Written by our assessment team: what the criteria mean in practice, the evidence that works, and where learners get caught out.
What this unit is really about
Unit 522 has one clear practical deliverable: criterion 3.1 requires you to undertake a sustainability audit. Everything in LO3 follows from it — potential improvements identified, then recommendations made. So the audit is the unit, and it needs to be a real exercise with findings rather than a description of your organisation's sustainability policy.
The framing is the three pillars — environmental, social and economic — and criterion 1.2 asks you to examine their interdependences. That word is the analytical requirement, and it is where most portfolios go thin.
The evidence that works
| Learning outcome | Evidence that works well |
|---|
| LO1 — principles | The principles of sustainability, an examination of the interdependences between the three pillars, and a review of the impact of current sustainability legislation on organisations |
| LO2 — frameworks | An analysis of how a sustainability framework affects decision-making, how organisations align practices with frameworks, and how frameworks prepare organisations for emerging issues |
| LO3 — recommend improvements | The audit itself, potential improvements identified, and recommendations |
A workable audit scope for one area: energy use, waste and recycling, water, travel and fleet, procurement and supply chain, materials and packaging, digital footprint, plus the social dimensions — employment practice, local recruitment, community impact, supplier labour standards. Score each on current position, impact and improvement opportunity, and record how you established each figure.
Interdependence, done properly
Criterion 1.2 wants the tensions, not a diagram of three overlapping circles. Real interdependences a manager can evidence:
- The cheapest supplier is often the least environmentally sound, so environmental gains carry an economic cost that has to be funded
- Reducing headcount cuts emissions per unit of output and damages the social pillar
- Local sourcing cuts transport emissions and usually raises unit cost
- Home working cuts commuting emissions and shifts energy use to domestic heating, while weakening team cohesion
- Long-life products reduce waste and reduce replacement revenue
Naming a tension your organisation actually faces, and how it resolved it, is worth more than any amount of definition.
Frameworks and legislation, accurately
For LO2, the frameworks worth naming are the ones organisations actually align to: the UN Sustainable Development Goals, the Greenhouse Gas Protocol with its scope 1, 2 and 3 emissions, ISO 14001 environmental management systems, ESG reporting expectations, science-based targets, and B Corp certification for those pursuing it. Scope 3 is the honest analytical point: most organisations' emissions sit in their supply chain, which is exactly the part they control least.
For criterion 1.3, keep the legislative review current and relevant to Great Britain: the Climate Change Act 2008 as amended, which sets the net zero by 2050 target; Streamlined Energy and Carbon Reporting (SECR) for large companies; the Environment Act 2021; extended producer responsibility and packaging rules; waste duty of care; and the Modern Slavery Act 2015 transparency requirement for the social pillar. Say which of these actually applies to your organisation and which does not — a review that lists everything is weaker than one that reasons about thresholds.
For 2.3 — how frameworks prepare organisations for emerging issues — the credible examples are supply chain due diligence expectations, greenwashing scrutiny by regulators, climate-related physical risk to sites and operations, and customer and tender requirements that now ask for carbon data.
