| 摘要： | The most widely used material in the world-concrete-has the unique capability to both meet infrastructure demands and sustainability requirements at scale. This new challenge comes as the annual costs for extreme weather are now reaching hundreds of billions of dollars, but concrete has long proven its worth as a durable and practical material. Resistant against extreme temperatures and weather, concrete is virtually maintenance-free. Cement production is an energyintensive process, but there are proven solutions across the value chain to reduce the CO_2 emissions from cement manufacturing. The Portland Cement Association (PCA), representing the majority of U.S. cement production capacity and manufacturers, released its Roadmap to Carbon Neutrality in late 2021. The ambitious, far-reaching strategy has a goal of reaching carbon neutrality throughout the cement-concrete-construction value chain by 2050. In this roadmap, PCA charts a course to reduce CO_2 emissions and reach net-zero while still meeting the increasing demand for safe, sustainable, resilient infrastructure that withstands the fury of climate-related weather events. |
