It is commonly known that transport means release exhaust gases into the atmosphere which poses a threat to the natural environment. Therefore, new requirements and stricter regulations on emissions of C2 and other harmful substances are being introduced. This study presents an analysis of different emission sources of anthropogenic and natural origin. The analysis is supposed to show a real impact of transport related C2 emissions on the natural environment. The work includes results of tests concerning application of biocomponents in motor vehicle fuels and their impact on the value of C2 emission. Having in mind the analysis, it can be said that, as compared to other branches of economy and its natural sources, transport is not the major source of C2 emission and application of biofuels is not a factor that is likely to significantly contribute to carbon dioxide emission reduction on a global scale.

This study analyzes the natural and social factors influencing the emergence and publicization of the invasive status of a fast growing bush, gorse (Ulex europaeus), by comparison between countries on a global scale. We used documents collected on the web in a standardized way. The results show that in all the countries studied, there are several public statuses attributed to gorse. The invasive status is the one that is most shared. The other most frequently encountered status are those of noxious weed, and of economically useful. The invasive status is publicized in nearly all countries, including those where gorse is almost absent. We quantified the publicization of the invasive gorse status of gorse by an indicator with 5 levels, and then performed a multivariate analysis that combines natural and social explanatory variables. The results lead us to propose the concept of invasive niche: the set of natural and social parameters that allow a species to be considered invasive in a given socio-ecosystem.
