Environmental Sustainability is often defined as "development that meets the needs of the present without compromising the ability of future generations to meet their own needs."
By any definition, asphalt is the sustainable material for constructing pavements. From the production of the paving material, to the placement of the pavement on the road, to rehabilitation, through recycling, asphalt pavements minimize impact on the environment. Low cost over the pavement's life cycle, low consumption of energy for production and construction, low emission of greenhouse gases, and conservation of natural resources help make asphalt the environmental pavement of choice.
Above all, what makes asphalt sustainable is the fact that only asphalt can be a perpetual pavement. Today's asphalt pavements can be designed literally to last in perpetuity. Total pavement reconstruction is rendered virtually obsolete with a perpetual pavement.

The American Concrete Pavement Association has made several statements about sustainabilty of asphalt pavements that need to be addressed. Here are some of ACPA's statements and NAPA's factual responses.
