Clarke, a mosquito abatement company seen as having a core business that is environmentally harmful by its very nature — selling pesticides — faces unique challenges in its transformation into a sustainable enterprise. Should it shift its focus entirely towards offering “green” pesticides and risk losing some of its customers, or should it keep offering its less expensive, more toxic products? This case shows how even when innovation leads to new green products, processes, technologies, and business models, the leadership of a company must cope with the daunting task of engaging employees and customers in the idea that green can be effective and profitable.

Companies in every industry are attempting to reduce their use of chemicals, particularly synthetic organic compounds, where there is a perception of harm to human health or the environment. The industrial and commercial floor-cleaning equipment industry is no different, with many equipment manufacturers seeking to reduce their use of harsh cleaning chemicals such as petroleum solvents. But with every competitor pursuing similar greening efforts in a mature market, companies find it difficult to differentiate their offerings to customers. <br><br>Tennant Company chose to differentiate itself through a technology-driven business strategy based on chemical-free cleaning. Instead of reducing the use of harsh cleaning chemicals, or reducing the harshness of those chemicals, Tennant offered its customers a cleaning solution that used ionized tap water to clean and disinfect surfaces, thereby eliminating harsh chemicals altogether. The benefits to customers were numerous, including lower total cost of ownership and improved health and safety, while maintaining cleaning performance relative to conventional chemical-based products. This case helps to illustrate the challenge of profitably going beyond incremental “greening” efforts (aimed at doing less harm) — could a significant innovation in environmental performance be the central argument for the company’s value proposition?
