API governance meets sustainability: Strategies for implementers

API governance plays a crucial role in building a sustainable IT ecosystem by reducing waste, emissions, and enhancing the resilience of systems, which is increasingly important as the IT sector is projected to consume 21% of global energy in the next decade. At the LEAP 2.0 API Governance Conference, experts highlighted the importance of integrating sustainability into API governance to drive efficiency and reduce environmental impact. Key areas of API governance include security, compliance, standardization, and lifecycle management, which, when combined with sustainable practices, can lower resource consumption, reduce waste, and enhance compliance with sustainability goals. Real-world examples demonstrate how optimizing API strategies, such as using pagination, GZIP compression, and caching, can significantly lower CO2 emissions and energy consumption. Tools like Gprofiler and Cloud Carbon Footprint can help measure and improve the sustainability impact of APIs, making API governance not only an ethical choice but also a strategic advantage for organizations seeking long-term business resilience.
