Measure and benchmark everything in relation to your environmental impact, consumption and expeniture, wherever possible.
The three most common metrics include your carbon, water and ecological footprints.
Sustainability reporting is already mandatory in larger organisations and the requriement will soon filter down to smaller organisations. The sooner your business starts to embed environmental change, and record its climate position the better.
Carbon footprint calculations are also a sensible form of risk management for any small business to enable you to make quick decisions regarding future legislation changes, supply chain disruption and hikes in the price of energy. Calculating your carbon footprint, and working to reduce it, can lead to cost savings for your business too.
