The United States and China are the world’s two largest economies, two largest consumers of energy, and two largest emitters of greenhouse gases. Together we account for about 40 percent of the world’s emissions.
We need to solve this problem together because neither one of us can solve it alone. Even if the United States somehow eliminated all of our domestic greenhouse gas emissions, it still wouldn’t be enough to counteract the carbon pollution coming from China and the rest of the world. Likewise, even if China went down to zero emissions, it wouldn’t make enough of a difference if the United States and the rest of the world didn’t change direction.
That’s the reality of what we’re up against. That’s why it matters that the world’s most consequential relationship has just produced something of great consequence in the fight against climate change.
Today, President Obama and Chinese President Xi Jinping are jointly announcing targets to reduce carbon emissions in the post-2020 period. By doing this – together, and well before the deadline established by the international community – we are encouraging other countries to put forward their own ambitious emissions reduction targets soon and to overcome traditional divisions so we can conclude a strong global climate agreement in 2015.
Our announcement can inject momentum into the global climate negotiations, which resume in less than three weeks in Lima, Peru, and culminate next year in Paris. The commitment of both presidents to take ambitious action in our own countries, and work closely to remove obstacles on the road to Paris, sends an important signal that we must get this agreement done, that we can get it done, and that we will get it done.
The Chinese targets also represent a major advance. For the first time China is announcing a peak year for its carbon emissions – around 2030 – along with a commitment to try to reach the peak earlier. That matters because over the past 15 years, China has accounted for roughly 60 percent of the growth in carbon dioxide emissions world-wide. We are confident that China can and will reach peak emissions before 2030, in light of President Xi’s commitments to restructure the economy, dramatically reduce air pollution and stimulate an energy revolution.
China is also announcing today that it would expand the share of total energy consumption coming from zero-emission sources (renewable and nuclear energy) to around 20 percent by 2030, sending a powerful signal to investors and energy markets around the world and helping accelerate the global transition to clean-energy economies. To meet its goal, China will need to deploy an additional 800 to 1,000 gigawatts of nuclear, wind, solar and other renewable generation capacity by 2030 – an enormous amount, about the same as all the coal-fired power plants in China today, and nearly as much as the total electricity generation capacity of the United States.
There is no question that all of us will need to do more to push toward the de-carbonization of the global economy. But in climate diplomacy, as in life, you have to start at the beginning, and this breakthrough marks a fresh beginning. Two countries regarded for 20 years as the leaders of opposing camps in climate negotiations – have come together to find common ground, determined to make lasting progress on an unprecedented global challenge. Let’s ensure that this is the first step toward a world that is more prosperous and more secure.
