Sources: Global Steel Climate Council, Washington, D.C.; Nucor Corp., Charlotte, N.C.; CP staff A new Global Steel Climate Council standard offers a fair, effective, unbiased tool to measure greenhouse gas (GHG) emissions associated with long products used for concrete reinforcement or tensioning, plus structural steel members or shapes. Along with a protocol behind embodied carbon calculations, the 48-page Steel Climate…

Cement, steel production emissions add up to EPA rounding errors
The Environmental Protection Agency’s new Inventory of U.S. Greenhouse Gas Emissions and Sinks cites 5.586 billion metric tons (mt) of carbon dioxide equivalent (CO2e) emissions for 2021, a 6 percent increase over the prior year. The Inventory spans six economic sectors; the third largest, Industry, accounted for 24 percent, or 1.34 billion mt of CO2e in 2021. U.S. GREENHOUSE GAS…

Two of the principal organizations driving specifications and practices reflected in a building’s life cycle carbon metrics will review sentiments on their Proposed Standard 240P – Evaluating Greenhouse Gas (GHG) and Carbon Emissions in Building Design, Construction and Operation, posted at osr.ashrae.org. ASHRAE—synonymous with heating, ventilating, air conditioning and refrigeration standards—and the International Code Council present a methodology for quantifying…

In order to achieve the international objectives surrounding projected global warming trends through 2100, climate change observers contend, economies worldwide must reduce their greenhouse gas (GHG) emissions significantly in all sectors. Recognizing how emissions discipline applies to the construction industry, Germany’s Liebherr Group is working on new, efficient drive concepts for its concrete delivery and earthmoving equipment. The manufacturer enlisted…

The U.S. Department of Transportation has opened a public comment period for a Federal Highway Administration Notice of Proposed Rulemaking (NPRM) for states and municipalities to track and reduce greenhouse gas (GHG) emissions. The Infrastructure Investment and Jobs Act makes more than $27 billion available for state departments of transportation and metropolitan planning organizations to meet a declining GHG emissions…
Read MoreCement, concrete hold steady as minor GHG emissions data points
Technology Trends’ Craig Yeack breaks down cement savings and carbon dioxide emissions reduction math in a report on ready mixed production and the CarbonCure Technologies process. Outside of fly ash, admixtures and blended binders, CarbonCure’s dosing and injection technology is among the most widely adopted tools for lowering embodied carbon in finished concrete.
