Landfilling is long the most common method of disposal for municipal solid waste (MSW). However, many countries seek to implement different methods of MSW treatment due to the high global warming potential associated with landfilling. Other methods such as recycling and incineration are either limited to only a fraction of generated MSW or still produce large greenhouse gas emissions, thereby providing an unsustainable disposal method.

More than 95% of H is synthesized through metal-catalyzed steam methane reforming that produces 11 tonnes of carbon dioxide (CO ) per tonne H . "Green H " from water electrolysis using renewable energy evolves no CO , but costs 2-3× more, making it presently economically unviable.
