  5. 5. 2. A vision for the climate in Aarhus The vision for the climate in the City of Aarhus has been drawn up on the basis of the political goal of reaching CO2 neutrality in 2030. The vision states: “In order to develop a sustainable city, Aarhus takes the lead in the effort to tackle climate change by means of initiatives involving buildings and physical structures as well as citizens’ behaviour. The City of Aarhus will sweep before its own door, carry out demonstration projects and influence national legislation”. The vision is carried out through concrete efforts to tackle climate change – building on three principles: • Holistic thinking • Synergy between different players • Long-term perspective 5
  6. 6. 3. The City of Aarhus has got plans for the climate The climate plan for the City of Aarhus consists of several generations of climate plans reaching towards 2030. The plans each have a two year per- spective in order to guarantee progress, adjustment and evaluation. The climate plans are versatile, and they prioritise and coordinate across the municipal organization, the business community and educational institutions. ”Climate change is a fact – globally and locally – no matter how much we try to pull the emergency brake”, says Claus Nickelsen, director of the City of Aarhus’ Climate Secre- tariat, - “But we can work towards making sure that the consequences of climate change do not become even worse. Innovation, new forms of cooperation, new technology, collective solutions and climate friendly habits are all key words when we want to reach the goal of CO2 neutrality in Aarhus. To reach our goals the climate plans represent an essential tool.” 6
  7. 7. Carbon footprint in the workplace In 2007, the CO2 emission from the City of Aarhus as a business organization was approx. 110,000 tonnes. This corresponds to about 5 % of the total emission and to an 4. CO2 emission is monitored every year average of 4.7 tonnes pr. full time employee. This is why the City of Aarhus is also focusing on reducing CO2 emis- sion from the City of Aarhus as a business organization. Aarhus was the first city in Denmark to monitor and map its total CO2 E.g.: emission. Furthermore, the City of Aarhus has participated in the develop- • Energy management system in the Department of Techni- ment of an instrument – the CO2 calculator – that other cities now use to cal Services and Environment: Implementation of certified monitor their CO2 emission. energy management and exchange of experience with the other departments.

Also the citizens of Aarhus are capable recyclers. Every year the six projects are carried out based on these four cornerstones. recycling centres in Aarhus count 1.2 mil. visits, 67 % of all waste is recycled and 31 % is utilized for incineration and heating supply. 9
  10. 10. The light rail is on track The City of Aarhus wants to promote sustainable forms of transporta- tion. In January 2009, the Danish National Parliament reached a trans- port agreement earmarking DKK 500 mil. to the first stage of the light rail project in Aarhus. As early as in 2000, the City Council decided that the solution of the city’s traffic-related problems should come from prioritising busses and other forms of public transporta- tion, especially transportation by rail. Since then, the municipalities of eastern Jutland have formed a cooperation to establish a “Vision for the light rail”. The light rail will offer commuters a very fast, sustainable and comfortable alternative to the car. When the light rail takes its maiden trip in 2015 the rails will have been interlinked with the “Odder Rail- road” south of the city and the “Grenå Railroad” to the north – with new trains to follow on these railroads. New rails will be built – stretching from the city centre and 12 kilome- tres out via the suburbs of Skejby, Lisbjerg and Lystrup in the northern part of Aarhus. With an expected “park and ride” facility in connection with both the northern high way and the light rail, the commuters will benefit from fast and efficient public transportation while avoiding parking problems. Additionally, the electric light rail in the urban area of Aarhus makes room for urban renewal, followed by enhanced quality of life as well as less noise and pollution in the streets. Studies show that in order for citizens to choose public transportation, it is very impor- tant to have frequent departures. This is why the City of Aarhus is planning a light rail with up to 12 departures an hour. With this project, the City of Aarhus is well on the way to creating an efficient public transport system, which will benefit both the city and the surrounding areas. 10
  11. 11. Aarhus Cycling City The City of Aarhus is a so-called Bicycle City and bike riders are a well es- tablished part of the street traffic in Aarhus. The city’s 250 kilometres of bicycle lanes contribute to making it appealing to go by bike. The City Council has passed a bicycle action plan of 65 million DKK which will make con- ditions for the local cyclists even better. Soon we will see more and better bicycle lanes, bicycle barometers and bicycle parking facilities. Other than that, the City of Aarhus has developed a new device that will be set up in certain intersections to warn cyclists of potential accidents involving trucks making right turns. Environmentally friendly vehicles in the streets The dedication to environmentally friendly vehicles is a reality. Cutting back on car traffic is possibly one of the most difficult challenges in the effort to tackle climate change. That said the electric car shows particular potential as the most CO2 friendly transportation technology to challenge conventional petrol and diesel fuelled cars. That is why the City of Aarhus will work to promote environmentally friendly vehicles in the streets in cooperation with other companies. The goal is to introduce electric cars, electric bicycles and other environmentally friendly vehicles in the municipal organisation as well as develop principles for and trial versions of charging stations for electric cars in the urban area of Aarhus. 11

