International Coalition for Sustainable Infrastructure (ICSI)

What International Coalition for Sustainable Infrastructure (ICSI) does

International Coalition for Sustainable Infrastructure (ICSI) is a London-headquartered, UK-registered nonprofit coalition founded in 2019, with origins tracing to The Resilience Shift programme established in 2017 under Lloyd's Register Foundation and Arup. ICSI mobilizes an engineering-led coalition spanning engineers, policymakers, investors, academics, NGOs, and businesses to integrate climate resilience, sustainability, and nature-positive considerations into infrastructure decisions globally. Its portfolio consists of programs, campaigns, and publications rather than commercial software products: Resilience4Ports (a multi-stakeholder maritime resilience program with 30+ port authority members across five continents), the Engineering Leadership Group (hosting AECOM, Arup, GHD, Mott MacDonald, and Worley), three Action Tracks (Funding and Finance; Guidance, Tools and Standards; Energy Transition), the #EngineeringChange campaign for young engineers, the ISLe Learning Hub for engineering education transformation, and an annual Climate Resilient Infrastructure Report series together with foresight reviews such as the Nature-Positive Engineering Foresight Review and frameworks including the Port Resilience Framework for Action and the Port Decision Makers' Guide to Climate Risk Assessment.

ICSI is supported by a lean team of approximately 9 employees and funded through core funding partnerships with named institutional partners including Bentley Systems, Lloyd's Register Foundation, and the Global Covenant of Mayors for Climate and Energy; no membership fees, commercial pricing, or revenue figures are disclosed. The go-to-market relies on convening at major climate venues (COP27 through COP30, London Climate Action Week, Innovate4Cities), publication dissemination, LinkedIn newsletter distribution, and coalition participation rather than traditional sales motions. Distribution to port authorities and other stakeholders occurs through direct program registration for Resilience4Ports, Action Track volunteer participation, and coalition membership. Executive leadership comprises Executive Director Savina Carluccio and Board Member Tom Lewis, with no further management disclosures available.

The organization previously operated as Resilience Rising (and before that The Resilience Shift) before completing a rebrand to ICSI by 2026, and it has expanded formal alliances with bodies such as the European Council of Civil Engineers, the Coalition for Disaster Resilient Infrastructure, and the World Federation of Engineering Organizations. Revenue mechanics are non-commercial and grant/funding-based, customer concentration sits with a small number of core funders, and the underlying technology is a knowledge coalition and convening platform rather than a software or AI product.

Core offering

ICSI is a global, engineering-led non-profit coalition that develops and disseminates guidance, tools, frameworks, and publications to make resilience and sustainability a cornerstone of every infrastructure decision. It convenes engineers, policymakers, investors, academics, NGOs, and businesses through programs such as Resilience4Ports (maritime resilience), the Engineering Leadership Group, Action Tracks, and the #EngineeringChange campaign, supported by core funding from strategic partners.

Product overview

ICSI operates as a global coalition rather than a single unified software product. Its core offerings consist of programs, campaigns, publications, and initiatives focused on sustainable and resilient infrastructure. The main programs include Resilience4Ports (a multi-stakeholder whole-system approach for maritime sector resilience), the #EngineeringChange Campaign (providing learning pathways for young engineers), and the ISLe Learning Hub (transforming engineering education). ICSI also hosts the Engineering Leadership Group (ELG) which unites major engineering firms, and coordinates Action Tracks focused on funding/finance, guidance/tools/standards, and energy transition. Supporting these programs are publications including the Climate Resilient Infrastructure (CRI) Report Series, Infrastructure Pathways, and various guidance documents such as the Port Decision Makers' Guide to Climate Risk Assessment. ICSI functions primarily as a convening organization that mobilizes engineering expertise, develops guidance and frameworks, and facilitates knowledge sharing rather than as a technology product company.

Products and services

• Resilience4Ports (R4P) Program A multi-stakeholder whole-system program in the global maritime sector that seeks to enhance the resilience of ports and the communities that rely on them. It disseminates critical research, pilots priority solutions with partners, shares findings from pilot activities, and establishes a longer-term ports and cities network. Target audience: port authorities, maritime operators, and resilience practitioners.
• Nature-positive Engineering Foresight Review A foresight review exploring the emerging field of nature-positive engineering (NPE) through coastal protection and adaptation, ports, and offshore renewable energy. It identifies ten guiding principles and three pathways for scaling up NPE implementation. Target audience: engineering firms, policymakers, and infrastructure investors.
• #EngineeringChange Campaign A campaign designed to bridge the gap by providing tools, resources, and opportunities for young engineers to lead sustainable development initiatives and advocate for change within the engineering profession. It includes Learning Pathways featuring free online courses, manuals, standards, guidance documents, and real-world case studies. Target audience: young engineers (up to age 35) and engineering educators.
• ISLe Learning Hub (Transforming Engineering Education) A virtual learning series as part of the Infrastructure Sustainability Learning (ISLe) Initiative designed to accelerate knowledge sharing and collaboration across the global engineering community.
