Operation Net Zero.

HSEQ isn’t just safety — the “E” is for Environment. Read the four-card primer, then run a sustainability plan for a small contractor. Spot the genuine wins and the greenwash traps.

Site waste & segregation

Construction creates roughly a third of all UK waste. Skips are colour-coded by type. Putting the wrong thing in the wrong skip is illegal and expensive.

Net zero & carbon

The UK’s legal target is net zero by 2050. For an MEP contractor the big levers are fuel, materials, and the buildings we install in.

Pollution prevention

One litre of diesel can pollute a million litres of water. Spill kits go on every site and van — not optional.

ISO 14001

The international standard for managing environmental impact. Often required by clients before you can tender for a job.

Bonus activity

Operation Net Zero.

Scenario: Greenfield & Sons Ltd is a 65-employee plumbing & heating contractor with one head office, a small workshop & yard, and a fleet of nine diesel vans. The new MD wants to halve the company’s carbon footprint by 2030. The bank has approved a one-off sustainability budget. Your job: click cards into your plan to maximise carbon saved within budget. Watch out for tempting-but-pointless choices.
