The Asia-Pacific Network of Early Career Professionals for Global Change Research (APN-ECAP) was launched in September 2023 to empower early career professionals (ECPs) across the Asia-Pacific region by enhancing their visibility, building capacity, and fostering cross-border collaboration in sustainability and global change research. Recognizing the persistent underrepresentation of early career voices in scientific and policy dialogues, APN-ECAP was designed as a dynamic platform to bridge the gap between emerging professionals, senior experts, and policymakers.

Over two years, the initiative engaged more than 500 professionals from 34 countries, convening seven regional workshops that served as hubs for knowledge exchange, peer learning, and leadership development. This exceeded the KPI of four major events, with each workshop surpassing the expected 50–60 participants per event, thus achieving and surpassing its Success Indicator (SI) for participation. These workshops emphasized inclusive representation, ensuring gender balance and targeted outreach to underrepresented subregions such as the Pacific.

Beyond events, APN-ECAP successfully developed several key resources, including the APN-ECAP Handbook (providing governance and participation guidelines) and a member database (registering 400+ professionals). Both met their KPIs for timely completion, with multiple revisions undertaken to ensure quality, and positive stakeholder feedback serving as the SI. A Communications Toolkit was also finalized, which contributed to a 25% increase in digital engagement, exceeding the KPI of a 20% growth in outreach.

Retention and engagement also met targets: 60% of members remained engaged across multiple activities, fulfilling the KPI and exceeding the SI of at least 40% retention. High-level visibility was achieved through representation at the APN Intergovernmental Meeting (IGM 2024), Conference of Youth (COY19), and UNFCCC COP29, which matched the KPI of securing participation in at least three international forums and met the SI of recognition by global stakeholders.

The initiative’s outcomes are evident in increased confidence and leadership among participants, strengthened regional collaboration, and heightened visibility of early career contributions to sustainability research. The impacts include the institutionalization of APN-ECAP within APN structures, the establishment of sustainable governance mechanisms, and a growing community of practice that extends beyond the project’s timeline. In conclusion, APN-ECAP has laid a strong foundation for empowering a new generation of sustainability leaders, consistently meeting or exceeding its KPIs and Success Indicators.
