DETROIT, April 9 (Reuters) – A group of activist investors including the state of Connecticut on Wednesday dropped a campaign targeting Ford Motor Co (F.N) after the No. 2 U.S. automaker detailed plans for cutting greenhouse gas emissions over the next 12 years.

Ford’s action made it the first U.S. automaker to spell out how it intends to cut by 30 percent the greenhouse gas emissions from new vehicles it sells by 2020, according to the activist investor groups that pushed it to make the pledge.
