Fig. 1: Marginal abatement cost curve of agricultural NH3 emissions in China.
From: Societal benefits of halving agricultural ammonia emissions in China far exceed the abatement costs
The red dots represent the introduction of specific mitigation options. Only measures with a significant reduction potential (>0.1 Tg NH3–N) are labeled; the blue dotted line represents abatements cost = 0; the RNF is the direct reduction of synthetic N fertilizer (mainly urea) use on croplands without yield loss, since currently the high application rates of N fertilizer in China far exceed crop demand31; LNF represents low N feeding options without decreasing animal productivity; CS represents covered storage measures; IA represents improved manure application options; HA represents housing adaptation options; IFM means improved fertilization management including right source, right place, right time of fertilization and irrigation. Note that in this figure we only give the weighted mitigation potential and weighted cost of the proposed mitigation options for different crops or animals. Details about combinations of mitigation measures are summarized in Supplementary Table 7. Source data are provided as a Source Data file.
