On April 19, Reps. Dingell and Boucher published the responses of industry groups, non-governmental organizations (NGOs), and labor unions to potential climate change legislation. The energy industry and environmental organizations had been asked to respond to the implications of a cap-and-trade system and other methods to reduce greenhouse gas emissions.
Dingell commented that the input from over 70 organizations has underlined "the challenge we have before us in balancing our environmental and economic needs." Dingell added that the committee will take into consideration the variety of concerns that have been expressed and that each sector of the economy will be asked to contribute to a solution. Boucher stated that the biggest challenge before the committee is to "write a mandatory greenhouse gas control measure with economy-wide application that does not dislocate any economic sector."
