Green Steel and Cement Fall Far Short of Climate Targets as Leaders Sound the Alarm

A Climate Week NYC panel laid bare the gulf between green steel and cement production and what the planet actually needs, with experts from four continents converging on one message: government procurement specifications — not new technology — are the fastest lever available to close the gap.

• Green steel pipeline delivers at most 50 million tonnes annually — climate targets demand 150 million
• Only $20 billion of the $200–$500 billion needed for steel decarbonization has been committed
• New York State sets emissions limits on concrete by compressive strength under Buy Clean law
• Kenya reaches 85% blended cement market share after replacing 1966 colonial building code
• Global coalition launches Blend Better Cement campaign to scale proven 50% emissions cuts
• Responsible Steel builds interoperability bridges between competing national green steel standards in China, Germany, India and Korea

Why it matters: Steel and concrete together account for roughly 15% of global CO₂ emissions — and they are the physical backbone of the clean energy transition itself. Without a shared vocabulary for what "green" means, the trillions of dollars needed to decarbonize these industries cannot flow.
