Project Spotlight
The Business Case for Responsible Corporate Adaptation
Four Twenty Seven was the lead author on the latest Caring for Climate report on The Business Case for Responsible Corporate Adaptation, developed in cooperation with the UN Global Compact, UNFCC, UNEP, and their partners.
The report explores the strategies, actions and partnerships through which businesses adapt to climate impacts while creating shared resilience benefits for the communities and ecosystems where they operate.
