Who We Are

Triple Bottom Line AEPI assists the Army Secretariat in developing policies and strategies to improve or resolve environmental policy issues that may have significant short or long-term impacts on the Army. Since environmental issues continue to emerge as our knowledge and technology develop, AEPI constantly scans for and assesses future environmental challenges and opportunities for the Army.

Our overall objective is to support the triple bottom line of Army sustainability - Mission, Environment, and Community - as outlined in the Army Strategy for the Environment. Our initiatives help the Army to sustain readiness, improve quality of life, strengthen community relationships, and help reduce total costs of ownership by suggesting sound environmental investments for force transformation and installation sustainability.

Army Strategy for the Environment

Army Strategy for the EnvironmentThe United States Army has long recognized that our mission is only accomplished because America entrusts us with its most precious resources - its sons and daughters. It is our obligation to ensure that our Soldiers today - and the Soldiers of the future - have the land, water, and air resources they need to train; a healthy environment in which to live; and the support of local communities and the American people… read more

Army Sustainability Report 2007

Army Sustainability Report 2007In June 2007, Army Headquarters received one of three White House Closing the Circle "Sowing the Seeds of Change" Awards from the Office of the Federal Environmental Executive for the future vision established and implemented through our sustainability strategy—The Army Strategy for the Environment (ASE): Sustain the Mission, Secure the Future. Through this strategy, released in 2004, Army leadershp challenged all Army personnel to incorporate our 'triple bottom line' (TBL) of Mission, Environment, and Community into all of its plans, processes and actions. The principles laid out in the Strategy provide a compass, pointing to a true north, which will continue to guide us well into the 21st Century as we navigate the terrain toward sustainability… read morepublication (PDF)brochure (PDF)

Quantifying the Army Supply Chain Water Bootprint

cover image of Quantifying the Army Supply Chain Water Bootprint reportWater is highly likely to become a focus of future competition and conflict sparked by increased demand and dwindling availability. Projected climate changes will likely exacerbate water scarcity in high-risk areas. Army policy does not address supply chain or indirect water use, and, suppliers and most of industry do not track their own indirect water use or water used to manufacture products. The Army undertook this water bootprint study as an initial step toward quantifying the amount of water used by suppliers to produce the goods and services it procures through the supply chain. A primary concern driving the study is that timely provision of critical goods and services could be at risk if water-intensive production lines suffered unforeseen water shortages. To calculate the water bootprint for the supply chain, the authors applied water-use factors to known quantities of purchased fuels and utility energy, and a high-level economic model that estimates water use per million dollars of activity by market sector to the remaining supply chain components. The latter includes data from requisition and acquisition databases, local purchases, and military and civil works construction and, international and interagency support provided by the US Army Corps of Engineers. The study findings will help the Army make supply-side policy decisions before water availability issues can adversely affect critical supplies and services, thus hindering operational readiness and training… read more (PDF)

Army Foresight: Protecting Critical Benefits Received from Ecosystems

cover image of June 2011 Army Foresight reportEcosystem services are the benefits people receive from ecosystems, but their value are often underestimated or ignored, making them difficult to protect. Ecosystem services benefit the Army mission by supplying land and habitats for realistic training, filtering pollutants from stormwater, providing noise, safety, and smoke buffers, and providing valuable recreational opportunities for soldiers, their families, and community members. The report proposes a “no net loss” of ecosystem services policy would be consistent with regulatory approaches on wetlands, and is compatible with the Army’s “Net Zero” concepts for energy, water, and waste.… read more (PDF)

cover image of AEPI Sustainability Analysis FinalAn analysis was performed to indentify the existing regulatory, policy, doctrinal, conceptual, or guidance documents related to sustainability or environmental considerations that could be either directly or indirectly linked to contingency operations. Environmental considerations were included in order to assure that references to environmental sustainment were not overlooked with reference to operational sustainability. None of the documents are directed at implementing or developing sustainability as a driving factor in contingency operations.… read more (PDF)

Water Sustainability Assessment for Ten Army Installations

cover image of ERDC-CERL_TR-11-5-Water-Sustainability-Assessment-for-Ten-Army-InstallationsA key concern for the US Army is the vulnerability of military installations to critical resource issues. Water issues of concern, including adequate supply, increased cost of production per unit volume, quality, habitat degradation and salinity issues, already affect military installations and military operations in many locations within the nation and across the globe. There is a need to assess vulnerability of regions and installations to water supply and to develop strategies to ameliorate any adverse effects on military sustainment. These analyses, completed on a watershed level and projected over a 30-year time frame, include estimates of both installation and regional water demand. Assessments were completed for 10 Army bases across the United States. Results depict a range of installation water sustainability conditions that reflect the larger picture of water sustainability across the United States and around the world. The Army is applying the results of these studies to develop policies that will support sustainable long-term water supplies.… read more (PDF)

Fully Burdened Cost of Waste Report

cover image of FULLY BURDENED COST OF MANAGING WASTE IN CONTINGENCY OPERATIONS Final Technical ReportA method and spreadsheet-based tool are presented to determine the fully burdened cost of managing solid, hazardous, and medical waste in contingency operations. Understanding that Army materiel costs more than the price charged at commodity procurement and that there are non-monetary risks and liabilities form the "fully burdened" cost (FBC) concept. The FBC method accounts for differences in waste management costs as military operations mature from initial deployment to stabilization and reconstruction. It begins with the waste as already generated and does not address materiel or operational decisions that influence the waste stream… read more (PDF)

Environmental Factors in Forecasting State Fragility

ENVIRONMENTAL FACTORS IN FORECASTING STATE FRAGILITYThe current state of both instability and fragility early warning systems were researched to assess their capabilities to account for environmental factors. An exploratory quantitative analysis of the effects of environmental variables on fragility indices was conducted using fragility as the dependent variable. Alternative architectures were also evaluated that could be leveraged in a paired instability and fragility approach, utilizing quantitative and qualitative data, for use in actionable early warning frameworks supportive of U.S. Army, defense, and national security missions.

Army Installations Water Sustainability Assessment

Army Installations Water Sustainability AssessmentThe U.S. Army is concerned that its installations face multiple critical resource issues, including water. Adverse water issues include supply, cost, and quality. Strategies are needed to mitigate these adverse effects. To develop these strategies, information was gathered from national watershed screenings and regional water budgets including supply and demand data from regions with Army installations. The information was then used to develop installation water demand projections that look beyond the fenceline and out 30 years into the future to identify the potential for water scarcity. read more (PDF)
