Make it relevant to their lives
This is your family after all. You know lots about what they like to eat, where they like to shop and what they do for fun. Look for areas where you could help them make quick wins. Do they always do a massive, pre-holiday Penneys shop? Could you suggest an alternative – or even better – take them on a shopping trip to your favourite vintage shops!
And if there’s a family member who fancies themself as the next Master Chef, you could challenge them to a plant-based cook-off. And for the bill-payer(s) of the house, you’ll definitely see some sway when you point out the serious economic savings that can be made by switching to a green energy supplier, it’s not just an environmental win!
