also needs to retrofit around 29 million buildings to improve insulation and introduce low-carbon technologies. 

 

What is Net Zero construction?

Net Zero construction refers to all construction practices and activities that offset carbon emissions. In the same way that Net Zero in general refers to striking this balance of greenhouse gases, Net Zero construction is about doing this specifically in the construction sector.

There are a wide range of benefits to Net Zero construction, including:

• Reduced environmental impact: Undoubtedly, the biggest advantage of Net Zero in construction is that carbon emissions are minimised, combating climate change and reducing pressure on natural resources.
• Lower energy costs: Net Zero buildings are designed to maximise energy efficiency. Better insulation and energy systems can significantly reduce energy usage, which helps to lower bills.
• Regulatory compliance: Environmental regulations are becoming increasingly stringent, and investing in proper Net Zero standards now will help you stay ahead of future requirements.
• Enhanced business reputation: Companies that embrace sustainable construction demonstrate environmental responsibility. This can strengthen brand reputation and is appealing to customers who may be more environmentally conscious.

How to make construction better for the environment?

Despite its obvious advances in recent years, the construction industry remains one of the biggest polluters due to the greenhouse gases the sector produces. In particular, the production of materials like steel and cement is known to release harmful carbon dioxide.

So, how can you ensure your construction activities help to meet Net Zero targets?

Embrace innovative materials

Traditional construction materials, like concrete and steel, have significant carbon footprints. Despite their widespread use, the industry is increasingly investigating low-carbon alternatives like engineered products and bio-based materials. While we are a long way off from seeing these materials become commonly used, in the future, this innovation could dramatically reduce carbon emissions.

Modular construction

Modular construction involves manufacturing building components off-site before they are brought to the final location. This approach helps to reduce material waste, improve quality control and minimise transportation emissions.

Reduce and reuse

Construction, by its very nature, produces a lot of waste. Implementing strategies to reduce material consumption and reuse existing resources is a great way to lower environmental impact.

Deconstruct not demolish

Rather than completely demolishing a building and sending all the waste material to landfill, deconstruction allows valuable materials and components to be recovered and then reused in the future. This approach supports a circular economy as it extends the life of building materials and reduces the demand for new resources.

Source locally

Transporting materials over long distances is one of the biggest contributors to high carbon emissions. Wherever possible, contractors should try to source materials locally, as this will reduce transport costs as well as supporting regional supply chains.

Improve energy efficiency

Energy efficiency remains one of the most effective ways to reduce the overall environmental impact of a building. From high-performance insulation to energy-efficient windows, there are all kinds of renewable energy systems that contribute to lower emissions.

Supporting Compliance in a Changing Construction Industry

As the construction industry transitions towards a Net Zero future, it is vital that businesses are compliant. Another important compliance consideration is the Construction Industry Scheme (CIS) that handles tax.

At Contractwise, we provide specialist CIS services, including payroll audits that protect contractors and subcontractors and eliminate the risk of HMRC reclassification that can be hugely damaging. Our experienced team will handle everything to ensure you’re always fully compliant and allow you to focus on delivering the best results for your customers.

Whether you work for a large-scale construction firm or are a small business trying to get to grips with tax complexities, we’ll tailor our offering specifically to your needs. For more information, contact our team today.
