Twenty five years ago, the German chemist Michael Braungart developed a new approach to recycling, now called "Cradle to Cradle" or "C2C" after the book, Cradle to Cradle: Remaking the Way We Make Things, which he and the American architect William McDonough published in 2002.

Clean freshwater faces various threats such as increasing demand by population growth, pollution and changes in the hydrological cycle due to climate change.

Many diseases occurring in industrial countries, such as hypertension, type 2 diabetes, stroke or certain cancers are linked to malnutrition. The trouble is that one in two people in Europe is overweight or obese .

Every day cities in Europe discard a useful nutrient-rich resource that could be used to grow crops. Ironically, we treat and process human wastes while we mine non-renewable phosphate and potassium and we consume fossil fuel to make nitrogen fertiliser.

Storm water is a critical consideration in managing urban water , as it influences the risks of flooding. Unfortunately, a global rise in urban population means that water management in urban areas is now under strain.

The German village of Cappel is home to one of the greatest historical music instruments. The ornate baroque organ here is the work of Arp Schnitger, the grand master of German organ construction who built it in around 1680 for Hamburg.

There are 19 countries in the catchment area of Danube River. The extensive use of water resources in that area has not been without consequences on its water quality. Let alone on the riverside’s biodiversity and environment.

The NuOffice in Munich is an office building and one of the showcases of the EU-funded project DIRECTION . The first building phase was completed in 2012, the second and third will be completed in 2014 and 2015.

Much effort has been put into its planning and construction to reach this high-level of sustainability, which makes it the most sustainable newly erected office building worldwide , according to LEEDS standards.

One litre of sea water contains about one billion bacteria.

Making decision that may affect the environment is not that simple. For example, if a EU policy maker believes that biofuels can reduce CO 2 emissions.

Many people in Europe are critical of genetically modified (GM) food, due to safety concerns. A Eurobarometer survey, published in 2010, revealed that the European public tends to be worried on a “mediate level” about GM food , with people in Austria being particularly concerned.

To make a building sustainable, taking into account its climatic conditions is key. No better examples than the three showcase buildings under the EU funded  DIRECTION project.

Coastal areas offer great challenges when balancing the need to protect natural habitats, with the requirement of human and economic activities . Dikes, for example, may not constitute the solutions of the future.

Scientist Peter Freeman is managing a project that is probing the clock and metabolism of plants, called TiMet . Partners to the project include star biologists in the Germany, Spain, Switzerland and the UK, all working to gain better insights into what make plants tick.

Energy efficiency has become a key objective in the current context of increasing energy demand, decreasing resources and global warming. Key to efficient energy savings, however, are users' awareness and behaviour.

Vehicles seats are normally made of polyurethane foam, a thick material that is expensive to recycle and ends up in dumping sites or being incinerated.

How can policymakers change the way people think? This is what the InContext project, funded by the EU, hopes to answer. Leading European research institutions in the fields of transition, behaviour and sustainable development are trying to create a manual for change.
