Environment

Concrete production is responsible for 8% of the worlds CO2 emissions annually, this is comparable to the total annual CO2 emissions from all the worlds forest fires. Constructing an average house 75m2 using a concrete base will release approximately 10,000m3 of CO2 Gas.

Annual concrete production is responsible for 9% of global fresh water consumption, this is comparable to the flow rate of the Niagara falls for 350 hours (which is 3 billion m3 a year). Constructing an average house 75m2 using a concrete base will consume approximately 9.5m3 of fresh water.

RESOURCES CONSUMED BY CONCRETE PRODUCTION EVERY YEAR
EVERY CUBIC METER OF CONCRETE CONSUMES THIS RATIO OF RESOURCES
Emissions caused by Cement Mixer Trucks
Damage to the landscape by huge cement quarries
Concrete Emits 2 Billion Tonnes of Co2 every year - it outweighs the combined carbon mass of every tree, bush and shrub on the planet
3.6 Billion Tonnes of Fresh Water used every year to Manufacture Concrete

The construction of an average house with a footprint of 60m2 will take.......17 Loads

  • 4 Loads Of Ready Mix Concrete
  • 2 Loads Of Concrete Blocks
  • 6 Loads Of Stone Aggregates
  • 4 Loads Surplus Soil Removal
  • 1 Load Of Miscellaneous Building Materials

Minimising the use of ConcreteThe Environmental Impact

The Environmental Impact of constructing an average house base with a ground floor area of 60m2, using concrete in a strip foundation, rising walls & sub floor, requires the following materials:

  • Ready Mix Concrete & Concrete Blocks 44m3
  • Fresh Water Volume 8m3
  • Deliveries to site @ 20 tonnes each 19 truck loads
  • Diesel fuel used 422 litres

Using this amount of concrete will lead to the following emissions of CO2 gas

  • CO2 Gas Emission from Concrete 18 Tonnes/10300m3
  • CO2 Gas emissions from Fuel 1.13Tonnes = 628m3
  • Water Consumption 8000 litres
