A view of central South America as seen from the International Space Station. Layers of the Earth’s atmosphere, colored bright white to deep blue, are visible on the horizon (or limb). The highest cloud tops have a reddish glow due to direct light from the setting Sun, while lower clouds are in twilight.

NASA is an expert in climate and Earth science. While its role is not to set climate policy or prescribe particular responses or solutions to climate change, its job does include providing the scientific data needed to understand climate change. NASA then makes this information available to the global community – the public, policy-, and decision-makers and scientific and planning agencies around the world. (For more information, see NASA's role.)

With that said, NASA takes sustainability very seriously. NASA’s sustainability policy is to execute its mission as efficiently as possible. In doing so, we continually improve our space and ground operations.

Sustainability involves taking action now to protect the environment for both current and future living conditions. In implementing sustainability practices, NASA supports its missions by reducing risks to the environment and our communities.

In executing its mission, NASA's sustainability objectives are to:

  • increase energy efficiency;
  • increase the use of renewable energy;
  • measure, report, and reduce NASA's direct and indirect greenhouse gas emissions;
  • conserve and protect water resources through efficiency, reuse, and stormwater management;
  • eliminate waste, prevent pollution, and increase recycling;
  • leverage agency acquisitions to foster markets for sustainable technologies and environmentally preferable materials, products, and services;
  • design, construct, maintain, and operate high-performance sustainable buildings;
  • utilize power management options and reduce the number of agency data centers;
  • support economic growth and livability of the communities where NASA conducts business;
  • evaluate agency climate change risks and vulnerabilities and develop mitigation and adaptation measures to manage both the short-and long-term effects of climate change on the agency's mission and operations;
  • raise employee awareness and encourage each individual in the NASA community to apply the concepts of sustainability to every aspect of their daily work to achieve these goals;
  • maintain compliance with all applicable federal, state, local or territorial law and regulations related to energy security, a healthy environment, and environmentally-sound operations; and
  • comply with internal NASA requirements and agreements with other entities.
