The trend toward online shopping is credited with being a positive impactor on overall environmental emissions, as it eliminates the need for large, energy-consuming, retail stores. However, recent carbon emission estimates show that
as a result of this trend, per capita levels of purchase-related emissions have risen by over 5%, after adjustments to account for spending patterns. Shipping emissions, the energy consumed warehousing goods, and packaging have all been cited as contributors. So,
