全球氣候變化背景下，我國確立的“3060”雙碳目標正在深刻地重塑各類(lèi)資產(chǎn)的價(jià)值邏輯，森林資源資產(chǎn)首當其沖。森林作為陸地生態(tài)系統非常大的碳庫，其固碳釋氧功能通過(guò)市場(chǎng)化機制轉化為可交易的碳匯，成為一種全新的、可量化的增量收益。由此，“森林碳匯資產(chǎn)”從原有的森林資源資產(chǎn)中逐漸獨立出來(lái)，成為評估領(lǐng)域的前沿熱點(diǎn)，它既依附于林木資產(chǎn)，又有其獨特的價(jià)值規律。

Against the backdrop of global climate change, China's "3060" dual carbon target is profoundly reshaping the value logic of various assets, with forest resource assets being the first to bear the brunt. As the largest carbon reservoir in terrestrial ecosystems, forests convert their carbon sequestration and oxygen release functions into tradable carbon sinks through market-oriented mechanisms, becoming a new and quantifiable incremental benefit. As a result, "forest carbon sequestration assets" have gradually become independent from the original forest resource assets and become a cutting-edge hotspot in the field of evaluation. It is not only attached to forest assets, but also has its unique value law.

認知前提：碳匯作為一項資產(chǎn)

Cognitive premise: Carbon sink as an asset

對森林碳匯進(jìn)行評估，首先要明確其資產(chǎn)屬性。一項資源要被確認為資產(chǎn)，須滿(mǎn)足為特定主體所擁有或控制、由過(guò)去事項形成、且預期能帶來(lái)經(jīng)濟利益流入等條件。在國際碳信用機制（如VCS、GS）和國家核證自愿減排量（CCER）框架下，經(jīng)過(guò)項目設計、審定、備案、監測、核查與簽發(fā)等一系列嚴格流程后，特定林地上新增的、具有額外性的凈碳匯量，轉化為可以進(jìn)入碳市場(chǎng)交易的標準合約。此時(shí)，這片林地未來(lái)的固碳能力便具備了清晰的權屬和預期現金流，成為一項合格的資產(chǎn)，即“森林碳匯資產(chǎn)”。

To evaluate forest carbon sinks, the first step is to clarify their asset attributes. To be recognized as an asset, a resource must meet the conditions of being owned or controlled by a specific entity, formed by past events, and expected to bring economic benefits. Under the framework of international carbon credit mechanisms (such as VCS, GS) and nationally verified voluntary emission reductions (CCER), after a series of strict processes including project design, approval, filing, monitoring, verification, and issuance, the additional net carbon sinks added to specific forest lands are converted into standard contracts that can be traded in the carbon market. At this point, the future carbon sequestration capacity of this forest land has clear ownership and expected cash flow, becoming a qualified asset, namely the 'forest carbon sink asset'.

核心評估方法辨析

Analysis of Core Evaluation Methods

與傳統森林資產(chǎn)不同，碳匯資產(chǎn)幾乎沒(méi)有重置成本且實(shí)物形態(tài)特殊，成本法基本不適用。當前主流方法為市場(chǎng)法和收益法。

Unlike traditional forest assets, carbon sequestration assets have almost no replacement cost and have a unique physical form, making the cost method generally not applicable. The current mainstream methods are market approach and income approach.

市場(chǎng)法直接而快捷。 隨著(zhù)全國碳排放權交易市場(chǎng)和試點(diǎn)碳市場(chǎng)的運行，碳配額（CEA）和CCER的交易價(jià)格公開(kāi)、連續，為可比案例提供了絕佳的數據基礎。評估時(shí)，需篩選同類(lèi)項目、同質(zhì)碳信用的近期成交均價(jià)，并核心考量計入期（項目有效期通常為20-40年）、碳匯的持久性與非持久性風(fēng)險（需預留一定的緩沖池或打折扣）、項目類(lèi)型（造林、森林經(jīng)營(yíng)碳匯的交易價(jià)格可能存在差異）等因素，進(jìn)行修正。該方法的挑戰在于，我國CCER市場(chǎng)重啟不久，歷史價(jià)格波動(dòng)劇烈，且交易量尚未完全釋放，基于有限樣本的市場(chǎng)比較可能難以反映其內在的真實(shí)供需均衡價(jià)格。

The market approach is direct and efficient. With the operation of the national carbon emission trading market and pilot carbon market, the trading prices of carbon allowances (CEA) and CCER are open and continuous, providing an excellent data foundation for comparable cases. When evaluating, it is necessary to screen the recent average transaction price of similar projects and homogeneous carbon credits, and focus on factors such as the inclusion period (project validity period is usually 20-40 years), the persistence and non persistence risks of carbon sinks (a certain buffer pool or discount needs to be reserved), project type (there may be differences in transaction prices of afforestation and forest management carbon sinks), etc., and make corrections. The challenge of this method is that the CCER market in China has recently restarted, with severe historical price fluctuations and incomplete trading volume. Market comparisons based on limited samples may not reflect its inherent true supply-demand equilibrium prices.

