- Arizona Governor Janet Napolitano signed the "good" outdoor lighting bill into law on Monday, May 12, 2003. The law requires the full shielding of outdoor lighting fixtures for buildings and associated grounds and parking lots owned by the state or cities with a population over 50,000. It also requires energy efficiency for lighting systems for those facilities.
The bill, which will become effective 90 days after the current Regular Session ends, was the product of collaboration between astronomers, dark skies advocates, neighborhood and environmental groups, state agencies, and the League of Arizona Cities and Towns. Sen. Gabrielle Giffords was the lead sponsor and was instrumental in ushering the bill through the whole process. This state law is a major improvement over an earlier one passed nearly 20 years ago.
- In Calgary, Canada, they are now in the process of replacing all the existing streetlights with new EnviroSmart (full cut-off) streetlights.
The new lights will increase illumination levels on the ground below by so much
that they can half the wattage of the bulbs - and so the new light fittings will save the city $2 million a year! You might think that using lower powered bulbs would resulting in darker streets, but since the new light fittings ensure that 100% of the light produced is directed towards the streets and that no light is wasted, the night-time brightness of the streets will remain the same. The cost of replacing all these streetlights will be recouped within 6 years.
Also, the reduction in energy consumption will reduce carbon dioxide
emissions from coal fired power stations by over 300kg per
streetlight per year!. Take a

- The Czech republic recently passed a "Clean Atmosphere" law including the prevention of light pollution.
"In June 2002 the Czech Republic introduced the Protection of the
Atmosphere Act, defining light pollution as 'every form of artificial
light which is dispersed outside the areas it is dedicated to,
particularly if directed above the level of the horizon. Citizens are
now obliged to "take measures to prevent the occurrence of light
pollution in the air' or face fines of up to £2,800. Authorities are
now required to use fully shielded lights to control the spread of
light, and use flat rather than curved glass to prevent light
dispersing upwards and sideways. Advertising billboards will have to
be lit from above, with their lights pointing downwards. 'Fully
shielded light fixtures not only help preserve the beauty of the
starry sky, but they also illuminate more efficiently and allow people
to see better at night".
- Other countries and regions with legal controls on inefficient lighting (light pollution) include Slovenia, Liechtenstein, and Lombardy.
- Flagstaff in Arizona, USA, is the world's first international dark sky city, due to its exceptional commitment and success in making sure stars are visible in the skies above the city.
