A specifically created section has been developed within the Honda UK site incorporating the do-it.org.uk search tool.
When people enter their postcode they will be directed to projects that could be both pertinent to their region and interests.
The partnership will be promoted via a 12-week regional press campaign and digital activity from 27 July.
It will go across 157 regional websites and newspapers, with microsites created by digital ad agency Collective.
Wieden & Kennedy produced the display ads for Honda, while Starcom handled the media.
The marketing push will aim to build on the launch of Honda Insight. The five door green hybrid is currently being promoted via a TV and cinema campaign titled “Everybody Wants To Be Good”.
Microsites will offer test drives of the Honda Insight, with £5 donated to local dealerships’ environmental charity of choice for each drive taken.
