Joe Biden’s withdrawal from the 2024 presidential race — bowing to weeks of pressure after a disastrous June debate and polls that showed worsening odds against his Republican rival, Donald Trump — upends the contest only weeks before Democrats meet in Chicago to confirm their nominee. Biden, 81, is the first sitting US president not to seek reelection for decades. He’s been a uniquely consequential leader on climate, most notably by signing the 2022 Inflation Reduction Act, the largest investment in reducing emissions and boosting clean energy in the nation’s history. Biden pledged that the US would halve its emissions by 2030. He rejoined the Paris Agreement after Trump pulled the US out of it and created the role of special presidential envoy for climate, among other actions. That presents a stark contrast to Trump, 78, who has called...

In June 2019, then-presidential candidate Joe Biden tweeted: “Trump doesn’t get the basics. He thinks his tariffs are being paid by China. Any freshman econ student could tell you that the American people are paying his tariffs.” Fast-forward five years to May 2024, and President Biden has announced a hike in tariffs on a variety of Chinese imports, including a 100% tariff that would significantly increase the price of Chinese-made electric vehicles. For a nation committed to reducing greenhouse gas emissions, efforts by the U.S. to block low-cost EVs might seem counterproductive. At a price of around US$12,000, Chinese automaker BYD’s Seagull electric car could quickly expand EV sales if it landed at that price in the U.S., where the cheapest new electric cars cost nearly three times more. As an expert in global supply chains, however, I believe the Biden tariffs can succeed in giving the U.S. EV industry room to grow. Without the tariffs, U.S. auto sa...

The United States is producing more oil and natural gas today than ever before, and far more than any other country. So, what roles did the Trump-Pence and Biden-Harris administrations play in this surge? The answer might surprise you, given the way each has talked publicly about fossil fuels: former President Donald Trump embracing them, and President Joe Biden and Vice President Kamala Harris focusing on reducing fossil fuel use to fight climate change. Under each of the three most recent presidencies, Republican and Democratic alike, U.S. oil and gas production was higher at the end of the administration’s term than at the beginning. That production has both pros and cons. Together, oil and gas account for nearly three-quarters of U.S. energy consumption. Producing oil and gas in the U.S. provides energy security, and high production generally keeps prices down. Burning oil and gas, however, releases carbon dioxide into the air, contributing to climate change. And nat...

Although Vice President Kamala Harris touts clean energy and Donald Trump makes misleading assertions and false claims about it, neither candidate has set forth a comprehensive energy plan. Even if they do, a gridlocked Congress would be unlikely to pass it. Instead, the next president’s greatest influence on clean energy will come through their handling of legislation and regulations put in place since 2021 under the Biden-Harris administration. As an environmental engineer who studies energy and climate change, I expect that Harris, who has strongly supported these policies, would follow through on them, while Trump’s record as president suggests that he would try to roll them back. Trade policies toward China, the leading producer of clean energy technologies, will also be key. Donald Trump and Kamala Harris discuss clean energy policy during their presidential campaign debate on Sept. 10, 2024. Legislation and regulations Th...

As the U.S. prepares for another Trump administration, one area unambiguously in the incoming president’s crosshairs is climate policy. Although he has not released an official climate agenda, Donald Trump’s playbook from his last stint in the Oval Office and his frequent complaints about clean energy offer some clues to what’s ahead. Exiting the Paris climate agreement Less than six months into his first presidency, Trump in 2017 formally announced that he was withdrawing the United States from the Paris climate accord – the 2015 international agreement signed by nearly every country as a pledge to work toward keeping rising temperatures and other impacts of climate change in check. This time, a greater but underappreciated risk is that Trump will not stop at the Paris Agreement. Trump attends a session of the United Nations Climate Action Summit in 2019. When he announced he would pull the U.S. out of the Pari...
