Timber - reducing the carbon footprint
It has become increasingly clear over the last decade
that we have to change our approach to building
generally and to building homes specifically as the
materials typically used in construction contribute
significantly to global greenhouse gas emissions.
● The environmental impact of construction is
unsustainably high, with choice of building material
a significant contributor to greenhouse gas
emissions.
● Given the high carbon footprint of cement and steel
production, timber is increasingly a compelling
third option.
● The CO2 captured during photosynthesis gives

materials, but this captured CO2 needs managing
