Spatial planning aims to improve the socioeconomic and environmental sustainability of a region, yet, in the spatial planning framework, it is difficult to capture the environmental impacts of the lifestyle of residents as a whole. We use carbon load as an indicator for environmental pressure and explore the spatial variations in carbon load from transport, domestic energy use, and the consumption of goods based on data obtained from the Household Budget Survey in Estonia, in an attempt to understand how residential location is related to the environmental load of household consumption. We use environmentally extended input-output computing for carbon accounting, multiple regression models for statistical analysis, and settlement hierarchy as an analytic tool for characterizing residential location. The results show that the capital region and other higher-level settlements provide favorable conditions for the consumption of leisure-related goods and services even when other socioeconomic variables are taken into account. Industrial cities dominated by apartment block housing are characterized by conservative consumption patterns of residents. For rural residents, a lower carbon load imposed from other consumption categories compensates for their higher dependency on cars. We conclude that there is a need for an integrated and balanced spatial planning policy that considers the entire consumption pattern of populations in different settlement types.

Nowadays, urban environments concentrate over half of the global population and will, it is estimated, surpass 70% by 2050. This concentration implies that many of the future challenges and opportunities emerging from their possible solutions will be in cities. One of the principal urban challenges is the carbon footprint of our cities and its reduction, by trying to exploit the potential of technological solutions. This ambitious transition, guided by the Smart Zero Carbon City (SZCC) concept, needs a flexible system of indicators, adaptable to different sizes of city, bearing in mind the main singularities of each one, so as to offer the most suitable interventions and to prioritize them. The principal objective of this study is centred on the characterization of cities in terms of the innovative SZCC concept, by applying the Smart Zero Carbon City Readiness Level (SZCC Readiness Level). A selection of indicators in the SZCC concept for analysing a set of key aspects of the main thematic areas of the city (Characteristics of the city; City plans and strategies; Energy; Mobility; ICT Infrastructures and services; Public Participation). This characterization informs the development of the SZCC concept in the city, detecting its strengths and weaknesses, in order to facilitate the selection of alternatives to move towards decarbonization. It is at the same time a manageable way of assisting decision-making in small and medium-size municipal councils that are so common in the European context and that usually have fewer resources than large capital cities. With a view to validating the selection of indicators, the SZCC Readiness Level was applied to 5 Basque cities that are representative of different urban typologies, analyzing their current situation in the light of the SZCC concept.

Urban sustainability is a major pillar in the European Union policy towards reaching Paris Agreement targets. In order to support cities and local communities around EU in their effort to implement innovative solutions and integrated approaches to increase their resource efficiency and climate resilience, European Commission funds the instrument "Smart Cities and Communities" (SCC) as part of its Research and Innovation Programme Horizon 2020 (H2020). The overall approach is to define and implement sets of innovative integrated sustainable actions in three main domains: energy, urban mobility and information and communication technologies at city/municipal level. The most innovative solutions are implemented by a number of lighthouse cities while follower cities closely observe the actions being performed in the lighthouse cities, and commit to select and put into practice the most promising and adaptable ones depending on their local conditions. Since 2015 four Bulgarian cities have been part of SCC projects, namely Sofia, Bourgas, Varna and Asenovgrad, participating as followers and working together with local communities from all across Europe leading the way towards urban sustainability and carbon emission reductions. Asenovgrad is supported by Sofia Energy Centre as partner in Horizon 2020 SmartEnCity Project where it cooperates with the lighthouse examples of Victoria-Gasteiz (Basque Country, Span), Tartu (Estonia) and Sonderborg (Denmark) on their path to achieve carbon neutrality in the long-term perspective. The article presents the overall H2020 SCC approach based on the implementation of most advanced processes, materials and products applicable to different areas of urban sustainability. Taking the experience of SmartEnCity lighthouse cities as a starting point, it is focused on the ways to successfully adapt the most promising solutions matching the specific Bulgarian conditions. In addition, on-going cooperation among Bulgarian follower cities has been initiated which helps in broadening the scope of possible measures and utilization of available knowledge beyond the project boundaries.
