EPA set to roll back rules that limit greenhouse gases and mercury from US power plants
WASHINGTON (AP) — The Environmental Protection Agency is poised to eliminate rules that limit greenhouse gas emissions from power plants fueled by coal and natural gas, part of a wide-ranging rollback of environmental regulations that Administrator Lee Zeldin has said would remove trillions of dollars in costs and 'unleash' American energy.
The EPA also plans to weaken a regulation that requires power plants to reduce emissions of mercury and other toxic pollutants that can harm brain development of young children and contribute to heart attacks and other health problems in adults.
The planned rollbacks, set to be announced Wednesday, are meant to fulfill President Donald Trump's repeated pledge to "unleash American energy" and make it more affordable for Americans to power their homes and operate businesses.
If approved and made final, the plans would reverse efforts by President Joe Biden's administration to address climate change and improve conditions in areas heavily burdened by industrial pollution, mostly in low-income and majority Black or Hispanic communities.
The power plant rules are among about 30 environmental regulations that Zeldin targeted in March when he announced what he called the 'most consequential day of deregulation in American history.' He said the actions would put a 'dagger through the heart of climate-change religion' and introduce a 'Golden Age' for the American economy.
Environmental groups vowed to challenge the rules in court.
'Power plants are among the largest sources of dangerous pollution in the nation. We have modern technologies that allow these plants to reduce pollution with available and cost-effective solutions,' said Vickie Patton, general counsel of the Environmental Defense Fund.
The clean-air standards targeted by the EPA under Trump, a Republican, "are protecting people across America today and will safeguard future generations,'' Patton said.
'Ignoring the immense harm to public health from power plant pollution is a clear violation of the law,'' added Manish Bapna, president and CEO of the Natural Resources Defense Council. 'Our lawyers will be watching closely, and if EPA finalizes a slapdash effort to repeal those rules, we'll see them in court.'
The EPA-targeted rules could prevent an estimated 30,000 deaths and save $275 billion each year they are in effect, according to an Associated Press examination that included the agency's own prior assessments and a wide range of other research.
It's by no means guaranteed that the rules will be entirely eliminated — they can't be changed without going through a federal rulemaking process that can take years and requires public comment and scientific justification.
Even a partial dismantling of the rules would mean more pollutants such as smog, mercury and lead — and especially more tiny airborne particles that can lodge in lungs and cause health problems, the AP analysis found. It would also mean higher emissions of the greenhouse gases driving Earth's warming to deadlier levels.
Biden, a Democrat, had made fighting climate change a hallmark of his presidency. Coal-fired power plants would be forced to capture smokestack emissions or shut down under a strict EPA rule issued last year. Then-EPA head Michael Regan said the power plant rules — the Biden administration's most ambitious effort to roll back planet-warming pollution from the power sector — would reduce pollution and improve public health while supporting a reliable, long-term supply of electricity.
The power sector is the nation's second-largest contributor to climate change, after transportation.
In its proposed regulation, the Trump EPA argues that carbon dioxide and other greenhouse gases from fossil fuel-fired power plants 'do not contribute significantly to dangerous pollution' or to climate change and therefore do not meet a threshold under the Clean Air Act for regulatory action.
A paper published earlier this year in the journal Science found the Biden-era rules could reduce U.S. power sector carbon emissions by 73% to 86% below 2005 levels by 2040, compared with a reduction of 60% to 83% without the rules.
'Our research shows that EPA's power plant rules make substantial strides to protect human health and the environment,'' said Aaron Bergman, a fellow at Resources for the Future, a nonprofit research institution and a co-author of the Science paper.
'Carbon emissions in the power sector drop at a faster rate with the (Biden-era) rules in place than without them,'' Bergman said in an email. 'And we also would have seen significant reductions in sulfur dioxide and nitrogen oxides, pollutants that harm human health."

