A phased strategy, begining with mutual recognition of methodologies, progressing to dual validation, advancing toward full registry interoperability, could allow Indonesia to balance market access with regulatory sovereignty.

In this study, using Maxent, we modelled the climate-driven habitat shifts and conservation gaps to <em>P. cirrhifolium</em> under current and four Shared Socioeconomic Pathways (SSPs: 1–2.6, 2–4.5, 3–7.0, and 5–8.5) for multiple timeframes from 2021 to 2100. Our results revealed that evapotranspiration, annual precipitation, and temperature seasonality are the major factors affecting the distribution of <em>P. cirrhifolium</em> in the Nepal Himalaya. Habitat modelling reveals that for the current scenario, only 8.74 % of Nepal’s area is predicted to be suitable habitat, with only <em>ca</em> 20 % area occurring within the protected area systems (PAs).

The findings are as follows: the accounting methods for forest carbon sequestration costs include the afforestation cost method, opportunity cost method, comprehensive cost method, and minimum carbon price method, the latter of which is currently the most comprehensive and accurate for cost evaluation. Results also reveal that the influencing factors of forest carbon sequestration costs exhibit three core patterns, that is, the widespread presence of “nonlinearity”, “policy–market duality”, and “natural–artificial substitution relationship”. Moreover, across the full project life cycle, the four major cost categories are afforestation costs, maintenance costs, transaction costs, and opportunity costs. Significant differences are found in cost estimates across countries and regions, and methodological choices also have a great impact on estimation results, thus affecting the reliability of cross-regional comparisons.
