Although carbon sequestration programs for non-industrial forestland owners in Massachusetts are being developed, very little is known about the program attributes of importance to different types of landowners or the likelihood that landowners will participate in any given program. This study estimates the probability that Massachusetts landowners will participate in several carbon offset programs using data from a survey of 3000 Massachusetts forestland owners. Results from an ordered logit discrete choice model suggest that the likelihood of enrollment in most programs is quite low. Landowners are clearly motivated by economic factors, but other aspects of carbon sequestration may also be important in their decision making.
