Copenhagen Climate PlanCarbon Neutral by 2025
Hanne Christensen
Environmental Department, Technical and Environmental Administration
City of Copenhagen
Copenhagen Climate Plan• Approved by the City Council in August 2009• 50 initiatives in 6 focus areas
2025 Carbon Neutral Copenhagen2015 20 % CO2-reduktion
•Reduction of 20% CO2 from 1990-2005•BNP has increased by app. 66% in the same period
CO2-emissions 2005
• 20% reduktion equals a reduction from app. 2.500.000 tons to 2.000.000 tons CO2
50 initiatives in 6 focus areas
Energy production in Copenhagen
• District heating system since 1915• 98% of households connected• Combined Heat and Power Plants (CHP)• Waste management systems (Amagerforbrænding)• Wind turbines on the Middelgrund
Energy supply initiatives towards 2015 Biomass:• Converting existing coal CHP to biomass• Preparing a new biomass based CHPOther renewable energy sources:• Wind turbines – in Copenhagen and outside• Geothermal heat – expansion of existing plantEnergy efficiency:• Efficiency at incineration plants• Lower temperature in the district heating system• District cooling systems based on surplus heat• Converting steam to water in the district heating system
Towards carbon neutral Energy supply 2025Energy supply• More renewable energyIntegrated energy system• Fluctuating energy sources• Heat and electricity storageWaste• Eliminate the fossil content in
waste Energy demand• Energy savings• Energy efficiency • Retrofitting of buildingsUrban development• Low Energy buildings
Renewable energy sources
Biomass • Profitable due to national subsidies and taxes• Higher prices – demands in Europe• Sustainable criteria
Wind turbines• Wind turbines onshore and offshore
Geothermal heat:• 2-3 new plants in Copenhagen
Local energy production:• Solar power and heat• New technology
Waste incineration• Production of more electricity and heat when needed
• Content of plastic causes carbon emissions
• Recycling of plastic possible – some fractions
• Actions needed
• Separation - households etc.• Sorting at the plant• Other materials
Integrated and intelligent energy systems 2025
Possible solutions:• Electricity storage as hydrogen or
batteries• Collection of heat du to conversion loss• Transformation of power in to heat through
heat pumps• Storage of fuel eg. waste and biomass• Seasonal storage of heat • Intelligent management of electricity
demand• etc.
