Benefits of a Sustainability-focused Digital Twin

Digital twins in manufacturing significantly enhance sustainability by enabling companies to integrate eco-friendly practices across various operational aspects. Here are some of the key benefits:

Cost Savings

Manufacturers using digital twins can achieve substantial cost reductions by optimizing energy use and reducing waste. For instance, a report from EY highlights that digital twins can decrease greenhouse gas emissions and the carbon footprint of buildings by up to 50%, alongside cost savings of up to 35% ²⁸.

Operational Efficiency

Digital twins contribute to operational efficiency by allowing manufacturers to simulate new product designs and manufacturing configurations before actual implementation. This preemptive modeling helps in fine-tuning energy consumption patterns and significantly lowering Scope 1, 2, and 3 emissions ²⁸.

Enhanced Decision Making

The strategic use of digital twins aids in predictive insights, guiding resource allocation and investment strategies for sustainable growth. Additionally, they provide real-time tracking of carbon footprints across the supply chain, ensuring transparency and aiding in the decision-making process for a sustainable design-to-delivery journey ²⁸.

By leveraging these benefits, manufacturers not only comply with environmental regulations but also enhance their brand reputation and stakeholder engagement through demonstrable sustainability efforts.

Challenges and Solutions in Implementing Digital Twin
