<onlyinclude>An '''environmental impact''' is defined as any change to the [[environment]], whether adverse or beneficial, resulting from a facility’s activities, products, or services.</onlyinclude><ref name=epa>US EPA.(August 7, 2015). ''Environmental Aspects'' [Online], Available: http://www.epa.gov/sectors/sectorinfo/sectorprofiles/shipbuilding/module_05.pdf</ref> In other words it is the effect that people's actions have on the environment. For example, when [[volatile organic compound]]s are released into the environment, the ''effect'' or ''impact'' is [[pollution]] in the form of [[smog]], in this case being negative. It can go the other way, as a person picking up litter can have a beneficial impact on the local environment.

===Negative Impacts===

The primary impacts of concern in an [[energy]] dependent society often come as a result of our energy use. Burning [[hydrocarbon]]s like [[coal]] and [[oil]] to provide us with useful energy results in the emission of [[carbon dioxide]] and other [[pollutant]]s. Other activities causing harm include improper waste disposal to bodies of water and soil, accidental spills of [[chemical]]s, increased demand for resources as populations increase (especially due to consumerism), and much more. The impacts that these have on the environment have become clear and include:

*[[Climate change]] including [[Global warming]]
*[[Acid rain]], [[photochemical smog]] and other forms of [[pollution]]
*[[Ocean acidification]]
*Displacement/extinction of wildlife
*Resource depletion - [[deforestation|forests]], water, food
*and more

There are many issues in the world that are causing one or more of these effects. The [[oil sands]], for instance, are of great concern to many these days as they essentially contribute to each of the above impacts, see [[environmental impacts of oil sands]].

For information on how the average person may be affecting the environment, visit [[CO2 footprint]] and [[anthropogenic ]]effects.

==Assessing Impacts==
The environmental impact a specific action may have can be analyzed using a '''[[life cycle assessment]]''', which is the process of observing a product from its "cradle to grave" and determining the impacts associated with it at each step.<ref name=lca>US Environmental Protection Agency. (May 25, 2015). ''Life Cycle Assessment'' [Online]. Available: http://www.epa.gov/nrmrl/std/lca/lca.html#define</ref> These methods are somewhat subjective and resource intensive.<ref name=epa/>

'''Emission inventories''' for example may quantify the [[emission]] of [[pollutant]]s, while '''risk assessments''' can analyze the effects these pollutants will have on the health of those within the environment.

'''Process hazard analysis''' involves identifying and assessing potential impacts of ''unplanned'' hazardous materials. A team may rank the possible hazards and focus on preventing those that can cause the most harm.
