摘要：Sustainable development has been an internationally
recognized aim since the UN Conference
on Environment and Development
in Rio de Janeiro in 1992. Its central challenges are
the maintenance of social security and justice, sustainable
economic development, and the preservation
and creation of an intact environment. Looking
at industrial sectors, the construction sector is
of particular importance. On one hand, it makes
a vital contribution to the social and economic
development of every country by providing housing
and infrastructure; on the other, this sector is
an important consumer of non-renewable
resources, a substantial source of waste, a polluter
of air and water, and an important contributor to
land dereliction. Material flows analyses for Germany,
Japan and the United States show that the
construction sector accounts for between onethird
and one-half of commodity flows when
expressed in terms of weight (Figure 1).1
