Senator James Inhofe responded positively to reports of voluntary initiatives by private businesses to reduce greenhouse gas emissions. He said these initiatives demonstrate that government controls on carbon dioxide emissions are unnecessary and support the Bush Administration's rejection of mandatory schemes like the Kyoto Protocol. However, Inhofe expressed concern that these private initiatives could pave the way for future government regulation of carbon dioxide. He said Congress should not interpret these initiatives as an invitation to impose mandatory caps or carbon trading markets.
