The products local companies use generally have a much lower carbon footprint than those you will find at larger, global operations and companies. Try to pack a reusable water bottle for your trip to Las Vegas. This will help to save on the number of plastic water bottles you use on your trip which contribute a huge amount of waste to the environment. If you will be going on a tour when you are in Las Vegas try to stick to those that have smaller groups as groups with fewer people tend to have less of an environmental impact. On that note go ahead and ask your tour provider what kind of environmental initiatives they offer to give back to their community and their environment.
