The 1980s saw far-reaching changes in the tactics and influence of the British environmental lobby, and in the place of the lobby in the public policy process. At the beginning of the decade, the lobby was already large and well supported. Through its contacts with ministers, peers, backbenchers and civil servants, and through its productive relations with the media, it had been able to help bring about significant policy changes, including amendments to many key pieces of legislation. To all intents and purposes, the lobby constituted the only significant opposition to government policy on the environment.
