At Green Room, we believe in reshaping luxury living by embracing sustainability. We envision a future where carbon neutrality isn’t a distant goal, but an integral aspect of property management. We make carbon neutrality achievable to every property, regardless of its size or location.

Residential and commercial buildings produce about 25% of California’s greenhouse gas (GHG) emissions when accounting for electricity demand and fossil fuels consumed onsite.

Green Room was founded on the belief that every organization has a role to play in combating climate change. Recognizing that buildings account for a significant portion of global greenhouse gas emissions, we saw an opportunity to make a meaningful difference. Leveraging secure data connections to utility providers, we've built a system that calculates the carbon footprint of buildings accurately and efficiently, providing property managers with a clear path to carbon neutrality.

Our mission is to transform the conversation around carbon neutrality from a question of 'Can we afford to?' to 'Can we afford not to?'

Our Commitment.

We're committed to transparency, accuracy, and accountability in everything we do. Our carbon footprint calculations are guided by the Greenhouse Gas Protocol, the world's most widely used greenhouse gas accounting standards. Verification is performed by The Climate Registry, an internationally recognized non-profit that ensures our work meets the highest standards of environmental integrity. All our carbon offsets are sourced from projects verified by ClimatePartner according to standards such as the Gold Standard and Verified Carbon Standard, ensuring your investment has real, measurable impact.

Whether you're a property manager ready to make your buildings carbon neutral, or you're just interested in learning more about our work, we'd love to hear from you. Join us in our mission to make carbon neutrality the norm, not the exception. Together, we can create a healthier, more sustainable future for our planet.
