There is a world of untapped opportunities to make our everyday life more sustainable. It’s the world of green service innovation: apps that make it easy to switch to renewable energies; to start renewable energy production; to live carless; to choose and drive electric vehicles; to grow vegetables; to buy local organic food; to trace products’ origin and footprint; to lend, borrow, rent items when needed; to save energy and water; to reduce waste; and thousands more positive actions. Some of these lifestyle changes have relatively small effects on our carbon footprint, while others can have massive impact. Using a pure renewable energy player can cut our carbon footprint nearly by half. Living carless can bring about another 20% reduction in our carbon emissions. Growing and eating local organic fruits and vegetables can add a further 15% reduction.
