Cyclical convergence in per capita carbon dioxide emission in US states: A dynamic unobserved component approach
(Elsevier, 2021-02-15) LUCAS-SANTOS, SONIA; DELGADO-RODRÍGUEZ, MARIA JESÚS; CABEZAS-ARES, ALFREDO
In this paper we evaluate whether the US states have been able to achieve convergence in their carbon emission cycles which may be a key factor in taking a leap as regards the development of a US climate change policy. The use of a dynamic unobserved component approach and a time-varying parameter model enable estimation of the short run dynamics of energy convergence over the extended period 1960e2017. To date, this type of analysis has not received enough attention in the literature. The results reveal the existence of cross-state links in the fluctuations of CO2 emissions, although the degree to which a good part of the states are co-moving is weak. We also find that cyclical convergence patterns differ considerably in both the level and trajectories across the US states. The difficulties in increasing synchronization of the US CO2 emissions highlight the importance of the states to lead climate change mitigation actions. The present study presents valuable information of interest regarding the short-run characteristics in carbon dioxide emissions, for better understanding of factors affecting CO2 mitigation policies.
Cyclical fluctuation patterns and decoupling: towards common EU-28 environmental performance
(Journal of cleaner production, 2018-02-20) DELGADO-RODRÍGUEZ, MARÍA JESÚS; CABEZAS-ARES, ALFREDO; LUCAS SANTOS, SONIA
The EU-28 is one of the largest emitters of CO2 in the world and the most committed to reducing emissions. However, the national environmental strategies of the Member States are still diverse. This study is aimed at evaluating the environmental performance of European economies by analysing the fluctuations of CO2 emissions and their links with economic activity over the period 1950e2012. The methodological framework is based on a dynamic factor analysis to determine an index of the EU fluctuation of CO2 emissions in parametric form. This index can be used to monitor the progress towards common behaviour across Member States, with a time-varying recursive method. Following this approach, we also track the efforts made to decouple CO2 emissions from GDP. Based on these analyses, we develop a CO2 emissions-GDP linkage matrix to attain useful information on the EU Member State environmental performance.
Dynamics of Cyclical Convergence and Decoupling in the Environmental Performance of Spanish Regions
(MDPI, 2020-10-16) CABEZAS-ARES, ALFREDO; DELGADO-RODRÍGUEZ, MARÍA JESUS; LUCAS-SANTOS, SONIA
Spain is aiming at moving towards a low-carbon economy. The success of this task will depend on the capacities of Spanish regions to follow the national energy and climate strategy and decarbonize their economies. In this paper, we analyze the CO2 fluctuations and links with economic activity, throughout the period 1990 to 2018, using dynamic factor and recursive estimation models. We confirm the robustness of our results by testing the stability of the estimated parameters. Our findings show that the dynamics of the pattern of synchronization and decoupling of the regions are quite similar. Nonetheless, there are significant di erences regarding the comparison of levels and trajectories across regions, emphasizing the need to intensify e orts to achieve national objectives. This study highlights interest in utilizing the proposed approach for the analysis of the short-run dynamics of environmental performance.
Short-Run Links in Ecological Footprint: A Dynamic Factor Analysis for the EU
(LAND, 2020-12-11) DELGADO-RODRÍGUEZ, MARIA JESÚS; LUCAS-SANTOS, SONIA; CABEZAS-ARES, ALFREDO
The Ecological Footprint (EFP) is a useful indicator for assessing the progress of environmental performance and offers a solid basis for sustainability studies. In this paper, we contribute to the broadening of its possibilities of investigation by measuring the cross-country links in the EFP in global hectares per capita. The modeling framework is based on the dynamic factor analysis to estimate, in the parametric form, an index that provides information about the short-run dynamics of the EFP in the EU. Following this approach, we identify different patterns in the EFP behavior of the European countries during the period of 1962–2017. The results show stronger links across the EFP of the main European countries: France, Austria, Belgium, Germany, Denmark and the U.K. The proposed analysis gives a better understanding of the links behind environmental degradation in the EU and is applicable for the implementation and design of environmental policies.
