             abstract = "In the Brazilian Amazon, 53% of deforestation from 2012 to 2020 
                         occurred on private landholdings (PL). This highlights the need to 
                         protect the primary (PF) and secondary (SF) forests in PLs, which 
                         are important carbon stocks and sinks for mitigating climate 
                         change. Quantifying carbon stocks in private PRP can help the 
                         development of Reducing Emissions from Deforestation and Forest 
                         Degradation (REED+) projects, and renvironmental service payments 
                         (ESP), promoting landowner access to carbon markets. These 
                         mechanisms are novel tools for environmental conservation, besides 
                         protection actions to safeguard the compliance of environmental 
                         legislation. We aimed to understand the role of PRP in the 
                         Brazilian state of Par{\'a}, (PA) which concentrated 39% of the 
                         deforestation in the Brazilian Amazon from 2012 to 2020, in 
                         protecting carbon stocks and sinks, by using multi-satellite data 
                         products, including: a) Primary forest cover in 2020 from 
                         PRODES/INPE; b) SF age maps from the MapBiomas project 
                         (1985-2020); c) Aboveground Carbon map for 2020 from European 
                         Space Agency CCi project (2020); and d) Rural proprieties 
                         boundaries in 2018 from the Radiography of the Forest Code 
                         Project. PL covers about 26.1% of PA. Large rural properties 
                         account for 59% of the total (32.2 Mha) and this class alone 
                         retains 8 million ha (Mha) of PF. In terms of carbon stocks, all 
                         PRP size classes (small, medium, and large) concentrate 1.44 PgC, 
                         of which 71.5% (1.03 PgC) is found on large properties. Small and 
                         medium-sized properties stock only 28.5% of the total. When 
                         evaluating vegetation surplus in legal reserves (LRs), a kind of 
                         mandatory protected area for every PL under Brazilian law, large 
                         properties also accumulate the largest areas (1.8 Mha vs. 741 
                         thousand ha in mediun and smallholding), representing a carbon 
                         stock of ~794.2 TgC that could be emitted under legal 
                         deforestation requests. When evaluating the vegetation deficit in 
                         PA, large properties accumulate 1.5 Mha (57%), medium and 
                         small-sized properties accumulate 872 thousand ha (34%) and 268 
                         thousand ha (9%), respectively. Of PA's total SF areas (6.6Mha), 
                         2.8 Mha are under PL, representing a removal potential of about 
                         5.18 TgC year-1. Large properties host 1.4 Mha of SF (50.5%), 
                         while small and medium-sized properties account for 1.38 Mha 
                         (49.5%). Restoring SF on PL could meet 50% of the state's 
                         restoration target for 2030 but only 21% if considering the rules 
                         of current PA State Policy on Climate Change (SF > 10 years old). 
                         We conclude that large rural properties hold significant carbon 
                         stocks in PF and SF, being important targets of environmental 
                         regularization under the Brazilian law, which could also assist PA 
                         with meeting the environmental goals of its climate agenda. We 
                         indicate that areas with forest surpluses must be protected to 
                         reduce environmental liabilities, through the institution of LR 
                         quotas, and incentives to forest restoration and ESP projects.",
