No one turns on the heat or air conditioning at home and leaves the doors wide open. It wastes energy and money. Yet many stores and restaurants do exactly that every day. When doors stay open while HVAC systems run, as much as half of the energy being used escapes outside.

That wasted energy shows up on your receipt through higher prices. It also shows up in the atmosphere. A single small store keeping its doors open year-round can release as much carbon as several long-distance flights.

You can help stop this.

• Support shops and cafes that keep their doors closed or display the Keep It Closed logo.

• Close doors behind you when you can.

• Talk to staff or managers about it. A polite conversation can go a long way.

• Choose to spend your money in places that value efficiency and care about the environment.

Every time you close a door, you help cut waste, lower costs, and protect the planet. Keep it closed.