Middle East tensions put investors on alert, weighing worst-case scenarios
By Saqib Iqbal Ahmed and Lewis Krauskopf NEW YORK (Reuters) -Investors are mulling a host of different market scenarios should the U.S. deepen its involvement in the Middle East conflict, with the potential for ripple effects if energy prices skyrocket. They have honed in on the evolving situation between Israel and Iran, which have exchanged missile strikes, and are closely monitoring whether the U.S. decides to join Israel in its bombing campaign. Potential scenarios could send inflation higher, dampening consumer confidence and lessening the chance of near-term interest rate cuts. This would likely cause an initial selloff in equities and possible safe-haven bid for the dollar. While U.S. crude prices have climbed some 10% over the past week, the S&P 500 has been little changed as of yet, following an initial drop when Israel launched its attacks. However, if attacks were to take out Iranian oil supply, "that's when the market is going to sit up and take notice," said Art Hogan, chief market strategist at B Riley Wealth. "If you get disruption to supply of oil product on the global marketplace, that is not reflected in today's WTI price and that is where things get negative," Hogan said. The White House said on Thursday President Donald Trump would decide on U.S. involvement in the conflict in the next two weeks. Analysts at Oxford Economics modeled three scenarios, ranging from a de-escalation in the conflict, a complete shutdown in Iranian production, and a closure of the Strait of Hormuz, "each with increasingly large impacts on global oil prices," the firm said in a note. In the most severe case, global oil prices jump to around $130 per barrel, driving U.S. inflation near 6% by the end of this year, Oxford said in the note. "Although the price shock inevitably dampens consumer spending because of the hit to real incomes, the scale of the rise in inflation and concerns about the potential for second-round inflation effects likely ruin any chance of rate cuts in the U.S. this year," Oxford said in the note. OIL IMPACT The biggest market impact from the escalating conflict has been restricted to oil, with oil prices soaring on worries that the Iran-Israel conflict could disrupt supplies. Brent crude futures have risen as much as 18% since June 10, hitting a near 5-month high of $79.04 on Thursday. The accompanying rise in investors' expectations for further near-term volatility in oil prices has outpaced the rise in volatility expectations for other major asset classes, including stocks and bonds. But other asset classes, including stocks, could still feel the knock-on effects of higher oil prices, especially if there is a larger surge in oil prices if the worst market fears of supply disruptions come true, analysts said. "Geopolitical tensions have been mostly ignored by equities, but they are being factored into oil," Citigroup analysts wrote in a note. "To us, the key for equities from here will come from energy commodity pricing," they said. STOCKS UNPERTURBED U.S. stocks have so far weathered rising Middle East tensions with little sign of panic. A more direct U.S. involvement in the conflict could, however, spook markets, investors said. Financial markets may be in for an initial selloff if the U.S. military attacks Iran, with economists warning that a dramatic rise in oil prices could damage a global economy already strained by Trump's tariffs. Still, any pullback in equities might be fleeting, history suggests. During past prominent instances of Middle East tensions coming to a boil, including the 2003 Iraq invasion and the 2019 attacks on Saudi oil facilities, stocks initially languished but soon recovered to trade higher in the months ahead. On average, the S&P 500 slipped 0.3% in the three weeks following the start of conflict, but was 2.3% higher on average two months following the conflict, according to data from Wedbush Securities and CapIQ Pro. DOLLAR WOES An escalation in the conflict could have mixed implications for the U.S. dollar, which has tumbled this year amid worries over diminished U.S. exceptionalism. In the event of U.S. direct engagement in the Iran-Israel War, the dollar could initially benefit from a safety bid, analysts said. "Traders are likely to worry more about the implicit erosion of the terms of trade for Europe, the UK, and Japan, rather than the economic shock to the US, a major oil producer," Thierry Wizman, Global FX & Rates Strategist at Macquarie Group, said in a note. But longer-term, the prospect of US-directed 'nation-building' would probably weaken the dollar, he said. "We recall that after the attacks of 9/11, and running through the decade-long US presence in Afghanistan and Iraq, the USD weakened," Wizman said.

This Dividend King Stands Out as a Long-Term Favorite
PepsiCo, Inc. (NASDAQ:PEP) is one of the best dividend stocks for a bear market. In uncertain times, investing in a dividend-paying stock that has seen a significant drop in price can be a smart move, provided the company's long-term fundamentals remain strong. A close up of a glass of a refreshing carbonated beverage illustrating the company's different beverages. PepsiCo, Inc. (NASDAQ:PEP) fits that description well. Despite a nearly 14% decline in its share price since the beginning of 2025, the company maintains its reputation as a Dividend King, with 53 consecutive years of dividend increases. The latest boost, which was a 5% rise, was announced alongside its Q4 2024 earnings. Such a consistent track record reflects a solid business strategy that performs well regardless of market conditions. PepsiCo, Inc. (NASDAQ:PEP) dividend history speaks to its disciplined management and operational strength. However, recent challenges have emerged. In April, the company lowered its annual profit outlook, citing rising production costs and weaker consumer spending, pressures linked to economic uncertainty stemming from wide-reaching tariffs introduced by President Donald Trump. Even so, analysts view these issues as temporary. Once the broader economic environment stabilizes, demand is expected to recover. PepsiCo, Inc. (NASDAQ:PEP) currently offers a quarterly dividend of $1.4225 per share and has a dividend yield of 4.4%, as of June 17. While we acknowledge the potential of PEP as an investment, we believe certain AI stocks offer greater upside potential and carry less downside risk. If you're looking for an extremely undervalued AI stock that also stands to benefit significantly from Trump-era tariffs and the onshoring trend, see our free report on the best short-term AI stock.

Taiwan central bank says US debt rising too fast may impact trust in Treasuries
TAIPEI (Reuters) -Taiwan's central bank governor warned on Saturday that rapidly rising U.S. debt could be "unfavourable" to the outlook for U.S. Treasuries and that U.S. President Donald Trump's trade policies have made investors cautious. Taiwan's $593 billion in foreign exchange reserves are more than 80% made up of U.S. Treasury bonds, according to the central bank, which said earlier this month that Treasuries were "sound" and still favoured by investors. It added there were no worries about the dollar's position as the leading international reserve currency. Governor Yang Chin-long, in a speech posted on the central bank's website, said Trump's repeated criticisms of the U.S. Federal Reserve's monetary policy have caused concerns about its independence. "In addition, Trump 2.0's trade policy has made investors hesitant about holding U.S. Treasury bonds; Trump's budget, the 'One Big Beautiful Bill Act,' may cause U.S. debt to expand too quickly, which is unfavourable to the outlook for U.S. sovereign debt," he said. "All of these have had a significant impact on the international monetary system centred on the U.S. dollar and based on U.S. creditworthiness." Trump's sweeping tax-cut and spending bill is the centerpiece of his domestic agenda. The bill would lead to a larger-than-expected $2.8 trillion increase in the federal deficit over the decade, despite a boost to U.S. economic output, the nonpartisan Congressional Budget Office projected on Tuesday. Trump, in his first few weeks in office, also announced sweeping tariffs on a broad swathe of countries and trading partners, including Taiwan, only to pause them for 90 days in April to allow for talks to take place. Yang said Trump had been hoping the tariffs could resolve the U.S. trade deficit. "However, the tariff policy not only fails to solve the structural problems, it will also impact the U.S. economy, and threaten to further affect the outlook for global trade and the economy."
