Chief executive of online retailer Amazon.com, Jeff Bezos, set the company planned to cut down its greenhouse emissions caused by its delivery operations. However, data provided by Reuters show that the use of aeroplanes for deliveries of Amazon packages is increasing. Aeroplanes are considered the most climate-damaging transport. Volume from the United States in Amazon Air has continuously increased since 2016 according to data that was received from Atlas Air Worldwide Holdings and Air Transport Services Group Inc, both of which provide planes and pilots to Amazon Air. During the month of July, Amazon Air transported 136 million lbs of packages in the US. As compared to July last year, the growth in goods transported through air increased by 29 percent. Amazon CEO had earlier said that the company would try to reduce its usage of aeroplanes by constructing more local warehouses. This would also be beneficial as the company would be able to deliver packages to its customers within a day, he added. However, packages being transported through the air are increasing. This comes as the company tries to attract customers from competitors like Walmart Inc and Target Corp. Besides that, the e-commerce giant is also offering one-day free delivery to its Prime subscribers. It warned during the holiday quarter that delivery costs could amount to $1.5 billion for just the one-day delivery offer. Amazon did not provide information on the proportion of its packages that are delivered through air transport. It also did not mention how the removal of its standard to delivery affected air transport. The company delivers about 10 billion packages each year. In 2018, the online retailer's CO2 emissions amounted to 44.4 million metric tons. Amazon CEO set a goal last month to make the company's delivery operations net carbon neutral by 2040.
