Historical contribution by country of three greenhouse gases (CO2, CH4, N2O) to the climate change and Equity principle

The historical contribution by country to climate change can be used as a basis of analysis for a second period of commitments to the burden share. The historical greenhouse gases emission inventory is an important tool to evaluate the common but differentiated responsibilities of groups according to the principle of the UN Framework Convention on Climate Convention (1992). This paper aims to discuss the differences among the meaning of the GHG historical emissions in terms of development patterns and suggests that different weights for different sectors should be taken into account. GHG emissions due to enteric fermentation from domestic livestock, for example, are linked to different regional activities such as food production, cultural expression or even religion meaning, depending on the region analyzed. Emissions due to fossil fuel sector represent in the majority a not feasible consumption pattern in terms of sustainable development
