Donald Trump has long expressed doubt about the reality of climate change, calling it a "hoax" and criticizing environmental policies as an "ecological scam." His administration advocated for increased fossil fuel production, encapsulated by his slogan "Drill, baby, drill." However, the military conflict in Iran, which began under his leadership, has led to a notable reduction in carbon emissions, the largest in years. The war has created a prolonged oil and gas crisis, according to The Washington Post. The International Energy Agency (IEA), a global organization that provides energy statistics and analysis, reported a significant drop in carbon emissions. Emissions in 2026 are expected to be much lower than those in 2025, a decline not seen since the height of the Covid-19 pandemic in 2020. At that time, crude oil demand was 91 million barrels per day, compared to 102 million currently. The IEA analysis suggests that global demand for oil could decrease by 2.5% this year compared to 2025, which would be equivalent to removing the emissions of 42 million gasoline-powered cars from the atmosphere. A key question is whether this drop in oil and gas consumption will continue. Some experts predict that once the conflict ends, demand in the Middle East will return to pre-war levels. However, half of the world's carbon emissions are now attributed to just 32 major companies. Many economists, though, believe the recent market disruptions could lead to a lasting shift toward sustainable energy. Evidence includes the growing number of people switching to electric vehicles and the expansion of wind, solar, and nuclear energy projects. Homeowners are also replacing oil-fired heating systems with more efficient heat pumps. Emerging technologies, such as geothermal energy, are becoming more profitable, leading to increased investments in green energy infrastructure. Pavel Molchanov, an investment strategy analyst at Raymond James, notes that the IEA expects oil demand in 2027 to be only slightly higher than before the conflict, with some of the decline being permanent. It is unlikely that Donald Trump foresaw that his actions in Iran would lead to a significant drop in carbon emissions, a development that may ultimately benefit the global climate.
