Lotus is a women-owned, data driven and client-centered boutique engineering and sustainability consulting firm. We are endlessly curious professionals who have more than a decade of experience in the environmental and sustainability fields. We bring expertise and creative thinking to engage with clients and draw on our experience in market and regulatory / policy creation and analysis; financial acumen; communications and project and program management.

Lotus is a certified Women-Owned business (M/WBE), Emerging Business Enterprise (EBE), and Small Business Enterprise (SBE).


Since 2012, Lotus has delivered responsible and progressive sustainability solutions for public and private sector clients throughout Colorado and the Midwest. Our consulting services combine the technical and pragmatic approaches of engineering and finance with the holistic and innovative approaches of efficiency and sustainability.


We make sustainability easier and more transparent by listening to and understanding our clients’ needs and providing data, tools and analysis to help them make informed decisions. We have supported public and private sector clients with their sustainability initiatives, energy performance contracting projects, solar gardens, greenhouse gas accounting, energy and water efficiency strategies, and market and regulatory analyses. We excel at helping clients look at their environmental and social initiatives through various lenses, including public relations, financial, political and environmental.


We provide data and resources to help communities make informed decisions that move the needle. By looking at project opportunities with an unbiased perspective, we can deliver objective information and tools that help cities make engineering and sustainability decisions based on both environmental and financial data.


Combining realism with a desire to do good things for the planet, while remaining neutral and, instead of telling clients what to do, we provide them with data and information and tools to make their own informed decisions. We do this because we are endlessly passionate about the engineering and sustainability field. We want to make the world a better place. We want to help secure a future for our children and our children’s children that is vibrant, healthy and safe.

"The team at Lotus Sustainability consistently produces professional assessments and reports that have greatly assisted our team and the local governments we work with. Emily and Hillary bring an unparalleled level of enthusiasm and expertise to each project. They provide timely proposals and have delivered their work earlier than promised each and every time. I would highly recommend the Lotus team to any entity that is working on carbon inventories, developing climate action plans, reviewing solar proposals and contracts, improving the efficiency of their own building or facility, and any of the other services they can provide."

-Erica Sparhawk, Director of Programs and Services, Clean Energy Economy for the Region (CLEER)

Who We Are

Emily Artale

Emily Artale

Hillary Dobos

Emily Artale; PE, CEM, LEED AP

Principal Engineer and Co-owner

Emily has been an environmental and sustainability consultant for over a decade. Her education and work experience began in water quality and evolved to energy and sustainability. She started Lotus in 2012 because she saw gap in many of the environmental and sustainability related services being offered. There were big-picture global thinkers that were dedicated to making our world a better place and there were detail-oriented, pragmatic engineers that were cautious of major changes. Few offered big-picture and progressive solutions that considered fundamental, real-life constraints. She created a company that addressed these issues, resulting in transparent, defensible, and world-changing solutions. She asked Hillary to join her shortly thereafter to bring redundant skill sets to the company and to take advantage of Hillary's expertise in business, finance, and policy. 

Emily has worked with private companies developing greenhouse gas emission inventories, integrating sustainable practices into corporate operations, and tracking performance metrics. She has helped public agencies develop, manage, and execute energy efficiency programs, navigate through energy performance contracting projects, assess risk scenarios for engaging in renewable energy systems, and develop climate action plans. As part of a UN sponsored initiative, she worked with world renown sustainability expert, Hunter Lovins, on redefining manufacturing using sustainable practices.

She received her undergraduate and graduate degrees in environmental engineering from the University of Colorado at Boulder. She is a Colorado native and spends most of her time outdoors with her family.
