Moving Capital at Scale for Climate and Care
Tuesday, September 22, 2026
While every Climate Week is filled with commitments, far less capital actually moves. This time, Human Planet is spurring the conversations that help to close the gap. Join Human Planet for our Moving Capital for Climate, Care and Children event, and hear about innovative, blended solutions that actually work. Speak to the people who allocate capital and the ventures ready to receive it. The room is small by design and the guest list is strictly limited, allowing for more than small talk in a calm, pragmatic way.

Flagship One: The challenge – navigating a world in flux
Monday, September 21, 2026
Across the world, leaders are navigating a rapidly shifting landscape. 2026 saw the worst energy crisis of our time, driving up the cost of living and placing real strain on households, businesses and public finances. At the same time, disrupted supply chains are pushing up costs and slowing down delivery, while climate impacts, from extreme heat to flooding, are exacerbating the pressure and exposing age-old vulnerabilities. The challenges are interconnected, reinforcing one another and making progress harder to sustain. The challenge isn’t setting ambition, but delivering in a world where economic, climate and geopolitical pressures are deeply intertwined. In this moment of crisis and opportunity, what do we need to do to implement change at pace and scale?

Interior Ecologies
Tuesday, September 22, 2026
Interior Ecologies is a critical framework developed within the Master of Arts in Interior Architecture (MAIA) program at Geneva School of Art and Design (HEAD – Genève). It examines how interior architecture engages with climate change, resource circulation and multispecies coexistence alongside posthuman and more-than-human design perspectives. Rather than treating interiors as autonomous spaces, it calls on us to rethink them as complex ecologies in which human and nonhuman actors are entangled across broader planetary scales.
This roundtable brings together voices from HEAD – Genève, MoMA, and Columbia GSAPP to reflect on how interior architecture can contribute to new ecological approaches to design, research, and professional practice.

Harnessing collaborative action to accelerate energy efficiency
Monday, September 21, 2026
Across sectors and geographies, companies are already investing in energy efficiency, electrification, cooling, flexibility and decarbonization, even as political uncertainty and competing economic priorities test the pace of climate action. Individual companies are taking action. The opportunity is how those individual actions can be harnessed into a collective force that gives governments, investors and markets the confidence to move faster. Run in partnership with CLASP, RMI and Climate Group, this session will explore how collaborative action between business, civil society, philanthropy and policy leaders can be harnessed to accelerate climate and energy efficiency progress at scale.
