They're used in the aerospace industry, in ships and wind turbines and even sports equipment: elongated fibers that are more stable than steel and lighter than aluminum. Saertex produces them. Founded by textile engineer Bruno Lammers, the company is now the world market leader in its field and employs about 1,200 workers.

Germany's largest theme park is one of the country's most popular tourist attractions. After a three-week break for alterations, it's now re-opened for winter business, which is especially brisk towards the end of the year. With up to 20,000 visitors a day, security is also a challenge.

The first German city of Münster is withdrawing all of its funds from investments that are harmful to the environment. The divestment underpins the city's existing policies on energy. The money will now be removed from the investment pot of coal companies and pharmaceutical giants.

More than 2,000 individuals, institutions and cities around the world so far have moved their assets to more sustainable, ethical investments. The most well-known representative of the movement is actor Leonardo DiCaprio. The trend is also financially sound, with even rating agencies like Standard & Poor saying the share valuation for coal, oil and gas suppliers is grossly exaggerated; reducing the Earth's temperature by two degrees will mean foregoing these fossil fuel resources. The German city of Münster considers itself part of a global movement. Holger Trzeczak reports on the challenges facing the city as it makes the switch to new, climate-friendly investments.

How will companies be affected by divestment? Can this global movement contribute towards the 2° target? We'll be discussing this with Sascha Müller-Kraenner, director of Deutsche Umwelthilfe (German Environmental Aid), who thinks Germany has been dragging its heels for too long.

Germany's largest theme park is celebrating its 40th anniversary. Each year, millions of people from all over the world pay a visit to Europa Park. As 2015 comes to a close, with the park attracting up to 20,000 visitors a day, the topic of anti-terrorist security poses a major challenge.

Made in Germany takes a look behind the scenes at the park as last minute Christmas preparations are underway. Chef Peter Hagen runs a 2-star restaurant and is preparing for the special dinner and show. The Mack family manage the company and give us an insight into the business of theme parks. Reporter Sonja Schock goes along to see how the winter show costumes are made, how the big wheel is built, and how Christmas decorations are used give the park a magical festive feel.

The German long-distance bus market is booming, but vehicle manufacturers are seeing very little of the profits. The number of buses has risen dramatically since the deregulation of the market two years ago. But market leaders such as Mein Fernbus and Postbus mainly use second-hand vehicles from subcontractors.

So far it's only the decorators who are reaping the benefits. They deck out the old buses with the long-distance giants' corporate design - much more lucrative than buying a new bus which can cost up to €1 m. But that could be set to change, because the old buses are beginning to show their age. Over 20 million customers use the services per year, and there's an increasing demand for comfort. Holger Trzeczak reports on the potential new success story for bus manufacturers.

Refugees keep arriving in Germany only to end up in container shelters and converted airplane hangars. Communities are struggling to cope. Berlin is desperately looking for vacant accommodation.

Taking Berlin as an example, we look at how German cities are attempting to house the refugees. Exact figures for the number of refugees currently in the capital are unavailable, but approximately 40,000 had been registered in the German capital by late October. What procedures do the refugees go through? How are they catered for? Milto Schmidt took a camera team to a makeshift shelter in a gymnasium. He accompanies one district manager on her daily rounds.

The automotive future would seem to be electric. What about the aeronautic future? A German aviation company is working to revolutionize aircraft engines. Engineer Alex Lange is manufacturing gliders powered by electric motors. The motors would hardly be practical for conventional airplane engines, but they can give a hefty boost to gliders.

These quiet motors can lift the glider into the air so it can catch an updraft and continue with no further help. Axel Lange designed the light sports glider with three other engineers at a former military airfield in western Germany. Christian Pricelius visited the company where 25 employees make all the plastic components by hand. They're custom designed for these graceful craft reminiscent of giant dragonflies. Prices start at 165,000 euros.

The refugee crisis and its economic impact

SEAT in Spain is also a Volkswagen subsidiary. Though the company is the pride and joy of Spanish carmaking, it wasn’t faring well for some time. Recently SEAT finally saw its fortunes looking up - but now it’s being knocked back down by the scandal that has engulfed Volkswagen.
