双语：新研究称这种快递购物更环保（含课件）

物流工作人员正在分拣快递

而一项新的研究证实，快递购物的方式可能比你想象中更加环保，一起来看一看吧！

Local deliveries are associated with lower emissions than online-only and in-person shopping.Customers can reduce their carbon footprints by ordering items online for delivery from a local supermarket, rather than shopping through an online-only retailer or making a trip to the store, a new study suggests.

与在线购物和亲自购物相比，本地送货与更低的排放量相关。一项新的研究表明，消费者可以通过 上订购商品，从当地超市送货，而不是通过仅限在线的零售商购物或去商店购物，从而减少碳足迹。

Computer simulations of shopping trips and deliveries in the United Kingdom allowed researchers to estimate the carbon emissions associated with each item purchased through different means. On average, deliveries by a local shop per item as deliveries by online-only retailers, which deliver items through package distribution centers, researchers report online February 26 in Environmental Science & Technology. Local deliveries also produce lower emissions than in-person shopping.

通过对英国购物和送货的计算机模拟，研究人员可以估算出通过不同方式购买的每件商品的碳排放量。研究人员2月26日在《环境科学与技术》杂志在线版上发表 告称，平均而言，当地商店送货产生的每件商品的二氧化碳排放量不到纯在线零售商送货的一半，后者通过包裹配送中心送货。当地送货也比亲自购物产生更低的排放量。

on average 平均

Greenhouse gas emissions associated with local store deliveries averaged about 0.07 kilograms of CO2 per item, compared with 0.1 kilograms for in-person shopping.

与当地商店送货相关的温室气体排放量平均约为每件商品0.07千克二氧化碳，而亲自购物的排放量为0.1千克。

Environmental scientist Sadegh Shahmohammadi and colleagues simulated thousands of instances of someone purchasing a cartful of items, such as personal care and houseware products, either in-person or online. To reflect real-world shopping and delivery conditions, the team took into consideration the factors in emission estimates for activities such as powering storage warehouses, transporting items in different types of vehicles and walking versus driving to a store.

环境科学家Sadegh Shahmohammadi和他的同事们模拟了数千个例子，一个人亲自或在线购买了一车物品，比如个人护理用品和家庭用品。为了反映现实世界中的购物和送货情况，研究小组考虑了为仓库供电、用不同类型的车辆运输物品以及步行和开车去商店等活动的排放量估算因素。

take into consideration 考虑到……

Deliveries by local shops tend to be greener than those from online retailers because people ordering from a single store usually buy a bunch of stuff at once, explains Shahmohammadi, who worked on the research while at Radboud University Nijmegen in the Netherlands. Online retail shoppers, on the other hand, often get items delivered one at a time — contributing to a higher carbon footprint over multiple deliveries.

在荷兰奈梅亨大学从事这项研究的Shahmohammadi解释说，当地商店的送货方式往往比 上零售商的送货方式更环保，因为人们通常一次从一家商店订购一大堆东西。另一方面，在线零售购物者通常一次只送一件商品，这导致了碳排放量更高。

Bundling items for single delivery could help online shoppers reduce their carbon emissions, the authors say. Meanwhile, in-person shoppers can shrink their footprints by cycling to the shop instead of driving.

研究者称，将商品捆绑在一起，一次送货上门可以帮助 上购物者减少碳排放。同时，亲自购物者可以通过骑自行车去商店而不是开车来减少他们的碳足迹。
