The Company

Aeterni (latin): From the viewpoint of eternity

Aeterni.eco was established in October 2023 by Mr Wee Boon Siong who has more than 9 years of experience leading sustainability projects in sustainability reporting, carbon management and sustainable finance. Clients included big organisations in the regulatory and commercial sectors in Asia.

With Boon Siong’s track record as a sustainability pioneer, he is now building a company that distinguishes itself by offering in-depth, practical sustainability strategy advisory to help organisations truly embrace sustainability. 

In a short span of time, the company has helped companies in Singapore, Malaysia, and mainland China with their ESG journeys, enabling the achievement of important milestones.

The company now is the Approved EcoVadis Training Partner and a participant of the IFRS Sustainability Consultant Content Programme.

Core Value

We believe that we should effect positive change through not just our work, but also through our example.  

The company has made the following public commitments: 

  • We participate in the United Nations Global Compact (UNGC) and support the Ten Principles on human rights, labour, environment and anti-corruption (since 2024). 
  • We adopt the Tripartite Standards to be a fair and progressive employer (since 2024). 
  • We benchmark ourselves and continuously improve on our ESG policies, practices and performance (through annual EcoVadis assessment since 2024).
