The International Coalition for Sustainable Infrastructure identifies and addresses the biggest barriers to action that have prevented us from working together for a sustainable, resilient and inclusive future. While the engineering-inclusive organizations at the center of the coalition seek to bring the kind of practical, science-based and solutions-oriented perspective that engineers are generally known for, we recognize that engineering-inclusive organizations alone cannot solve the systemic problems that exist at the intersection of climate change, aging infrastructure, and underinvestment. A multidisciplinary, multi-sector, global coalition is needed to break down the silos that have contributed to our collective failure to adapt and mitigate.
