UK launches first-ever Climate Security Taskforce
Climate change and nature loss are no longer treated solely as environmental challenges. Increasingly, they appear in national security discussions. The UK government now considers them risks that could disrupt critical infrastructure, strain supply chains and destabilise international relations. Consequently, it has established a new expert body to address these threats directly.
This new taskforce brings together military advisers, geopolitical analysts, climate scientists and biodiversity specialists. The purpose is clear: to identify where the UK remains vulnerable and recommend how government can strengthen its resilience. For businesses, the implications extend beyond policy headlines. Infrastructure standards may change. Procurement expectations could tighten. Risk assessments may need to account for environmental pressures that affect operations, logistics and long-term planning.
Understanding what this taskforce does and why it exists helps clarify where business exposure to climate and nature risks may grow. It also signals how government thinking on security is evolving and where regulatory or strategic pressure may follow.
National security taskforce combines climate and nature threats
The government launched what it calls the world's first Climate and Nature Security Taskforce. Announced initially in June 2026, the body was formalised later that year as the National Security and Resilience Risks of a Changing Climate and Nature Loss Taskforce. Its inaugural meeting took place in October 2026, led by Climate Minister Katie White and Cabinet Office minister Baroness Fiona Twycross.
The taskforce was created to assess how climate change and biodiversity loss could affect national security. This includes risks to critical infrastructure, food and energy security, public safety and international stability. Minister Katie White described climate change as "no longer a distant concern" but rather "a security challenge that is reshaping the world in which we all live."
Unlike previous advisory groups, this one explicitly combines climate and nature. The reasoning is that ecosystem degradation weakens natural defences against flooding, undermines food systems and amplifies climate shocks. Meanwhile, climate change accelerates the decline of forests, wetlands, soils and biodiversity. Treating them separately risks missing how they interact and compound one another.
The taskforce includes experts from defence, energy, geopolitics, climate diplomacy and conservation. Members include General Richard Nugee, former Ministry of Defence non-executive director for climate change, and Professor Tim Benton, formerly of Chatham House. Others include Bassam Fattouh from the Oxford Institute for Energy Studies, Duncan Depledge from Loughborough University and Nathalie Pettorelli from the Zoological Society of London.
Additional members include Comfort Ero, President of the International Crisis Group, Erin Sikorsky from the Center for Climate and Security and Rosie Hails, Director of Science at the National Trust. This composition reflects the breadth of the challenge: climate-related security risks cross institutional boundaries and require interdisciplinary assessment.
Four priorities guide the taskforce's work
The government has set four objectives for the group. First, identify and prioritise the most significant climate and nature-related threats to UK and international security. Second, highlight gaps in existing government preparedness and resilience planning. Third, review and challenge current government work on climate-related security risks. Fourth, recommend opportunities for the UK to improve resilience and influence international outcomes.
The taskforce is expected to assess whether existing evidence is being translated into actionable policy. Therefore, its focus extends beyond identifying risks to determining which require immediate attention and what institutional responses are needed. This includes examining whether government departments are coordinating effectively and whether current planning reflects the severity and speed of environmental change.
Terms of reference provided for up to two meetings in 2026, one in person and one virtual. The expected output includes an assessment of gaps in government response, an evaluation of strategic approach and recommendations for further action. However, the limited initial timetable raises questions about how extensively the taskforce can evaluate complex and rapidly evolving risks.
The taskforce will make independent recommendations rather than directly implement policy. Consequently, its influence depends on whether ministers adopt its findings and integrate them into national security, infrastructure, defence, economic and international development planning. The group's impact will be measured not by its analysis alone but by whether government acts on its advice.
Why climate and biodiversity now count as security threats
Climate change and ecosystem degradation create security pressures through multiple pathways. Flooding, heatwaves, storms and wildfires can damage transport networks, energy systems, communications infrastructure and water supplies. When critical infrastructure fails, the economic and social consequences follow quickly.
Food and water insecurity presents another layer of risk. Climate impacts and biodiversity loss reduce agricultural productivity and increase pressure on global commodity markets. For the UK, which imports approximately half its food, disruption to international supply chains can affect availability and price. Extreme weather in key growing regions or transport corridors can have immediate effects on UK businesses and consumers.
Supply chain vulnerability extends beyond food. Extreme weather and ecosystem degradation disrupt the availability of raw materials, energy and industrial components. Businesses relying on global supply networks face increasing exposure to climate-related shocks in regions they may not directly monitor. Moreover, these disruptions often occur with little warning and limited opportunity for substitution.
Geopolitical instability can worsen when climate stress intensifies competition over land, water and resources. Fragile states may face additional pressure, potentially leading to conflict, migration or governance failures. For the UK, this creates risks to international stability, humanitarian obligations and trade relationships. Defence readiness is also affected: heat, flooding and environmental stress can impact military bases, logistics, equipment and overseas operations.
Migration and humanitarian emergencies linked to climate-related disasters place additional demands on governments and international organisations. Displaced populations require support, and prolonged displacement can strain regional stability. For businesses operating internationally or managing diverse supply chains, understanding these pressures helps anticipate where operational risks may emerge.
General Richard Nugee has welcomed an approach that places "climate change and biodiversity loss at the heart of National Security" for the UK. Janani Vivekananda said the taskforce could help ensure that the UK acts "early and decisively" through integrated, evidence-based responses that prevent climate and nature risks from becoming crises. These statements reflect the central challenge: moving from broad recognition of climate risk to early intervention before problems escalate.
