Think you know where everyone stands on climate change legislation? Test your knowledge of where everyone stands on the proposal to impose tariffs on imports from countries that the United States says aren't limiting their own carbon emissions. Such provisions were included in the House-approved Waxman-Markey bill and may be included in a Senate bill as well.

Question 1: When asked about the "border measures" in the Waxman-Markey bill, who said: "At a time when the economy worldwide is still deep in recession and we've seen a significant drop in global trade, I think we have to be very careful about sending any protectionist signals"?

A: U.S. Trade Representative Ron Kirk
B: Congressman David Dreier
C: President Barack Obama

Answer: C — President Barack Obama, quoted in The New York Times, June 29, 2009.

Question 2: Who said "the enacted bill must be consistent with our international obligations and an open and integrated global economic system"?

A: Peterson Institute for International Economics
B: World Trade Organization
C: White House Statement of Administration Policy

Answer: C — Statement of Administration Policy on H.R. 2454, the American Clean Energy and Security Act of 2009, issued by the White House on June 26, 2009.

Question 3: Who said applying "unilateral carbon tariffs to force other nations to address climate change … is extremely unlikely to be effective and may simply elicit retaliatory tariffs… The United States must comply with its obligations as a member of the World Trade Organization (WTO) as it considers measures to reduce greenhouse gas emissions"?

A: American Enterprise Institute
B: U.S. Chamber of Commerce
C: Democratic Leadership Council

Answer: B — U.S. Chamber of Commerce International Policy Backgrounder — The Nexus of Climate Change and Trade: Don't Break the Rules, May 2009.

The bottom line? It's easy to misunderstand -- or misrepresent -- the positions of different people and organizations in this complex debate, even when there's ample common ground, such as on the importance of upholding international trade rules when considering climate change legislation.
