UK Climate Change Risk Assessment 2022

The "UK Climate Change Risk Assessment 2022" (CCRA3) report outlines the climate change risks facing the UK and presents a comprehensive analysis of the potential impacts and necessary adaptation strategies. It is part of a statutory requirement under the Climate Change Act 2008 to assess climate risks every five years. This third assessment identifies 61 climate risks and emphasises the need for urgent action in many areas to mitigate these risks effectively. The report includes:

1. Executive Summary: Highlights the current climate challenges, the anticipated increase in temperature, and the importance of both mitigation and adaptation.
2. Legislative Framework: Details the legal obligations and responsibilities of the UK and devolved administrations in addressing climate change.
3. Technical Report: Provides a detailed analysis of risks across various sectors, including the natural environment, infrastructure, health, and the economy.
4. Advice Report: Summarises key findings and prioritises eight risk areas requiring immediate action.
5. National Summaries: Discuss specific risks and opportunities for England, Northern Ireland, Scotland, and Wales.
6. Sector Briefings: Offer tailored information for different sectors to guide their adaptation efforts.

In terms of Transport and Infrastructure, the assessment identifies the following:

Key Risks and Impacts:

• Infrastructure Networks: Increased risk of cascading failures across water, energy, transport, and ICT networks due to climate hazards like flooding and heatwaves.
• Transport: Climate-related disruptions to transport infrastructure, including damage to roads, railways, and airports from extreme weather events.
• Supply Chains: Vulnerability of supply chains and distribution networks to climate-related disruptions, affecting the availability of goods and services.

Priority Actions:

• Adaptation Investments: Emphasises the importance of early adaptation investments in infrastructure to ensure resilience against future climate impacts. These investments are seen as cost-effective with high benefit-cost ratios.
• Policy Integration: Calls for mainstreaming adaptation into all government policies and decision-making processes, particularly in sectors with long-term impacts like infrastructure development.
• Collaboration: Encourages cooperation between different levels of government and sectors to implement cohesive adaptation strategies and avoid maladaptation.
