Abstract:
The constant global concern about the effects of greenhouse gas (GHG) emissions on climate stability requires a comprehensive examination. This study investigates the evolution of three primary greenhouse gases—carbon dioxide, methane, and nitrous oxide—from 1990 to 2021, across the macro-regions of Romania, that were created in 1998 by the association of county councils to coordinate the regional development necessary for Romania to join the European Union. The macro-regions are Bucharest-Ilfov, North-East, Center, North-West, West, South-East, South-Muntenia and South-West-Oltenia.
Utilizing data sourced from the EDGAR (Emissions Database for Global Atmospheric Research) database, which categorizes emissions by sectors of activity, we gain insights into the contribution of each sector to total GHG emissions in Romania.
Change Point Analysis is used to understand the shifts in CO2, CH4, and N2O levels over time. Were identified dominant change-points alongside with minor fluctuations, all significant at the 99% level. Additionally, temporal trend analysis using the non-parametric Mann-Kendall’s test and Sen’s method identify and quantify monotonic annual trends in GHG levels.
Overall, this study significantly contributes to the understanding of the evolution of GHG emissions in Romania over the past three decades, highlighting regional and national emission trends. Moreover, it shows the contributions of different activity sectors at the regional scale, enhancing our understanding of their long-term trends. These findings serve as a good basis for developing targeted policies aimed at mitigating GHG emissions and adapting to future climate challenges.
