EPA GHG emissions inventory tool charts cement plants’ CO2 tonnage

Source: U.S. Environmental Protection Agency; CP staff The EPA has released 2020 greenhouse gas (GHG) data collected under the Greenhouse Gas Reporting Program (GHGRP). Reported carbon dioxide and methane emissions from large industrial sources were approximately 9 percent lower than in 2019, reflecting both the economic slowdown due to the Covid-19 pandemic, and ongoing, long-term industry trends.

U.S. Geological Survey reveals limits of climate change projections

Sources: U.S. Geological Survey, Department of the Interior; CP staff A new report from the USGS—the indispensable source of portland cement, crushed stone and sand & gravel shipment data—stresses the need to factor uncertainties attending climate change predictions, especially as models link present greenhouse gas emission levels to earth temperature trajectories through the year 2100.

CalPortland documents glaring greenhouse gas accounting void

Paper cropped

In a new paper summarizing peer-reviewed scientific studies, CalPortland Co. staff cites the exclusion of a critical factor in global, national, and regional greenhouse gas accounting methods: Concrete buildings, pavements and structures are silently absorbing carbon dioxide from the atmosphere—to such an apparent degree that the built environment represents one of the world’s largest carbon storehouses.

Cement companies inventory low-carbon production methods per Paris Accord

Sources: World Business Council for Sustainable Development (WBCSD), Geneva; CP staff

A new report from WBCSD’s Cement Sustainability Initiative (CSI) focuses on technology availability and the need to scale up research and development that can help the cement industry mitigate greenhouse gas emissions. In light of the United Nations Framework Convention on Climate Change Paris Agreement’s entry into force, CSI effected an in-depth review of its original papers from 2009, when the sector issued the first ever low-carbon technology roadmap in partnership with the International Energy Agency (IEA).

Cement production undeniably minor in EPA greenhouse gas emissions census

Sources: U.S. Environmental Protection Agency; CP staff

U.S. portland cement production accounted for 2.3 percent of carbon dioxide-equivalent (CO2e) emissions in EPA Greenhouse Gas Reporting Program 2015 data. Modern kilns increasingly running on natural gas and other coal alternatives, coupled with limited offsetting import factors, appear to position the domestic cement industry favorably in a business often tagged as the source of 5 percent of global carbon dioxide emissions.
