Recent climate change, environmental design, and ecological conservation policies require new and existing urban developments to mitigate and offset carbon dioxide emissions and for cities to become carbon neutral. Some North American models and tools are available and can be used to quantify the carbon offset function of urban trees. But, little information on urban tree carbon storage and sequestration exists from the European Southern Alps. Also, the use of these North American models in Europe has never been assessed. This study developed a protocol to quantify aboveground carbon (C) storage and sequestration using a subsample of urban trees in Bolzano, Italy, and assessed two existing and available C estimation models. Carbon storage and sequestration were estimated using city-specific dendrometrics and allometric biomass equations primarily from Europe and two other United States models; the UFORE (Urban Forest Effects Model) and the CUFR Tree Carbon Calculator (CTCC). The UFORE model carbon storage estimates were the lowest while the CUFR Tree Carbon Calculator (CTCC) C sequestration estimates were the highest. Results from this study can be used to plan, design, and manage urban forests in northern Italy to maximize C offset potential, provide ecosystem services, and for developing carbon neutral policies. Findings can also be used to predict greenhouse gas emissions from tree maintenance operations as well as estimating green waste yield from landscape maintenance activities and its use as biofuel and compost. Managers need to be aware that available models and methods can produce statistically different C storage and sequestration estimates.Keywords: i-Tree Eco; growth rates; allometric equations; ecosystem services; CTCC model Introduction Climate change is one of the most important and pressing environmental, economic, and security issues our world faces today (Barnett 2003;IPCC 2007;Karagiannis & Soldatos 2010). Urban areas are steadily growing throughout the world (Grimm et al. 2008) and by 2030 it is expected that 60% of the world's population will be living in cities (Rydin et al. 2012). Thus, as urban environments become more important as living space for humans, they are an increasing source of carbon emissions.Several studies in North America, China, and Australia (Brack 2002;Zhao et al. 2010;Dobbs et al. 2011;Martin et al. 2012;Roy et al. 2012), and more recently in the United Kingdom and Germany (Davies et al. 2011;Strohbach & Haase 2012;Strohbach et al. 2012), have shown that trees in urban environments remove carbon dioxide from the atmosphere through growth and photosynthesis, and store excess carbon as biomass in roots, stems, and branches. Indirectly, urban trees also reduce building energy used for cooling through their shade and climate amelioration effects, thereby reducing CO 2 emissions from decreased energy production (Akbari et al. 2001).The estimation of tree carbon sequestration depends on species types and their mortality and growth characteristics as well as their overall con...

“…There are numerous references that confirm that the main disadvantage of using renewable energies stems from adverse climatological factors-rain, sun, wind [7,8]. By contrast, the main advantage of geothermal energy, both in its isolated form and in the form of an energy mix lies in its complete year-round availability and the fact that it does not need to oversize the capacity of the system to compensate for lack of energy.…”

“…Furthermore, solar and wind energy have a negative impact on the landscape and farming land. This is not the case of geothermal systems due to its concealed nature [7,8]. Many articles mention the need to implement renewable energies and improve energy efficiency in remote areas, such as islands not only from an environmental point of view (CO 2 and greenhouse gases emissions reduction) but also because they have proven to be more profitable than conventional polluting energy sources, where part of the cost of the bill is often subsidized [1,2,7,8].…”

Measures to Remove Geothermal Energy Barriers in the European Union

This article examines the main market barriers that hamper the introduction of geothermal energy at local, national, and European levels as well as the necessary steps that need to be taken to eradicate them, thus contributing to the general use of this renewable source of energy. The novelty of this study lies in the detailed description of four different scenarios: the European Union (EU), Spain, the Canary Islands, and the agricultural sector for the three types of geothermal energies and their uses: Low-enthalpy or thermal uses, high-enthalpy or electrical uses and renewable energy mix. The results are expected to differ in terms of level of introduction, barriers, and measures to be taken. We have selected Spain within the European context due to its meagre 0.1% geothermal market share in primary demand for renewable energy, and the Canary Islands in particular, given its insular nature. We have likewise picked the agricultural sector due to its underdevelopment as far as renewable energies are concerned, including geothermal energy.

“…For islands where water scarcity is a reality, desalination can be considered as an alternative solution (Calero and Carta, 2004;Karagiannis and Soldatos, 2010;Psychogiopoulos et al, 2008;Kaldellis and Kondili, 2007). Subsequently, there are also places where desalination could effectively be applied in combination with renewable energy sources and pumped hydro storage systems (Segurado et al, 2011;Akash et al, 1997).…”

Feed-in tariffs for promotion of energy storage technologies

et al. 2011

a b s t r a c tFaster market integration of new energy technologies can be achieved by use of proper support mechanisms that will create favourable market conditions for such technologies. The best examples of support mechanisms presented in the last two decades have been the various schemes for the promotion of renewable energy sources (RES). In the EU, the most successful supporting schemes are feed-in tariffs which have significantly increased utilisation of renewable energy sources in Germany, Spain, Portugal, Denmark and many other EU countries. Despite the successful feed-in tariffs for RES promotion, in many cases RES penetration is limited by power system requirements linked to the intermittency of RES sources and technical capabilities of grids. These problems can be solved by implementation of energy storage technologies like reversible or pumped hydro, hydrogen, batteries or any other technology that can be used for balancing or dump load. In this paper, feed-in tariffs for various energy storage technologies are discussed along with a proposal for their application in more appropriate regions. After successful application on islands and outermost regions, energy storage tariffs should be also applied in mainland power systems. Increased use of energy storage could optimise existing assets on the market.
