Emersons Green was until 1927 a hamlet in the civil parish of Mangotsfield. From 1927 to 2015, it was in the civil parish of
Mangotsfield Rural. The parish was renamed Emersons Green in 2015 and enlarged by the addition of areas of the civil parishes of
Pucklechurch and
Westerleigh, taking in the housing development at Lyde Green and the science park. The parish council elected to be known as Emersons Green Town Council. The parish has four wards: Badminton, Blackhorse and Pomphrey wards each elect three councillors, and Emersons Green ward – which also covers Lyde Green – elects seven councillors. For elections to
South Gloucestershire Council, the Emersons Green ward has almost the same boundaries as the parish and elects three councillors. For Westminster elections, the parish is part of the
Filton and Bradley Stoke constituency. == Lyde Green ==
