Design for Sustainable is the philosophy of designing physical objects, the built environment and services to comply with the principles of economic, social, and ecological sustainability.

The intention of sustainable design is to "eliminate negative environmental impact completely through skillful, sensitive design". Manifestations of sustainable designs require no non-renewable resources, impact on the environment minimally, and relate people with the natural environment.

Applications of this philosophy range from the microcosm — small objects for everyday use, through to the macrocosm — buildings, cities, and the earth's physical surface. It is a philosophy that can be applied in the fields of architecture, landscape architecture, urban design, urban planning, engineering, graphic design, industrial design, interior design, and fashion design.

Sustainable design is mostly a general reaction to global environmental crises, the rapid growth of economic activity and human population, depletion of natural resources, damage to ecosystems and loss of biodiversity.

The limits of sustainable design is reducing whole earth impacts are beginning to be considered because growth in goods and services is consistently outpacing gains in efficiency. As a result, the net effect of sustainable design to date has been to simply improve the efficiency of rapidly increasing impacts. The present approach, which focuses on the efficiency of delivering individual goods and services does not solve this problem. The basic dilemmas include: the increasing complexity of efficiency improvements, the difficulty of implementing new technologies in societies built around old ones, that physical impacts of delivering goods and services are not localized but distributed throughout the economies, and that the scale of resource uses is growing and not stabilizing.

The motivation for sustainable design was articulated in E. F. Schumacher's 1973 book Small Is Beautiful. In architecture, sustainable design is not the attachment or supplement of architectural design, but an integrated design process. This requires close cooperation of the design team, the architects, the engineers and the client at all project stages, from the site selection, scheme formation, material selection and procurement and project implementation.
