I felt reasonable and you may high substitution advantages on analyses once the uncertainty about replacement advantages results in suspicion into the minimization abilities for opportunity and you can points . 4), however, modern fuels got greater local differentiation, specifically for countries with a high commercial times demand and low people, much like the findings regarding an early on data . Getting future analyses, it might be great for enjoys spatial details about future community and commercial fuel useage for each fossil fuel.
From inside the remote communities, power fool around with is evolving due to several apps (the Brush Times having Rural and you will Remote Teams (CERRC) system , the latest Native Away from-Diesel Step , along with 2018 this new CleanBC bundle revealed the goal to reduce by 2030 the fresh new diesel consumption in-off-grid communities of the 80%
Suspicion regarding the replacement pros for wood affairs try examined by playing with large and you may lower substitution pros to own sawnwood and you will panels. A recent writeup on training which have analyzed replacing masters to have wood , discovered the common tool displacement component that is within the range out-of beliefs found in this study, however, additional information on displacement facts of the item method of and you may nation would be beneficial, and additionally additional information on prevent-spends and you can relevant tool lifetimes (e.g. [5, 8]). Information on substitution advantages having pulp and you can papers is restricted, and now we thought discover zero substitution work with, however, given the ratio regarding C inside classification (25% so you’re able to 34% away from wood merchandise), polishing these types of affairs may have highest affects on the net GHG avoidance. Whatever the concerns regarding genuine magnitude out of replacing pros, the performance demonstrably demonstrate that greater mitigation benefits can be done as a result of regulations one (1) improve the C preservation time in harvested timber circumstances because of the favouring long-resided more than short-existed situations including bioenergy, and you can (2) enable the usage of wood products to restore emission-extreme material, elizabeth.grams. from the building industry.
Yet not, no change in field costs of HWP are assumed in any situation while the intellectual dating HWP costs are usually influenced by higher-measure areas whenever you are journal places is relatively regional
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%) .
