Environmental aspects versus environmental impacts

Answer:
Look the example below.

At the maintenance warehouse, lubricating oils are handled to apply in preventive maintenance activities. Because people handle lubricating oils there is the possibility of spillages or leakages. If a spillage or leakage occurs, there is the possibility of contamination of soil or water.

The potential spillage or leakage is an environmental aspect, an element of an organization’s products, services and activities which can interact with the environment. Other examples of environmental aspects are, for example, discharges to water, emissions to air, use of natural resources and materials, or generation of wastes. Environmental impacts are the consequences of the environmental aspects.
At the example above, the environmental aspect is permanent but the environmental impact depends of the context, depends on the use of preventive and responsive measures.
