With the "GREEN high 3 Roofs | Facades | Courtyards" funding programme for existing buildings, we want to expand the greening of roofs, facades and backyards. In this way, we are supporting the efforts of the people of Cologne to green and thus enhance the value of private house and courtyard areas close to their homes as well as commercial areas.
The grants are awarded as part of the GRÜN hoch 3 programme in accordance with the funding guidelines. By funding green roofs, façades and courtyards in densely populated urban areas, we are helping to improve the local urban climate.
The summer heat load is reduced, dust binding is improved and evaporative cooling is increased. The decentralised temporary storage of rainwater on roofs and in unsealed, green courtyards contributes to the retention of rainwater on site, increases evaporative cooling and reduces the damage caused by heavy rainfall events.
In areas with high levels of pollution, the unsealing and greening of unused rear courtyards and the greening of facades and roofs can not only use rainwater for evaporative cooling during summer heat events, but also achieve additional environmental improvements and building optimisation.
Hamburg, 11. 11. 2020 - By phasing out ten particularly climate-damaging subsidies in the energy, transport and agricultural sectors, Germany can generate up to 46 billion euros in revenue annually.
This is the result of a new study by the "Forum Ökologisch-Soziale Marktwirtschaft" on behalf of Greenpeace. (Study "Ten climate-damaging subsidies in focus" online at: https://bit.ly/2JVu3tq).
A total of almost 100 million tonnes of CO2 equivalents would be saved annually compared to today if the subsidies under consideration were reformed. This is roughly equivalent to the annual greenhouse gas emissions from passenger car traffic in Germany. The study appears in the run-up to the publication of the tax estimate by Federal Finance Minister Olaf Scholz (SPD) announced for Thursday. It shows how the federal government can simultaneously reduce the immense new debt caused by the Corona crisis and make progress on climate protection. "Now the German government can kill two birds with one stone by reducing climate-damaging subsidies: lower CO2 emissions and relieve the budget by billions. In doing so, it eliminates significant disadvantages for climate-friendly industries and can accelerate the shift towards a sustainable, ecologically oriented economy," says Bastian Neuwirth, climate expert at Greenpeace.
A ranking examines the phase-out of ten particularly climate-damaging subsidies in Germany and sorts them according to where the most tax money and CO2 can be saved. The abolition of the tax exemption for kerosene, the withdrawal of tax concessions for electricity generation and the reduction of electricity price exemptions for industry prove to be particularly effective for climate protection and budget restructuring. In arithmetical terms, the German government could save around 73 million tonnes of CO2 equivalents and 18 billion euros of taxpayers' money each year with these measures alone. In the middle of the ranking are the VAT exemption for international flights, the distance allowance, the diesel privilege and the reduced VAT rate on animal products. "Continuing to hand out extra money for climate-damaging economic activity is completely out of step with the times. Each of these climate-damaging subsidies must be overturned as soon as possible," says Neuwirth.
Reduction of subsidies makes German 2030 climate target achievable
The gradual dismantling of the ten subsidies that are particularly harmful to the climate can shorten the Federal Government's delay in achieving its own climate targets: according to the Federal Environment Agency, Germany will emit around 71 million tonnes of CO2 equivalents too much in 2030 with the measures it has adopted so far to achieve the 2030 climate target. A rapid reduction in subsidies can therefore help to remedy this situation. At the international level, Germany and the G7 countries already committed in 2016 to reducing climate-damaging subsidies by 2025.
Meeting the Sustainable Development Goals in the face of the COVID-19 pandemic

The Europe Sustainable Development Report 2020 is the second edition of our independent quantitative report on the progress of the European Union and its member states towards Sustainable Development Goals (SDGs). The report was prepared by teams of independent experts at the Sustainable Development Solutions Network (SDSN) and the Institute for European Environmental Policy (IEEP).

Violet, green, blue and yellow - inside the innovative battery storage systems now available in the Climate quarter of the municipal utility company, will be colourful in the future. The electrolyte, which can store up to ten kilowatt hours of self-produced solar power, changes color depending on the state of charge.
Each of the new storage tanks holds 500 litres of the storage liquid. Redox-flow batteries in the cellars of the seven houses. The developers of the Dortmund-based manufacturer Volterion, a spin-off of the Fraunhofer Institute UMSICHT, installed and filled them themselves in Herne. This is because the climate district is an interesting technical demonstration object for them: Up to now, they have only installed battery storage systems in large-scale projects. In the single-family homes in Sodingen, the battery is only about the size of a two-door wardrobe.
Compared to conventional rechargeable batteries Redox-flow batteries are characterized by high operational reliability and extreme durability. Even a complete discharge does not harm them.
"With the battery, our energy concept of solar system and heat pump is now complete," explains Stephan Becker, project manager at the developer Stadtwerke Herne. "The climate quarter is now entering the home stretch." The final inspection with the future residents is scheduled to take place in about two weeks.
In April of last year, the municipal utility company began construction of the seven modern plus-energy houses. The small car-free model settlement combines the latest storage technology with renewable energy generation. The supply concept varies in individual details. With scientific support, the most efficient combination is to be found after the residents have moved in.
