About this hub

What it is

A single reference point for sustainability reporting in Singapore. It brings together three things that normally live in different places: the local regulatory obligations, the international frameworks those obligations map onto, and the emission factors you need to actually produce a number.

How it stays current

The hub checks the issuing bodies directly — NEA, MSE, NCCS, EMA, SGX, ACRA, MAS, BCA and Enterprise Singapore locally, plus GRI, the IFRS Foundation, ISO, the GHG Protocol and others internationally. Nothing here is copied from a secondary aggregator or a news roundup.

Four habits keep it both prompt and well-mannered towards the sites it reads:

• Each source on its own rhythm. Every publisher has its own due time rather than everything being checked on one clock, so checking often costs almost nothing.
• It learns each publisher's pace. A body that has just published is checked more often; one that has gone quiet is checked less, down to a floor. Active publishers surface quickly without anyone adjusting a setting.
• It never re-reads what has not changed. The hub remembers what it last saw from each source and asks only for what is new, so an unchanged publisher costs a single, near-empty exchange.
• It repairs itself. Regulators restructure their sites regularly. When a source stops responding the hub goes looking for its new location rather than quietly going stale — which is how most link collections rot.

Adding a publisher takes one field: someone responsible for the site pastes in a URL, and the hub works out for itself how to follow that site, accepting it only if real, dated items come back.

What gets kept

Government channels carry plenty that has nothing to do with sustainability, so every item is scored for relevance before it is kept, tagged by topic and framework, and checked against what is already here. The same press release put out through three different channels collapses to one entry.

What this is not

It is not legal, accounting or assurance advice, and it is not a substitute for the primary sources. The calculator is a screening tool: a reported inventory needs proper organisational and operational boundaries, complete activity data, and — for Scope 2 — both location-based and market-based figures. Every figure here links to the publication it came from. Check it before you rely on it.
