Council leaders have decided to spend £20,000 assessing potential sites for new cemeteries in Oxford.
The money will be spent on environmental surveys of two or three possible new graveyards to find space for burials for the next 100 years.
Two of the city's four council-owned cemeteries, Headington and Rose Hill, are full and have been shut to new coffin burials for several years.
Botley and Wolvercote cemeteries have space for only another 10 years.
The last increase in burial space in Oxford was in 1932.
