Sustainable Growth

We are committed to serving as a force for progress in combating climate change and acknowledge that climate adaptation is critical to the success of our business and our policyholders. Being values-driven means proactively adopting climate strategies that stem from Liberty Mutual’s purpose — to help people embrace today and confidently pursue tomorrow — and proactively supporting the responsible transition to a low-carbon economy.

Integrating Sustainability into Business & Investments 

Part of Liberty Mutual’s commitment to sustainable growth includes integrating sustainability into our core business and investment decisions. It will be a multi-year journey, requiring a proactive and thoughtful approach to balancing the different needs of our customers and risks across geographies, while building on evolving research and technology. We’re committed to supporting other companies at varying points in their sustainability journeys with products, services and solutions that can help.

Addressing Climate Change

Liberty Mutual is advancing climate resiliency and supporting a global energy transition, while putting people first — our customers and policyholders, employees, investors and communities. We are thoughtfully transitioning our business while protecting and supporting the interests of our policyholders and capital providers.

In 2023, we continued to reduce our operational carbon footprint and expand our sustainability efforts, while office occupancy and business travel increased. To reduce our operational emissions, we leverage efficiencies and a data-driven approach to real estate portfolios, fleet usage and business travel.

Building operations

We are making our buildings more efficient by focusing on reducing energy consumption and optimizing operations. Our Boston headquarters was awarded the First Place 2024 American Society of Heating, Refrigerating and Air-Conditioning Engineers Technology Award in recognition of outstanding achievement in the design and operation of energy efficient buildings. The campus also won the 2023 Massachusetts Save Climate Leader Award for efforts to increase energy efficiency and reduce emissions. Additionally: 

  • In the U.S., three of our owned buildings have LEED certifications and two have Energy Star certifications. 

  • Our Plano, Texas building has reduced its energy consumption by 8% by installing an energy-efficient cooling system and making continuous energy efficiency improvement. It also sources a majority of its electricity from renewable power generation.

  • In Singapore, our team conducted a detailed workplace scenario analysis to optimize and reduce space. As a result, we shifted from a six-story building to a single floorplan.  

  • Our Asia Pacific region selects high-efficiency buildings for its operations that have a National Australian Built Environment Ratings System (NABERS) rating for sustainability performance.  

  • In China, we lowered emissions significantly by reducing our office space footprint while simultaneously redesigning the spaces to enhance the employee experience. 

  • Our London office is BREEAM-certified complete with life cycle assessment and green energy supply.

We are taking action to lessen our environmental footprint by reducing the waste generated across our operations. Specific actions include:
