In the face of the pressing challenges posed by climate change, the engineering industry has a critical role to play in driving sustainable practices and reducing carbon emissions.
According to a report by Statista on annual global carbon dioxide emissions from 1940 to 2023, global carbon dioxide emissions from fossil fuels and industry totaled 37.15 billion metric tons (GtCO₂) in 2022. Emissions are projected to have risen by 1.1 percent in 2023 to reach a record high of 37.55 GtCO₂. Since 1990, global CO₂ emissions have increased by more than 60 percent.
The biggest contributor to global greenhouse gas (GHG) emissions is China, followed by the United States. China has become the world’s largest emitter due to rapid economic growth and industrialization in recent decades, leading to emissions soaring by more than 400 percent since 1990. In contrast, U.S. CO₂ emissions have fallen by 2.6 percent, yet the United States remains the biggest carbon polluter in history.
An outbreak of COVID-19 caused global CO₂ emissions to plummet by 5.5 percent in 2020 due to lockdowns and other restrictions. However, this wasn’t the only time when a major global event caused emissions reductions. For example, the global recession resulted in CO₂ levels falling by almost two percent in 2009, while the recession in the early 1980s also had a notable impact on emissions. On a percentage basis, the largest annual reduction occurred at the end of the Second World War in 1945, when emissions decreased by 17 percent.
One innovative approach that is gaining traction is the integration of artificial intelligence (AI) and generative design into the engineering workflow. Sustainability is no longer a choice but a necessity, and with this imperative, modern engineering projects are increasingly turning to artificial intelligence (AI) for innovative solutions. AI-powered sustainable design transforms how engineers conceptualize, execute, and maintain projects, allowing for smarter, greener infrastructure and minimizing environmental impact.
In this post, we will explore how AI-driven technologies contribute to reducing the carbon footprint in engineering projects and shaping a more sustainable future.
Understanding the Carbon Footprint in Engineering
Before diving into AI’s role in sustainability, it’s essential to grasp what a carbon footprint entails within engineering projects. The carbon footprint refers to the total amount of greenhouse gases (GHGs) emitted during a project’s lifecycle, from materials extraction and transportation to construction and operation. The building and construction industry is responsible for nearly 40% of global carbon emissions, making it a significant contributor to climate change.
