"A pencil: according to materials used within its manufacture and the environmental impacts resulting from its production.
All products have intricate life histories and environmental consequences.
Data sourced from a ‘a gate to gate’ Life Cycle Assessment on pencil production (from the resources entry into manufacture to the finishing product package). Lower data is from a Life Cycle inventory (LCI) which results in environment Impact categories and normalization value (in Euro).
