EFFC/DFI Climate Adaptation & Resilience Guide-PDF

Pdf Summary

The 2025 EFFC/DFI Sustainability Guide No. 3 provides practical guidance for geotechnical designers and contractors to adapt to climate change and strengthen resilience, supporting UN Sustainable Development Goals 11 (Sustainable Cities and Communities) and 13 (Climate Action). It complements earlier guides on carbon reduction and the circular economy.<br /><br />Climate hazards affecting geotechnical work include flooding, changing groundwater and sea levels, drought, soil shrinkage and swelling, erosion, landslides, extreme temperatures, wildfire, stronger winds and thawing permafrost. Hazards can occur together, creating cascading impacts on infrastructure, communities, ecosystems and business operations.<br /><br />The guide highlights growing physical and transition risks, including project delays, asset damage, worker safety concerns, disrupted supply chains, insurance and financial pressures, and changing regulations and client expectations. At the same time, demand for flood protection, resilient infrastructure and renewable-energy projects creates opportunities.<br /><br />For designers, the guide recommends assessing exposure, vulnerability and risk using future climate information; considering compound hazards and the asset’s service life; and comparing engineered, nature-based, adaptive and monitoring-based solutions. Designs should balance resilience, cost, carbon impacts and effects on surrounding communities. Instrumentation and long-term monitoring can track conditions, provide early warning and inform future decisions.<br /><br />Contractors are encouraged to embed resilience in business planning, challenge project assumptions and design choices, build flexibility into schedules and budgets, protect sites and maintenance yards, diversify suppliers, and prepare equipment and workers for extreme conditions. They should also retain accessible construction records to support future adaptation.<br /><br />Progress can be measured through project and company indicators, such as weather-related lost days, disruption costs, extreme-weather accident rates, climate-related revenue, carbon-tax exposure, and the share of equipment using hybrid or low-emission technologies. The guide is a practical reference, not a standard or regulation.
