The Climate Change Committee’s report A Well-Adapted UK examines the UK’s preparedness for a changing climate. This blog provides an overview of the report and considers what its findings on climate adaptation mean for major projects.

Climate adaptation is now a project imperative

The Climate Change Committee’s May 2026 report A Well-Adapted UK presents a clear message: climate change is no longer a future challenge – it is already affecting how we live, work and deliver projects across the UK.

While reducing greenhouse gas emissions remains essential, the report highlights that adaptation must now receive equal attention. Even with continued progress towards Net Zero, some climate impacts are unavoidable. The question is no longer whether we need to adapt, but whether we are adapting quickly enough.

For those involved in delivering major projects, this has significant implications for how infrastructure is planned, designed and managed.

Key themes from the report

1. Climate impacts are already being felt
The UK is experiencing increasingly frequent and severe weather events, including heatwaves, flooding, drought and coastal erosion. These changes are placing growing pressure on infrastructure, public services, businesses and communities.

Major projects delivered today will operate in a very different climate over their lifetime. Designing assets based solely on historic weather patterns is no longer sufficient.

2. Adaptation must sit alongside decarbonisation
Much of the conversation around climate change has focused on reducing emissions. The report makes it clear that this alone will not be enough.

Projects must not only contribute to Net Zero but also be resilient to future climate conditions. This means considering how assets will perform during extreme weather, prolonged heat, water shortages and changing environmental conditions.

3. Investing early reduces long-term risk
The report argues that proactive investment in climate resilience is significantly more cost-effective than responding to the consequences of climate impacts after they occur.

Embedding resilience during planning and design can help avoid costly retrofits, reduce disruption and improve the long-term value of infrastructure investment.

4. Resilience should be embedded throughout the project lifecycle
Climate adaptation should not be treated as a standalone exercise. Instead, resilience should be considered throughout project development, from business case and design through to construction, operation and maintenance.

This includes understanding future climate risks, reviewing assumptions, building flexibility into designs and considering the long-term performance of assets.

5. Leadership will be critical
Perhaps the strongest message throughout the report is that the knowledge already exists. The challenge is turning ambition into delivery.

Strong leadership, clear governance and collaboration across organisations will be essential to ensure climate adaptation becomes business as usual rather than an afterthought.

What this means for major projects

For project leaders and sponsors, the report reinforces several important considerations:

• Design infrastructure for future climate conditions, not historical ones.
• Embed climate resilience from the earliest stages of project development.
• Balance carbon reduction with long-term resilience and adaptation.
• Recognise climate risk as a strategic project risk alongside cost, schedule and safety.
• Invest early to reduce whole-life costs and improve long-term asset performance.
• Encourage collaboration across sectors to share learning and strengthen resilience.

Why this matters

The Climate Change Committee’s report provides a timely reminder that adapting to climate change is no longer optional, it is fundamental to delivering successful, resilient infrastructure.

For the major projects community, climate adaptation is not simply an environmental issue. It is about delivering projects that remain safe, reliable and fit for purpose throughout their operational life.

As the climate continues to change, embedding resilience into decision-making today will help ensure the UK’s infrastructure is better prepared for tomorrow.
