This is the good practice's implementation level. It can be national, regional or local.
About this good practice
This action is carried out under the project Efidistrict, whose aim is to revitalize an ageing district to improve the quality of life of its residents (http://bit.ly/3ofKJud). The creation of a new District Heating with biomass, including a new heat plant and a distribution network was one of the three main actions of the project.
So, the renewal of these facilities to improve energy efficiency was one of the priority objectives, through the installation of a new District Heating (DH) on a neighborhood scale with centralized production and a distribution network to users, existing heat groups and public buildings in the neighborhood, optimizing production and incorporating renewable energies as fuel, specifically forest biomass which is a fuel with great potential for development in Navarra region.
Currently, the new heat plant is being developed to supply the heating and hot water networks of 4,000 homes and 8 public buildings in two phases.
From the LCA perspective, the carbon footprint for the use of fuel was calculated as part of the feasibility study for the planned heat central and network, under two assumptions: current situation with supply of natural gas and future situation with the new heat central and supply of 90% of biomass and 10% of natural gas. It was carried out according ISO 14067.
The main stakeholders and beneficiaries of the practice are: Government of Navarre, NASUVINSA, Pamplona City Council, Burlada City Council, Financial institutions, Neighbors

Resources needed
To calculate the Carbon Footprint, the participation of an expert on LCA and carbon footprint was needed during the execution of the feasibility study and the preliminary project. Both the feasibility study and the preliminary project were carried out by the Navarra Industry Association (AIN).
Evidence of success
The implementation of the new biomass heat plant will mean a reduction of more than 88% in CO2 emissions compared to current installations, according to the results obtained from the carbon footprint calculation in 2018 as part of the feasibility study, with a reduction of 6.782 tCO2 eq.
Other benefits associated: reduction of the energy dependency, enhancement of forest resources close to the point of consumption, local employment created (estimated in 135 jobs).

Potential for learning or transfer
Nasuvinsa investments for civil work, urbanization and networks have been financed 50% by ERDF Navarra 2014 – 2020 (http://bit.ly/2MbBxKi).
The actions included in Efidistrict have become part of regional policies, such as Navarra Housing Plan, Navarra Energy Plan Horizon 2020 and Navarra Energy Plan 2020-2030.
The project STARDUST (http://bit.ly/36illO6) has helped in the writing the feasibility study and tender specifications for the concession contract.
The strategy developed can be replicated and extended to other neighborhoods or regions to provide a framework for energy efficiency and show citizens that district heating systems are more efficient than individual heating systems, incorporating energy saving and the use of renewable energies as a priority.
The fact of including the calculation of the carbon footprint in the early stages of the biomass power plant project, allows to assess the reduction of CO2 emissions before its execution, as another tool for decision-making
