Peculiarities of Using Uncertainty in Environmental Guides

Significant attention is paid to common questions relative to the methods of the expression of the uncertainty of measurements and the estimates of the results of the definition of the environmental characteristics of global objects. The bases analysis of uncertainty and its main sources are considered. Peculiarities of the expression of uncertainty and the variants of its estimation in international metrological and environmental guides are shown. Basic positions concerning the uncertainty estimates of obtained results, shown in well-known international guides of inventory of greenhouse gases, are considered. The use of international metrological guidance of expression of measurements uncertainty in development of new and reconsideration of old international environmental guides is recommended
