To help our efforts, American Humane commissioned a study comparing the cost of EBI and gas chambers that proves EBI is less costly to communities. Using data from an animal sheltering organization, the study showed that the cost to use carbon monoxide poisoning is $4.98 per animal. The cost to use EBI, however, is only $2.29 per animal.

This cost analysis matrix uses actual 2007 cost and animal data from a municipal animal control agency in North Carolina.
