Just a short walk away from Colorado's State Capitol in Denver is the nation's first carbon-positive hotel,
Populus. It'll open later this year, but began taking reservations in mid-April. The hotel offers 265 guest rooms, two restaurants, event spaces, a rooftop bar, coffee bar and more, all with a unique approach: to sequester more carbon than it produces during its lifetime. The methods it uses are plentiful, from carbon offsetting projects to sustainable construction methods and more.
