First, all major economies must put forward decisive national actions that will reduce their emissions, and begin to turn the corner on climate change. I'm pleased that many of us have already done so. Almost all the major economies have put forward legitimate targets, significant targets, ambitious targets. And I'm confident that America will fulfill the commitments that we have made: cutting our emissions in the range of 17 percent by 2020, and by more than 80 percent by 2050 in line with final legislation.

首先，所有的主要经济体必须提出明确的国家行动减少各自的排放量，着手在气候变化问题上开创新局面。令我高兴的是，我们已经有很多国家这样做了。几乎所有的主要经济体都已提出合理的目标，重大的目标，意义深远的目标。我坚信，美国将履行已经做出的承诺：到2020年减排17%，到2050年减排80%以上，使之符合最后通过的法案。

Second, we must have a mechanism to review whether we are keeping our commitments, and exchange this information in a transparent manner. These measures need not be intrusive, or infringe upon sovereignty. They must, however, ensure that an accord is credible, and that we're living up to our obligations. Without such accountability, any agreement would be empty words on a page.

第二，我们必须建立一种机制审查我们是否信守自己的承诺，并以透明的方式交流这方面的信息。这些措施不必具有干预性，无需涉及主权。但这些措施必须确保达成的协议言而有信，确保我们都在履行自己的义务。没有这种问责制度，任何协议都只是一纸空文。

I don't know how you have an international agreement where we all are not sharing information and ensuring that we are meeting our commitments. That doesn't make sense. It would be a hollow victory.

令我无法想象的是，对于达成的国际协议，各方可以不共享信息，也不保证履行各自的承诺。这种协议简直毫无意义，只能是徒有虚名。

Number three, we must have financing that helps developing countries adapt, particularly the least developed and most vulnerable countries to climate change. America will be a part of fast-start funding that will ramp up to $10 billion by 2012. And yesterday, Secretary Hillary Clinton, my Secretary of State, made it clear that we will engage in a global effort to mobilize $100 billion in financing by 2020, if - and only if - it is part of a broader accord that I have just described.

第三，我们必须筹集资金，帮助发展中国家适应气候变化，特别是那些最不发达和最容易受气候变化影响的国家。美国将参与一项快速启动融资项目。到2012年，该项目将筹集100亿美元。昨天，国务卿希拉里·克林顿（Hillary Clinton）明确表示，我们将参与全球行动，到2020年筹集1,000亿美元资金，前提是──只有在这个前提下──这项计划必须纳入我刚才谈到的更全面的协议。

Mitigation. Transparency. Financing. It's a clear formula - one that embraces the principle of common but differentiated responses and respective capabilities. And it adds up to a significant accord -- one that takes us farther than we have ever gone before as an international community.

减排。透明。融资。这是一个明确的方案──其原则是，共同应对，措施有别，各尽其能。所有这些构筑了一个重要的协议──可以让我们的国际社会取得前所未有的进展。

I just want to say to this plenary session that we are running short on time. And at this point, the question is whether we will move forward together or split apart, whether we prefer posturing to action. I'm sure that many consider this an imperfect framework that I just described. No country will get everything that it wants. There are those developing countries that want aid with no strings attached, and no obligations with respect to transparency. They think that the most advanced nations should pay a higher price; I understand that. There are those advanced nations who think that developing countries either cannot absorb this assistance, or that will not be held accountable effectively, and that the world's fastest-growing emitters should bear a greater share of the burden.

在这次全会上，我只想说，我们的时间所剩无几。在这个关头，问题在于我们是共同奋进，还是分道扬镳；我们是故作姿态，还是身体力行。我相信，许多人认为我刚才讲述的框架并不完美。任何国家都不可能得到自己希望的一切。有些发展中国家想得到援助，又不想满足任何条件，不想承担保持透明的义务。他们认为最发达的国家应该付出更高的代价；我理解这一点。有些发达国家则认为发展中国家或者没有能力利用这些援助，或者无法有效地承担责任，因此世界上增长最快的排放国应该承担更大的责任。

We know the fault lines because we've been imprisoned by them for years. These international discussions have essentially taken place now for almost two decades, and we have very little to show for it other than an increased acceleration of the climate change phenomenon. The time for talk is over. This is the bottom line: We can embrace this accord, take a substantial step forward, continue to refine it and build upon its foundation. We can do that, and everyone who is in this room will be part of a historic endeavor - one that makes life better for our children and our grandchildren.

我们知道存在这些分歧，因为我们已经多年受这些分歧的制约。这样的国际讨论到现在已经进行了几乎20年，除了气候变化现象的加速，我们没有取得什么结果。空谈该结束了。我们的底线是：我们接受这个协议，向前迈出实质性的一步，继续使之完善，在这个基础上再接再励。我们能够这样做。在座的每一位都能亲身参与这项前所未有的事业──为了改善我们子孙万代的生活。

Or we can choose delay, falling back into the same divisions that have stood in the way of action for years. And we will be back having the same stale arguments month after month, year after year, perhaps decade after decade, all while the danger of climate change grows until it is irreversible.

否则，我们只能继续拖延，保持多年来阻碍我们采取行动的分裂状态。月复一月，年复一年，或许再经过十几二十年，我们又将进行同样的老生常谈。与此同时气候变化的危险将发展到不可收拾的地步。

Ladies and gentlemen,

女士们，先生们，

There is no time to waste. America has made our choice. We have charted our course. We have made our commitments. We will do what we say. Now I believe it's the time for the nations and the people of the world to come together behind a common purpose.

时不我待。美国已经做出了我们的选择。我们已经规划了我们的路线。我们已经表达了我们的承诺。我们言出必行。我们认为，现在全世界各国和人民应该为了一个共同的目标齐心协力。

We are ready to get this done today - but there has to be movement on all sides to recognize that it is better for us to act than to talk; it's better for us to choose action over inaction; the future over the past - and with courage and faith, I believe that we can meet our responsibility to our people, and the future of our planet. Thank you very much. (Applause.)

我们准备今天完成这个工作──但所有各方必须行动起来，认识到言辞不如行动；无所作为不如有所行动；拘囿于过去不如着眼于未来──只要有勇气，只要有信心，我相信我们能够肩负起对人民，对我们星球未来的责任。非常感谢。（掌声）
