In fact, cutting waste or switching to renewable energy can lower running costs and improve resilience.Knowledge gaps – You can’t manage what you don’t understand. Start by learning about climate issues and how they relate to your sector. Once you know the basics, the next steps become clearer.Time constraints – Running a small business can be all-consuming. If time is tight, nominate a team member to take the lead or seek help from a specialist.
