All eyes are on greener cements that reduce emissions. Any gain ripples across a very large global concrete industry. Global cement production was 4.1 billion tons in 2020, up from 1.39 billion tons 25 years earlier. China accounts for 2.2 billion tons of the total. India’s annual production is 340 million tons. There are more than 2,000 active cement plants around the world.
Global carbon removal goals are important yet daunting. One estimate suggests that “By 2050, the world must remove ten gigatons of CO2 per year.” That’s more than the current annual emissions of the United States. Excess carbon dioxide not only warms the atmosphere, it also increases ocean acidity. Atmospheric events grow more extreme, and marine ecosystems suffer.
A holistic approach to sustainable paving is ideal. Analysts increasingly look at a road’s entire lifecycle when calculating its carbon footprint. It is important to consider everything from the acquisition of aggregates and binders to the eventual recycling of road materials.
According to the U.S. Environmental Protection Agency (EPA), construction and demolition (C&D) waste totaled 600 million tons in 2018. Demolition accounted for about 90% of the total, while construction accounted for about 10%. 455 million tons of C&D debris went to “next use.” 145 million tons went to landfills.
Concrete offers an unbeatable combination of resiliency, versatility and price. It can be cast into endless shapes. It is integral to almost every new commercial and residential building. Those buildings will continue to proliferate worldwide. In fact, one estimate suggests the number of buildings worldwide doubling by 2060. That’s the equivalent of building another New York City every month — for the next 40 years!
Concrete remains the go-to material for many construction and infrastructure projects. Designers look to concrete’s resilience as extreme weather events proliferate.
Cement production has more than doubled since the turn of the century. It now stands at more than 4.1 billion tons. Future growth could increase production another billion tons per year by 2050.
