Climate Alliance calls on politicians to protect the climate with the Climate Action Call shortly before the EU elections
Stakeholders from across Europe have today launched a call for climate action. "Hundreds of cities across Europe and the world are declaring a climate emergency. They are pushing for an end to fossil fuels and the exclusive use of renewable energy to contribute to climate justice worldwide," explains Thomas Brose, Executive Director of Climate Alliance, co-signatory of the call. "It is time for current and future EU politicians to work together to turn this goal into a European reality."
The Climate Action Call was launched in the run-up to the meeting of heads of state and government on 9 May on the future of Europe and the European elections, which will take place from 23 to 26 May. In parallel, more than 200 mayors are sending an open letter to the European Council and its member states calling for a sustainable and future-proof climate policy. The signatories of the Climate Action Call are calling on current and future EU leaders to take social and municipal calls seriously, take action and make climate action a top priority.
The Climate Action Call lists the following five steps for the new EU Parliament and the Commission as well as all EU member states:
reduce greenhouse gas emissions more quickly by 2030 and achieve greenhouse gas neutrality as quickly as possible.
Focus on the end of fossil fuels and support energy efficiency, renewable energy and emission reductions outside the energy sector.
Ensure fair and equitable structural change. Furthermore, to ensure that the EU provides greater support to developing countries in climate protection and adaptation to climate change.
step up efforts to introduce the circular economy and increase resource efficiency.
protect biodiversity and promote the restoration of ecosystems as a crucial component of climate protection.
Hundreds of cities, companies, investors, scientists, religious communities, sports clubs and civil society organisations from areas ranging from climate protection to human rights and health have taken up the Climate Action Call to bring about profound changes in how we organise our society and economy to keep global warming below 1.5°C.
For more than 25 years, the member municipalities of the Climate Alliance have been working with their indigenous partners in the rainforests to protect the global climate. With 1,700 members from 26 European countries, the Climate Alliance is the world's largest city network dedicated to climate protection and the only one to set specific targets: Each Climate Alliance municipality has committed to reducing its greenhouse gas emissions by ten per cent every five years. As our lifestyle has a direct impact on particularly endangered peoples and places on this planet, the Climate Alliance combines local action with global responsibility. www.klimabuendnis.org
In the run-up to the UN World Human Settlements Summit Habitat III, the German Advisory Council on Global Change (WBGU) points to the major challenges posed by increasing urbanisation. In its report "The Relocation of Humanity: The Transformative Power of Cities", the WBGU emphasises that a brief window of opportunity will open up in the coming decades of urbanisation "to set the course towards sustainability" - see Printed matter 18/9590. In this context, the Council recommends shortening the Habitat conference cycle from 20 to four years. The upcoming Habitat conference will take place from 17 to 20 October in Ecuador. The topic of "urbanisation and transformation" should also become a permanent item on the G20 agenda.
"The report is impressive in view of its wealth of arguments and diverse examples of urbanisation phenomena and the description of their effects. The Association of German Cities feels - not least due to its contributions to the success of the HABITAT III conference in Quito in October 2016 - in complete agreement with the report regarding the central role of cities in mastering the upcoming transformation challenges and utilising their opportunities. The challenges to urban transformation are clearly expressed: the call for a sustainable, globally coded urban development policy is a mandate to the global community and national policies to make cities capable of taking action and to urban societies to utilise this capacity for the benefit of the urban population."
Lord Mayor Dr Eva Lohse President of the Association of German Cities
In its report, the WBGU presents a transformation strategy for the sustainable and "people-oriented design" of urbanisation. Cities play a particularly key role in this, as "the relocation of humanity could become the most powerful process of social change in the 21st century".
The force of the current urbanisation dynamic and its effects are so great that cities, urban societies, governments and international organisations worldwide must face up to this trend. A "business as usual" approach would lead to an unsustainable global urban society if urbanisation policy is not shaped. Only if cities and urban societies become sufficiently capable of acting can they realise their potential for sustainable development: It is in the cities that it will be decided whether the Great Transformation towards sustainability will succeed. This book discusses the conditions for success.
The report identifies five transformative, interlinked fields of action:
Decarbonisation, energy and climate protection,
Mobility and transport,
the structural and spatial design of cities,
Adaptation to climate change and
Poverty reduction and socio-economic disparities.
With regard to climate protection, for example, fossil CO₂ emission sources must be replaced by 2070, writes the WBGU. There would also have to be a "move away from a large part of the current infrastructure patterns" in order to reduce the temperature increase to significantly less than two degrees Celsius.
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.
