Absolute Emissions versus Avoided Emissions

In the context of GHG Emissions and limiting anthopogenic factors of Climate Change the distinction between Absolute Emissions and Avoided Emissions highlights the nature of this sustainability constraint: namely the existence of a Carbon Budget[1]

Since the pre-industrial period to 2011, approximately 1890 Gigatonnes of CO2 (GtCO2) have already been emitted globally, and 2050 GtCO2 up to 2015. Scientific estimations of the remaining global emissions budgets differ due to varied methodological approaches, and considerations of thresholds. Such amounts are linked with some probability to specific target scenarios (eg wikipedia:Special Report on Global Warming of 1.5 °C.
