Sebastian's personal commitment to sustainable development doesn't rest on colossal buildings and pompous declarations but modest actions that, in the end, bear fruit. His home, although very old, is now perfectly insulated and heated with a latest-generation gas condensing boiler. The hot water and electricity they have are presents that the sun gives us every day. For travelling by car, they have chosen an alternative type of fuel that is much more environmentally friendly: liquid propane gas (LPG)! As for their rubbish, by sorting it meticulously and composting organics systematically they have been able to cut down residual waste collection to?once a month! Many little streams make mighty rivers in which our children will be able to bathe without fear?
