As climate reporting requirements continue to evolve in Singapore, many organisations are turning their attention beyond direct operations to understand emissions across their value chains. While Scope 1 and Scope 2 emissions remain the foundation of greenhouse gas (GHG) reporting, Scope 3 emissions often account for the largest share of a company's carbon footprint. Investors, customers, lenders and multinational corporations are increasingly seeking greater transparency on supply chain emissions as part of their sustainability commitments and net-zero strategies.  

For large companies subject to climate disclosure requirements, obtaining reliable Scope 3 data can be one of the most challenging aspects of ESG reporting. As a result, organisations are increasingly engaging suppliers, contractors, logistics providers and service partners to provide emissions information and demonstrate their own carbon management efforts. What was once viewed as a sustainability reporting exercise is now becoming a key business requirement across many industries.  

Suppliers Should Start Preparing Now

A growing number of businesses may assume that climate reporting obligations only apply to large listed companies. However, suppliers within the value chain are likely to receive increasing requests from their customers for energy consumption data, fuel usage records and Scope 1 and Scope 2 emissions information. Companies that are able to provide credible emissions data will be better positioned to support their customers' Scope 3 reporting requirements, strengthen business relationships and remain competitive in procurement and tender evaluations.

Organisations do not need to wait for mandatory reporting requirements before taking action. Establishing a GHG inventory, identifying major emission sources, improving data collection processes and setting reduction initiatives can provide significant advantages. As climate disclosure expectations continue to cascade through supply chains, companies that begin building carbon management capabilities today will be better prepared for future reporting requirements and emerging market opportunities.
