Sources: The Climate Group, London; CP staff A global survey assesses construction and other industry stakeholder perspectives on two principal load-bearing materials produced at lower than normal levels of greenhouse gas emissions. Among respondents, 40 percent say they would be willing to pay a premium for emissions reductions of 25 percent or higher for concrete, while 47 percent would be…

CarbonBuilt eyes new concrete plant deployments with Meta support
Sources: CarbonBuilt, Los Angeles; CP staff Dovetailing their participation in “Leadership and Green Growth,” a Climate Week New York City panel, officials of CarbonBuilt and Facebook host Meta Platforms announced a plan to broaden adoption of the former company’s Reversa binder and process technology, where carbon dioxide is sequestered in concrete and mix designs require lower than normal volumes of…
Read MoreEPA publishes Buy Clean construction materials label program primers
The Environmental Protection Agency Office of Chemical Safety and Pollution Prevention has outlined an implementation plan for a program and publicly accessible registry providing data on greenhouse gas emissions attending principal building and infrastructure project inputs. The EPA Label Program for Low Embodied Carbon Construction Materials will define parameters and thresholds informing the White House Federal Buy Clean Initiative, which…
Read MorePaving the Way: Carbon Sequestration in Concrete to Mitigate Environmental Impact
Concrete, the most extensively used manmade material worldwide, contributes an estimated 8 percent of anthropogenic greenhouse gas emissions. With annual volume running 30 gigatonnes, concrete consumption is over 3.5 tonnes of per person. The majority of the GHG emissions (88.5 percent) emanate from production of portland cement, the essential ingredient in concrete. Carbon sequestration in concrete presents a promising avenue…

Sources: Rimere, Newport Beach, Calif.; CP staff Rimere, a developer of processes extracting high value compounds from natural gas, has entered a codevelopment agreement with California neighbor Holliday Rock, a key player in ready mixed, aggregate and asphalt production, to quantify the potential of graphene to improve concrete strength, elasticity, shrinkage, shielding and durability. Composed of a single layer of…
Read MoreGHG Inventory shows cement plant CO2 emissions’ positive trend
The latest Environmental Protection Agency Inventory of U.S. Greenhouse Gas Emissions and Sinks cites 2022 GHG loads of 5.489 billion metric tons of carbon dioxide equivalent, a 1.3 percent increase from the prior year. The GHG Inventory factors emissions of CO2, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride and nitrogen trifluoride—all pegged for their global warming potential when released to…
Read MoreReduced Carbon Concrete Consortium assists states’ FHWA grant pursuits
The American Concrete Pavement Association, Iowa State University-hosted National Concrete Pavement Technology Center and allies have formed the Reduced Carbon Concrete Consortium (RC3) to assist state departments of transportation and other qualifying entities eyeing grants under the just-announced Federal Highway Administration Low-Carbon Transportation Materials (LCTM) program. RC3 will provide DOTs technical assistance and facilitate contractor preparedness with critical next steps…

The U.S. Environmental Protection Agency claims avoidance of 1 billion tons of greenhouse gas emissions and $13 billion in net society benefits attributable to GHG Emissions Standards for Heavy-Duty Vehicles – Phase 3. If upheld after near-certain legal challenges, new thresholds in the final rule, measured against Phase 2 targets, will equate to CO2 emissions reduction levels of a) 8-40…
