Smart Air

Smart Air is a certified social enterprise, founded in 2014 in Beijing, China, and is the first and only certified B-Corp tackling air pollution. Their mission statement is to protect people from the harms of polluted air through education and the shipment of cost-effective purifiers and clean air tools.

Founding Story

In January 2013, Beijing was facing an ‘airpocalypse’ with record-high pollution levels. Smart Air founder Thomas Talhelm was a PhD student living in Beijing at that time. When looking at how protect his health, Thomas was shocked to discover how expensive purifiers were.

He did some research, and found that air purifiers are just fans and filters – nothing complex. He purchased a HEPA filter and strapped it to a fan, creating his first ‘DIY air purifier’. After running hundreds of tests, the data showed that DIY purifiers are just as effective as the more expensive purifiers. Armed with this data, Thomas decided to show and teach the world how make an air purifier for under $30. Thomas is now an assistant professor at U Chicago Booth, and Smart Air has grown to be a global social enterprise with an expanded range of purifiers and clean air tools, and an ever increasing database of educational topics to keep people safe from air pollution.

Through SROI

What is SROI?

Social return on investment (SROI) is an outcome-based measurement tool that helps organizations understand and quantify the social, environmental, and economic value from their activities. Developed from traditional cost-benefit analysis, SROI provides an organization a narrative of how their activities create value while making change in the world using a ratio stating how much social value is created for 1 USD invested.

The method revolves around a six-step methodology:
  • Establishing scope and identifying key stakeholders
  • Mapping outcomes to show the relationship between inputs, outputs, and outcomes from each initiative
  • Monetizing outcomes by putting a financial value on the activities
  • Establishing impact by identifying which outcomes are mainly the result of the firm’s initiatives
  • Calculating the SROI by adding up all the benefits and comparing them to the initial investment
  • Sharing the findings and recommendations with stakeholders

Summary: Smart Air’s Approach

Smart Air’s performance in tackling air pollution issues can be broken down into a logical framework, which summarizes the key elements of Smart Air’s model to be used for future project monitoring and evaluation. By listing the activities, outputs, outcomes, and the goal (or expected impact), it shows the logic of how the activities will lead to outputs, which in turn lead to outcomes, and in the end, how those initiatives create value for the firm, its stakeholders, and its community.
