The research, published in Science, found the oil operations are releasing vast quantities of compounds that can cause localized air pollution and form damaging particles that can travel across the continent.
Canada’s tar sands have gained infamy for being one of the world’s most polluting sources of oil, thanks to the large amounts of energy and water use required for their extraction. A new study says the operations are also emitting far higher levels of a range of air pollutants than previously known, with implications for communities living nearby and far downwind.

It’s been less than 20 years since baby food in plastic pouches first appeared on supermarket shelves. Since then, these convenient and popular “squeeze-and-suck” products have become the dominant packaging for baby food, transforming the way that millions of babies are fed around the world. But emerging evidence raises concerns that big food brands are feeding our children plastic pollution with unknown consequences, by selling baby food in flexible plastic packaging.
Testing commissioned by Greenpeace International in 2025 found plastic particles in the baby food products of two global consumer goods companies – Danone and Nestlé. The study suggests a link between the type of plastic the pouches are lined with – polyethylene – and some of the microplastics found. Tests also suggest a range of plastic-associated chemicals in the packaging and food of both products.

U.N. General Assembly Embraces Court Opinion That Says Nations Have a Legal Obligation to Take Climate Action
The U.S. was among eight countries that voted against endorsing the nonbinding ruling that said all nations must take steps to limit temperature rise to 1.5 degrees Celsius.
The United Nations General Assembly on Wednesday voted overwhelmingly in favor of a climate justice resolution championed by the small Pacific Island nation of Vanuatu. The resolution welcomes the historic advisory opinion on climate change issued by the International Court of Justice in July 2025 and calls upon U.N. member states to act upon the court’s unanimous guidance, which clarified that addressing the climate crisis is not optional but rather is a legal duty under multiple sources of international law.
