These terms refer to the ability of trees and vegetation to remove pollution from rain water. Green roofs and shade trees, for example, mitigate urban runoff and nonpoint source nitrogen and phosphorus pollution through these processes.

EPA's Brownfields Initiative works with public, private and non-profit partners to sustainably reuse sites whose redevelopment may be complicated by the real or perceived presence of contaminants.

Building green is the practice of increasing the efficiency with which buildings and their surrounding property use and harvest energy, water, and materials. Green building is also the practice of protecting and restoring human health and the environment, throughout the building life-cycle: siting, design, construction, operation, maintenance, renovation and deconstruction.

The term cool roof is used to describe roofing material that has high solar reflectance. This characteristic can reduce heat transfer to the indoors and enhance roof durability. Cool roofs may also be highly emissive, releasing a large percentage of the solar energy they absorb.

A green building is a structure that is environmentally responsible and resource-efficient throughout its life-cycle. These objectives expand and complement the classical building design concerns of economy, utility, durability, and comfort. Green buildings are designed to reduce the overall impact of the built environment on human health and the natural environment by:

• Efficiently using energy, water, and other resources 
• Protecting occupant health and improving employee productivity 
• Reducing waste, pollution and environment degradation

For example, green buildings may incorporate sustainable materials in their construction (e.g., reused, recycled-content, or made from renewable resources); create healthy indoor environments with minimal pollutants (e.g., reduced product emissions); and/or feature landscaping that reduces water usage (e.g., by using native plants that survive without extra watering).

Green paintings and coatings are a popular alternative to more traditional building materials, which may harbor harmful chemicals.

A green roof is a top of a building that is at least partially covered with vegetation to make it a garden or other natural, live landscape. Additional layers, such as a root barrier and drainage and irrigation systems may also be included.

Green roofs can be used in many applications, including industrial facilities, residences, offices, and other commercial property. In Europe, they are widely used for their stormwater management and energy savings potential, as well as their aesthetic benefits.
Green roofs are rooftops planted with vegetation. Intensive green roofs have thick layers of soil (6 to 12 inches, or more) that can support a broad variety of plant or even tree species. Extensive roofs are simpler green roofs with a soil layer of 6 inches or less to support turf, grass, or other ground cover.

Pervious pavement is a porous concrete that allows storm water to seep back into the ground.

Porous block pavement systems are prefabricated lattice structures made of concrete or plastic that are designed to support light traffic from cars and pedestrians, while allowing water to drain through. The blocks are filled with aggregate, or with soil planted with vegetation.

Smart growth is an urban planning and transportation theory that concentrates growth in the center of a city to avoid urban sprawl; and advocates compact, transit-oriented, walkable, bicycle-friendly land use, including neighborhood schools, complete streets, mixed-use development with a range of housing choices. Smart growth values long-range, regional considerations of sustainability over a short-term focus. Its goals are to achieve a unique sense of community and place; expand the range of transportation, employment, and housing choices; equitably distribute the costs and benefits of development; preserve and enhance natural and cultural resources; and promote public health.
