Cement and concrete production and use are major contributors to overall emissions in sectors that are hard to decarbonize. In contrast to previous assessments that have explored strategies to reduce emissions from cement and concrete, this project’s proposed framework will include technological detail and economic feedback to all activities globally and in particular regions. This framework for evaluating conventional and emerging technology solutions and their economic and environmental impacts will expand MIT tools and expertise to provide actionable guidance to both firms and policymakers on how best to reduce greenhouse gas emissions associated with cement and concrete production and use.
