The Local Government Association and Volunteering England are encouraging councils to make more use of volunteering services.
The two bodies are working together to increase the number of unemployed people who use volunteering to improve their skills, and to support volunteer projects that improve local communities and environments.
The two bodies will hold a conference for local authority officers and councillors on 29 April, featuring examples of good practice from the voluntary and public sectors.
"Councils are interested in supporting people who are vulnerable," said Sally Cooke, third sector policy consultant at the LGA. "They're also interested in helping people who are disadvantaged in the labour market, and they can do these things through volunteering."
