I pulled these off the end of an article in the Winnipeg Free Press, so I assume the numbers are all Canadian dollars.

What is a tree worth?
3 November 2005

According to a study for the City of North Vancouver:
  • Average annual benefits: $94 per tree per year
  • Annual costs for pruning, watering etc.: $18 in 2003
  • Benefit to cost ratio: more than five to one.

Breakdown of benefits, per tree
  • Reduced air-conditioning costs: $1
  • Sequestered carbon dioxide: $2
  • Reduced air pollution: no dollar value provided
  • Reduced storm runoff: $12
  • Property-value increase: $78
