In the past few decades, the tourism and hospitality sector has not only witnessed significant growth but also contributed tremendously to economic progress with lease inputs. This fastest-growing sector creates a number of environmental challenges, especially in emerging markets where the carbon footprint of tourism constitutes a large share of CO2 emissions. This study explores the effect of international tourism, renewable energy consumption (REN), and eco-friendly technology on CO2 emissions in emerging markets. The AMG, Driscoll-Kraay and Prais-Winsten regression confirm the adverse effects of international tourism on the environment, whereas technological innovation and REN mitigate CO2 emissions. Furthermore, economic growth and population increase CO2 emissions, while foreign direct investment (FDI) reduces CO2 emissions. Although the direct effect of technological innovation is insignificant, the indirect impact is negative and statistically significant; confirming the moderating effect of eco-friendly technology on the relationship between international tourism and CO2 emissions. The MMQR results suggest that REN reduces CO2 emissions across all quantiles. On the other hand, technological innovation significantly reduces CO2 emissions in lower and median quantiles, whereas international tourism and economic growth reduce CO2 emissions across all quantiles. Various directions of causality were reported alongside relevant policy directions. [ABSTRACT FROM AUTHOR]

Tourism contributes approximately one‐fifth to total global employment. However, growth in tourism can promote an increase in transportation, energy consumption, natural resource exploration, and consequential ecological distortions. This study applies a battery of second‐generation econometric techniques to investigate the influence of tourism development and natural resource on a comprehensive environmental indicator; the ecological footprint (EF), in the ten most visited destinations. The findings show that tourism receipts have an increasing effect on EF, while tourism arrivals have a reducing effect on EF. The country‐wise results reveal that tourism receipts increase the EF in China, Italy, Spain, and the UK, while the reverse holds true for France, Germany, Thailand, Turkey, Mexico, and the US. The influence of natural resource on the EF is mixed. Natural resource increases the EF in China, France, Germany, Spain, and the UK. A feedback causality exists among EF, natural resource, and tourism development. Policy directions are discussed. [ABSTRACT FROM AUTHOR]

Uncertainty is an overarching aspect of life that is particularly pertinent to the present COVID-19 pandemic crisis; as seen by the pandemic's rapid worldwide spread, the nature and level of uncertainty have possibly increased due to the possible disconnects across national borders. The entire economy, especially the tourism industry, has been dramatically impacted by COVID-19. In the current study, we explore the impact of economic policy uncertainty (EPU) and pandemic uncertainty (PU) on inbound international tourism by using data gathered from Italy, Spain, and the United States for the years 1995–2021. Using the Quantile on Quantile (QQ) approach, the study confirms that EPU and PU negatively affected inbound tourism in all states. Wavelet-based Granger causality further reveals bi-directional causality running from EPU to inbound tourism and unidirectional causality from PU to inbound tourism in the long run. The overall findings show that COVID-19 has had a strong negative effect on tourism. So resilient skills are required to restore a sustainable tourism industry. [ABSTRACT FROM AUTHOR]
