Gov. Tom Wolf supports allowing his administration to formally study a petition that calls for Pennsylvania to impose a cap-and-trade program to make Pennsylvania carbon neutral by 2052.
Friday's statement by Wolf's office, however, says the Democrat isn't taking a position on the petition itself.
The roughly 400-page petition is scheduled for a preliminary vote April 16 before a 20-member environmental rulemaking board that includes several Wolf appointees.
A positive vote would allow Wolf's Department of Environmental Protection to study it and decide whether to recommend it for a rulemaking process, which requires another vote.
