ABSTRACT Climate change, driven by greenhouse gas (GHG) emissions, causes extreme weather events, impacting ecosystems, biodiversity, population health, and the economy. Predicting GHG emissions is crucial for mitigating these impacts planning sustainable policies. This research proposes a novel machine learning model forecasting. Our model, Meta-Learning Applied to Multivariate Single-Step Fusion Model, utilizes historical from Brazil over past 60 years predict CO2 CH4 emissions. Additionally, employs unique combination of two techniques in time series forecasting: (i) each substance individually extracted trained based on specific decision task, then integrated into same feature space; (ii) allows learn prediction tasks, leading better generalization. was compared with state-of-the-art models using dataset.

Abstract This study analyzes non-hydroelectric renewable capacity across 27 European countries from 2000 to 2020, using advanced econometric techniques like the Dumitrescu and Hurlin panel Granger non-causality method, Panel Autoregressive Distributed Lag Quantile estimations. investigation reveals complex relationships extending beyond immediate variables. These relationships, rooted in pairwise causalities broader interactions, underpin observed phenomena. Causality tests show that achieving is a long-term endeavor, emphasizing persistent policy approaches for effective energy transition. Three key variables emerge as potent drivers: maintaining an environment conducive economic freedom, fostering financial development, driving patents’ research development. play pivotal role expansion. Additionally, findings of this empirical spotlight political orientations. Leftist governments have lagged prioritizing transition, prompting questions about neglecting environmental concerns necessitating comprehensive reform. In essence, offers novel insights into deployment. By unraveling policies, identifying variables, provides nuanced perspective line with sustainable transition urgency. As global ecological imperatives heighten, our work guides informed decisions greener future.

Os recursos energéticos desempenham um papel fundamental no desenvolvimento econômico e social das nações. Este trabalho teve como objetivo analisar o panorama energético brasileiro período de 2014 a 2023, utilizando dados da Empresa Pesquisa Energética (EPE). Em produção energia primária alcançou 391,0 Mtep, enquanto oferta interna consumo final foram 313,9 Mtep 282,5 respetivamente. Esses valores representam crescimento 42,9%, 2,5% 6,7% ao longo do analisado, nesta ordem. A matriz energética brasileira manteve uma participação significativa fontes renováveis, correspondendo 49,1%, com predominância petróleo derivados, produtos cana-de-açúcar hidráulica. Já elétrica nacional atingiu 89,2% destaque para geração hídrica, eólica solar em 2023. No contexto global, demonstrou grau renovabilidade aproximadamente três vezes superior à mundial.
