“Position for transition. How are you going to act?” By Jillian Reid and Niall O’Sullivan, Mercer

Investors are increasingly considering climate change along with issues related to ESG and diversity, equity and inclusion (DE&I). Motivated by the economic and social interest of their beneficiaries and clients, investors now have the opportunity to use their portfolios and their influence to help guide us towards a low-carbon economy. There is more to this than just simply excluding companies from certain industry sectors. In terms of climate change and the transition to a low-carbon economy for example, we believe it’s important to consider which companies are adapting to this change and those that are not.

Our commitment to net-zero by 2050

In line with our goal to place sustainability at the centre of our investment approach, we are committing to a target of net-zero absolute carbon emissions by 2050 across the majority of our funds2 as part of our global investment roadmap. We expect to reduce absolute portfolio carbon emissions by 45% from 2019 baseline levels by 20303.

How we’re helping clients invest sustainably

Helping clients invest in a time of transition


We have undertaken extensive portfolio modeling and work with clients to reshape their portfolios to address ESG considerations. For example we look at investments associated with themes such as population growth, resource scarcity and energy efficiency that will provide access to companies, assets and projects that are expected to grow by enhancing technology.


Our transition framework helps investors set current emission baselines, assess their portfolio opportunities for emissions reductions, set targets for reductions milestones and develop an implementation plan that can be integrated within strategy and portfolio construction decisions.


Top accolade by the PRI


We were one of the first consultants to pioneer sustainable investment and have worked both with the PRI and other international organisations to promote best practice around the world for almost two decades. As a founding signatory to the PRI in 2006, we also helped shape its original statements and aims. In 2020, we were awarded an A+ and six As from the PRI for our $306bn of AUM in investment solutions across public and private markets.
