In this study I use the US pulp and paper industry to explore the equity market’s valuation of environmental capital expenditures. I replicate and extend a study by Clarkson, Li, and Richardson that bifurcates the industry into high and low polluting groups. As with their study, I find evidence indicating that the market values environmental capital expenditures by over-compliant firms while attaching no such value to the same expenditures by minimally compliant firms. I do not find that the market assesses unrecorded liabilities to firms that are minimally compliant. My extension also seeks to address two possible specification issues in the Clarkson, et. Al. approach.  The first, levels model they used is unbiased but inefficient.  Their model scaled by common shares outstanding attempts to rectify this inefficiency but may not be the optimal choice of scaling variable. My results suggest that a “Best Available Technology” approach to environmental regulation may carry additional incentives provided by the capital markets.

In the context of global climate change, energy conservation and greenhouse effect gases (GHG) reduction are major challenges to mankind. The forestry-pulp and paper industry is a typical high energy consumption and high emission industry. We conducted in-depth research on the energy flows and carbon footprint of the forestry-pulp paper industry. The results show that: (1) The main sources of energy supply include external fossil fuel coal and internal biomass fuel black liquor, which supply 30,057,300 GJ and 14,854,000 GJ respectively; in addition, the energy produced by diesel in material transportation reaches 11,624,256 GJ. (2) The main energy consumption processes include auxiliary engineering projects, material transportation, papermaking, alkali recovery, pulping and other production workshops. The percentages of energy consumption account for 26%, 18%, 15%, 10% and 6%, respectively. (3) The main sources of carbon include coal and forest biomass, reaching 770,000 tons and 1.39 million tons, respectively. (4) Carbon emissions mainly occur in fuel combustion in combined heating and power (CHP) and diesel combustion in material transportation, reaching 6.78 million tons and 790,000 tons of carbon, respectively. (5) Based on steam and electricity consumption, the indirect carbon emissions of various thermal and electric energy production units were calculated, and the key energy consumption process units and hotspot carbon flow paths were further found. This research established a theoretical and methodological basis for energy conservation and emission reduction.
