This study systematically evaluates greenhouse gas (GHG) emissions reporting practices of European airline groups, covering both mandatory and voluntary key performance indicators (KPIs) under evolving regulatory frameworks. By analysing annual and sustainability reports from 16 major airline groups, …

Awareness of climate change and stricter emission regulations have accelerated the search for sustainable energy solutions. A central goal is carbon-neutral energy use, minimizing greenhouse gas emissions while ensuring reliable energy supply. In applications with limited grid access—such as festivals, …

The decarbonisation of the aviation industry requires strict regulation to align with the EU Green Deal, which aims to make the EU the world’s first climate-neutral region by 2050. EU regulations continuously evolve and impact the key performance indicators (KPIs) used to measure progress towards this …

Managing dairy excreta as slurry can result in significant emissions of ammonia (NH3) and greenhouse gases (GHGs) during storage and thereafter. Additionally, slurry often has an imbalanced nitrogen (N) to phosphorus (P) ratio for crop fertilization. While various treatments exist to address emissions …

In the last few years, online shopping has been increasing rapidly. Optimising the sorting processes in E-fulfilment centres, combined with direct parcel delivery from the E-fulfilment centres to the close-by customers has not been widely studied in a quantitative manner. The main objective is to show …

The HARMONY project supports and enables several metropolitan areas to lead a sustainable transition to a low-carbon new mobility era. For city logistics, innovative services and developments can serve as promising solutions to reduce greenhouse gas emissions and energy consumption in metropolitan areas. …

Background Refrigerated containers or 'reefers' are essential for transporting fresh fruit and vegetables in transnational supply chains. By refrigeration, they ensure that food quality is better preserved and food losses are reduced. Countries that produce fresh produce also unlock new markets for export …

In all sectors of the economy, whether in the governmental or private sector, one of the most crucial factors for success is the ability to maintain one’s assets most efficiently and effectively. Finding the best approach for the maintenance of an asset means that it will create the best value possible, …

Decentralised renewable energy production in the form of fuels or electricity can have large scale deployment in future energy systems, but the feasibility needs to be assessed. The novelty of this paper is in the design and implementation of a mixed integer linear programming optimisation model to minimise …

The majority of Dutch peatlands are drained and used intensively as grasslands for dairy farming. This delivers high productivity but causes severe damage to the provisioning of ecosystem services. Peatland rewetting is the best way to reverse the damage, but high water levels do not fit with intensive …
