Travelers are encouraged to refuse potential waste items such as single-use straws or individually packaged condiments. The vehicles, lodges and camps throughout the Greater Yellowstone Ecosystem will be stocked with bulk foods that will be transported as individual meals in reusable containers. Napkins and biodegradable foods will be composted by the team, while hard-to-recycle materials will be sent to TerraCycle , a world-leading company that specializes in recycling difficult outputs. There is no better company in achieving this mission than Natural Habitat Adventures, which just celebrated 10 years of being 100 percent carbon neutral — in 2007, the ecotourism pioneer became the world’s first carbon-neutral travel company. Its  carbon offset program has thwarted more than 34.5 million pounds of carbon dioxide emissions generated through the company’s global nature adventures.
