Concrete production adds 8% of worldwide greenhouse gases, and demand continues to rise as populations and incomes grow. But some commonly mentioned strategies to scale down the industry’s global GHG emissions could, under some scenarios, increase local air pollution and associated health damages, based on research from the University of California, Davis.
For the research, printed today within the journal Nature Climate Change, scientists quantified the costs of climate change impacts and death and illness from air pollution. They discovered that concrete production causes about $335 billion per year in damages, a significant fraction of the business worth.
The scientists also, in contrast, several GHG-reduction methods to determine that are most likely to decrease global emissions and domestic air pollution-related to concrete production.
They discovered that quite a lot of out there methods may, together, reduce climate and well-being injury costs by 44%.
Among the many best methods embrace utilizing cleaner-burning kiln gas, extra renewable vitality, and changing a portion of the cement used in manufacturing with lower-carbon materials.
While carbon capture and storage technologies may scale down GHG emissions from concrete manufacturing by as much as 28%, the study found it may improve human well-being impacts from air pollution, except the technology itself is powered by clean energy. It is also not at the moment widely implementable.
