Lightly sitting on the coast of Finland's Helsinki, the Nolla Cabin is the greatest example of zero emissions living. The plywood A-frame structure consists of a single room with two beds and a cooking station. A Wallas stove runs off of renewable diesel and electricity is provided by solar panels on the roof. WiFi is out but a wall of glass looking out over the sea provides all the entertainment you need. The tiny dwelling was built by renewable energy company Neste as part of their "Journey to Zero" campaign to promote a zero-waste lifestyle and its rent will be donated to The Ocean Cleanup.
