Tech Growth Too Slow to Decarbonize Steel, Cement by 2050

  • Deployment of infrastructure for CO2 transport and storage, renewable electricity, and green hydrogen is insufficient to meet zero-emission targets under the Paris Agreement
  • Anticipated infrastructure deployment is significantly lower than actual deployment, leading to a gap in meeting carbon capture and storage targets
  • Current construction plans will not meet demand for steel and cement in line with carbon budgets based on the Paris Agreement
  • The study suggests the need for a 60% reduction in material use in construction and a 40% reduction in manufacturing to meet Paris-compliant budgets
  • Slow Tech Growth Hinders Efforts to Decarbonize Steel and Cement by 2050

    Steel and cement are essential materials for any society, but their production comes with a significant carbon footprint. However, new research shows that the current rate of deployment of infrastructure for CO2 transport and storage, renewable electricity, and green hydrogen is insufficient to meet zero-emission targets under the Paris Agreement.

    Anticipated vs. Actual Infrastructure Deployment

    A study led by Dr. Takuma Watari reveals a significant gap between anticipated and actual infrastructure deployment. Scenarios made by the International Energy Agency (IEA) in 2010 estimated a much higher capture and storage of CO2 from the steel and cement industries than what has actually been achieved, casting doubt on the ability to meet future targets.

    Challenges in Meeting Carbon Budgets

    The study also highlights the challenges in meeting carbon budgets based on the Paris Agreement. Current construction plans are not expected to meet the demand for steel and cement, necessitating a reduction in material use in construction and manufacturing to meet Paris-compliant budgets.
