Fig. 1From: The default methods in the 2019 Refinement drastically reduce estimates of global carbon sinks of harvested wood productsGlobal carbon stocks and carbon removals for harvested wood products (HWPs). “SCA,” “AFA,” and “PA” denote the default (Tier 1) method for the stock-change approach, atmospheric flow approach, and production approach, respectively, according to the 2006 Guidelines [12]. “PA13” and “PA13i” denote the default (Tier 2) method for the production approach assuming that the initial years in carbon stocks are 1900 and 1961, respectively, according to the 2013 Guidance [27]. “SCA19,” “AFA19,” and “PA19” denote the default (Tier 1) method for the stock-change approach, atmospheric flow approach, and production approach, respectively, according to the 2019 Refinement [38]Back to article page
