With the financial community's growing interest in adaptation and resilience, so too have the attempts to narrow down and systematise adaptation into clear categories flourished. The rationale is clear – regulators need clear guidelines on what constitutes adaptation for effective regulation and investors want clear guidelines on whether an investment is adaptation-aligned. The burgeoning number of adaptation taxonomies launched by public and private actors in the past few years is testament to this. Yet, the ever-growing number of adaptation taxonomies and their pluralistic scopes and levels of detail risk jeopardising much-needed clarity on what constitutes adaptation.

The Resilient Planet Finance Lab is the first to compile and systematise a list of adaptation taxonomies. The inventory covers 35+ jurisdictional and non-jurisdictional taxonomies that seek to identify adaptation investments. The inventory, together with a forthcoming analysis, enables the financial sector to identify adaptation-aligned investment opportunities and craft comprehensive adaptation strategies.

The (In)coherence of Adaptation Taxonomies

Roberto Spacey Martin, Dr Nicola Ranger, Kit England

June 2024

Adaptation taxonomies are a key tool in the sustainable finance toolkit, creating clarity and coherence around what constitutes an adaptation-aligned investment. Twenty-four adaptation taxonomies have been published in the last 4 years, forcing us to ask the question: clarity or chaos? We compare these taxonomies based on their underlying principles, definitions of adaptation and sector coverage, and reveal major differences.
