“…While a portion of studies addressing carbon quantification rely on other researcher's estimates of carbon storage and sequestration (e.g., References [70,71]), we used a tree-based approach and derived the carbon fixed in each forest plot considering tree size and species-specific allometric equations to convert tree size to biomass and carbon. However, we identified a trade-off between carbon specificity accuracy and the number of plots used.…”

Carbon storage and sequestration are key ecosystem services critical to human well-being and biodiversity conservation. In a warming context, the quantification and valuation of carbon storage and sequestration is important in ensuring that effective incentives are put in place to tackle climate change. The quantification and valuation of ES such as carbon storage and sequestration requires the calculus of actual values and prediction, however, it usually does not include key processes that can indirectly influence carbon dynamics (i.e., risk, conservation or management). Here, we define a multifactorial approach to value ecosystem services based on two stages: (1) a biophysical approximation that integrates yearly supporting ecosystem services (i.e., quantification of carbon storage and sequestration) and (2) a weighing approach including factors that indirectly influence carbon storage and sequestration or that deserve specific attention (i.e., risk, conservation or management factors). The quantification of carbon storage and sequestration indicated that Spanish forests store on average 43 Mg C ha−1 and sequestrate on average 1.02 Mg C ha−1 year−1. Forest structure was a strong determinant of carbon storage and sequestration in Iberian forests, hence there was a strong spatial variation in the carbon sink. We adapted the weighting values to a financial cap and the monetary value of carbon increased more than four times when the weighting factors were taken into account. Finally, we argue that a multifactorial approach to value supporting ecosystem services incorporating aspects related to conservation and risk prevention can facilitate ecosystem service valuation and assist policy makers and stakeholders to establish payment service policies.

In recent years, with the development of social economy, there is a tendency of increasing CO 2 emission in the world. As a greenhouse gas, the increase of CO 2 emissions will bring many adverse effects on the global climate and environment. So reducing CO 2 emissions is very important, because it is related to human development. The study aims to investigate what determinant variables would affect the CO 2 emission per capita, and the relationship between its emissions and those determinant variables. Based on several hypotheses, this paper builds a linear regression model, in which the determinant variables are GDP, electric power consumption, combustible renewables and waste, fossil fuel energy consumption in total energy consumption, trade, motor vehicle per 1000 people and urban population, established by the data of 102 countries in 2017. In the end, we draw a conclusion that GDP, electric power energy consumption, fossil fuel consumption, and motor vehicle per 1000 people play essential roles on carbon emission per capita at the national and regional levels. These findings would guide future policy making by balancing GDP growth and CO 2 emission as well as the appropriate use of fossil fuel energy in the total energy consumption. These findings are of great significance to the guidance of CO 2 emission policies, so that we can achieve the reduction of CO 2 .

“…The determinants of feasibility of carbon project development include the amount of carbon stock observed, historical business as usual, carbon price, and associated costs [31,48]. Carbon price negotiations are still going on [26,49]. The voluntary carbon market is currently one of the main frameworks within which carbon stock can be sold from CBFM [23,48].…”

In response to the pressing global challenges of climate change, community based management of miombo woodlands in Tanzania is promoted for carbon credit project development. However, evidence on its feasibility is scanty and questionable. This study examined the economic feasibility of carbon credit project development in community based forest management (CBFM) using four similar miombo woodlands from Southern highlands. The analysis was based on 144 sample plots from managed woodlands and 100 plots from business as usual (BAU) (open access). Allometric equation was applied to convert biomass to carbon per hectare. Improved carbon stock was determined and its economic value ascertained based on global voluntary carbon markets. Project feasibility analysis was performed using discounted cash flow, internal rate of return, and benefits/costs methods. Annual opportunity cost and variable costs were subtracted from total revenue to obtain annual net profit. The annual rate of return on investment was calculated by dividing profits by total costs. It was revealed that carbon stock improved significantly in CBFM compared to BAU ( < 5%). The improvement had positive net present value and benefit-cost ratio of 1.83. Moreover, sensitivity analysis showed that if any unexpected situation occurs, the project will still be of worthiness. The findings are useful to enrich the debate on carbon credit development under community based management of miombo woodlands in Tanzania.
