The first client of David Green’s Zero Carbon® consulting practice, David Sguazzin, has cut the carbon footprint of his modest home on Long Island, NY by approximately 4 tons of carbon dioxide per year and is saving over $1,100 per year on heating and electric bills. David Sguazzin is earning a 46% return on his investments in insulation, air sealing and triple-glazed windows. The triple-glazed windows were made by the David Sguazzin and fitted to the inside of the existing single-pane windows using a technique pioneered by David Green on his own home. 
“Working with David Green was an absolute pleasure, he guided me through the process with his experience in lowering my energy expenses and my overall carbon footprint.” Said David Sguazzin.
Before engaging Zero Carbon® LLC, the approximately 1,000 square foot, single-story house’s heating and electric bills were about $3,500 per year. Today, they are about $2,400 per year saving David Sguazzin $1,100 per year.  The total investment was about $1,300 in materials. The fee paid to Zero Carbon® LLC was 1x the annual savings on the bills or $1,100. The 46% return on investment includes the fee.
On David Green’s own home, the return on investment in a more comprehensive program of energy reduction, heat pumps and solar panels that cut the house’s carbon footprint and utility bills to zero, was 15%. 
David Green’s “fab four” recipe for making money by cutting your carbon footprint has now been proven on houses ranging from 1,000 square feet to 5,400 square feet.
