The carbon costs associated with SRC are: the planting, farming and chipping of the SRC plantation, generally done with fossil fuel powered machinery; the crops require herbicides during establishment, fertiliser throughout growth, and occasional pesticide treatment – these chemicals require substantial amounts of energy and potential fossil ...
IPCC estimates that land-use change (e.g. conversion of forest into agricultural land) contributes a net 1.6 ± 0.8 Gt carbon per year to the atmosphere. For comparison, the major source of CO 2, namely emissions from fossil fuel combustion and cement production, amount to 6.3 ± 0.6 Gt carbon per year. [15]
A 2020 report estimated sequestration in forests (so including capture) at US$35 for small quantities to US$280 per tonne for 10% of the total required to keep to 1.5 C warming. [182] But there is risk of forest fires releasing the carbon.
An important consideration in such efforts is that forests can turn from sinks to carbon sources. [18] [19] [20] In 2019 forests took up a third less carbon than they did in the 1990s, due to higher temperatures, droughts [21] and deforestation. The typical tropical forest may become a carbon source by the 2060s. [22]
An important consideration in such efforts is that forests can turn from sinks to carbon sources. [42] [43] [44] In 2019 forests took up a third less carbon than they did in the 1990s, due to higher temperatures, droughts [45] and deforestation. The typical tropical forest may become a carbon source by the 2060s. [46]
Carbon farming enhances carbon sequestration in the soil. Carbon farming is a set of agricultural methods that aim to store carbon in the soil, crop roots, wood and leaves. The technical term for this is carbon sequestration. The overall goal of carbon farming is to create a net loss of carbon from the atmosphere. [1]

In section C: "Policy approaches and positive incentives on issues relating to reducing emissions from deforestation and forest degradation in developing countries; and the role of conservation, sustainable management of forests and enhancement of forest carbon stocks in developing countries" environmental and social safeguards were introduced ...
