Dynamic lighting systems make positive contributions to the environment in two powerful ways.

• The primary area of impact of this technology consists of mitigating the Greenhouse gas emissions (GHG), air polluting emissions including criteria air contaminants (CAC), and all other types of emissions associated with electricity generation using fossil fuels--primarily coal.
• Fluorescent tube disposal and ballast replacement need not be as frequent because of the extension of their operating life as a result of dimming and time management.

A significant amount of conserved energy, particularly during peak demand periods, results in a substantial reduction in the use of coal and associated GHG and CAC emissions. During the next ten years, if 10% of the retrofit and new installation markets in Canada and the United States use completely dimmable systems, we will reduce the need for 4,000 MW installed capacity relying on fossil fuel. This will result in a reduction of about 35Mt of GHG emission and other types of emissions. Approximately, this was the amount that Canada needed to reduce its total GHG emission in 1990 (about 36 MT of CO2 equivalent) under the Kyoto Protocol.
