Four different tickets to get from A to B? Registered with five services for car sharing, e-scooters or rental bikes? That's annoying. The Greens want to simplify mobility and link up rail, public transport, cycling and the car. In the city and in the country. This is possible with the green MobilPass.
This good concept has been around for a while. Finally, a party is including it in its election manifesto.
The Federal Environment Agency's publication "Urban Mining" was published in July 2017 and explains the possibilities of extracting raw materials in urban areas, for example from buildings, infrastructure and durable consumer and capital goods. While waste management is essentially concerned with the volume of waste, urban mining looks at the total stock of durable goods. The aim is to forecast future material flows as early as possible and to develop and establish the best possible recycling routes on this basis.
According to the Federal Environment Agency, five key questions on urban mining need to be answered at an early stage so that the potential of this concept can be strategically realised. Questions were identified regarding the location, nature and release of anthropogenic deposits, the players involved and the technical, logistical and organisational requirements.
The brochure is intended to convey an understanding of urban mining and to encourage the pursuit of this strategic approach. The Federal Environment Agency is striving for a strategic and interdisciplinary approach to urban mining.

An important milestone in the Federal Environment Ministry's international nature conservation and climate protection policy has been reached. The so-called "Bonn Challenge" initiated by Germany to rebuild forests has succeeded in getting countries to pledge a total of 150 million hectares. The goal was reached yesterday at the first Bonn Challenge regional conference for Asia in Palembang, Indonesia. There, Bangladesh, Mongolia, Pakistan and Sri Lanka announced further contributions to forest reconstruction. In Bonn in 2011, on Germany's initiative, numerous countries agreed to restore 150 million hectares of destroyed forests worldwide by 2020.
Environment State Secretary Jochen Flasbarth, who attended the conference on behalf of Germany, congratulated Alex Noerdin, Governor of South Sumatra Province and host of the regional conference: "The Bonn Challenge has created incredible global momentum for forest restoration. When we launched the Bonn Challenge in 2011, no one could have imagined that we would reach the 150 million hectare target three years ahead of schedule. The encouragement that countries in the region here in Palembang have given to the Bonn Challenge, and that they are also using it for their national initiatives, shows that in 2011 we kicked off a groundbreaking development for global forest restoration with the Bonn Challenge."

BN - Is the roof of my house or company building suitable for a photovoltaic system or a solar thermal system? This question can now be answered quickly and conveniently online with the help of the new solar roof cadastre of the city of Bonn. In a building-specific map display, a coloured marker indicates whether and to what extent a roof is suitable for energy generation by means of solar power. Step by step, further information, for example on the economic efficiency, can be retrieved via a yield calculator.
The suitability of the roofs of all 129,000 buildings in the city for solar energy generation was recalculated using the latest, improved data. For this purpose, elevation grid data was used, which was determined by the district government of Cologne by means of laser scanning in spring 2016. Compared to the previous version from 2010, the new Bonn solar roof cadastre features, among other things, a fourfold higher resolution and a more differentiated designation of the roof areas.
The suitability of the roof surfaces for electricity generation via photovoltaic systems as well as for domestic water heating and, for the first time, also for supporting building heating via solar thermal collectors was calculated. The calculations also took into account the current changes in the framework conditions with regard to feed-in tariffs and self-consumption of generated solar power.
How the application works
In the city map, the installable system size and many additional data such as yields and savings potentials can be displayed for each building. In a newly developed yield calculator, costs and yields can be calculated and compared by entering additional user-specific information such as electricity consumption or household size. In this way, every owner can quickly gain an overview of the suitability of his or her building for the use of solar energy. Detailed instructions are available at www.bonn.de/...solardachkataster.php.
The City of Bonn points out that the information from the solar roof cadastre is an initial non-binding assessment. Essential prerequisites for a decision to build a system, such as the condition of the roof or the static suitability, can only be clarified by suitable specialist companies or qualified consulting organisations. Information on this can be found on the website of the solar roof register.
Bonn roofs have potential
According to the potential analysis of the solar roof cadastre, 6,800,000 square metres in Bonn are suitable for solar power generation. This corresponds to about the size of 950 football fields. Approximately 800,000 megawatt hours of electricity could be generated on this area. This could cover about 50 percent of the total electricity consumption in Bonn. For solar thermal energy, the result of the potential analysis shows 88,461 buildings in Bonn that could be used for this form of energy generation. This corresponds to about 70 percent of the buildings in Bonn.
