Overview

Sustainable construction refers to the practice of building structures that minimize environmental impact, from design to demolition. This approach considers factors such as energy efficiency, water conservation, and waste reduction. According to the United Nations, the built environment is responsible for nearly 40% of global greenhouse gas emissions, making sustainable construction a critical component of climate change mitigation. The use of sustainable materials, such as reclaimed wood and low-carbon concrete, is on the rise, with companies like Cross-Laminated Timber (CLT) manufacturer, Katerra, leading the charge. However, the high upfront costs of sustainable materials and the lack of standardization in the industry pose significant challenges. As the world's population is projected to reach 9.7 billion by 2050, the need for sustainable construction practices will only continue to grow, with the global market expected to reach $10.3 trillion by 2025, according to a report by MarketsandMarkets.
