This paper aims to inform policy and research in the domain of tourism and hospitality on the role of innovation and entrepreneurship. The paper applies the review research methodology to collate, comprehend, and synthesise 139 papers selected through a standard procedure. Our findings show that innovation drives growth and value in new tourism and hospitality firms. The study examines external factors, particularly government policies, influencing industry stakeholders’ entrepreneurial orientation and the macroeconomic environment affecting entrepreneurial activities. It also highlights the importance of social entrepreneurship in industry innovation and sustainability. This article emphasises the importance of innovation and entrepreneurship in tourism and hospitality growth, value creation, and social and environmental issues.

There has been a substantial amount of research done on air pollution, both in terms of its history and its state at the present time. On the other hand, the ever–changing influence of climatic variables such as sun hour, air pressure, and wind speed has gotten just a small portion of the attention. This divide becomes even more apparent when one considers the ongoing conflicts that are taking place between Russia and Ukraine as well as the current state of the environment's response to climate change. In order to bridge this research gap, the goal of this study is to explore the ways in which climatological factors impact air quality, especially levels of PM2.5 and ozone, in a range of cities situated in India, during 2020–2021. Studies conducted over brief and extended periods of time have made it abundantly evident that sun hour, wind speed, and humidity have an impact on ozone levels. The study also sheds light on prospective policies that may be implemented in the future, such as those relating to carbon emission and particulate pollution such as PM2.5, in order to successfully battle the negative impacts that these variables have on the environment.

This research presents an in-depth investigation into the dynamic correlation between geopolitical conflicts and carbon markets utilizing the Time-Varying Parameter Vector Autoregression (TVP-VAR) technique. The analysis focuses on the interconnectedness between the Geopolitical Risk Index Daily (GPRD) and vital carbon pricing instruments, specifically the Intercontinental Exchange Endex European Union Allowance (ECEFDC), KraneShares California Carbon Allowance Strat ETF (KCCAK), Shanghai Environment and Energy Exchange China Emission Allowances Online Transactions (SAXCEA), and S&P Global Ex-Japan LargeMidCap Carbon Efficient Index (SPGJ). The daily fluctuations were traced from May 2021 to July 2023. The analysis is divided into short- and long-term connectedness, with particular emphasis on the impact of the Russia-Ukraine conflict on the GPRD's spillover on carbon markets. The short-term connectedness (1–5 days) between GPRD and ECEFDC shows variability, fluctuating between 10% and 40%. Conversely, long-term connectedness exhibited a significant increase during the conflict, peaking at approximately 34% by mid-2022. The analysis of the Total Dynamic Connectedness (TCI) between the GPRD and the KCCAK indicates comparable magnitudes, although with minor initial discrepancies. The short-term connectedness of GPRD and KCCAK decreases from its peak of approximately 10% to approximately 1%. Conversely, long-term connectedness varies between approximately 32% and 2% from May 2022 onwards. The long-term connectedness between GPRD and SAXCEA revealed variable patterns, peaking at around 18% at the beginning of the sample period and rapidly reducing to around 1% within two months. The analysis of the connectedness between GPRD and the SPG) identifies intense fluctuations in both TCI and long-term connectedness. After an initial increase and decrease, these patterns rebound and experience another increase. This research provides significant insights into the complex dynamics of geopolitical conflicts and carbon markets, particularly the impact of the Russia-Ukraine conflict on carbon market behavior.

This study examines the commitments made in the Conference of the Parties (COP) summits, COP 3 (Kyoto), COP 15 (Copenhagen), COP 21 (Paris), and COP 28 (Dubai). It critically investigates global climate initiatives concerning sustainability and environmental justice. While these summits have played a pivotal role in shaping international climate diplomacy, persistent gaps remain between pledges and their implementation — particularly in mobilising adequate financial and technical support for developing countries. Drawing on Political Ecology Theory and Environmental Justice Theory, the study examines how structural asymmetries and historical inequalities may continue to shape global climate governance. We highlight how, in some instances, well-intentioned environmental leadership may risk overlooking equity and inclusion, particularly when developing nations are expected to meet ambitious climate standards without proportionate support. At the same time, the paper acknowledges critical progress made through COP processes — such as the Paris Agreement’s recognition of common but differentiated responsibilities (CBDRs) and the establishment of the Loss and Damage Fund at COP 27 and COP 28. Policy recommendations include the institutionalisation of independent climate finance audits and the integration of justice-centred accountability frameworks into global climate policy. By situating contemporary climate negotiations within a historical and justice-based framework, the paper calls for more inclusive, transparent, and accountable COP mechanisms. This includes amplifying the voices and needs of those most vulnerable to climate change, particularly in the Global South.
