What I want everyone at COP30 to know

When someone tells you they know how to curb emissions, the first question you should ask is: What’s your plan for cement and steel? They’re key to modern life, and they’re hard to decarbonize on a global scale because it’s so cheap to make them with fossil fuels.
Companies are beginning to roll out ways to either capture carbon from facilities that currently emit it, such as cement and steel plants, or to remove it directly from the air and store it permanently. If captured carbon becomes cheap enough, we could even use it to make things like sustainable aviation fuel. (Heirloom, Graphyte, MissionZero, Deep Sky).
