World Ecology Bureau

The World Ecology Bureau (WEB for short) was a global environmental organisation based in England, headed by Sir Colin Thackeray.

History
In the 1970s, when a scientific expedition in Antarctica informed WEB of their discovery of a Krynoid pod, Sir Colin summoned the Fourth Doctor to investigate. WEB employee Richard Dunbar sold information about the pod to Harrison Chase. (TV: The Seeds of Doom)

WEB continued to maintain files on the Doctor and in the 21st century contacted UNIT to gain access to the space-time telegraph to contact the Eighth Doctor for assistance in their investigation of Alex Marlowe and his research into Krynoids. (AUDIO: Hothouse)

In 2020, Dorothy McShane was supposed to got to a meeting with WEB, but convinced her business manager to go instead. (PROSE: At Childhood's End)

Behind the scenes

 * According to The Terrestrial Index, WEB was formed at the same time as UNIT and for the same reasons, but this is never indicated on-screen.
 * The Seeds of Doom remains to date WEB's only on-screen appearance.
