Do you really need to rent a car when you travel? Not only can it be expensive to rent and park the car, it may be unnecessary in large cities. Research ahead of time to find out if there is public transport from the airport in your destination city. Look at rail and bus lines, and use apps to help plan your itinerary. Not only will you be greener, you'll save money and a lot of time, too. Taking a train from Newark to New York City, for example, is often far cheaper and faster than taking a taxi.

You can compensate for emissions when you fly by buying something called "carbon offsets." These purchases use your money to "green" your travel by supporting forest protection or tree plantings. But since the carbon offset industry is unregulated, it's important to make sure your purchase actually does what it was intended to do. Look for carbon offsets that are endorsed by independent groups like the Climate Action Reserve or the American Carbon Registry.

In addition to a swimsuit and sunscreen, consider adding these eco additions to your carry-on bag when you travel. A lightweight reusable tote bag can come in handy when you're shopping so you can skip disposable bags. A reusable water bottle can be used during the whole trip to help skip plastic bottle usage; refill it at airports, in hotels and even at restaurants. And consider bringing a multi-use bar soap that works as a shampoo and body wash so you don't use mini amenity bottles. Break it up into small pieces so you'll always have a fresh piece wherever you go.
