The Vietnamese government has declared its commitment to achieving net-zero greenhouse gas (GHG) emissions by 2050, leading to a rapidly growing need for understanding GHG emissions and developing and managing sustainability information locally. However, many local companies and companies operating in Vietnam face challenges in calculating GHG emissions, disclosing sustainability information, and complying with various regulations.

Against this backdrop, KLINOVA JSC, the newly partnered company, is a consulting firm specializing in green growth and sustainable development. It boasts extensive experience in areas such as sustainable finance, energy transition, carbon credits, GHG inventory, life cycle assessment (LCA), and ESG report development, with a strong understanding of the Vietnamese market and local implementation capabilities.

This partnership will combine Zeroboard's "Zeroboard" solution with KLINOVA JSC's knowledge and expertise to provide more effective support. Specifically, both companies will work closely together, from understanding local needs to supporting the introduction and operation of "Zeroboard," providing information sharing and learning opportunities for client companies, and offering information on calculation, regulations, and disclosure. We will also actively work to promote understanding of sustainability initiatives across the entire Vietnamese market.
