I thought reasonable and you will highest replacing experts regarding analyses since uncertainty regarding replacement masters leads to uncertainty within the minimization overall performance having time and you can ghana chat room circumstances . 4), however, modern-day fuels had higher local differentiation, especially for countries with high commercial times request and you can lower people, much like the conclusions away from an earlier studies . To possess coming analyses, it might be good-for provides spatial information about coming area and you will commercial fuel consumption for each fossil fuel.
Suspicion on the replacing benefits to have timber points is actually analyzed of the having fun with higher and you can reduced substitution professionals to own sawnwood and you will boards. A current review of degree having examined substitution experts getting wood , located the common device displacement component that is in the variety out of opinions used in this research, however, additional information on displacement circumstances of the commodity style of and nation is of use, as well as additional information on end-spends and you can relevant unit lifetimes (elizabeth.g. [5, 8]). Details about replacing advantages for pulp and you may report is restricted, and we also presumed there clearly was zero substitution benefit, however, given the ratio regarding C inside category (25% in order to 34% away from timber products), refining such situations may have higher affects on the net GHG protection. No matter what concerns regarding the actual magnitude regarding replacing advantages, the results certainly reveal that higher minimization gurus can be done as a result of formula you to definitely (1) boost the C maintenance time in gathered wood activities of the favouring long-lived over short-stayed items and bioenergy, and (2) encourage the use of wood activities to change emission-intensive information, e.g. from the strengthening markets. In terms of the economic analyses, similar studies have compared mitigation costs for various mitigation scenarios at the national scale and for specific activities [45, 56, 68]. In this study, we used regionally differentiated economic assumptions by three broad regions (northern interior, southern interior, coastal region) as well as at the timber supply area (TSA) level for the Bioenergy scenarios in order to capture the spatial variation in market price and production cost (Additional file 1: Table S9). The cost and price assumptions associated with the bioenergy scenarios and the substitution effects were TSA-specific depending on residue availability, bioenergy facility type, transportation distance (simple estimates), and fuel mix. We assumed that log prices would be affected if harvest shifted among log grades due to mitigation scenarios. For example, the Higher Recovery scenario was assumed to increase the proportion of logs in lower grades and thus reduce overall average log prices, while the Restricted Harvest scenario was assumed to decrease the portion of top-grade logs, and therefore also reduce overall average log prices. Costs related to forest management were affected if harvest activities were altered by mitigation scenarios, for instance, logging costs increased in conservation scenarios because more dispersed cut blocks were needed to keep the same harvest characteristics (e.g., diameters, tree species, etc.). We also assumed a fixed $50/tCO2e carbon price over the entire period for slashburning as a penalty in the baseline to reflect a possible policy change to include slashburning in BC's existing carbon pricing . Manufacturing costs were also impacted by changes in production efficiency that then depend on the availability of input materials. Additional recovered fiber under Higher Utilization was assumed to be used in HWP following the same proportions as in the baseline, thus a lower manufacturing cost was assumed for pulp and paper production due to higher efficiency, but a higher manufacturing cost for solid wood products because of lower log quality. Similarly, higher manufacturing costs were assumed for all HWP in the conservation scenarios due to lower efficiency. In the LLP scenario, we assumed economy of scales increased manufacturing costs of pulp and paper (+ 2%) and decreased costs for solid wood products (? 2%) .
