In general, stormwater management activities and systems do not entail significant energy consumption or greenhouse gas emissions. However, using alternative stormwater management approaches has several benefits that pertain to climate change.

Alternative designs that mimic natural hydrological patterns reduce the overall impacts of traditional stormwater infrastructure. Besides protecting water quality in streams, rivers and estuaries, the alternative systems can result in beautifully landscaped areas or wildlife habitat. These areas enhance communities and support climate-protection strategies such as creation of green neighborhoods.