  13. 13. The forests are growing The City of Aarhus has ambitious plans for the local forests and the inten- tion is to increase the absorption of CO2 in nature zones. By 2030 the for- est area in the City of Aarhus will have doubled. Well kept forests are among the finest characteristics of Aarhus. This is underlined by the fact that the forests of Aarhus are estimated to have more than three mil. visitors every year. The forests benefit the city, the citizens and the climate. And both new and existing forests play an important part when it comes to environmental protection and the efforts to tackle climate change. Every hectare of new forest absorbs around 14 tonnes of CO2 annually. Furthermore, the forests provide maximum protection of our drinking water. In the future more wetlands will be established in the existing forests, which generates more storage of CO2 as well as buffer zones for an increase in rainfall. Ultimately, new forests create high- quality nature zones in the local area. The Municipal Plan 2009 for the City of Aarhus includes a plan to double the existing for- The amount of CO2 present in the atmosphere can be reduced in two est area by 2030 – corresponding to 3200 hectares of new forest. Elements of the plan are ways: By emitting less CO2 and by absorbing CO2 from the atmosphere. already being launched with the allocation of DKK 38 mil. over the next three years to plant By means of photosynthesis trees absorb CO2 from the atmosphere and bind the carbon in the biomass of the forest. CO2 absorption is continu- 320 hectares of new forest. The new forests will be both public and private forests because ous during the growth period of the tree – up to 90 years the plan entails attractive subsidy schemes promoting private afforestation. 13
  14. 14. 6. Public participation Citizens and employees play a part It is important to involve the citizens of Aarhus in the effort to combat cli- mate change, to offer them inspiration so that they implement new climate friendly habits in general and start renovating their houses in an energy efficient manner. The citizens of Aarhus are the source of a large part of the CO2 emission in Aarhus. Consequently, the citizens must be offered solutions on how to make a climate friendly life easier. E.g. there is great potential in the new technical solutions making it easier to monitor one’s own energy consumption. Also, it is possible to generate considerable reductions by purchasing low energy household electrical appliances and by carrying out energy renovation on private houses. Campaigns and social media contribute to mak- ing citizens aware of the climate challenges. And ultimately, by boosting awareness of climate issues among local school children we make sure that future adults are equipped to continue the job of tackling climate change. These are all themes that the City of Aarhus has a dedicated focus on. The City’s climate web site - www.CO2030.dk - is continuously developed to offer citizens the knowledge and the tools required to be a climate friendly home owner, consumer, child or adult in the City of Aarhus. 14
  15. 15. Energy efficient houses help the climate – and your wallet Both the climate and your wallet benefit from an energy efficient house. The City of Aarhus assists in the process by means of measuring heat loss from houses, subsidy schemes and climate partnerships. In the spring of 2009 the first thermographic overflight of Aarhus was performed to measure the heat loss from houses and buildings. The overflight provided a clear illus- tration of the fact that much can be done by reducing energy consumption in the houses and buildings of the city. Therefore, the City of Aarhus will launch a service where citizens and companies can see how much excess heat their buildings emit – on the basis of thermographic overflights. The service is available from the end of 2010. Accompanied by a climate partnership with the Danish Ministry of Climate and Energy and their online energy guide for houses, the citizens of Aarhus will be provided with knowledge of where and how to start energy renovation of their houses. Other than that, the City’s department for Waste and Heat offers the citizens a subsidy scheme encouraging energy renovation of their houses. This popular cash injection makes it easier to be an energy friendly home owner in Aarhus. 15
  16. 16. Climate ambassadors are front-runners The City of Aarhus has got 30.000 employees. The goal is to make climate a key issue so that all employees can develop new climate friendly habits and at the same time motivate others. In order to intensify the effort towards the City’s own employees a group of municipal climate ambassadors have been appointed. The climate ambassadors are all active when it comes to involving their colleagues and the entire work place in the efforts to tackle cli- mate change – e.g. by introducing AutoPowerOff plug banks at the work place or to create awareness of the City’s goal to become CO2 neutral in 2030. One of the climate ambassadors is Jim, age 40, it consultant in the Mayor’s Department. He says: ”The climate issue has to be top priority in the media and each of us have to show the way. If we want to be able to do something about the challenges we are facing, the unpopular decisions have to be made at a central level. There is a need for more stick than carrot!” Jim, klimaambassadør 16
  17. 17. 7. Cooperation with businesses and schools A climate lab with innovative prospects The City of Aarhus wants to support industrial development in connection with climate issues. The possibility of creating new solutions and technologies to the benefit of both citizens and companies in Aarhus is emphasised by the fact that the City of Aarhus aspires to enter into climate partnerships with relevant players. The City of Aarhus is also planning to help companies with energy reduction as well as participate in the develop- ment of an innovation centre for energy. The City of Aarhus’ goal to become CO2 neutral in 2030 offers the city great opportuni- ties of becoming a fascinating demonstration city where companies can test and experi- ence new energy and climate solutions. Overall, the dialogue with the business world, research and educational institutions is crucial if the city wants to achieve its goals of CO2 neutrality in 2030. Both in order to reduce emissions and strengthen the industrial development and research efforts, but also to kick off innovative climate-related projects. Therefore we need to boost cooperation between the Central Denmark Region, local knowledge institutions, companies, consultants and the City of Aarhus. 17
