Environment metrics basically measures how well a company performs as a steward of the environment.
Climate change is a significant change in climate patterns, primarily due to higher levels of atmospheric carbon dioxide produced when fossil fuels are burned. These changes can result in extreme weather events that significantly impact businesses and communities, not to mention the effect on future generations.
A carbon footprint is the amount of carbon dioxide emitted, for example by a company in the process of doing business.
The waste stream is the full cycle of waste from product creation through disposal. Examples of waste include paper, plastics, metal, glass, and hazardous material.
