Transcript for Obama: Paris Climate Deal 'Best Shot' to Save the Planet
Good afternoon error by. Today is a historic day in the fight to protect our planet for future generations. Ten months ago in Paris I said before the world that we needed a strong global agreement. To reduce carbon pollution and to set the world on a low carbon course. The result was the Paris agreement. Last month the United States and China the world's two largest economies and largest of matters. Formally join that agreement together. And today the world has officially crossed the threshold. For the Paris agreement to take effect. Today the world meets the moment and if we follow through on the commitments that this Paris agreement embodies. History may well judge it as a turning point for plant. Course it took a long title reach this day. One of the reasons I ran for this office was to make America a leader in this mission. And over the past eight years we've John done just that. In 2009 we salvage day cut chaotic climate summit in Copenhagen. Establishing the principle that all nations have a role to play in combating climate change. And at home we lead by example would historic investments in growing industries like wind and solar that created a steady stream of new jobs. We set the first ever nationwide standards to limit the amount of carbon pollution that power plants can dump into the air our children break. From the cars and trucks we drive into the homes and businesses in which we live and work. We've changed fundamentally the way we consume energy. I keep in mind the skeptics said these actions would kill jobs. And instead we saw. Even as we're bringing down these carbon levels the longest streak of job creation in American history. We drove economic output to new lives and we drove our carbon pollution to its lowest levels in two decades. We continued to lead by example would our historic joint announcement with China two years ago where we put forward even more ambitious climate targets. And that achievement encouraged dozens of other countries to set more ambitious climate targets of the wrong. And that in turn paved the way for our success in Paris. The idea that no nation. Not even one as powerful as ours can solve this challenge a law. All of us have to solve it together. Now the Paris agreement alone will not solve the climate crisis. Even if we meet every target. Embodied in the agreement will only get to park. Where we need to go. But make no mistake this agreement will help delay or avoid some of the worst consequences of climate change. It will help other nations ratchet down their dangerous carbon emissions over time. And set boulder targets as technology advances. All under a strong system of transparency that allows each nation to evaluate the progress of all other nations. And by sending a signal that this is going to be our future they clean energy future it opens up the floodgates for businesses and scientists and engineers. To unleash high tech low carbon investment and innovation at a scale the we've never seen before. So this gives us the best possible shot. To save the one planet we've got. I know diplomacy can be easy and progress on the world stage can sometimes be slow but together with steady persistent effort. With strong principled American leadership. Would optimism and faith and hope we're proving that it is possible. And I want to embarrass my senior advisor Brian Daze to standing right over there because he worked tirelessly to make this deal possible. He and John Kerry Gina McCarthy at the EPA everybody on their teams have done extraordinary job to get us this point and America should be as proud of of them as I am. Of them. I also want to thank the people are very nation that has moved quickly to bring the Paris agreement and to force. I encourage. Folks who have not yet. Submitted. There documentation to enter into this agreement to do so as soon as possible. And in the coming days let's help finish additional agreements to limit aviation emissions to phase down dangerous use. Haider for carpets. All of which will help build a world that is safer and more prosperous and more secure. And more free than the one. That was left for us. That's our most important mission to make sure kids or grandkids. Have at least as beautiful. Planet and hopefully more beautiful more in the we had. And today I'm a low more confident that we can get the job. So thank you very much of it.
