On April 22, the United States Army will join the Nation in celebrating Earth Day. Army Earth Day 2015 is our opportunity to renew our commitment to sound environmental stewardship of the lands entrusted to us; the lands where our Soldiers, Families and Civilians train, live and work.To ensure the Army continues to remain ready, resilient and capable of accomplishing its mission of defending our Nation, it is especially important that we maintain our commitment to protecting the environment. Our participation in Army Earth Day focuses on inspiring awareness and appreciation of the environment and how it sustains the mission. The Army takes great pride in its commitment to the environment, Acknowledging the Past by restoring Army lands and preserving cultural and historical resources; Engaging the Present by meeting today's environmental standards while enabling Army operations and protecting Soldiers, Families and Civilians, and Charting the Future by using best practices and new technologies to ensure future environmental resiliency.The Army continues to lead the Federal Government through our sustainability initiatives. We reduce, repurpose, recycle at our military installations and maintain our valued partnerships with conservation organizations. We enhance resiliency of our installations through energy efficiency and renewable energy. We are addressing climate change by supporting adaptation efforts to identify and assess the risks of climate change to national security, and we are seeking technological innovations and energy solutions to mitigate climate change by reducing green house gas emissions.As we commemorate Army Earth Day 2015, we encourage everyone to take an active role in sustaining the Earth's resources. Learn more about the Army's environmental initiatives and take advantage of the many opportunities to make a difference on your installation. Support the Army's commitment to maintain a quality environment, secure it for future generations and remain Army Strong!Signed: John M. McHugh, Secretary of the Army Raymond T.
