Bus operator Transdev - which runs services across Keighley, Skipton and Ilkley - is making a 10p donation from every customer journey this Sunday to the Ukraine Humanitarian Fund.
Each bus across the fleet for its services from the Keighley depot - as well as others across Yorkshire, Lancashire and Greater Manchester - will also wear a Ukranian flag shaped in a heart as a public show of support for the country.
Transdev CEO Alex Hornby said: “Like everyone, we have all been saddened by the appalling events in Ukraine and the dreadful impact on this has had on people who have had to flee the country.
“All of us at Transdev at our locations right across the north of England felt compelled to show our support and we hoped the donation from our fares this weekend will go some way in giving the right kind of help to those who need it.
“We are proud to employ a number of Ukrainian families as part of our own team here in the north and give our full support to international Transdev colleagues aiding the humanitarian effort elsewhere in Europe.”
