Climate change and the construction industry – stay ahead and avoid risk


11th November 2024

As global efforts to combat climate change accelerate, the construction industry stands at a critical crossroads, with new regulations being offered with both unprecedented opportunities and challenges.

Wales Climate Week (11-15 November 2024) presents a timely opportunity to explore how the construction industry can play a pivotal role in reducing carbon emissions. With the UK’s construction industry being responsible for 25% of the nation’s greenhouse gas emissions, decarbonising this sector is essential to achieving net-zero targets. The introduction of the NEC contract’s groundbreaking X29 clause makes this ambition more achievable than ever. Released in July 2022, this update to the NEC4 suite is the first to directly address climate change, marking a significant step forward in sustainable project delivery. However, while NEC’s X29 clause offers powerful tools to drive decarbonisation, it also introduces risks that clients must carefully manage.

The role of climate change requirements in construction contracts

Option X29 formalises climate commitment by integrating a comprehensive set of Climate Change Requirements (CCR). These CCRs focus on key areas, including on-site recycling, the use of renewable energy, minimising waste, and promoting eco-friendly designs. By embedding these CCRs into construction projects, companies are not only fulfilling their global climate obligations but also enhancing their brand reputation by aligning with growing consumer and stakeholder demand for eco-conscious practices.

However, while the advantages are clear, Option X29 also carries inherent risks if not managed effectively. Under Clause 20.1, contractors are obligated to provide work in accordance with the project’s scope, including compliance with the CCRs. Any failure to meet these requirements constitutes a breach of contract. Should a failure be identified, it is treated as a defect that the contractor must rectify. This places significant pressure on contractors to meet rigorous environmental standards. If they fall short, they face financial penalties, which could cause possible project delays. This underlines the need for careful planning to ensure that the CCR requirements are achievable and do not place undue risks on any of the parties involved.

Incentivising green performance: unlocking the potential of the Performance Table

A key innovation within Option X29 is the introduction of the Performance Table, which empowers clients to set financial incentives that motivate contractors to meet or exceed key sustainability targets. This structure not only keeps environmental goals at the forefront of construction projects but also creates a reward system where achieving green objectives results in tangible financial benefits for all parties involved.

However, it is important to recognise the financial risks as well. If the contractor fails to meet the targets outlined in the Performance Table, they may be required to compensate the client. On the flip side, achieving or surpassing these targets entitles the contractor to financial incentives, to be funded by the client. Moreover, any payments owed by contractors are treated as excluded matters from the cap on liability, particularly when secondary Option X18 is applied. Contractors, therefore, must consider these obligations carefully, as they can affect professional indemnity insurance policies and the overall risk profile of the project.

The road ahead for the construction industry

As climate action accelerates, Option X29 provides a powerful tool for the construction industry to lead the charge in reducing carbon emissions. Yet, with these opportunities come responsibilities — both clients and contractors must take care to ensure that the Climate Change Requirements and Performance Tables are carefully tailored to promote sustainable practices without introducing undue financial or legal risk.
