Many industries, rather than simply responding to increasingly stringent regulation, are now actively seeking to develop more environmentally benign products and processes. Life Cycle Assessment (LCA) is one of the best known tools for assessing the environmental impact of activities.
Life Cycle Assessment is a process of compilation and evaluation of inputs, outputs and potential environmental impacts of a product system throughout its lifecycle.

The changes account for the abolishment of the Code for Sustainable Homes and revisions to BS EN ISO 14044 and ISO 21930. The section on BREEAM was amended to include the 2018 New Construction scheme. There is also an update on similar schemes and the implications for timber.
Life-cycle costing is a decision-making technique which takes into account both initial and future costs. For buildings and structures this usually means considering not just capital costs but relevant costs in use (operational costs) such as maintenance, component replacement, utilities, managing the asset for a given period, and end-of-life costs....
As a construction material, timber has a very distinct advantage over the alternatives, namely that trees are a living thing and therefore a renewable resource. With the use of correctly managed forests, timber represents an excellent way of creating a more sustainable construction industry.
