The article discusses the advancements in climate technologies in 2025, highlighting three key areas: green steel, cow burp remedies, and cleaner jet fuel. Green steel production is set to revolutionize the industry, with companies like Stegra using hydrogen from renewable sources to reduce emissions. The challenges lie in the high costs of building new steel plants and the need for customers willing to pay more for sustainable steel. Additionally, companies are developing remedies like Bovaer to cut methane emissions from cows, but they face hurdles in gaining acceptance from regulators, farmers, and consumers. In the aviation sector, cleaner jet fuel alternatives are emerging, made from waste products to reduce emissions. However, scaling up production to meet global demand remains a significant challenge. The year 2025 marks a crucial phase for climate technologies, with innovative solutions facing both obstacles and opportunities in combatting climate change.
