Scope and Leonard Cheshire are urging supporters to lobby Anne McGuire, the minister for disabled people, to create a fund for access to volunteering.
The fund would pay for things, such as transport costs and special computer equipment, that would allow more disabled people to volunteer.
The charities argue that making volunteer environments friendly to disabled people wouldn't cost much - paying their taxi fares, for example.
They also claim that volunteering would help young disabled people build experience for their CVs, which could help them gain work.
"An access to volunteering fund would enable disabled people to engage in their local communities, which would help both individual and community," said a spokesman for Scope.
The charities have also produced a guide designed to help volunteer managers make their opportunities more accessible to young disabled people.
