The Roy Castle Lung Cancer Foundation is hoping to encourage clean air in business environments through an awards scheme set up last week.
The National Clean Air Award will be given to employers committed to implementing effective workplace no-smoking policies.
The charity is offering two awards. Gold will be given to completely smoke-free premises, and silver to companies with an exterior smoking shelter or a fully enclosed interior smoking room.
Award holders will receive a certificate, be entered into an online directory of smoke-free places and can apply for a plaque to demonstrate their commitment to their employees' and customers' health.
"Employers have a legal responsibility to protect the health of their employees," said Mike Unger, the charity's chief executive. "We hope this award will help them fulfil that responsibility."
The award will also be given out by franchises such as Smoke Free Liverpool, an alliance of charities, councils and companies already working towards a smoke-free Liverpool. It has been endorsed by the Chartered Institute of Environmental Health and the National Asthma Campaign.
