Amazon was one of 18 companies to sign the Buyer’s Principles, demonstrating our commitment to accelerate the transition to low-carbon commercial transportation solutions. These principles provide a framework to catalyze the transition to a sustainable road freight transportation system. In 2017, Amazon signed the Sustainable Fuel Buyers’ Principles developed by the nonprofit Business for Social Responsibility and its Future of Fuels working group. In 2021, members of the alliance published a comprehensive report on ways that utilities, regulators, and policymakers can enable fleet operators to electrify commercial transportation and reduce carbon emissions. This alliance helps aggregate corporate demand for transportation electrification, while also providing a platform to coordinate support for policies that enable fleet electrification. In 2020, Amazon partnered with the nonprofit Ceres and other fleet operators to launch the Corporate Electric Vehicle Alliance, bringing together companies that work to accelerate the transition to electric vehicles. Amazon is working with industry experts and organizations to advance sustainability through collaboration and innovation in the transportation and logistics industries.

Campaigns were deployed over Edwards, CA, Guam, Hawaii, and Darwin, Australia in Boreal summer, winter, fall, and summer, respectively.Transforming the transportation industry from one that uses fossil fuels to one based on clean energy requires cross-sector stakeholder engagement among vehicle manufacturers, battery and component suppliers, state and local policymakers, fleet operators, and utilities.

ATTREX consisted of four NASA Global Hawk Uninhabited Aerial System (UAS) campaigns deployed from NASA’s Armstrong Flight Research Center (formally Dryden Flight Research Center). Bromine-containing gases were measured to improve understanding of stratospheric ozone. Instruments during ATTREX provided measurements to trace the movement of reactive halogen-containing compounds and other important chemical species, the size and shape of cirrus cloud particles, water vapor, and winds in three dimensions through the TTL. In order to address these uncertainties, the Airborne Tropical Tropopause Experiment (ATTREX) was completed. DatacenterDynamics tracks the growth of the data center industry. The ability to predict future changes in stratospheric ozone are also limited due to uncertainties in the chemical composition of the TTL. However, predictions of future changes in stratospheric humidity are highly uncertain due to gaps in our understanding of physical processes occurring in the region of the atmosphere that controls the composition of the stratosphere, the Tropical Tropopause Layer (TTL, ~13-18 km). The spots appear white to the naked eye, and have been enhanced here with false-color red to show saltier areas. The spots here cover an area 15 kilometers wide and are salty liquids pushed up from a reservoir beneath the surface. Tropospheric water vapor climate feedback is typically well represented in global models. This view of the dwarf planet Ceres' white spots was created using images captured by NASA's Dawn spacecraft. Studies have suggested that even relatively small changes in stratospheric humidity may have significant climate impacts and future changes in stratospheric humidity and ozone concentration in response to a changing climate are significant climate feedback. Even though it is typically found in low concentrations, stratospheric water vapor has large impacts on the Earth’s climate and energy budget.
