Mr. LIEBERMAN. Mr. President, I rise today to join my friend and colleague, Senator McCain, to introduce the first ever comprehensive legislation to limit the emissions of greenhouse gases in the United States. Today we take the first step up a long mountain road, a road that will culminate with this country taking credible action to address the global problems of our warming planet. The rest of the world is now taking on the challenge this problem presents. The United States, as the world’s largest emitter of the gases and the home of the world’s strongest economy, must not have its head in the clouds. https://www.congress.gov/congressional-record/2003/01/09/senate-section/article/S153-1
