In context

Addressing climate change is a responsibility we all share – as individuals and as organisations. This is the ‘Climate Decade’ where we must act decisively, boldly and together.

This is the ‘Climate Decade’ where we must act decisively, boldly and together.

There is tremendous and growing risk in the destruction brought about by climate change, but also great opportunity in the transition possible to a greener and fairer world.

We firmly believe that sustainable investment is central to successful long-term investor outcomes. In particular, climate change, and a just transition to net zero carbon emissions, is a systemic and urgent global challenge which necessitates specific risk management, opportunity identification and collective action.

We have identified climate change as a critical and systemic priority, given the risks it presents to our clients’ investments, the ongoing resilience of the savings universe, and the planet as a whole.

Our approach combines deep research, proprietary portfolio management tools and analysis, effective stewardship and industry collaboration. We look to deliver this via practical solutions tailored to individual client contexts. This forms part of Willis Towers Watson Climate Quantified™, supporting corporate, finance and public sector clients to identify, assess and act upon physical, transition and liability risks arising from regulatory, investor, consumer, employee and operating pressures.

Compelling climate investments

Improving investment outcomes – better return and lower risk continues to be the mainstay in every decision we make. The following examples are compelling investments in its own right, supported by long-term sustainability trends, but as a set these investments benefit further from having attractive environmental impacts.

We have made as part of our secure income and multi-asset pooled fund solutions. Some of these investments were also made by our segregated delegated accounts, and indeed in some cases also by our advisory clients.
