Measurement guidelines for the sequestration of forest carbon

Abstract

Measurement guidelines for forest carbon sequestration were developed to support reporting by public and private entities to greenhouse gas registries. These guidelines are intended to be a reference for designing a forest carbon inventory and monitoring system by professionals with a knowledge of sampling, statistical estimation, and forest measurements. This report provides guidance on defining boundaries; measuring, monitoring, and estimating changes in carbon stocks; implementing plans to measure and monitor carbon; and developing quality assurance and quality control plans to ensure credible and reproducible estimates of the carbon credits. Expected users include entities, e.g., individual landowners, industrial forestry companies and managers of utility company lands, within the United States

Organic Carbon Stocks, Dynamics and Restoration in Relation to Soils of Agroecosystems in Ethiopia: A Review

“…Carbon content in soil samples can be directly determined by measuring soil variables. The most direct SOC determination involves collecting soil samples in the field, and samples can be analyzed in the laboratory by combustion techniques (Pearson, 2007;Hairiah et al, 2010). This method includes wet and dry combustion and various types of infrared spectroscopy.…”

“…A number of ground-based surveys are conducted to quantify SOC stocks (Pearson et al, 2007;Hairiah et al, 2010). The purposes of these studies were to determine the ways of CO 2 emission as well as identify and measure changing soil carbon stocks (Lal, 2004).…”

Biomass Stock and Carbon Sequestration in a Chronosequence of Pinus massoniana Plantations in the Upper Reaches of the Yangtze River

“…The total carbon stock in the forest ecosystem is then converted to tons of CO2 equivalent by multiplying it by 44/12 or 3.67 of the molecular weight ratio of CO2 to O2 in order to understand the climate change mitigation potential of the study area [40].…”

Opportunities for implementing REDD+ to enhance sustainable forest management and improve livelihoods in Lombok, NTB, Indonesia

“…The number of sample plots (n) for estimating carbon stock was determined with the following equation (1): (Pearson et al 2007;Hirata et al 2012) n ≥ (tc/e) 2 (1) where e is the allowable error rate, c is the expected coefficient of variation, and t is the value for a 95% confidence interval at the specified degree of freedom. The value of t is constant and usually substituted by 2.…”
