Human health and well-being Human health and well-being

Healthy individuals are a foundation of a healthy society. Human health includes elements of preventive care, chronic disease treatment, and mental health support. Companies that support human health include conventional healthcare products and service providers as well as those that focus on holistic wellness through nutrition and fitness.

Equity and access Equity and access
Efficiency and effectiveness – Business processes

Healthy systems and societies are the connection between the health of individuals and the health of the planet. At this connective layer, we consider two major sets of topics and the companies that address them: First, access to information and opportunity, security and data privacy; and, second, efficiency and effectiveness across all types of operations and systems.

Environmental health Environmental health

A healthy planet supports all human activity. The effects of climate change — extreme weather events, temperature change, and ocean and soil degradation — are becoming more visible and more acute. As a result, many companies are building climate resiliency into their business models while others are focused on creating solutions to mitigate climate change and its impacts.
