Collins is an active participant in the Global Adaptation and Resilient Investment (GARI) working group, which was launched at the Paris COP21 global climate talks in 2015 and is now an official partner of the United Nation’s Secretary General's A2R Climate Resilience Initiative.
GARI has convened over 150 private investors, climate experts and other stakeholders in New York, London, and Washington DC to discuss practical approaches to investing that consider climate adaptation and resiliency.
In 2017 the GARI group focused on developing an investor guide in response to interest from the private sector and private investors in climate adaptation and resilience.
The GARI 2017 Investor Guide to Physical Climate Risk and Resilience provides a 5-page "plain language" introduction to physical climate risk and resilience for investors. An initial draft was posted during the United Nations COP23 global climate talks in Bonn. The final Investor Guide was released during the One Planet Summit in Paris in December 2017.
Lead authors are: Jay Koh, Founder of the Lightsmith Group; Emilie Mazzacurati, Founder of Four Twenty Seven, Inc.; and Chiara Trabacchi, PhD at IDB Invest. Collins is a contributing author to the guide.
