Building Certifications

Kilroy pursues globally recognized green building certifications to identify and demonstrate achievement of research-backed building design and operational strategies that enhance building efficiency and the wellness of tenants and residents. Green Buildings offer building users healthier environments, while also lowering global carbon emissions and reducing electricity and water bills.

Carbon Neutral Operations

Driving environmental progress through design and operations.

Our sustainability efforts are broad, and include a focus on energy, carbon, water, waste, health & wellness, and stakeholder engagement.  We identify climate change as both a risk and an opportunity to our business and we build these factors into our strategy and risk management efforts.  Our sustainability programs contribute to long-term value creation and help shape our corporate strategy.

We are proud to have achieved carbon neutral operations across our portfolio since 2020.  This means that all greenhouse gas emissions associated with the operation of our buildings—specifically electricity and natural gas usage—have been measured and then reduced or offset to achieve a net-zero carbon footprint. Our carbon neutral operations strategy covers all Scope 1, 2, and 3 (downstream leased assets) emissions and involves the following strategies: onsite energy efficiency, onsite renewable energy generation, offsite renewable energy purchasing, renewable energy certificates (RECs), and verified carbon offsets.
