    Drivers of carbon emissions in G7 economies: Evidence on energy use, globalisation, urbanisation, industrialisation and innovation
    (Elsevier Ltd, 2026-08-26) Weerasinghe, L; Vithanage, N; Rupasinghe, D; Keesha, C; Jayathilaka, R
    Rising CO2 emissions remain a major sustainability challenge, particularly in advanced economies that account for a considerable share of historical emissions. This study examines the key determinants of CO₂ emissions in G7 countries by jointly considering globalisation, energy consumption, urbanisation, industrialisation, and technological innovation. Using a balanced panel dataset for Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States over the period 1997–2023, the analysis applies panel regression techniques and country-specific multiple linear regressions to capture both common effects and heterogeneity across economies. The results indicate that energy consumption is a robust driver of CO₂ emissions across the G7. Technological innovation contributes to emission reduction at the panel level; however, its effect becomes statistically insignificant in country-specific estimations, reflecting cross-country differences in innovation structures and policy environments. Globalisation significantly increases emissions in Canada, while its influence is negligible elsewhere. Urbanisation shows a mitigating effect only in the United States, and industrialisation increases emissions in Canada and Italy but reduces emissions in Japan. Overall, the findings highlight that decarbonisation strategies in advanced economies should prioritise the transition to clean energy while strengthening innovation-oriented climate policies tailored to country-specific contexts.

    Economic and trade determinants of carbon emissions in the American region
    (Elsevier, 2025-06) Methmini, D; Dharmapriya, N; Edirisinghe, S; Gunawardena, V; Jayathilaka, R; Wickramaarachchi, C; Dharmasena, T
    Balancing economic growth with sustainability has been a significant challenge over the past decades, largely due to the environmental damage caused by carbon emissions. This study investigates the relationship between energy consumption, gross domestic product (GDP), and trade openness and their impact on carbon emissions in 28 countries in the American region from 2000 to 2022. Using a multiple linear regression model for country-level analysis, the findings reveal diverse trends across the region. For instance, countries such as Antigua and Barbuda, Bolivia, Brazil, Chile, and Guatemala demonstrate a strong link between economic growth and increased carbon emissions. In contrast, developed nations such as the United States and Canada show signs of decoupling GDP growth from emissions, supporting the Environmental Kuznets Curve hypothesis, which suggests that higher income levels lead to reduced environmental degradation. The study highlights the importance of tailored, country-specific strategies to reduce emissions while promoting sustainable economic growth. A thorough understanding of the complex relationships between gross domestic product, energy consumption, trade openness, and carbon emissions will enable policymakers to devise strategies that balance ecological sustainability with socio-economic objectives.
