A CAR share scheme is being expanded after scoring success in its first few months.
More than 180 people have signed up since the launch.
Now businesses are being invited to join in as well.
Birstall Shopping Park and furniture chain Ikea are the first to encourage their staff to take part.
Ikea is giving away free bulbs to its workers who fill in the registration form.
The car share scheme was set up by Kirklees Council and national company Liftshare.
People wanting to use the system can access the website at www.carsharekirklees. com and register their journey details for free.
The system then tells them if anyone else is going in the same direction and encourages them to make contact through a secure email connection.
They can then arrange to share both the journey and the cost of travel.
The local scheme can also link to the national database which has 133,579 members.
It is estimated they save an average of £1,091 per year by sharing their journeys.
Kirklees Council Cabinet member Clr Martyn Bolt said: "As well as reducing travel costs, the scheme will encourage more efficient use of vehicles and reduce congestion and pollution."
Denis Copeland, centre manager of Birstall Shopping Park, said: "This is a great opportunity to encourage the staff to share cars.
"Not only is it in their interest to be more environmentally friendly and save fuel costs as well, but it is also in the interest of customers who shop on site."
