The Perishable Cargo Regulations manual is an essential reference guide for all parties involved in the packaging and handling of temperature-sensitive products. For more information on sustainability concerns specific to transporting perishables, please read the new Sustainability Considerations for Perishable Cargo Transportation (pdf). "Dynamic pricing would likely lead to much larger reductions in retailer food waste.The new Perishables Logistics and Air Transport whitepaper (pdf) explores the unique challenges of perishables transport by air and draws attention to the efforts and initiatives undertaken by the air cargo supply chain to address them. "Of course, waste bans could still be helpful if businesses comply and divert waste from the landfills, but the best and first thing to do is reduce the overall amount of waste generated to begin with," Sanders said. Shoppers can find products that are near or past their expiration dates along with out-of-season products, overstocked items and imperfect produce, baked goods and meat.ĭynamic food pricing certainly isn't the sole solution for battling the ongoing climate crisis, but it's a step in the right direction. These stores are essentially "a kind of discount retail store that offers food products that traditional grocery stores are unwilling (or unable) to sell," per Taste of Home. Just take a look at salvage grocery stores, which exist to help cut food costs and reduce food waste. Want more great food writing and recipes?

"It is also a market-based solution that the retailer's themselves could implement." "If regulators want to directly reduce grocery-store waste, they should incentivize grocery chains to adopt dynamic pricing over imposing organic waste bans or waste taxes," Sanders added. It's also more effective than a strict organic waste ban (which reduces waste by only 4%) and makes perishables more affordable for and accessible to consumers. Sanders found that dynamic pricing, on average, reduces waste by 21% while increasing grocery chain's gross margins by 3%. "However, this research shows that the increased price flexibility of discounting food that is about to expire significantly reduces food waste and increases profit margins among retailers." grocery retailers offer any kind of dynamic pricing at all, while most hotels and airlines will discount rooms and seats when they have a surplus," said Robert Sanders, an author of the study and assistant professor of marketing and analytics at the Rady School. Collectively, global food waste releases up to 10% of worldwide annual greenhouse gas emissions, which in turn intensifies global warming and climate change.įood expiration dates don't have much science behind them - a food safety researcher explains When organic wastes decompose, they release methane, a potent greenhouse gas. In fact, "when gross profit margins are higher, the retailer stocks its shelves more fully to make sure it doesn't miss out sales, but as a result, waste increases." However, such high amounts of food waste also lead to several environmental consequences. The study showed that grocers are more inclined to produce high amounts of waste because it's profitable to do so. More than 10% of food waste comes from grocery retailers that throw out surplus perishables past their expiration date. This allows grocers to change the price of food throughout the day - instead of maintaining a fixed, daily price - beginning from when foods arrive on the shelf until they expire. The practice encourages retailers to establish a system that determines when grocery stores should reduce the price of perishables depending on their inventory and expiration date. A new study from the University of California San Diego's Rady School of Management found that dynamic food pricing could help keep more perishable items out of landfills, reducing food waste by 21% or more.
