Environmental policy

On the 22nd of March 2007, Picsearch implemented a new environmental policy making them the first carbon neutral search engine in the world. The Picsearch initiative was followed by promises from Yahoo in April and Google in June to go carbon neutral by the end of 2007.



The policy consists of four steps:
  1. Picsearch plants 1000 new trees for every gigawatt-hour consumed.
  2. Picsearch buys and holds in trust 2 acres (8,093.7 m²) of old growth forest for every gigawatt-hour consumed.
  3. Picsearch only uses electricity that is carbon free and follows the highest standard of production.
  4. Picsearch buys carbon credits equivalent to all the energy that Picsearch consumes.
