This keynote address discusses the importance of considering social and environmental impacts beyond just financial returns when investing in clean technology. The speaker notes that while cleantech aims to be environmentally positive, production processes sometimes use toxic chemicals or have negative social consequences that could damage the brand. The cleantech industry needs to avoid repeating the mistakes of other sectors and proactively adopt best practices to advance social justice, employee welfare and reduce toxics. Considering these "triple bottom line" factors of people, planet and profit is important to attract sustainable investment and build truly great companies of long-term value.
