Pine tar is a form of wood tar produced by the high temperature carbonization of pine wood in anoxic conditions (dry distillation or destructive distillation). The wood is rapidly decomposed by applying heat and pressure in a closed container; the primary resulting products are charcoal and pine tar .
With the demise of wooden ships, those uses of pine resin ended, but the former naval stores industry remained vigorous as new products created new markets. First extensively described by Frederick Law Olmsted in his book A Journey in the Seaboard Slave States (1856), [3] the naval stores industry was one of the economic mainstays of the southeastern United States until the late 20th century.

Pine tar is produced by slowly burning pine roots, branches, or small trunks in a partially smothered flame.

Birchbark is used to make birch-tar, a particularly fine tar. The terms tar and pitch are often used interchangeably. However, pitch is considered more solid, while tar is more liquid. Traditionally, pitch that was used for waterproofing buckets, barrels and ships was drawn from pine. It is used to make cutler's resin.
Climate change adaptation has garnered more importance in UNFCCC negotiations in the 2020s as opposed to older times, when mitigation was given more focus. Silvopasture systems which integrate trees and other woody plants along with crops, forage and livestock are a highly sustainable strategy that has huge adaptive capacity, besides its mitigation potential.
