Greenline House is a carbon footprint labelling tool for wooden houses.
The tool calculates the cradle-to-gate life cycle greenhouse gas emissions of procuring, manufacturing and constructing a wooden house, taking into account both emitted and sequestered carbon.
The calculation methodology is based on life cycle assessment studies and databases, and adheres to the PAS 2050 specification for the assessment of the life cycle greenhouse gas emissions of goods and services, self declared; and the ISO/TS 14067:2013 standard (Greenhouse gases -- Carbon footprint of products -- Requirements and guidelines for quantification and communication).
Why wooden houses?
Wooden houses have the potential to alleviate or even reverse climate change because wood in itself is carbon neutral and with sustainable forestry management it is possible to increase the net carbon pool of the Earth. Additionally, wood is lighter and requires a lot less energy to work with, compared to ordinary brick and mortar houses.
