摘要：

The objective of this study was to conduct a gate-to-gate life cycle assessment of hardwood lumber production in selected districts (Haripur and Abbottabad) of the Hazara region, Pakistan. Primary data regarding inputs and outputs from sawmills were collected through questionnaire surveys of twenty-two (22) sawmills in the Haripur district and eighteen (18) sawmills in the Abbottabad district of Pakistan during the year 2017-2018. Gate-to-gate life cycle assessment was conducted for a reference unit of 1.0 m(3)of planed dry hardwood lumber. Production-weighted average data were modelled in SimaPro v.8.5 for ten environmental impact indicators. Diesel consumption in the transport of raw materials, purchased electricity consumed at the sawmills and urea formaldehyde resin used for filling cracks in the hardwood lumber product had the highest contributions to all the environmental impact categories evaluated. The carbon stock can be used to offset the carbon footprint of hardwood lumber production in Pakistan.
