In June, City of Miami Mayor Eileen Higgins attended London Climate Week 2026, joining Mayor Kate Gallego of Phoenix and Mayor Barbara Buffaloe of Columbia, Missouri, as one of only three American mayors invited by Climate Mayors and C40 Cities to participate in the global convening. London Climate Action Week is one of the world’s leading gatherings focused on climate solutions, bringing together mayors, government leaders, business executives, climate experts, and international partners to accelerate action on resilience, clean energy, public health, sustainable infrastructure, and economic opportunity. 

Mayor Higgins had the opportunity to represent Miami on the panel Powering Progress: Climate Leadership in an Age of AI, and participated in discussions at Innovation Forum 2026, Future Health 2026, the C40 Mayoral Masterclass, and the America Is All In Business Roundtable where she highlighted Miami’s experience as a coastal city working towards a more resilient future by strengthening neighborhoods and modernizing infrastructure. She spoke about how Miami is financing projects to alleviate flooding and extreme heat through expanding green infrastructure, pump stations, cooling centers, permeable pavements, living seawalls, and tree canopy. Additionally she shared how Miami is reducing food waste through a residential compost drop-off pilot, and eliminating plastics in city concessions.

Her participation provided an opportunity to showcase leading resilience solutions being advanced in south Florida and share lessons learned from years of work on the front lines of climate change, while also learning from and bringing back novel ideas from other cities confronting similar challenges.
