Practices Collection Showcase: Innovative Application of Carbon Label and Carbon Reduction Integrated Supply Chain Management (Vol. 1) Upgrading Thailand’s Green Procurement Database for Carbon-Label Integration

Lately, the report of Practices Collection-Innovative Application on Carbon Label and Carbon Reduction Integrated Supply Chain Management was jointly released within the collaboration between International Green Purchasing Network (IGPN) and the One Planet Network Sustainable Public Procurement (SPP) Programme, which was produced by IGPN Secretariat-China Environmental United Certification Center (CEC).
The Practices Collection brings together innovative supply chain practices from seven organizations across four countries: China, the United States, Thailand, and the Netherland. By summarizing practical experience and demonstrating phased achievements, the Practices Collection effectively enhances supplier capacity, promotes the adoption of carbon labelling, and stimulates market and supply-side demand for sustainable products and services.

Practice #1｜Upgrading Thailand’s Green Procurement Database for Carbon-Label Integration

Theme: Public institute/corporation supplier management and carbon label; Digitization and carbon label

Core Content: Digital empowerment for green public procurement
This practice focus on applying a digital public procurement data system, which is automatically connected to the eco-label and carbon label databases maintained by relevant certification agencies. This enables the tracking of the carbon emission reduction benefits brought about by public procurement, thereby facilitating public institutions to make informed and climate-friendly procurement decisions and to monitor the progress in real time.
It is essential to be highlighted that the practice has strengthened the management of procurement data related to the environment and carbon performance, establishing a connection between eco-labels, carbon labels and the procurement database, thereby improving procurement efficiency.。

Innovation in Supply chain Management
This practice demonstrates how technological integration and data-driven decision-making can facilitate innovation in supply chain management：
-Technological integration: Establish an API integration between the procurement center, the eco-labeling and the carbon label certification agency databases to achieve synchronization, real-time updates, and interconnection of low-carbon data;
-Data-driven decision-making: Pilot testing in public procurement agency, procurement performance reports has been established, automating carbon impact tracking and enabling data-driven decisions on a scale, enables the automatic tracking of carbon emission reduction information, laying the foundation for the wide application of data-based decision-making methods and the promotion of the green and low-carbon procurement system.
The upgrade practice of Thailand's green procurement database, starting from the public procurement scenario, has achieved initial success through data integration, system integration, and model innovation, in realizing the upgrade of procurement management, carbon emission reduction control, and supply chain governance. This provides a reference for various public institutions and enterprises to build a low-carbon procurement system, improve the application of carbon labels, and optimize carbon emission reduction management in the supply chain.