What this means for UK businesses and operations
The taskforce's creation signals that climate and nature risks are moving from the periphery to the centre of government planning. For businesses, this shift has several implications. Firstly, infrastructure standards may change. If the government acts on recommendations to improve resilience, building codes, flood defences, energy systems and transport networks could face new requirements. Companies involved in construction, property management or infrastructure development should anticipate higher standards and different design expectations.
Secondly, procurement expectations are likely to tighten. Public sector buyers already consider carbon reduction and environmental impact. As climate security becomes embedded in national resilience planning, suppliers may face additional scrutiny on how they manage climate and nature-related risks. This could affect tender criteria, contract terms and ongoing supplier assessments. Businesses bidding for government work should prepare for more detailed questions about environmental vulnerability and resilience measures.
Thirdly, risk assessments may need to evolve. Traditional business continuity planning often focuses on immediate operational threats. However, climate and nature risks operate on different timescales and interact in complex ways. A heatwave can disrupt logistics, a flood can damage a supplier's facility, or biodiversity loss can undermine raw material availability. Consequently, businesses may need to broaden their risk frameworks to account for environmental pressures that affect operations indirectly.
Supply chain resilience will face greater scrutiny. Businesses that rely on international suppliers or operate in vulnerable regions should assess where climate and nature risks could disrupt their operations. This includes understanding exposure to extreme weather, water scarcity, ecosystem degradation and geopolitical instability linked to environmental stress. Companies that map these risks early can identify alternative suppliers, adjust contracts or invest in resilience measures before disruption occurs.
Financial and insurance markets are also responding. Insurers are increasingly factoring climate and nature risks into premiums and coverage terms. Lenders and investors are asking more detailed questions about environmental exposure and resilience. Businesses that demonstrate robust risk management and adaptation planning may find it easier to secure favourable financing terms and insurance coverage. Conversely, those that fail to address these risks may face higher costs or limited access to capital.
Regulatory expectations may also grow. While the taskforce itself does not create regulations, its recommendations could inform future policy. This might include mandatory climate risk disclosure, stronger environmental reporting requirements or new obligations for critical infrastructure operators. Staying ahead of these developments allows businesses to prepare rather than react, reducing compliance costs and operational disruption.
Essential facts about the taskforce and its role
- The Climate and Nature Security Taskforce was announced in June 2026 and formally established later that year as the National Security and Resilience Risks of a Changing Climate and Nature Loss Taskforce.
- Its inaugural meeting took place in October 2026, chaired by Climate Minister Katie White and Cabinet Office minister Baroness Fiona Twycross.
- The taskforce includes military, geopolitical, climate, energy and biodiversity experts, reflecting the cross-sectoral nature of climate and nature security risks.
- It is tasked with identifying the most significant threats, highlighting gaps in government preparedness, reviewing current work and recommending improvements to resilience and strategic advantage.
- The taskforce will make independent recommendations, meaning its impact depends on whether government adopts its advice and integrates findings into policy, planning and budgets.
- Terms of reference provided for up to two meetings in 2026, raising questions about whether this timetable allows sufficient depth of analysis for complex, evolving risks.
- Climate and nature risks are treated together because ecosystem degradation amplifies climate shocks and climate change accelerates biodiversity loss, creating compounding vulnerabilities.
How businesses should respond to evolving security priorities
Businesses do not need to wait for formal policy changes to begin addressing climate and nature risks. Several practical steps can improve resilience and reduce exposure. Firstly, conduct a comprehensive risk assessment that includes climate and nature-related threats. This should cover direct operational risks, supply chain vulnerabilities and exposure to geopolitical instability linked to environmental stress. Understanding where risks exist helps prioritise action and allocate resources effectively.
Secondly, engage with suppliers about their own resilience measures. Ask how they are managing climate and nature risks, whether they have contingency plans and what steps they are taking to reduce vulnerability. Suppliers that demonstrate strong risk management are more likely to maintain reliable operations under stress. Similarly, diversifying suppliers across different regions can reduce dependence on any single vulnerable area.
Thirdly, review infrastructure and operational systems for climate resilience. This includes assessing whether facilities are vulnerable to flooding, overheating or extreme weather. It also means considering whether energy and water systems can withstand disruption. Investing in resilience measures now can prevent costly failures later and may also improve efficiency and reduce operating costs.
Fourthly, integrate climate and nature risks into financial planning and reporting. This includes understanding how these risks could affect asset values, revenue, costs and access to capital. Transparent reporting on environmental risks and resilience measures can improve investor confidence and support long-term planning. Additionally, businesses that report comprehensively may find it easier to comply with future disclosure requirements.
Fifthly, stay informed about policy developments and government recommendations. The taskforce's findings will likely inform future regulations, procurement standards and infrastructure planning. Businesses that track these developments can anticipate changes and prepare accordingly. This includes participating in industry consultations, engaging with trade bodies and reviewing government publications on climate and resilience.
For businesses seeking support with carbon reporting, climate risk assessment or net zero program compliance, professional guidance can help navigate evolving expectations. Similarly, understanding how sustainable procurement practices align with government priorities can improve competitiveness in public sector tenders and strengthen supply chain resilience.
Finally, consider how climate and nature risks intersect with existing business priorities. For example, energy efficiency reduces costs and improves resilience to energy price volatility. Water management reduces operating costs and mitigates drought risk. Biodiversity protection can enhance brand reputation and reduce regulatory risk. Aligning environmental action with business strategy creates value beyond compliance and resilience.
