Climate Change Drives Urgent Need for Resilient Infrastructure

UK's rail network faces £3 billion cost from climate-related disruptions over 15 years, with 1,548 million minutes of delays in 2023-24. Network Rail invests £2.8 billion to bolster resilience, while global efforts focus on climate change mitigation and adaptation.

Climate Change Drives Urgent Need for Resilient Infrastructure

As the frequency and severity of extreme weather events continue to rise, the need for a proactive approach toincreasing community resiliencehas become increasingly urgent. Climate change is driving this necessity, with the UK's rail network facing mounting disruptions that have incurred a staggering £3 billion cost to network operators over the past 15 years.

Why this matters: The impact of climate change on infrastructure resilience has far-reaching consequences for global economies, food security, and human lives. Failure to adapt and invest in resilient infrastructure could lead to catastrophic losses, displacement of communities, and a significant setback to sustainable development goals.

The latest reporting year of 2023-24 saw a total of 1,548 million minutes of delays across the network, equivalent to a staggering 1,075 days. Emissions from trains alone amounted to 2.2 million tonnes of CO2 equivalent between April 2022 and March 2023. Thom Rawson, Sustainable Rail Principal at the Rail Safety and Standards Board (RSSB), emphasizes the gravity of the situation, stating, "Year after year, we see the increasing impact of extreme weather events like storms, floods, and heatwaves hurting our rail network and the communities it serves."

In response to these challenges, Network Rail has announced a £2.8 billion investment over the next five years for initiatives and technological upgrades aimed at bolstering resilience to extreme weather conditions. The RSSB has launched its Sustainable Rail Blueprint, a framework to guide the rail industry towards decarbonisation and climate resiliency. Arup has also released its Rail Resilience Framework, warning that industry action must include collaboration between all sections of rail operation, governments, businesses, and local communities.

The urgency of addressing climate change extends far beyond the rail industry. Bikash Prasad, President & CFO of Olam Agri, highlights the global scale of the crisis, noting that atmospheric CO2 levels have risen by over 40% since industrialization began 70-80 years ago. The impacts are being felt worldwide, with India experiencing 50% lower crop yields due to heat waves and Pakistan suffering losses of up to 25% of its GDP fromfloods.

According to the World Economic Forum's annual Global Risks Perception Survey, climate change and environmental threats have become the top five highest impact risks globally. The top 10 emitters account for 64% of global greenhouse gas emissions, with China alone emitting 30% at 16 gigatons. Prasad emphasizes the need for urgent collective action across nations, companies, and individuals to curb emissions and limit global warming.

Cities across Europe are taking proactive measures to enhance their infrastructure resilience and adapt to the impacts of climate change. The European Environment Agency's Urban Adaptation in Europe report showcases diverse actions undertaken by European cities to address climate risks, emphasizing the effectiveness of strategies such as urban planning, early warning systems, and nature-based solutions. The report serves as a call to action for a climate-resilient Europe, highlighting the imperative for proactive measures to ensure resilience in the face of climate change.

The world has already witnessed severe climate events in 2024, including a deadly heatwave in the Sahel, drought in Zimbabwe, and catastrophic storms in the U.S. Many of these global events are attributed to El Niño, a climate pattern that warms the surface of the oceans in the eastern equatorial region, impacting global weather and trade winds. The Sahel region in Africa, with a population of over 100 million people, is a hotspot for conflict due to climate change, facing dire living conditions and famine.

Innovations in climate tech play a crucial role in adapting to and mitigating the impacts of extreme weather. Enhanced weather prediction models, new building materials and designs, and efficient water management technologies contribute to the development of resilient infrastructure that can withstand the challenges posed by climate change. As David Wallace Wells of the New York Times warns,"The world may be entering a much bloodier era as a result [of climate change]."

In New York City, the Metropolitan Transportation Authority (MTA) has unveiled its Climate Resilience Roadmap, a comprehensive framework to protect the transit system from the impacts of climate change. The roadmap includes strategies such as defending the subway system from flooding, reducing coastal and rainfall flooding on railroads, and protecting infrastructure from extreme heat. The estimated capital costs for implementing these measures are up to $6 billion over the next decade.
