This year’s report reaffirms Kilroy’s longstanding position as a sustainability leader in the commercial real estate sector. With operations spanning San Diego, Los Angeles, the San Francisco Bay Area, Seattle, and Austin, Kilroy continues to prioritize sustainability as a strategic driver of value, resilience, and innovation across its portfolio.
Setting the Course: 2030 Sustainability Goals
In a clear demonstration of its continued commitment to responsible development and operations, Kilroy’s new 2030 Sustainability Goals cover a broad spectrum of environmental and social priorities.

These targets aim to reinforce Kilroy’s leadership in climate responsibility while ensuring meaningful progress in areas such as health, wellness, equity, and diversity.
Kilroy’s leadership views these goals not just as benchmarks but as part of a larger corporate mission. “Over the past year, we have taken meaningful strides to more deeply embed sustainability into our strategy and operations,” stated Angela Aman, Kilroy’s Chief Executive Officer. “Successful execution of sustainability efforts requires innovation, leadership, and most importantly, collaboration between colleagues across the entire organization.
