Examples of green procurement range from the purchase of energy-saving light-bulbs to the commissioning of a new building from renewable sourced timber or organic food being served in a workplace canteen. Sometimes, the ultimate green procurement is the avoidance of the purchase altogether. For example, Seafood Watch lists which commonly consumed fish species are at risk of extinction or population decline, steering conscious consumers towards species with stable populations which can be consumed without threatening their existence or disrupting the ecosystem. Transparency around production can help companies and individuals make more sustainable purchasing choices. In the fashion industry, more consumers and companies are aware of the damage textile dye pollution does to waterways and the communities that rely on them, and as a result, companies and individuals can seek out producers who use natural or nonhazardous dyes.
