Alex is Senior Vice President, Climate and Sustainability Consulting at Marsh Advisory based out of Tokyo. He supports large corporate clients across the APAC region by providing fit for purpose climate risk insights to help drive value adding risk management and mitigation strategies.
Alex joined Marsh from Commonwealth Bank of Australia (CBA) in Sydney, where he led the group climate analytics practice responsible for building out climate physical and transition risk maturity across the bank's mortgage, business and institutional banking divisions. Apart from working with business to develop climate risk management risk indicators and appetite statements, he was instrumental in crafting strategy around emerging risks such as the challenge of insurability of its mortgage book, and spearheaded the bank's climate scenario response to the inaugural APRA climate vulnerability assessment in 2022.
Prior to CBA, Alex was Head Nat Cat and Sustainability (APAC) at Swiss Re (a large international reinsurer) based out of Tokyo and Singapore, where he managed the underwriting of its property portfolio, and developed bespoke climate risk solutions and innovative parametric insurance solutions. Alex has been recognized as a thought leader within industry through the Risk Leader of the Year award by Risk Management Institute of Australia (RMIA) (2022). He continues to remain active in research as Adjunct Fellow at the Climate Change Research Center (CCRC) at the University of New South Wales. His recent research interests include economic impacts of climate change, climate scenarios, and behavioural biases/ attitudes towards catastrophe tail risk.
