22 Carbon credits
22 3 purchased project based carbon credits
Yes. (Please answer the following questions) 

 
indicate credits meet following commitments
Delta and Northwest have made contributions to The Conservation Fund and The Nature Conservancy, respectively, that have been used to offset passenger travel by planting trees. In October 2007 Delta, via its Delta Force for Global Good Foundation, made a grant to The Conservation Fund to offset a portion of the estimated carbon dioxide emissions from passengers flying the Delta Mainline Shuttle on Earth Day 2007. The Fund allocated $220,000 to offset these emissions by planting 49,064 trees. The remaining grant dollars were used to plant a tree for each of Delta’s 47,161 employees. Delta also made a grant to The Conservation Fund as part of the Earth Day 2008 pledge to match customer donations. Northwest made a 3 year, $1 million philanthropic contribution to The Nature Conservancy as a founding member.
