The aim of the study is using systematic literature analysis method -literature overview -identify the factors, which affect the competitiveness of a higher education institution in the conditions of globalization. Qualitative methods, as well as systematic literature analysis method -literature overview have been used in the study. More than 6000 scientific articles were considered to choose 20 full text articles for in-depth analysis. Main conclusions and results -the systematic literature analysis method -literature overview is a convenient tool for systematizing, selecting and collecting information about the research subject, using author's articles, which have already gathered key information from a number of researchers of a specific topic together; the competitiveness of higher education institution is influenced by the internal factors that are formed by the internal environment of the higher education institution and external factors that are formed by the external micro-environment and macro-environment influenced by the state policy; an analysis of the internal and external factors of an institution is important in order to create competitive advantages in a higher education institution.

In terms of Kyoto protocol, the reduction of CO2 emissions of the transport used in tourism is an important goal for Latvia. Based on a top-down and a bottom-up approach, the CO2 emissions of tourism transport and its types were estimated, while analysing the relation between the CO2 emissions from tourism transport and the relevant input of the tourism transport as part of GDP and vice versa. The results concerning the period 2010 till 2017 showed that the CO2 emissions caused by tourism transport rose from 996.8 x 10 3 kg/km to 1527.3 x 10 3 kg/km. The aviation transport associated with the increased tourism activity is the main cause for the increase of CO2 emissions in Latvia. The connection between the CO2 emissions from tourism and the contribution of tourism transport to GDP is linear. The trend in increase of CO2 emissions in the tourism industry is similar to that of other industries.

The tourism has a close relation to the travel and tourism transport. Transport is the source of CO2 emissions. The aim of the research was to inspect the tourist transportation (TT) CO2 emissions caused by the tourist overnight trips, because any similar analysis up until now has not been made. For the determination of CO2 emissions from the TT a hybrid (top-down and bottom up) approach, correlation, regression was used. The author’s proposed algorithm for determining CO2 emissions from the TT is useful in the circumstances when there is not sufficient statistical data. In the research of regions of Latvia (NUTS 3) from 2012 to 2017, it was determined that the TT overnight trips indicated a reduction of CO2 emissions of 475 t/year. It is a positive approach in order to reach reduction of CO2 emissions according to the EU criteria for 2030; however, it left a negative impact on the national GDP. Finding solution to this economical problem is the aim of the next researches.
