“…DEA has distinct advantages in sustainable development assessments and has been a popular tool in recent years for analyzing eco-efficiency [ 57 ]. We built a slack-based measure (SBM) model that includes undesirable outputs [ 58 ] in order to estimate the annual eco-efficiency of each sector in Gansu’s tourism industry between 1997 and 2016, and using each sector in each year of this period as a decision-making unit, relative efficiency analysis was performed.…”

Eco-efficiency analysis can provide useful information about sustainability in the tourism industry, which has an important role in both global economy recovery and Sustainable Development Goals (SDGs), generating considerable indirect carbon emissions with respect to the supply chain due to its significant connections to other industries. This study, from the perspective of tourism sectors, including tourism hotels, travel agencies, and scenic spots, integrated the environmentally extended input–output analysis (EEIO) and data envelopment analysis (DEA) models to develop a research framework, analyzing the indirect carbon emissions of the tourism supply chain, evaluating eco-efficiency with respect to both direct carbon emissions and total carbon emissions (including direct and indirect parts), and exploring the driving factors of eco-efficiency of tourism sectors using Tobit regression models. This study took Gansu as a case, a province in China characterized by higher carbon intensity, an underdeveloped economy, and rapid tourism growth. The results demonstrate that (1) tourism hotels contribute the most carbon emissions in tourism sectors, especially indirectly due to the supply chain, with carbon emissions mainly resulting from the manufacturing of food and tobacco; (2) the eco-efficiency of tourism sectors in Gansu presents a U-shaped curve, which is consistent with Kuznets’ theory; and (3) energy technology is key to improving the eco-efficiency of tourism sectors. The research results provide a clear path for the reduction of carbon emissions and the improvement of eco-efficiency in Gansu tourism sectors. Against the backdrop of global climate change and the post-COVID-19 era, our research framework and findings provide a reference for similar regions and countries who are in urgent need of rapid tourism development to effect economic recovery.

“…In addition, many others management strategies have been applied to address specific issues such as water scarcity (Payen et al, 2018), energy requirements (Pagani et al, 2016), food waste (March et al, 2019) or climate contribution (Martinsson and Hansson, 2021). Thus, although there is a trend to integrate analytical methodologies such as eco-efficiency and circularity (Rebolledo-Leiva et al, 2022), most studies are focused on specific challenges, overlooking to consider a holistic approach that integrates several of the issues that are related to milk production systems.…”

“…The potential reduction of GHG emissions has also been modeled together with the circularity principle on dairy farms by Rebolledo‐Leiva et al. (2022) using a non‐oriented slack‐based network Data Envelopment Analysis (DEA) model. A similar approach has also been applied to beekeeping by Rebolledo‐Leiva et al.…”

Circular agriculture is vital to achieve a substantial reduction of greenhouse gas (GHG) emissions. Optimizing resources and land use are an essential circularity principle. The objective of this article is to assess the extent to which land optimization can simultaneously reduce GHG emissions and increase production on dairy farms. In addition, we explore the potential reduction of GHG emissions under four different pathways. The empirical application combines the network Data Envelopment Analysis (DEA) with the by‐production approach. This study focuses on a representative sample of Dutch dairy farms over the period of 2010–2019. Our results suggest that farms can simultaneously increase production and reduce GHG emissions by both 5.1%. However, only 0.6% can be attributed to land optimization. The land optimization results show that on average 25.3% of total farm size should be allocated to cropland, which is 6.7% more than the actual land allocation. GHG emissions could be reduced by 11.79% without changing the level of inputs and outputs. This can be achieved by catching up with the mitigation practices of the best performing peers.
