Certification and Benchmarking

Certification and benchmarking are voluntary frameworks, using different forms of assessment and assurance, that give ports, investors, regulators and communities a common language for assessing environmental, social and governance (ESG) performance. They move ports from ad hoc or self-declared sustainability claims to auditable, comparable and continuously improving programs. For the Asian Development Bank (ADB) Green Ports Strategy, certification and benchmarking are cross cutting mechanisms that support every other Green Port Aspect: they operationalise policy commitments, provide the evidence base for sustainable finance, and drive continual improvement in practices such as emissions management, resource use, biodiversity protection, workforce standards and community engagement.

Globally, port sustainability certification has evolved from generic environmental management system (EMS) approaches, anchored in the International Organization for Standardization (ISO) 14001 Standard, toward sector specific schemes that reflect the distinctive operational, environmental and social risks of ports and harbors. Six programs are examined in this Aspect: (i) ISO Certified Management Systems (CMS), (ii) Green Marine and Green Marine Europe, (iii) EcoPorts and the ECO Sustainable Logistic Chain Foundation (ECOSLC), (iv) the APEC Port Services Network (APSN) GreenPort Award System (GPAS), (v) the GRESB Infrastructure Assessment, and (vi) the Marine Stewardship Council (MSC) Chain of Custody and Fisheries Standards. Together, these programs cover strategic governance, operational environmental performance, investor grade ESG disclosure and seafood supply chain traceability.

These six programs contribute to several United Nations Sustainable Development Goals (SDGs). Certification and benchmarking provide the verified performance data that makes progress toward Goal 9 (Industry, Innovation and Infrastructure) measurable, particularly under target 9.4, which commits member states to upgrade infrastructure and retrofit industries to make them sustainable by 2030. Certified management systems and sector schemes contribute to Goal 11 (Sustainable Cities and Communities) target 11.6 by reducing adverse per capita environmental impacts of cities, and to Goal 12 (Responsible Consumption and Production) targets 12.6 and 12.7, which call on companies to adopt sustainable practices and integrate sustainability information into reporting, and on public procurement practices to be sustainable. Climate linked benchmarks such as GRESB and energy management standards such as ISO 50001 can support national implementation of Goal 13 (Climate Action), which concerns integrating climate change measures into national policies, strategies and planning, while the MSC fisheries and chain of custody programs directly support Goal 14 (Life Below Water) targets 14.2 and 14.4 on sustainable management of marine ecosystems and the restoration of fish stocks.

For DMCs, certification and benchmarking are increasingly relevant because ports are facing converging pressures:

• Rising domestic climate disclosure rules.
• Increased expectations from key stakeholders including investors, customers, own workforce and communities.
• A need to ensure social licence to operate

Future approaches are expected to move in three directions.

1. First, integration: ports will combine management system certification (for example ISO 14001, ISO 45001 and ISO 50001), and independent verification of GHG inventories, with sector schemes such as Green Marine, EcoPorts or GPAS to reduce audit duplication and achieve recognition across ESG, climate and operational dimensions.
2. Second, digitalization: verified data from energy management, emissions inventories and environmental monitoring will flow directly into certification evidence packs, reducing the administrative burden and enabling near real time assurance.
3. Third, alignment with sustainable finance: certification outcomes are being mapped onto the ASEAN Taxonomy, the IFRS Sustainability Disclosure Standards S1 and S2, and the Global Reporting Initiative (GRI) framework, so that a single certification exercise supports investor reporting, regulator disclosure and community transparency.

Opportunities for adoption in DMCs include:

• the maturity of regional sector networking groups and industry forums, which can host peer learning and joint training on certification;
• the proliferation of donor supported technical assistance programs; and
• the growing supply of local third party verifiers.

Barriers include:

• the cost and complexity of initial certification for smaller public port authorities,
• limited availability of ASEAN language guidance for some schemes, and
• fragmented data systems that make evidence gathering time consuming.

Enabling conditions include government policy signals that recognize certified ports in concessioning and licensing processes, sustainable procurement frameworks that require certification from terminal operators and suppliers, and collaborative partnerships between port authorities, national regulators, development finance institutions and industry associations.

The practices that follow set out how each of the six frameworks contributes to green port outcomes, the evidence from global and Southeast Asian implementation, and the pathways for practical uptake across the region.