收益法是更具彈性的內在價(jià)值評估法。 其公式依然是項目計入期內各年碳匯量乘以預期碳價(jià)，再行折現加總。核心參數包括：

The income approach is a more flexible method of intrinsic value assessment. The formula is still calculated by multiplying the carbon sequestration amount of each year during the project's inclusion period by the expected carbon price, and then discounting and adding up. The core parameters include:

其一，年碳匯量預測，需基于樹(shù)種生長(cháng)方程、生物量模型，計算地上地下生物量的年增量，并扣除基線(xiàn)情景下的碳匯量、項目排放及泄漏量，對林學(xué)專(zhuān)業(yè)能力要求出眾。

Firstly, the prediction of annual carbon sequestration requires the calculation of the annual increase in aboveground and underground biomass based on tree growth equations and biomass models, and the deduction of carbon sequestration, project emissions, and leakage under baseline scenarios, which demands extremely high professional competence in forestry.

其二，未來(lái)碳價(jià)預測，這既是核心也是非常大難點(diǎn)。碳價(jià)受全球氣候政策強度、減排技術(shù)突破、市場(chǎng)配額松緊等影響深遠，具有高度不確定性。趨勢外推、基于邊際減排成本曲線(xiàn)的預測、或參照國際成熟市場(chǎng)碳價(jià)加風(fēng)險溢價(jià)的類(lèi)比法，均可嘗試。一種更穩健的思路是將碳匯資產(chǎn)視作一種看漲期權，運用實(shí)物期權模型，評估其在未來(lái)氣候政策趨嚴、碳價(jià)飆升情境下的戰略性?xún)r(jià)值。

Secondly, predicting future carbon prices is both the core and the biggest challenge. The carbon price is deeply influenced by the intensity of global climate policies, breakthroughs in emission reduction technologies, and the tightness of market quotas, and has a high degree of uncertainty. Trend extrapolation, prediction based on marginal emission reduction cost curve, or analogy with mature international market carbon prices and risk premiums can all be attempted. A more robust approach is to view carbon sequestration assets as a call option and use a real option model to evaluate their strategic value in the context of future climate policy tightening and soaring carbon prices.

其三，折現率選取，除了常規的林業(yè)投資風(fēng)險外，還需額外考量碳匯項目的“逆轉風(fēng)險”（如火災將已固定的碳重新釋放）以及政策法規風(fēng)險，對應的風(fēng)險報酬率通常應高于常規林木資產(chǎn)。

Thirdly, when selecting the discount rate, in addition to the conventional forestry investment risks, it is also necessary to consider the "reversal risk" of carbon sequestration projects (such as the re release of fixed carbon from fires) and policy and regulatory risks, and the corresponding risk return rate should usually be higher than that of conventional forest assets.

在評估一片擁有碳匯開(kāi)發(fā)潛力的用材林時(shí)，決不能簡(jiǎn)單地將木材價(jià)值和碳匯價(jià)值割裂評估后相加。二者在經(jīng)營(yíng)決策上存在深刻的協(xié)同與制衡。例如，延長(cháng)輪伐期會(huì )降低木材收獲的凈現值，卻可能因為大樹(shù)持續的固碳累積而顯著(zhù)增加碳匯收益。因此，更高階的評估應構建統一的“林分經(jīng)營(yíng)決策優(yōu)化模型”，以木材和碳匯綜合收益非常大化（或價(jià)值非常大化）為目標，反求非常優(yōu)輪伐期和間伐策略，在此非常優(yōu)經(jīng)營(yíng)方案下評估出的整體價(jià)值，才是生態(tài)產(chǎn)品價(jià)值實(shí)現機制在微觀(guān)資產(chǎn)層面的非常佳體現。這標志著(zhù)森林資源資產(chǎn)評估正從傳統的單維物質(zhì)產(chǎn)出評價(jià)，邁向多維生態(tài)服務(wù)價(jià)值相結合的出彩階段。

When evaluating a timber forest with potential for carbon sequestration development, it is not enough to simply separate the value of wood and carbon sequestration and add them together. There is a profound synergy and balance between the two in business decision-making. For example, extending the rotation period may reduce the net present value of timber harvest, but it may significantly increase carbon sequestration benefits due to the continuous carbon sequestration accumulation of large trees. Therefore, a unified "forest management decision optimization model" should be constructed for higher-level evaluations, with the goal of maximizing the comprehensive income (or value) of wood and carbon sinks. The optimal rotation period and thinning strategy should be reverse engineered, and the overall value evaluated under this optimal management plan is the best embodiment of the ecological product value realization mechanism at the micro asset level. This marks the transition of forest resource asset assessment from traditional single dimensional material output evaluation to an advanced stage of multidimensional ecological service value integration.
