Aviation accounts for two percent of CO2 emissions. This may seem relatively low, but air travel emits 90 percent more CO2 than travelling the same distance by rail. Rail or road can be an alternative for short-haul flights over land, but what about intercontinental and long-distance destinations. So far, research to make flying more sustainable has concentrated on replacing fossil fuel with electric or hydrogen engines. However, a new design – the Flying-V − may change the shape of sustainable flying.

Planet Earth is made up of water for 70 percent, which is why it is called the Blue Planet. Most of the world's water (96 percent) is in the oceans. It is an important source for food, resources, energy, transportation, leisure and living space. The Netherlands seeks to become a partner in developing healthy and productive oceans as part of the solution to global challenges. In the face of population growth and resource scarcity, oceans could contribute to food security, renewable energy and economic development.

Deltas and low-lying coastal areas are constantly faced with threat of erosion and flooding from the sea. Over centuries, the Netherlands has learnt that the key is to work with nature by using the natural power of the sea. The Sand Motor is a prime example of nature-based solutions.

Farmers play a crucial role in global food security, and now Artificial Intelligence (AI) can help them increase productivity with a happier herd. Meet IDA, the Intelligent Dairy Farmer’s Assistant.

Who would have thought coffee grounds could be circular? In fact, they are ideal as a fertile substrate for growing oyster mushrooms. Rotterdam-based rotterzwam collects the coffee grounds from local pubs, large corporations and restaurants. They cultivate the mushrooms and sell the produce to customers in the Rotterdam area.
