Gas stoves are a leading source of hazardous indoor air pollution, but they emit only a tiny share of the greenhouse gases that warm the climate. Why, then, have they assumed such a heated role in climate politics? This debate reignited on Jan. 9, 2023, when Richard Trumka Jr., a member of the U.S. Consumer Product Safety Commission, told Bloomberg News that the agency planned to consider regulating gas stoves due to concerns about their health effects. “Products that can’t be made safe can be banned,” he noted. Politicians reacted with overheated outrage, putting gas stove ownership on a par with the right to bear arms and religious freedom. CPSC Chair Alexander Hoehn-Saric tried to douse the uproar, stating that he was “not looking to ban gas stoves” and that his agency “has no proceeding to do so.” Neither does the Biden administration support a ban, a White House spokesperson said. Nevertheless, congressional Republicans raced to t...

Russia’s war on Ukraine has cast a shadow over this week’s meetings of world leaders at the G-20 summit in Bali and the United Nations climate change conference in Egypt. The war has dramatically disrupted energy markets the world over, leaving many countries vulnerable to price spikes amid supply shortages. Europe, worried about keeping the heat on through winter, is outbidding poor countries for natural gas, even paying premiums to reroute tanker ships after Russia cut off most of its usual natural gas supply. Some countries are restarting coal-fired power plants. Others are looking for ways to expand fossil fuel production, including new projects in Africa. These actions are a long way from the countries’ pledges just a year ago to rein in fossil fuels, and they’re likely to further increase greenhouse gas emissions, at least temporarily. But will the war and the economic turmoil prevent the world from meeting the Paris climate agreement’s lon...

The world could still, theoretically, meet its goal of keeping global warming under 1.5 degrees Celsius, a level many scientists consider a dangerous threshold. Realistically, that’s unlikely to happen. Part of the problem was evident at COP27, the United Nations climate conference in Egypt. While nations’ climate negotiators were successfully fighting to “keep 1.5 alive” as the global goal in the official agreement, reached Nov. 20, 2022, some of their countries were negotiating new fossil fuel deals, driven in part by the global energy crisis. Any expansion of fossil fuels – the primary driver of climate change – makes keeping warming under 1.5 C (2.7 Fahrenheit) compared to pre-industrial times much harder. Attempts at the climate talks to get all countries to agree to phase out coal, oil, natural gas and all fossil fuel subsidies failed. And countries have done little to strengthen their commitments to cut greenhouse gas emissions in the...

With the U.S. government promising over US$360 billion in clean energy incentives under the Inflation Reduction Act, energy companies are already lining up investments. It’s a huge opportunity, and analysts project that it could help slash U.S. greenhouse gas emissions by about 40% within the decade. But in conversations with energy industry leaders in recent months, we have heard that financial incentives alone aren’t enough to meet the nation’s goal of reaching net-zero emissions by 2050. In the view of some energy sector leaders, reaching net zero emissions will require more pressure from regulators and investors and accepting technologies that aren’t usually thought of as the best solutions to the climate crisis. ‘Net-zero,’ with natural gas In spring 2022, we facilitated a series of conversations at Penn State University around energy and climate with leaders at several major energy companies – including Shell USA, and electric u...

Cooks love their gadgets, from countertop slow cookers to instant-read thermometers. Now, there’s increasing interest in magnetic induction cooktops – surfaces that cook much faster than conventional stoves, without igniting a flame or heating an electric coil. Some of this attention is overdue: Induction has long been popular in Europe and Asia, and it is more energy-efficient than standard stoves. But recent studies have also raised concerns about indoor air emissions from gas stoves. Academic researchers and agencies such as the California Air Resources Board have reported that gas stoves can release hazardous air pollutants while they’re operating, and even when they’re turned off. A 2022 study by U.S. and Australian researchers estimates that nearly 13% of current childhood asthma cases in the U.S. are attributable to gas stove use. Dozens of U.S. cities have adopted or are considering regulations that bar natural gas hookups in new-construction h...
