Bottom Up to Kyoto (BUTK)

Download PDFDownload PDF
To reduce CO2 emissions, more use of energy-efficient lighting products must be made. Several obstacles prevent this from happening, such as the higher purchase price or a lack of understanding of the long-term benefits. Using three municipalities as examples, ButK aimed to help overcome barriers to switching to energy-efficient lighting technologies and to provide tender specifications and procurement standards to other municipalities, thereby helping Europe meet its Kyoto targets. Each municipality was provided with a tailor-made energy-efficient lighting strategy which can serve as a model.


  • Analysis of and report on the key legal aspects for implementation of Third Party Financing project for public street lighting and indoor lighting in the partner municipalities. Collection and reporting of street and/or office lighting date of each municipality and calculation of CO2 emission and potential savings attributable to lighting.
  • Three technical and economical feasibility studies identifying the various optional technical solutions, related costs and benefits in terms of CO2 reduction, and clearly indicating the “pay back period”. Public tenders for the modernisation of street and road lighting systems prepared and released by in 3 countries. Contracts with successful bidders prepared and signed in 3 countries.
  • New efficient street lighting systems installed in 2 countries and installation contracted in the third country.
  • Reduction of CO2 emissions in the 3 partner municipality spread from 43% to 52 % upon monitoring of the realised investment. 9 workshops having attracted 200 participants, including decision makers.
  • Newsletters, press articles, presentations at conferences, stand at fairs to inform a large specialised and nonspecialised audience A multilingual website containing relevant documents for potential replication on larger scale.

Lessons learned

  • Municipal partners acquired experience with Energy Performance Contracting (EPC) and Public Private Partnership (PPP) for public lighting. Data collection allowed detailed inventory of public lighting equipment in the partner municipalities. The tendering process gave the (few) ESCOs in the partner countries the opportunity to present themselves and call the attention of several municipalities to their activities.
  • Increase transparency on street lighting expenditures. Highlight different options available to resolve problems associated with the renovation of street lighting systems; e.g. solution for financial restrictions (contracting / leasing). Allow testing new technologies e.g. LEDs.
  • Data collection can be a difficult exercise. Implementation may be delayed by disputes caused by unsuccessful bidders or by national legislation (e.g. light pollution standards and other national activities) requiring modifying the planned investment. Resistance of working with the private sector: in some countries this appears to be motivated by “solidarity” with existing maintenance teams and the (reasonable) fear of losing know-how within the municipality workforce.
