The International Code Council, a leading global source of model codes or standards and building safety solutions, presents its “Code on a Mission” challenge with an eye to having over a third of the U.S. population covered by the 2021 International Energy Conservation Code (IECC) by the end of 2023. To make this a reality, ICC encourages the building industry…

Sources: Portland Cement Association, Washington, D.C.; CP staff True to a timeline announced in late 2020, the Portland Cement Association has adopted a Roadmap to Carbon Neutrality, billing it as an ambitious journey to low carbon dioxide emissions across the cement and concrete value chain by 2050. The document demonstrates how the U.S. cement and concrete industry, along with parties…
Read MoreGCC schedules Montana mill’s portland-limestone cement shift
Sources: GCC of America, Denver; CP staff The GCC Trident Plant near Three Forks, Mont. will fully convert to portland-limestone cement (PLC) production early next year. With capacity upward of 350,000 tons, the 110-year-old operation can potentially lower its net carbon dioxide emissions by 25,000 tons annually, based on the blending of fine limestone at 5 percent to 15 percent…
