Earth Day is celebrated each year on April 22 to remind us of our responsibility to protect and preserve the environment. NASA’s Glenn Research Center in Cleveland is committed to environmental stewardship through robust conservation and sustainability practices. We’ve made great strides in areas such as natural resource management, renewable energy, sustainable transportation and fuel, and energy systems integration, and under NASA 2040, we continue to invest in modernization to reduce our energy usage and introduce more green space. By investing in our planet, we’re investing in ourselves and future generations who will help us carry on NASA’s important mission.
