Most importantly, the House of Representatives passed an energy and climate bill in June that would finally make clean energy the profitable kind of energy for American businesses and dramatically reduce greenhouse gas emissions.  One committee has already acted on this bill in the Senate and I look forward to engaging with others as we move forward.

最重要的是，国会众议院今年6月通过了一项能源和气候法案，终于有可能使清洁能源成为美国企业可使用的有益能源，同时也可以大幅度削减温室气体排放。国会参议院的一个委员会已着手审议这项议案，我期待着在向前推进的过程中同有关方面商谈。

Because no one nation can meet this challenge alone, the United States has also engaged more allies and partners in finding a solution than ever before.  In April, we convened the first of what have now been six meetings of the Major Economies Forum on Energy and Climate here in the United States.  In Trinidad, I proposed an Energy and Climate Partnership for the Americas.  We've worked through the World Bank to promote renewable energy projects and technologies in the developing world.  And we have put climate at the top of our diplomatic agenda when it comes to our relationships with countries as varied as China and Brazil; India and Mexico; from the continent of Africa to the continent of Europe.

由于任何一个国家都无法单独应对这一挑战，美国与比以往更多的盟友和伙伴接触，以寻找解决方案。今年4月，我们在美国举行了主要经济体能源和气候论坛第一次会议，该论坛到目前为止共举行了6次会议。在特立尼达，我提出了美洲国家能源和气候合作计划。我们通过世界银行在发展中国家推行可再生能源项目和技术。在同从中国到巴西，从印度到墨西哥，从非洲到欧洲的各个国家和地区的关系中，我们已将气候问题作为外交议程的首要议题。

Taken together, these steps represent a historic recognition on behalf of the American people and their government.  We understand the gravity of the climate threat.  We are determined to act.  And we will meet our responsibility to future generations.

上述举措多管齐下，体现出美国人民及其政府的一种历史认知。我们了解气候威胁的严重性。我们决心采取行动。我们将尽到对子孙后代的义务。

But though many of our nations have taken bold action and share in this determination, we did not come here to celebrate progress today.  We came because there's so much more progress to be made.  We came because there's so much more work to be done.

然而，尽管很多国家已经采取了有魄力的行动，同时在这个问题上也有共同的意志，但我们今天来到这里不是要庆贺成功。我们来到这里是因为还有许多进展有待实现。我们来到这里是因为还有很多工作有待完成。

It is work that will not be easy.  As we head towards Copenhagen, there should be no illusions that the hardest part of our journey is in front of us.  We seek sweeping but necessary change in the midst of a global recession, where every nation's most immediate priority is reviving their economy and putting their people back to work.  And so all of us will face doubts and difficulties in our own capitals as we try to reach a lasting solution to the climate challenge.

这方面的工作并不容易。随着哥本哈根会议的临近，我们最艰难的道路就在前方，对此不应该抱任何幻想。在全球陷入衰退之际，我们寻求全面但必要的变革。每一个国家最紧迫的任务是重振国民经济，让本国人民重回工作岗位。为此，在努力为应对气候变化寻求长远之计的同时，我们在各国首都会面临疑虑和困难。

But I'm here today to say that difficulty is no excuse for complacency.  Unease is no excuse for inaction.  And we must not allow the perfect to become the enemy of progress.  Each of us must do what we can when we can to grow our economies without endangering our planet -- and we must all do it together.  We must seize the opportunity to make Copenhagen a significant step forward in the global fight against climate change.

然而，今天我在这里表示，不能因为有困难而甘于现状。不能因为存在忧虑而无所作为。我们不能因为无法面面俱到而放弃取得进展的努力。我们每一个人都必须在可能的情况下全力以赴，在不危害我们这个星球的前提下促进我们的经济增长，我们必须共同努力。我们必须抓住时机，促使哥本哈根会议为全球抗击气候变化迈出重要的一大步。

We also cannot allow the old divisions that have characterized the climate debate for so many years to block our progress.  Yes, the developed nations that caused much of the damage to our climate over the last century still have a responsibility to lead -- and that includes the United States.  And we will continue to do so -- by investing in renewable energy and promoting greater efficiency and slashing our emissions to reach the targets we set for 2020 and our long-term goal for 2050.

我们也不能听任过去多年来在气候变化问题上反复出现的意见分歧阻挠我们取得进展。当然，一个世纪以来，曾给我们的气候造成诸多破坏的发达国家仍有义务发挥主导作用。我们将继续这么做——为可再生能源投资，提高能源效率，降低我们的排放量，实现我们为2020年制定的目标以及为2050年制定的长远目标。

But those rapidly growing developing nations that will produce nearly all the growth in global carbon emissions in the decades ahead must do their part, as well.  Some of these nations have already made great strides with the development and deployment of clean energy.  Still, they need to commit to strong measures at home and agree to stand behind those commitments just as the developed nations must stand behind their own.  We cannot meet this challenge unless all the largest emitters of greenhouse gas pollution act together.  There's no other way.

然而，在未来几十年内，增长迅速的发展中国家将几乎成为全球碳排放量所有增长部分的来源，这些国家也必须尽自己的一份力量。其中一些国家已经为发展和使用清洁能源迈出重要步伐。然而，这些国家仍需承诺在国内采取严厉的措施，同意坚持履行有关义务，如同发达国家也必须坚持履行自己的义务一样。所有的温室气体排放大国必须采取共同行动，否则我们就无法迎接这一挑战。我们别无选择。

We must also energize our efforts to put other developing nations -- especially the poorest and most vulnerable -- on a path to sustained growth.  These nations do not have the same resources to combat climate change as countries like the United States or China do, but they have the most immediate stake in a solution.  For these are the nations that are already living with the unfolding effects of a warming planet -- famine, drought, disappearing coastal villages, and the conflicts that arise from scarce resources.  Their future is no longer a choice between a growing economy and a cleaner planet, because their survival depends on both.  It will do little good to alleviate poverty if you can no longer harvest your crops or find drinkable water.

我们还必须加紧努力，使其他发展中国家，特别是最贫困和最孱弱的国家走上可持续增长的道路。这些国家不如美国或中国那样拥有抗击气候变化的同样资源，但是与问题的解决有着最直接的利害关系。因为这些国家已经承受了全球变暖造成的持续影响，如饥荒和旱灾；海岸村庄的消失以及因为资源稀缺导致的冲突。这些国家的未来不再是两者择其一，经济增长或者提高地球的清洁程度，因为其生存取决于两者的共同实现。人们如果不能再收获庄稼或得到饮水，对减轻贫困就毫无助益。

And that is why we have a responsibility to provide the financial and technical assistance needed to help these nations adapt to the impacts of climate change and pursue low-carbon development.

这就是为什么我们有责任提供必要的财务和技术援助，帮助这些国家适应气候变化造成的影响，并寻求低碳排放量的发展道路。

What we are seeking, after all, is not simply an agreement to limit greenhouse gas emissions.  We seek an agreement that will allow all nations to grow and raise living standards without endangering the planet.  By developing and disseminating clean technology and sharing our know-how, we can help developing nations leap-frog dirty energy technologies and reduce dangerous emissions.

我们正在寻求的目标毕竟不只是一项限制温室气体排放的协议。我们寻求达成的协议将使所有的国家在不危害地球的情况下实现增长和提高生活水平。通过发展和推广洁净技术并分享我们的专门知识，我们可帮助发展中国家跨跃肮脏能源技术的阶段，减少排放有害气体。
