Kari Klaus' Bio

Bringing Sustainability to the Real Estate Industry

Kari Klaus, the founder of Realty Sage, is a trailblazer in the world of sustainable real estate. Her passion for sustainability and her entrepreneurial spirit have led her to create Realty Sage (formerly Viva Green Homes) that connects people with sustainable homes and real estate professionals.

Klaus's journey to becoming a sustainable real estate pioneer began with her own personal journey towards living a more eco-friendly lifestyle and home. As she began to research the environmental impacts of real estate and its contribution to climate change, she found a tremendous gap of information about the benefits and value of eco-friendly homes in real estate. This led her to create Realty Sage and the proprietary Sage Score and Livability Categories which are the most comprehensive, automated, apples-to-apples scoring available for eco-friendly homes.  

Through her work with Realty Sage, Klaus has become a recognized expert in sustainable real estate. She has spoken at conferences and events around the world and has been featured in numerous publications. Her efforts have also been recognized through awards and honors. 

Klaus's commitment to sustainability extends beyond her work with Realty Sage. Her travels in Asia, and having lived in Europe and Mexico, have given her a unique perspective on the global impact of sustainability, and she continues to use her platform to raise awareness and promote positive change. She is also involved in various environmental organizations and is an advocate for sustainable living and communities.

Klaus champions a brighter, eco-friendly, and more inclusive future for living in our homes by making sustainable homes easier to understand and adopt, while aspiring for a greener planet in her community and beyond.
