Sustainable behavior starts at home. For frequent travelers it is advisable to turn off all electrical appliances, except for freezer and refrigerator, on departure so as to save power and money. Heating or thermostat should also be down regulated to a minimum. You should always travel with small luggage, because the weight of the luggage is also reflected in the CO2 emissions. Furthermore, it is recommended to use a reusable to-go cup or a plastic bottle to act sustainably on the go. In hotels, water consumption can be reduced by multiple use of towels and bed linen and the air conditioning should always be used in short intervals.
