Greenroads is best described as which of the following?

• A. For-profit firm that evaluates traffic efficiency
• B. Government agency that certifies roadway safety
• C. Non-profit that ranks roadways and infrastructure on sustainability
• D. Academic researchers studying pavement materials

Answer: (C)

Greenroads is a non-profit organization that provides a sustainability rating system for roadways and related infrastructure. It evaluates projects against a structured set of criteria—covering environmental impact, materials and construction practices, water management, social and economic factors, and access—and then ranks and certifies how sustainable a project is. This focus on rating and certifying sustainability, rather than profit-making, government regulatory authority, or purely academic study, is why the description of a non-profit that ranks roadways and infrastructure on sustainability is the best fit.
