As the UN Climate Change Conference in Tianjin comes to a close this week, the gridlock between the U.S. and China reached a fever pitch in the final negotiations before year-end talks in Cancun. While there has been a general consensus around the need for a "balanced package" (the conference catch phrase), the definition of this phrase varied between conference delegates. The U.S. wants a transparent deal that includes Measurement, Reporting and Verification (MRV), while China maintains that the U.S. and all developed nations must make binding commitments before it will join an international agreement. The two nations have emerged from talks as major players in the climate change impasse.

Despite U.S. criticism that China is not making serious commitments, hosting the current round of talks has given China a bigger platform to proclaim its impressive clean energy advancements. China has made tremendous progress in wind and solar energy, taking the lead on investment, use and production of renewable energy, and mobilizing to cut carbon intensity in half by 2020. The problem? China may prefer to make technological advancements and set emissions reduction targets on its own terms. China recognizes the opportunity of a green future, but doesn't necessarily feel the need to take on a leadership role in saving the climate.

China is a developing country, but it is also the world's greatest polluter. So while it stands to make the most progress, it also has the greatest responsibility. And so does the U.S. Touting global leadership status and producing the most emissions per capita also comes with great responsibility. According to Karl Burkart of the Global Campaign for Climate Action (GCCA) and Tck Tck Tck, U.S. pledges pale in comparison to China's:

• Per capita CO2 emissions 2008: U.S. 19 tons, China 5 tons
• Pledged emissions reductions: U.S. 0.8 gigatons, China 2.5 gigatons (UNFCCC)
• National gas standard:  U.S. 27 MPG, China 34 MPG
• Investment in clean energy 2009: U.S. $19 billion, China $35 billion

During a Climate Action Network (CAN) press conference on Day 1 at Tianjin, a Chinese Greenpeace activist may have said it best when she asked the question, "What kind of role does China want to play in [raising] the international ambition in the international process? Does China want to be part of the driving force, or get a free ride? It's impossible that an elephant as big as China will get a free ride."

Despite the recent slew of natural disasters and extreme weather plaguing various parts of the world, optimism about the impact of this winter's annual climate change conference is scarce. Set to take place in Cancun, Mexico this November 29 - December 10, 2010, the United Nations Climate Change Conference (COP 16) is evoking eye-rolls and sighs over what's expected to be yet another failed attempt at securing a global treaty on combating climate change. This apprehension is a stark contrast to the passionate buzz surrounding last year’s talks in Copenhagen. The vigor with which many world leaders, organizations, and activists attended the uniquely accessible event in Denmark was truly inspiring, and could have instilled hope into the hearts of even the most skeptical of commentators -- if not for the disappointing outcome. Ultimately, only five nations, including the U.S. and China, had any real say in the document that emerged from Copenhagen, which left many unsatisfied with the resulting level of ambition and jurisdiction.

While the U.S. Congress was unable to pass legislation prior to last year's talks (which would have added much-needed clout to President Obama's resolve on combating climate change), the U.S. did pledge to help raise $100 billion in global climate aid for vulnerable countries, as part of the non-legally binding Copenhagen Accord. To date, however, little progress has been made towards raising these funds.

The Accord, described as flimsy and inadequate, did not elaborate on the “how”, so much as the “what”, particularly regarding the $100 billion pledge, and accountability for industrial nations setting limits on emissions to prevent a global temperature rise of 2 degrees Celsius. Thus, the focus of this year's conference will likely be on financing: who will be responsible for what, and how funds will be raised and allocated.

But will the talks result in significant emissions cuts and an effective pay system to compensate low-emitting countries who are hit hardest by climate change? Or will they remain just that…more talks? It's time rich and high-emitting countries, particularly those who tout their leadership roles, walk the walk, too. Last year, an unprecedented number of world leaders came to the table, which proves the urgency of climate change has been acknowledged.  Perhaps now that business leaders are starting to direct the conversation towards the economic opportunities that climate change affords (a language those rich and high-emitting countries standing in the way can understand well), that urgency can finally translate into a binding agreement.

Or, perhaps China will save the day as they host their own summit in Tianjin this October. These final preparatory sessions leading up to the Cancun talks present a unique opportunity for China to step up as a leader in achieving a binding climate treaty. China is already the biggest global player in clean energy, but unfortunately, it’s also the largest carbon emitter.
