• Specify sustainably-grown materials when using paper, cloth, wood, or other organic materials.
• Choose materials based on recyclability, production waste, toxicity, weight, and reusability over renewability.
• Source materials, where possible, with the highest recycled and post-consumer recycled content. 
• Calculate costs and impacts over the product or service’s entire life cycle in order to realize the greatest impacts and benefits.
• Make claims that are transparent and verifiable. If you aren’t going to “show your work” by making available calculations or details, don’t bother making the claim.
• Use independent certification or ratings services where you can afford to do so.
• Become knowledgeable of government and third-party standards in order to make claims honestly and accurately.

This overview of the book’s contents organizes the book’s major principles, sustainability frameworks, and design strategies, indicating where in the development process each is most useful.
 Externalities are basically a cheat. Real markets are incredibly complex—much more so than all economic models. When economics acknowledges the factors that influence real market action (such as the decision-making process customers go through or the social and environmental costs of deforestation) but that aren’t included in economic models, they are referred to as externalities (since they’re missing—or external—to the model). The history of economic models is that the most difficult (and often most important) factors governing economies have been externalities missing from the models used to make economic policy.
Another approach is called total cost assessment. This calculation requires a team within an organization to generate and share data from all areas, including manufacturing, design, R&D, engineering, transportation, marketing, facilities, purchasing, external affairs, inventory, strategy and management (insurance, legal, accounting), and so on. In addition to cur-

 The term eco-efficiency was coined by the World Business Council for Sustainable Development (WBCSD) in its 1992 publication “Changing Course.” Wikipedia.
At its heart, this framework describes four types of capital:
• Natural Capital describes the natural resources we get from the earth. These include physical things, such as materials and energy, as well as processes and effectives, such as ecosystem services and resiliency due to biodiversity.
 Human Capital is the value we get from the work and ideas contributed by people (individuals and society as a whole).
• Manufactured Capital describes the materials and energies people create through
 Shift 1: Radical Resource Productivity is the ability to increase dramatically the productivity of our use of natural resourc – es—and, correspondingly, reduce the material and energy intensity of the products and services we create and use. Though it isn’t specifically mentioned in the framework, this idea is easily extended to all forms of capital, not merely natural capital. Doing more with less has been a tenet of design,

 Modular manufacturing so that several variations of the car can be made on the same factory assembly line
• Paint cured with ultraviolet light instead of high temperatures
 Self-assembly (Many of nature’s solutions, like crystals and DNA, self-assemble without the need for factories.)
 Cleaning without detergents (Leaves, for example, self-clean because of their surface texture, repelling dirt and water.)
• Water-based chemistry
• Metals without mining (Plants and fungi extract metal from their environment without resorting to strip mining or methods that scar the earth.)
 Decentralization and distributed control (Resilient solutions are often decentralized.)
• Simple building blocks (Create deep complexity.)
• Use of feedback loops (Influence, rather than control.)

According to the U. S. Environmental Protection Agency, LCA is “a technique to assess the environmental aspects and potential impacts associated with a product, process, or service by using the following criteria:
• Compiling an inventory of relevant energy and material inputs and environmental releases
 Evaluating the potential environmental impacts associated with identified inputs and releases

Consistent with this book’s approach to design, Edwin Datschefski defines beauty as being inclusive of sustainability. To him, unsustainable products can’t possibly be beautiful. He defines five unique categories of criteria to encompass sustainability concerns, including the following:
 Cyclic refers to solutions that are manufactured in processes that close the loop between resources used and wastes generated. This includes recycling, composting, using organic materials, and stewardship over sustainable sourcing.
• Solar refers to solutions that use renewable sources of materials and energy during the manufacturing and use phases (such
as wind, solar, geothermal, and existing
 Safe is self-explanatory and extends not only to product safety but also to toxicity of materials, concentration, and location. In fact, all releases from the manufacturing, use, or disposal of products to the air, land, water, or space should be safe for people, animals, plants, and the environment as a whole. This concept reflects the under-
 Social refers to the desire for solutions to support basic human rights and “natural justice.” Datschefski doesn’t elaborate and go into as much detail about the myriad social issues described in the previous chapter
 This includes embodied energy. Refer to the LCA framework to appreciate how this must be calculated throughout the life cycle. Renewable sources include solar, wind, muscle, photosynthetic, geothermal, hydro, and wave power.
 However, not all carpet is the same, so these points are crude numbers based on averages and assumptions. Carpet from Interface, for example, is distinguished in every way from carpet produced by the rest of the industry (www. interfacesus- tainability. com).

The Sustainability Helix describes five stages through which an organization progresses from least to most sustainable performance:
• Stage 0: Unsustainable
• Stage 1: Exploration
• Stage 2: Experimentation
• Stage 3: Leadership
 Stage 4: Restoration
At each of these stages, the framework describes measures to assess how well organizations are doing, desired outcomes that describe
The Helix describes an exhaustive list of strategies throughout an organization, including operations strategies such as the following.
Governance and Management Strategies:
• Ethics Strategy
• Project Development Systems
• Risk and Shareholder Value: Insurance Strategy
 Unsustainable Life Cycle Risks Strategy
• Shareholder Value Strategy
• Legal: Regulatory Strategy

 Forgiveness. Systems should help users understand and recover from mistakes easily, such as the near-ubiquitous Undo and Redo commands in computer software.
 Natural Cognitive Structures. The perspective presented of the system, its parts, and its organizational structure should be reasonably accurate, reflect the activities within the system, promote understanding about its use, and reduce the demand for users to memorize actions and behaviors.

 Reclaiming and reusing waste heat from manufacturing for other purposes
The concept of dematerialization considers the materials and energy used throughout the product and service life cycle. At each point, designers have an opportunity to make design choices that optimize the use of materials and energy and reduce the impact of their solutions. Some of these choices include the following.
 Create lighter, smaller products, where possible.
• Minimize the number of components, materials, and type of materials.
 Create packaging made from recycled and recyclable materials that are easily separated.
 Design packaging with labels, graphics, or instructions molded into them that don’t require additional labels to be affixed.
 Use power from renewable sources for online and digital service centers.

 Design an effective, usable system to begin with. Solutions that aren’t usable (which may be discovered only after the product is purchased) often are discarded, entering the waste stream prematurely without providing any value for the energy, time, money, and materials used to create, ship, and sell the device (see Chapter 4, “Design for Use”).
