The United Nations Climate Change Conference (COP25) currently taking place in Madrid is supposed to prepare the ground for more ambitious national climate commitments. Nowhere is this more important than in the country where national leadership on climate change is least likely: the United States.
But a new report should give the world hope that it’s not too late to keep the US on a path in line with global aspirations to avoid the most catastrophic effects of climate change. This will require continued leadership from US states, cities, and businesses that are already stepping up, combined with reinvigorated action from the federal government.
The US is the world’s second-largest emitter of greenhouse gases, and was the largest overall emitter for decades. Although China surpassed it in 2006, America’s cumulative emissions remain unmatched. And yet, far from leading the way on climate action, the US under President Donald Trump’s administration has rolled back many federal climate and environmental rules and formally indicated its intention to withdraw from the 2015 Paris climate agreement by late next year.
Fortunately, the rest of the US is not following Trump’s lead. Across the country, a massive coalition of states, cities, businesses, universities, and others have declared that “We Are Still In.” Despite the federal government’s official withdrawal from the Paris agreement, they will take the necessary steps to fulfil America’s climate commitments.
This is no pie-in-the-sky declaration. The coalition’s more than 3,800 participants (and counting) include states, cities, and counties that account for 65% of the US population, nearly 70% of US GDP – equivalent to an economy larger than China’s – and over half of US emissions. For example, 145 US cities have committed to 100% clean electricity, and six have already achieved it.
But serious questions remain. How much progress can this coalition make to reduce emissions without the federal government’s support? And how much better would the situation be if the US administration and Congress recommit to climate action? These are the questions that America’s Pledge, a Bloomberg Philanthropies initiative, has been working to answer over the last year.
The conclusions are both reassuring and daunting. According to the initiative’s just-released third report, “Accelerating America’s Pledge” (produced in collaboration with the Rocky Mountain Institute, the University of Maryland, and the World Resources Institute), stronger action by states, cities, and businesses could reduce US greenhouse-gas emissions by 37% (compared to 2005 levels) by 2030.
In other words, even without the federal government, the US can drastically reduce emissions, improve air quality, and stimulate broad-based economic gains. Success would require an expanded coalition of non-federal actors to move quickly and ambitiously to transform energy and transportation systems, including by building on the innovative measures that US states, cities, and businesses are already taking.
The impact of such a movement promises to extend beyond US borders, with bottom-up commitments in the country leveraged to increase climate ambition around the world. This is already starting to happen. For example, Alliances for Climate Action connects cities, states, the private sector, investors, universities, and civil-society organisations in Argentina, Japan, Mexico, South Africa, the US, and Vietnam, so that they can work with one another and with their national governments to spur climate action.
But the role of the national government remains important. Despite the potential of bottom-up climate leadership, the fact remains that the results are much better when combined with top-down co-ordination and oversight. The America’s Pledge report shows that aggressive US federal re-engagement on climate action – in the form of a comprehensive “all-in” strategy – could reduce emissions by 49% by 2030, putting the country on track to reach net-zero emissions by mid-century.
So, despite three years of federal indifference, all hope for effective climate action in the US is not lost. But we cannot afford to rest easy. The needed transformation will require broad citizen mobilisation, increased energy productivity, disruptive innovation, updated market structures, and forward-thinking investment. The US Congress and executive branch must take aggressive, quick action, placing climate change and the associated economic transformation at the top of the policy agenda.
The rewards would be tremendous. Beyond environmental benefits, the changes outlined in the America’s Pledge report, if designed well and implemented efficiently, could boost prosperity, lower consumer costs, and improve public health. By 2030, the economic transformation could deliver equal or better performance in electricity, vehicles, and buildings compared to fossil-fuel technologies – and at a lower price.
For example, it is already cheaper to shut down coal-fired power plants and replace them with wind and solar than it is to keep the plants online. In addition, the transition will create new job opportunities and the careers of the future, including in renewable energy, electric vehicle manufacturing, and sustainable forestry (among others). Recent analysis by the Global Commission on the Economy and Climate shows that smart climate action can create global economic gains of $26tn by 2030, as well as generating 65mn jobs.
Non-federal US actors have laid a strong foundation for climate action, and they continue to drive progress. But to achieve the necessary transformation as quickly as required, more elected US officials and national leaders will need to step up. – Project Syndicate
