Reflecting on 2025

As 2025 concludes, we extend our thanks to our sponsors, partners, and friends who supported Spotlight 2025. Held from 23 to 25 June, the summit focused on the theme "Flood-Resilient Cities: Adapting to Climate Change," addressing the growing threat of storms and floods to cities. Industry leaders shared strategies for flood resilience, showcasing how collaboration drives innovation toward climate resilience.

In this edition of our newsletter, we’re excited to share the highlights of 2025 and offer a preview of what’s ahead in 2026. Let’s take a moment to reflect on this year's milestones.

Season’s Greetings and a fantastic New Year to all!
