Trees
reduce residential heating
costs by 10-15% (through windbreak)
Each healthy tree can reduce air borne dust
particles by as much as 7,000 particles per litre of
air, thus a healthy tree is a free standing air conditioner
and purifier. About 500 full-sized trees absorb the carbon
dioxide (CO2) produced by a typical car driven 20,000 km/year.
Heating the average Canadian home with oil produces 7
tons CO2 per year, with natural gas 5 tons and with elec-
tricity 1.3 tons CO2 per year. An economy car produces
6 tons of CO2 driven 20,000 km (using gas), a heavy
truck on the same distance (using diesel) 26 tons
of CO2. On average, 98 trees capture and
store 1 ton of airborne carbon di-
oxide every year. Every day,
a large tree
provides
enough oxy-
gen for four
people. Over
80 years, the
average Cana-
dian tree absorbs
200 kg of carbon dioxide.
