Mercer’s advice on net-zero implementation




Driving debate and change at COP27 in November in Egypt


Institutional investors are under pressure to address climate loss, damage and transition. As trusted advisors to our clients, we have the ability to effect deep and global change. We know that many of our clients are committed to using their influence to accelerate the journey to net zero, in line with regulation, industry standards and beneficiary/members and stakeholder wishes.


At this year’s COP27, Mercer’s Rich Nuzum, Cara Williams, Helga Birgden hosted a panel discussion – “Harnessing the power of global capital to target local climate challenges” – alongside esteemed guests Rick Lacaille, Senior Advisor, StateStreet, and Gertraud Wollanksy, Senior Advisor on climate issues in the Austrian Ministry for Climate Action. They discussed client actions, opportunities and challenges to investing for net zero pathways. You can watch a recording here.

Helping you invest in a time of transition

Our extensive experience in portfolio modeling enables us to help our clients reshape their own investments to address ESG considerations over the short, medium and long term. We examine portfolios through the lens of important themes including population growth, resource scarcity and energy efficiency. This helps us identify companies, sectors, assets and projects that are expected to grow through new technology, along with those that may be put at risk due to these themes and the changes they bring.


Our transition framework helps investors establish their current emission baselines, while assessing how to make reductions, set target milestones and developing an implementation plan that can be integrated within decisions on strategy and portfolio construction.

Our commitment to net-zero by 2050

In line with our goal to place sustainability at the center of our investment approach, we have committed to target net-zero absolute carbon emissions by 2050 across the majority of our funds as part of our global investment roadmap. We expect to reduce absolute portfolio carbon emissions by 45% from 2019 baseline levels by 2030. Find out more in a short video by Mark McNulty, International Head of Clients, and read our press release.

Helping you model climate crisis scenarios                           


Mercer’s global partnership with Ortec Finance provides all types of institutional investor with rigorous analysis of the climate crisis. Our scenario modelling, from 1.5°C to 4°C warming, helps investors decide how they want to influence the climate crisis and provides the basis for making their portfolios robust to future challenges while exploring emerging opportunities.


Our quantitative analysis is grounded in economics and science and is in line with TCFD reporting. It provides a deep level of granularity, allowing clients to consider whether climate impacts are fully priced into every asset class and economic sector before making reallocation decisions. The long-term projections are integrated into Mercer’s capital market assumptions across all our services.
