Czech Republic

The Czech Republic is the first country in the world to pass a countrywide light pollution degree

Since 2002 a degree for protecting the night environment demands the shielding of lamppost lights and other public illumination to control the spread of light, and use flat rather than curved-belly glass to prevent light shooting upwards and sideways. The regulations  follow closely the Lombardy law, background can be found at http://www.astro.cz/darksky
