17 February 2021 – The ClimateWise Principles Independent Review for 2020 has seen record improvement in scores across the ClimateWise membership.

Climate Wise Principles 202Download the ClimateWise Principles Independent Review 


The ClimateWise Principles Independent Review 2020 shows member insurance industry firms have made significant progress in disclosing their preparedness and response to climate change.

The Review records a significant increase in average score - from 55 per cent in 2019 to 65 per cent in 2020 - for the ClimateWise group of organisations. The increase in group scores in 2020 has been predominantly driven by members demonstrating significant progress in the incorporation of climate change considerations into investment and underwriting strategies, high participation by members in climate stress tests and improvements made in the integration of climate risk into existing risk management frameworks.

There remains scope for improvement and there is still a need for urgent action across the industry. The main focus for members this year will be on deepening the exploration and transparency of strategic resilience to climate change. This will most notably be through expanded adoption and depth of scenario analysis, demonstrating the outcomes and implications on resilience and the resultant impact on decision-making.


The ClimateWise Principles have provided a framework for the insurance industry to disclose climate-related risk and opportunity since 2007. All ClimateWise members report annually against this framework. Reports are independently reviewed, scored and anonymised in a combined report to form the ClimateWise Principles Independent Review.

Aligned with the Taskforce on Climate-related Financial Disclosures (TCFD) recommendations in 2019, this review marks the second year of TCFD compliant reporting. The results are encouraging, indicating ClimateWise members will be well prepared for forthcoming mandatory TCFD reporting.
