Aon's ESG
Impact Report

A Message from our Head of ESG

Thank you for reading Aon’s 2022 ESG Impact Report. This ESG report is about what we do as a firm and what we do for clients. I’m delighted to share the progress we’ve made against our long-term commitments and our strategy. These commitments are fully consistent and deeply embedded in Aon’s overall strategy and require the help and support of our full firm to deliver — just as we saw throughout the year. This year, we continued to drive progress on our ESG strategy, as we moved forward with our core commitments and advanced new initiatives to support long-term goals:

Environmental

We are committed to achieving net-zero carbon emissions by 2030. In 2022, our emissions were 453,520 tons of CO2 equivalent (CO2e), a reduction of 4% from 2021 and 16% from our starting 2019 baseline.* We continue to reduce our total footprint through key drivers of travel, commute, real estate, investments and our supply chain. Many of these reductions are made possible by Aon Business Services and our flexible Smart Working strategy, and we’ve found that these efficiencies not only reduce our carbon footprint but also improve employee wellbeing and client service.

Social

Our colleagues are at the heart of everything we do, and our Aon United strategy is designed to attract, retain, develop, reward, and support our people. Inclusion and diversity (I&D) remain an essential part of our culture, and we continue to take steps to embed I&D principles and practices throughout our organization. We hold ourselves accountable to this commitment with a dedicated I&D sub-committee of the Board, increased transparency on our human-capital management strategy and outcomes, and the inclusion of our I&D goals within our executive compensation structure. We aim to reflect our values and social commitments in our work with clients, business practices, community involvement and philanthropic efforts.

Governance

We remain committed to the highest ethical and compliance standards and design our governance structures to inform business decisions and improve the way we serve our clients efficiently and effectively. Aon’s colleagues and leadership continue to work across the firm, with partnership from management-led risk and product governance committees, to inform decision-making processes and build better decisions for our firm and clients. This year, we conducted a firmwide ESG risk assessment, in alignment with our overall enterprise risk management process. In addition, our Board of Directors reviewed ESG and climate risks, as part of their oversight of risk management. This oversight includes ongoing review of cyber security, data security and data privacy matters, an area in which we added new director expertise in 2022.

We made significant progress in 2022 and we look forward to continuing to build on this progress in 2023 – as we raise the bar on our impact for clients, colleagues and all stakeholders.

Thank you,

Leslie Follmer
Head of ESG and Investor Relations, Aon plc
