Climate positive

Between fiscal years 2007 and 2017, ASU reduced its net greenhouse gas emissions by 31.3 percent. This reduction was achieved as ASU increased gross square footage by 33.1 percent and its on-campus population by 29 percent during this same period. The net effect is a reduction in GHG emissions per gross square foot by 48.4 percent and per on-campus student by 46.7 percent. ASU utilizes a portfolio approach to address GHG reductions as emissions are generated by many sources.


  • Achieve carbon neutrality for Scope 1 and 2 emissions by FY 2025.
  • Achieve carbon neutrality for Scope 3 emissions by FY 2035.
  • Develop climate-related education, research and community engagement “handprint” goals and metrics with a particular focus on social equity by Dec. 31, 2018.

Energy efficiency and conservation 

日本一本道a不卡免费As energy use is the largest component of ASU’s GHG emissions inventory, energy efficiency is essential to reducing our footprint. Even before it officially made its climate commitment, ASU reduced its overall energy consumption by implementing both large- and small-scale efficiency projects. The two largest projects were Energy Services Performance Contracts totaling about $73 million, which led to the implementation of numerous energy conservation measures, including heating, ventilating and air conditioning renovations and upgrades, lighting projects and more. 

日本一本道a不卡免费These large performance contracts largely sought the low hanging fruit, allowing ASU to make a significant early impact on its carbon footprint. ASU implemented numerous smaller projects focusing on individual buildings or systems. Much like the performance contract projects, these involved improvements to lighting and heating, ventilating and air conditioning systems.

日本一本道a不卡免费ASU is currently implementing many additional Energy Conservation Measures throughout its various campuses. Projects include lighting, mechanical, electrical, infrastructure, utility and overall building improvements.

Energy conservation

In addition to efficiency improvements, ASU utilizes behavior change for energy conservation purposes – reducing an activity to reduce energy resource use:

Room temperature conservation guidelines

ASU currently specifies that classrooms and offices are heated to no higher than 68 F, and cooled to no lower than 80 F. These guidelines reduce space conditioning, thus reducing the amount of energy used.

Energy monitoring

ASU has installed additional meters to monitor ASU’s energy use since 2007. Energy monitoring is essential to identifying energy efficiency opportunities in locating wasteful practices and inefficient operations, as well as determining progress. In addition, ASU implemented Campus Metabolism, an interactive web tool that displays historical and real-time energy use and generation on campus, informing and educating the ASU community through dashboards, graphics and simulations.

Progress charts 

ASU has made significant progress on greenhouse gas emissions reductions, despite dramatic growth in campus populations and facilities space.

Purchasing measures

ASU implemented sustainable purchasing policies日本一本道a不卡免费 and practices that have been recognized twice by the Association for the Advancement of Sustainability in Higher Education for top achievement among reporting universities. Relative to minimizing emissions, practices include requiring EPEAT Gold for all computer purchases, the highest EPEAT standard available for television monitors, Energy Star certification for all products and materials eligible and a minimum of 30 percent recycled content for purchased paper. In practice, over 41 percent of paper purchased is 100 percent recycled.

Transportation measures 

ASU provides transportation options to meet climate positive goals. Since 2007, ASU has implemented:

  • 24,000 bike parking spaces and a free bike valet program with the effect of increasing on-campus bicycles by 27 percent and reducing residence hall student vehicles from 44 percent in 2005 and 2006 to 16 percent in 2015 and 2016

  • a car-sharing program

  • 日本一本道a不卡免费an air travel carbon fee that is used to plant trees through an urban forestry program

  • 日本一本道a不卡免费alternative fuel vehicles and a biodiesel station

  • 日本一本道a不卡免费electric vehicle charging stations

  • 日本一本道a不卡免费free intercampus shuttles

  • pedestrian transportation promotion

  • subsidization of city of Tempe neighborhood Orbit buses

  • Valley Metro light rail ridership promotion by subsidizing 1.7 million one-way trips per year

日本一本道a不卡免费ASU continues to reduce Scope 3 emissions while improving transportation options with new initiatives such as departmental car sharing, additional electric vehicle charging stations, rideshare partnerships and plans for departmental cart sharing.
