Sonderborg reduced CO2 by nearly 40 per cent despite increased consumption

Sonderborg municipality’s total CO2 emissions have been reduced by a further 2.7 percentage points in 2018, and overall CO2 emissions have fallen by 38.3 per cent since 2007. Meanwhile, energy consumption in 2018 increased by 1.7 percentage points.

Since 2007, total CO2 emissions in Sonderborg Municipality have been reduced by 38.3 per cent. In 2018 alone, CO2 emissions have been reduced by 2.7 percentage points. The reduction in 2018 is primarily due to a phase-out of oil for heating in private households and a decline in CO2 from imported electricity. This is the conclusion in a monitoring report published by the public-private partnership ProjectZero created to guide Sonderborg toward CO2 neutrality not later than 2029.

The reduction in Sonderborg comes as no surprise as the municipality has set ambitious goals. In December 2018, the City Council of Sonderborg approved their plan for reducing emissions by 75 per cent by 2025 under the name Roadmap2025. The plan focuses on further reducing the emissions through energy savings as well as the further conversion of energy system toward solar, wind and bioenergy.

“I am pleased that the Sonderborg area's CO2 emissions continue to decline and that we largely follow the ProjectZero vision's CO2 reduction goals. Furthermore, the report by ProjectZero confirms that we must have full focus on the implementation of the 50 projects that are described in Roadmap2025, so we can reduce our energy consumption,” says Sonderborg Mayor Erik Lauritzen, who is also the Vice Chairman of the ProjectZero Fund.

Focus on biogas

Sonderborg Municipality is moving ahead on new projects that will transition energy toward renewable energy. A new biogas plant in Glansager is under construction and is expected to be commissioned in 2020. The plan for building a new district heating plant in Nordborg is on schedule and expected to reduce natural gas consumption even more. Both projects that in the years ahead will help to ensure the Sonderborg area significantly more renewable energy.

The monitoring report also shows that energy consumption in 2018 has increased by 1.7 percentage points and thus the trend of declining energy consumption has been broken, for the first time since 2013.

“The trend in energy consumption in 2018 shows that we must strengthen energy efficiency efforts. Reducing energy consumption is an important part of the ProjectZero vision's DNA. It is best realised through energy renovations in private homes and housing associations, as well as through companies' efforts to improve their processes and operations,” says ProjectZero CEO Peter Rathje.

The ProjectZero CO2 monitoring report aims to calculate the past year's energy consumption, convert this into CO2 and analyse deviations.

It has been necessary to adjust the calculation method for oil for transport as the Ministry of Taxation, based on the EU's GDPR, has chosen to remove postal codes in data extraction used from the central vehicle register. Therefore, it is no longer possible to identify cars registered in Sonderborg Municipality. To calculate the oil consumption for transport, a method has been chosen which leads to comparable results and still leans up the central vehicle register.

The ProjectZero CO2 monitoring report is validated by the consulting company PlanEnergi.

The following projects contributed to CO2 reductions

  • Since 2016 750 oil furnaces were scraped
  • Sonderborgs district heating companies continue there green transition and use less fossil fuels
  • In 2018, Sonderborg District Heating got 100 new custoners
  • Coal consumtion at the local brick factories rose with 8 %
  • The 25 MW PV field in Glansager was connected to the grid in december 2018 which more than doubles the Sonderborg areas PV capacity

The following projects are currently on their way to be realized

  • Biogasplant in Glansager is under construction and will be put into operation in 2020

  • The plan for building a new district heating plant in Nordborg is on schedule and expected to reduce natural gas consumption even more.

  • The environmental consequence assessment for the Lillebælt Syd windturbine park was sent to the danish energy agency and is assumed to be processed during 2019

  • Roadmap2025 was approved by the city council in december 2019 and show the path towards 75 % CO2 reduction in 2025

Monitoring methodology

The methodology for calculating the Sonderborg areas CO2 emission is outlined in ProjectZeros Masterplan2029 (developed in 2009).
