Definitions of Sustainability
Conventional Definitions Brundtland Commission
“Development that meets the needs of the present without compromising the ability of future generations to meet their needs.”
ISO “actions of an organization to take responsibility for the impacts of its
activities on society and the environment . . . based on ethical behavior, compliance with law, and intergovernmental instruments, and . . .integrated into the ongoing activities of an organization.”
Variations on this theme for the Services U.S. Army triple bottom line: mission, environment, and community

Mandatory Presidential Executive Order 13514 USEPA GHG Reporting Rule (40 CFR Part 98)
Stakeholder Interests Taxpayer
› Fiscally responsible: value creation and cost reduction
› Assured supply and price predictability
› Global sourcing and environmental justice issues Workforce needs and development Community Local approvals
The Environment Assured supply of natural resources: water, energy and materials
› Impact of climate change

Drivers
Scope Sub-Category Examples
Scope 1: Direct emissions from combustion at facility
Stationary On-site boilers, turbines, furnaces, process heaters
Mobile Vehicles, vessels, aircraft, off-road equipment
Process Dry ice, other processes directly using GHGs
Fugitive Refrigerant leakage
Scope 2: Indirect emissions
Purchased utilities (i.e., not produced on-site)
Purchased electricity, steam, heat, chilled water
Scope 3: Other indirect emissions
Employee commuting, official travel
Travel using non-facility vehicles, vessels, aircraft
Solid waste Waste sent to landfills
Supply chain Emissions in manufacture/ transport/ use/ disposal of procured products
USEPA Rulemaking
USEPA Mandatory GHG Reporting Rule Applicable to all facilities (including military) with emissions of ≥25,000
metric tons carbon dioxide equivalent per year (MTCO2E/yr)
› Military: General stationary combustion only› Civilian: Stringent requirements for certain types of industries and
suppliers Use of different reporting tiers based on energy output and fuel type GHG tracking to begin 01/01/2010
› First report to USEPA due 03/31/2011 USEPA Endangerment Finding
Follow up to 04/02/07 Supreme Court ruling – CO2 as “air pollutant”
Gives USEPA authority to regulate CO2 emissions under the Clean Air Act

Water & Waste
Source minimization, reuse, and recycle
Water and Sewer Usage Are you doing everything possible to minimize the use of water at your Base
(e.g., waterless devices or low-flow fixtures), along with the resulting waste streams associated with water use?
Printing and Packaging Can you reformulate your printed materials and packaging to eliminate all but
the absolutely necessary elements and utilize recycled materials? Are all printers configured for double-sided and reduced size printing?
Waste Minimization and Commodity Management Do you have a comprehensive waste minimization policy and program? Do you have effective programs in place to recover and recycle or reuse
valuable commodities and reduce solid waste streams?

racks to:› reduce discharge to the sanitary system› conserve water (used for washing) due to a Base-mandated goal for
overall reduction ~60,000 gal/yr saved for sanitary and water combined

Procurement & Supply Chain
EO 13514 Ensure that 95% of new contract actions (except weapons systems) are energy-
efficient, water-efficient, biobased, environmentally preferable, non-ozone depleting, contain recycled content, and/or are non-toxic or less-toxic alternatives
Procurement What are your primary purchases? Are there alternative materials that are more environmentally friendly and provide
no worse than a cost-neutral comparison to current materials? Are you using recycled materials wherever possible? Have you asked your suppliers to provide environmentally friendly options or
alternatives where feasible? Supply Chain Consideration
Can you spell out your sustainability-related requirements? Can you incentivize/influence your suppliers to meet these requirements?

Sustainability through “de-construction”
Deconstruction is the process of dismantling a building in order to salvage components for reuse and recycling
Fundamentally change notions about commerce and its role in shaping future
27
Demolition Deconstruction
Highly Mechanized Labor Intensive
Capital Intensive Low-Tech
Waste Generating Material Reuse
Deconstruction is the sustainability preferred option.

Sustainable Remediation
Environmental cleanup that is able to evaluate whether benefits outweigh remediation costs; ensure the environmental impact of the remediation activity is
less than the impact of leaving the land untreated; engage all stakeholders in the decision-making process; minimize or eliminate energy and natural resources
consumption; reduce or eliminate releases to the environment; harness or mimic natural processes; use renewable energy sources; and use recyclable materials.

EO Compliance
EO 13123 Compliance Study - Robins AFB, Georgia
EO 13123 required that all DOD facilities:
1. Reduce their energy consumption by 20% by the year 2005;
2. Increase production flexibility by reconfiguring or upgrading the facility infrastructure to maximize utility and space flexibility and to accommodate the continually variable operations of this facility;
3. Lower maintenance costs through the repair or replacement of facility equipment
Capital and 20-year life cycle implementation costs used
Assessments conducted:› Potential to incorporate green products into the renovation› Impact to facility’s LEED score through the application of various
renovation scenarios
