Further progress could allow us to provide cheap, clean energy for everyone. The prices of solar, wind, and batteries have plummeted in recent decades, increasingly undercutting the cost of fossil fuel alternatives. Technological advances could allow us to do both. If we want to reduce these emissions, we need to transform our energy systems, industries, and food systems.Īt the same time, we need to tackle energy poverty, low standards of living, and poor nutrition, which all remain enormous problems for billions of people. 1ĬO 2 and other greenhouse gases like methane and nitrous oxide are emitted when we burn fossil fuels, produce materials such as steel, cement, and plastics, and grow the food we eat. Human emissions of greenhouse gases are the primary driver of climate change today.
