District heating can provide an efficient solution to heating urban buildings, while waste-water treatment plants represent a potential source of renewable energy. This study evaluated the potential impacts of using waste-water heat to supply district heating systems and applied it to the situation in Serbia. The researchers say that widespread use of this approach could improve efficiency and reduce carbon dioxide emissions, and that the methodology could be applied elsewhere. Click here to read more

Agricultural packaging impacts the environmental performance of food. This study compares the carbon footprint (CF), of two commonly used containers for international road transport of fruit and vegetables. The study assesses corrugated cardboard boxes (CCB) and polypropylene foldable boxes (PPB) in two different sizes, for a cradle-to-grave assessment of their environmental performance when used to transport tomatoes from Spain to Germany.

The key deliverable of the EU-Japan Summit was the Green Alliance – the first of its kind. The Alliance has a very strong environmental dimension reflecting the overall spirit of the European Green Deal and DG ENV top priorities. As such, it includes a joint commitment to the post-2020 global biodiversity framework, circular economy, sustainable supply chains and the global plastics agreement. The intention is to deepen green cooperation with Japan, to make it more visible and promote the green agenda together at a global level.
Transitioning energy production from a dependence upon fossil fuels to renewable energy sources (RESs) promises to reduce environmental impacts while aiding economic growth. A study explores the benefits of implementing the Italian government’s renewable energy plan, which includes installing photovoltaic (PV), hydroelectric, wind, and geothermal infrastructure from now to 2040.

Frozen freshwater lakes provide ice to support human transportation, refrigeration, food harvest and recreation. This ice also influences key environmental factors; crucially, it minimises lake evaporation rates, moderates summer water temperatures and curtails toxic algal blooms. However, freshwater-lake ice cover is decreasing under climate change. A study estimates how many lakes in the Northern Hemisphere will permanently lose ice cover within this century, and identifies those most at risk of becoming ice-free. Click here to read more
Researchers have evaluated the EU’s environmental risk assessment tool for antifouling paint used on leisure boats. Currently, product approval applications can report biocide release rates that have been ‘corrected’ to account for potential overestimation. However, field observations in Swedish waters suggest that these reductions are not accurate and — in order to protect marine ecosystems — should not be used. Click here to read more
Sustainable soil is a foundation of environmental health, with soil offering a multitude of ecosystem services including climate mitigation and adaption, biodiversity, agriculture (food security) and nutrient cycling. This study offers a new framework for monitoring synergies and trade-offs of soil functions across Europe. Click here to read more
Restoring global ecosystems is an urgent priority in efforts to conserve biodiversity and stabilise our planet’s climate. However, the costs and outcomes of ecosystem restoration differ markedly by location and habitat type. A recent study has developed a multi-criteria cost-benefit approach to identify priority areas for optimal restoration of terrestrial cropland and pastureland back to natural ecosystems, considering the outcomes of biodiversity conservation, climate mitigation and cost minimisation.

Food security is a growing concern as crop yields are threatened by increasing climatic variability — periods of excessively hot weather, or heatwaves, specifically. This study examines the crop diversity of the sweet potato (Ipomoea batatas) to understand which genetic variants flourish in response to climatic stress and to identify the crop traits that aid this success.

Approximately 88 megatonnes (Mt) of food are wasted every year in the European Union, causing 186 metric tons (Mt) carbon dioxide equivalent (CO2-eq) — a universal measure for all greenhouse gases. The impact of food waste on the climate, acidification and eutrophication is around 15–16% of the environmental impact of the entire food chain. In developed countries, food waste is high at the point of consumption— so significantly reducing food losses would require a food-waste reduction in households and the food-services sector.
While cities worldwide are expanding so is the significant carbon dioxide footprint of urban transport. Consequently, there is an urgent need for sustainable urban mobility solutions. A thorough analysis of the variables and dynamics of urban mobility in cities can aid in planning sustainable mobility policy. This study used a new system of classification by type (typologisation) relevant to urban mobility in global cities, with data from 331 cities in 124 countries covering 40% of the global urban population (as of 2016).
How can we grow more crops without taking too much water away from freshwater ecosystems for irrigation? A new study indicates that it is possible to double crop production by 2050 without exceeding set limits for water extraction if more crops are grown in regions with higher rainfall and with corresponding shifts in international trade and agricultural management. However, without appropriate safeguards, and if we follow the current business-as-usual scenario, this could come at the ecological cost of converting natural land and forest into cropland. This research provides a ‘first-step’ in analysing potential trade-offs in the global food-trade-water nexus.
The most comprehensive glacier assessment yet reveals that glacier melt was responsible for 27 mm of sea level rise between 1961 and 2016. Ice loss from glaciers is now the second biggest contributor to rising sea levels after warming water. If glaciers continue to melt at current rates, most — including many in central Asia, central Europe, western Canada and the USA — will vanish during the second half of this century.
Data storage has become an essential part of digital work, but it comes at a price. In 2015, data centres and server rooms already accounted for an estimated 2.25% of EU energy consumption, and their manufacture, cooling and end-of-life also have environmental impacts.