  18. 18. Climate partnerships accelerate cooperation In November 2009 the City of Aarhus entered into a climate partnership with DONG Energy and an agreement with NRGi is just around the corner. More climate partnerships are on the way. The climate partnership with NRGi is expected to launch a series of initiatives, e.g. cooperation within the framework of communication and public participation, charging stations for hybrid cars and electric cars, energy monitors for municipal buildings as well as knowledge sharing on several other matters. The partnership with DONG Energy will become very important for a CO2 neutral heating supply. Among other things, the goal of this partnership is to convert one of the facilities at the Studstrup Power Plant into a biomass generated heating system. This means that a significant part of the district heat- ing in the City of Aarhus will eventually be based solely on CO2 neutral fuels. Anders Eldrup, group managing director of DONG Energy, says: ”It is a positive and strong signal that the second largest city in Denmark wants to be so specific about its ambitious climate strategy in cooperation with DONG Energy. The City of Aarhus has set the bar high and we look forward to a profitable collaboration”. Managing Director Søren Sørensen of NRGi comments on the climate partnership: “The agreement can (…) contribute to significant CO2 reduction both for the City of Aarhus and for the climate in general”. 18
  19. 19. The Climate Secreatriat at Aarhus University An innovation centre for energy and energy technology Søren Sørensen, Managing Director at NRGi A wide circle of players across industry, education, research and development as well as public authorities – including the City of Aarhus – want to establish a new innovation centre in the Aarhus Docklands – an international beacon of technology: Navitas Park. Navitas Park has got two energy-related objectives: • That the building attains classification as a Low Energy Class 1 construction which means that the energy consumption of operations cannot be more than 50 % of the standard building code • That students, teachers, researchers and entrepreneurs are actively involved in reduc- ing the energy consumption determined by the users’ behaviour. It is planned that the building itself will have the characteristics of an energy lab where the building components and installations are directly applicable in daily education, Keld Laursen, Associate Rector at the Aarhus School of Engineering development and research. 19
  20. 20. A climate package for inspiration There is great potential for saving energy in manufacturing companies as well as other kinds of companies. A barrier for reducing energy consumption is often a lack of over- view of the different methods for energy reduction as well as a lack of in depth mapping of the energy consumption in the individual company. Therefore, the City of Aarhus is in- troducing a climate package to offer inspiration to companies as to how they can reduce their energy consumption. The climate package will consist of different tools and options, which will support the process of identifying and implementing efforts to reduce energy consumption. The Climate Baton generates good ideas The most important asset of a company is its employees. The launch of a ”Climate Baton” will create focus on energy habits, and the employees’ many ideas for tackling cli- mate change will be the starting point for knowledge sharing. The Climate Baton started at The Danish Broadcasting Corporation in October 2009 and during the following year the baton will visit 12 private and public companies. On the web site, www.CO2030.dk, the City of Aarhus tells the stories of energy-related experiences and know-how collected from the companies – for the inspiration of others. 20
  21. 21. This is how Aarhus adapts to climate change 8. Climate adaptation • Making room for controlled flooding – e.g. by establishing wetlands in the river valleys The city must be protected from flooding • High water locks at the mouths of the Aarhus and Egaa Streams Among other things, climate change causes more heavy rain fall and a higher water level • Less maintenance of the streams. This causes water to in the Bay of Aarhus. In many cases sewers and sewage treatment plants do not have the be retained in the streams and the areas surrounding the capacity to handle such large amounts of water – risking both flooding and water pollu- streams tion. Therefore, the effort is positioned on several fronts. • Mapping areas in danger of being flooded Climate change also means periods of increased flow of water in the streams, more water in the lakes and periods of almost dried-up streams. A higher water level in the Bay • Establishing early warning systems in case of flood risk of Aarhus could lead to flooding of Aarhus city centre along the Aarhus Stream running through the city. • Making the city’s water an integrated part of urban develop- Aarhus is also close to the water!

  23. 23. 9. What about the future? Reduction of CO2 emission is one of two main challenges when it comes to our climate. Adaptation of society to a changed climate is the other. In the coming years climate has to be integrated into many different contexts, e.g. the work culture in the City’s organisation, innovation and development, business promo- tion, education and educational institutions, purchasing and operations, planning, utility supply and large initiatives like European City of Culture 2017. The climate plans will be used for: • creating an overview as well as coordinating and prioritising the many different initia tives and projects • securing a lasting focus on the issue as well as involving citizens and the business world • continuous evaluation of whether the total effort is adequate for reaching the goal of CO2 neutrality by 2030 In many ways the climate plans will have major influence on a number of the decisions that the City of Aarhus as well as the citizens and the companies will be making during the coming years. 23
