Behind closed doors and downturned blinds, custom-built ovens with ambitious names like “Fearless” and “Intrepid” are helping to perfect a new technique of making silicon wafers, t… Read More

Carbon Pricing Helping Farmers Ease Methane Pollution

Carbon Pricing Helping Farmers Ease Methane Pollution

Biogas digesters are helping to protect the climate from methane, which is a far more potent greenhouse gas than carbon dioxide. As the world’s appetite for meat and dairy has grown, agriculture has become a bigger cause of global warming than deforestation, and that’s mostly because of the methane released by livestock farming.… Read More
