14 “Brownfield” refers to sites that are often difficult to use for other purposes due to contamination, the presence of hazardous substances (for example, former gas stations and landfills). Development of these sites often requires significant investments in pre-development cleanup, revitalization, and monitoring to remain in compliance with local laws. Cloud providers are well-positioned, due to their size and affluence, to overcome these hurdles, reducing the development pressure on “greenfield” sites, undeveloped land that may be used for agricultural purposes.
