A Message From Our CEO

I am proud to present to you Aon’s 2021 ESG Impact Report.

It was a year in which we faced new and ongoing obstacles, made progress on critical challenges and achieved hard earned successes.

Our firm exists to shape decisions for the better — to protect and enrich the lives of people around the world. Aon’s aim is to help businesses thrive while ensuring the communities they serve and the people they employ flourish. In our highly volatile, fast-paced world, we look to provide the world’s decision makers with the clarity and confidence to make better decisions.

The impacts of the COVID-19 pandemic have fundamentally disrupted the way we work, live and conduct business. Now, more than ever, resilience and growth are dependent on business leaders taking action to respond to environmental, social and governance (ESG) risks and opportunities. ESG-related challenges such as extreme weather events, supply chain disruptions and public health crises continue to bring great volatility and uncertainty to our world. We are at a pivotal moment as a firm, but more importantly as a society. It is why throughout 2021, we continued to advance our ESG strategy, capabilities and solutions to enable better decisions that help build a better world.

Aon’s values are at the heart of our ability to drive impact around the world. They define who we are as a firm and drive the very behaviors that help Aon shape decisions for the better.

Together, we are:

  • Committed as one firm to our purpose
  • United through trust as one inclusive, diverse team
  • Passionate about making our colleagues and clients successful

The Aon Story

By working together as one firm and enabling our colleagues to bring the best of Aon to address client needs — delivering our Aon United approach — we’ve brought together the breadth and depth of our global firm’s expertise, insights, technology and data and analytics to strengthen our ESG strategy and offerings, enabling our firm and our clients to create more sustainable value.

Together, we’ve focused on enhancing our operations and delivering market-leading solutions to meet today’s challenges — including an ESG risk-assessment tool to help clients chart their ESG journey and monitor and respond to risks in real time.

Aon Business Services (ABS) has enabled us to further align our business initiatives to our ESG goals. The efficiencies we are now able to create across the firm through digitization and automation accelerate distribution of new solutions globally, improves the client experience, and reduces our overall carbon footprint.

Our ESG initiatives demonstrate our commitment to our various stakeholders and the communities in which we live and work:


We are leading a broad commercial and societal push to decarbonize the economy and to improve resiliency in the changing climate. This means helping our clients prepare for and respond to the challenges posed by the impacts of climate change, committing our firm to be carbon neutral by 2030 and collaborating with the public and private sectors to ensure we are building resilience together.


We are supporting initiatives that create greater equity and inclusion in business and society, starting with our culture and talent strategy. We believe our colleagues and culture power the Aon United strategy and we continue to strive to strengthen and empower our inclusive, diverse team. Our social commitments align with our business commitments and are embedded in our culture, work with clients, business practices, community involvement and philanthropic efforts.


Strong governance is at the core of what we do as a firm. Our own model is built for transparency and trust, helping us bring our purpose to life and create value for our clients and colleagues. In our client work, we help businesses navigate change in real time and create the structures, processes and models that lead to better decisions and accountability throughout the organization.

Despite the tremendous challenges we faced as a firm and a society in 2021, and we will continue to face in 2022 and beyond, we remain quite optimistic about the future. The evolution our firm is going through is nothing short of transformational and the efforts and outcomes delivered by our colleagues is nothing short of inspiring. This report, which details our ESG priorities and efforts, is a direct reflection of our belief that united, as a firm and as a society, there is nothing we cannot accomplish.

Thank you,

Greg Case
CEO, Aon plc
