Our Approach

We are an award-winning environmental consulting firm that designs sustainability into the DNA of organizations. With over a decade of experience working on sustainability initiatives across all seven continents, we help corporations, government agencies, special events, and communities navigate the “green noise” and implement systems to actively reduce their environmental impact. As a global leader in sustainability strategy and the first firm in the U.S. to achieve ISO 20121 certification, we enjoy working with a robust roster of clients at the forefront of the climate action movement, including Nike, ESPN, Honda, the United Nations Foundation, Disney, Universal Music Group, United Airlines, and more.

Our Mission

Working to protect and sustain the planet for generations to come.

Three Squares Inc. launched in 2008 with the mission to catalyze solutions that protect and sustain the planet for generations to come. The company was named after the pursuit of the triple bottom line – a business framework that focuses on aligning the three pillars of social, environmental, and economic.

Simple in concept, complex in execution. Strategies that balance these three pillars require a depth of commitment and rigor in analysis that are not easily achieved. Yet, the climate crisis has brought us to a critical inflection point. World leaders realize the consequences of using up more resources than we generate. Industry leads the net zero charge and clean tech innovation is at an all-time high. Financial markets recalibrate to screen investments through an ESG lens. Consumers call for product transparency and use their spend to vote for their values.

We are energized by the focus on climate action and by the privilege to work with those companies and organizations leading the charge. In many cases, we are our clients’ most trusted advisor. This allows us to drive strategy from the boardroom to the factory floor. We do not take this responsibility lightly and we will always commit to achieve excellence across the triple bottom line.

CINTA

The Three Squares Inc. (TSI) team adopted Cinta through the Borneo Orangutan Survival Foundation, an Indonesian non-profit dedicated to the conservation of the Bornean orangutan and its habitat.

Cinta was rescued from an area that had been cleared by an oil palm company. When found, she was apparently motherless, screaming, and shivering.

When she arrived at her rehabilitation facility, she was greeted by a special guest - former President of Indonesia, Megawati Soekarnoputri. The former President named the new baby Cinta, which means 'love' in Indonesian, a fitting name given that her rescue took place on Valentine's Day

MEMA

The Three Squares Inc. (TSI) team adopted Mema through the Borneo Orangutan Survival Foundation, an Indonesian non-profit dedicated to the conservation of the Bornean orangutan and its habitat.

Mema was found by a local villager who claimed to have come across her whilst searching for firewood in a burned peat area. He took Mema to the local village chief, who reported the finding. When found, she was a weak baby weighing only 2.3 kilograms.

Under the care of the Borneo Orangutan Survival Foundation, Mema has developed a playful and friendly nature that allows her to easily make friends with newcomers.
