Our Carbon Footprint Climate change is a central topic in global ESG conversations. In 2022, we began our journey to understand how we, at a firm-level, can play a role in the fight against climate change. We completed our first firm-level carbon footprint using the GHG Protocol Corporate Accounting and Reporting standard.1 Recognizing the impact of 2020 travel restrictions during the COVID-19 pandemic, we chose to use 2019 as a baseline year. We are currently developing carbon reduction-related policies and strategies to reduce our footprint over time.
