UNISONScotland visitors will notice today that we "turned the lights out" on the UNISONScotland homepage as a gesture to raise awareness of a worldwide energy conservation effort called Earth Hour.

Ok, it saves no energy; modern displays use the same amount of power regardless of what they display. However, you can do something to reduce the energy consumption of your home PC by joining the Climate Savers Computing Initiative. On Saturday, March 28, 2009, Earth Hour invites people around the world to turn off their lights for one hour – from 8:30pm to 9:30pm in their local time zone.

On this day, cities around the world will hold events to acknowledge their commitment to energy conservation.

UNISON supports the Earth Hour campaign, and we have darkened our homepage today to help spread awareness of what we hope will be a highly successful global event. How green can you be?

The UK's carbon footprint is over 500 million tonnes of CO2 per year. Individuals account for 45% of this. Calculate your carbon footprint and find out how you can reduce it by turning off unused lights and other carbon-reducing actions.
