Part C - Italy Commonality (June, 1st 2010)Italy – Care

Italy is one of the European countries most vulnerable to the impacts of climate change, and its effects on its territory and resources are already visible. In particular, one main concern is the impact of climate change on the hydrological cycle, with consequences for the economic sectors for which water is a crucial, such as agriculture, tourism and energy. In the future, projected shortages, combined with an increase in demand, are likely to have severe impacts on water supply. Furthermore, other relevant issues like coastal erosion, hydro-geological risk, biodiversity loss and effects on human [IT1] health are expected to become more important as a consequence of future climatic variations.

 [IT1]Visto che stiamo citando delle conseguenze future del cambiamento climatico, ci sembrava opportuno precisare questo concetto anche rispetto alla “biodiversità” e alla “salute delle persone”.

The most recent figures for the national greenhouse gas (GHG) inventory show that emissions, in carbon dioxide-equivalent (CO2-eq) terms, increased from 517.05 million tonnes to 541.49 million tonnes during the period 1990-2008, a growth of 4.7 %, whereas, according to the Kyoto Protocol, Italy should have reduced its emissions, during the period 2008-2012, by 6.5 % compared to the 1990 level, down to 483.44 Mt CO2-eq.

Globally, Italy is responsible for no more than 1.51 % of overall emissions generated from fossil fuels, meaning that it ranks 12th among the countries with the highest levels of GHG emissions[1].


GHG emissions in Italy registered overall growth of 24.44 Mt CO2-eq between 1990 and 2008. During this period (Figure 1) there were reductions in fugitive emissions due to accidental losses during the production and distribution of hydrocarbons – by 3.39 Mt CO2-eq – as well as in emissions by manufacturing industries, 13.83 Mt CO2 eq; agriculture, 4.71 Mt CO2-eq; use of solvents, 0.46 Mt CO2-eq; industrial processes, 3.41 Mt CO2-eq; and waste, 1.32 Mt CO2-eq while emissions from the residential sector and services increased by 8.22 Mt CO2-eq along with those from energy industries, +19.74 Mt CO2-eq and the transport sector, +20.20 Mt CO2-eq. In 2006, for the first time since 1996, overall GHG emissions were lower than in the previous year, down by 1.85 %. This declining trend, mainly related to the effects of the global economic downturn, has been continued in 2007 and 2008.


The trend observed in GHG emissions is in line with changes in final energy consumption (Figure 2), an increasing trend is evident until 2005, with an increase of 20.7 % compared to 1990, followed by a decline of 2.9 % between 2005 and 2008. Preliminary indications for 2009 show a further decline of 1.2 %.


A decomposition analysis has been used to identify the main drivers behind the observed trends in GHG emissions. This technique has been applied to production-related GHG emission data from 1992 to 2006 (Femia and Marra Campanale, 2010). A comparison of trends in the main economic variables with GHG emission indices shows a strong growth of output and value added, while GHG emissions increased, though at a slower pace than the economy, thus showing relative decoupling[2]. In order to decompose changes in GHG emissions, the following four determinants were considered: level of economic activity (economic growth), weight of the different industries in the economy (structure of production), energy intensity of output (for example fuel-use efficiency) and emission intensity of energy use (effects of technological choices other than changes in fuel intensity).

The decomposition analysis of the increase in emissions between 1992 and 2006, amounting to about 24 million tonnes, shows (Figure 3) that the increase is exclusively due to economic growth. If the effects of economic growth had not been offset by the other components, the increase would have been about 30.8 %, instead of the actual 5.6 %.



In particular, the improvement of the two technological components emission intensity of energy use and energy intensity of output would have led to a 20.7 % reduction of emissions. The structure of production also played a significant, though less important, role in decreasing GHG emissions by 4.5 %.


A year-on-year analysis of the changes shows that the overall 1992-2006 change, a 9.5 % reduction, attributable to emission intensity of energy use was achieved mostly by cumulative small year-on-year efficiency increases over the period, suggesting a real, though slow, improvement of the environmental efficiency of Italian industry through the decrease of non-fuel dependent , for example from solvent use; the shift towards less polluting fuels; the use of technologies that improve production processes, such as integrated technologies; and the installation of end-of- pipe devices for emission abatement.


In contrast, the energy intensity of output effect is characterised by an irregular pattern, with sudden and often large changes from year to year, such as a 3.4 % increase in 2003 and a further increase in 2005 and 2006, suggesting that energy use was becoming less efficient. In fact, this component takes into account the effects of some possible real improvements – the introduction of less fuel-intensive techniques and the replacement or removal of energy-wasting machinery or plants – but its overall importance and volatility may be explained, at least partly, by the delocalisation of Italian industrial production, with more and more intermediate and final products of being manufactured abroad with only the final stages of production being performed in Italy.




The transport system has had to respond to a sharp rise in the demand for mobility. During the period 1990-2008, the demand for passenger transport increased by 34 %, while the demand for domestic freight transport for distances of more than 50 km grew by 23.2 %.

Growth in passenger demand remained steady during the period 2000-2005, followed by increases over the following two years. In 2008, there was a drop of 4.7 % in the demand for transport.

The demand for passenger transport continues to be met mainly by road transport, the least efficient mode from energy and environmental perspective. In 2008, cars, motorcycles and scooters were used for 81.6 % of passenger travel.

Italy ranks second, after Luxembourg, in terms of the ratio of cars to resident population, but ranks first when motorcycles, scooters and commercial vehicles are included. Worldwide, only the USA has a higher number of vehicles per inhabitant.


The demand for passenger transport has been growing since 1990, being closely tied to the dynamics of economic development.

Domestic transport of freight by Italian carriers is primarily by truck, 68.2 % in 2008, the share having remained fairly constant since 1990. A significant increase for truck sharing was observed for 2000-2005, followed by decreases in subsequent years. 

In 2008, sea accounted for 17.7 % of domestic freight transport and rail for 9.5 %, while air transport represented a marginal 0.4 % of freight transport; the increase in other modes after 2000 in Figure 5 is due mainly to increased transport of freight by sea.

The 2020 outlook

Part C - Italy- Commonality (June, 1st 2010)- 2020 outlook

As concerns the implications for Italy of the EU GHG emission reduction target of at least 20 % below 1990 levels by 2020 established by the Integrated Energy and Climate package, the effort-sharing directive translates the target for non-Emissions Trading Scheme (ETS) sectors into an emission reduction target of 13 % by 2020 compared to 2005 levels, whereas the revised EU-ETS Directive establishes an overall cap to emissions from EU ETS sectors in the entire European Union, corresponding to a 21 % reduction by 2020 compared to 2005. The preliminary analysis shows that in 2020:

  • according to the trend scenario, overall GHG emissions will amount to 611.4 Mt CO2-eq. corresponding to an 18.3 % increase compared to 1990 and a 6.4 % increase compared to 2005;
  • emissions from the ETS sectors will amount to 255.0 Mt CO2-eq. plus 4.0 Mt CO2-eq. from aviation activities;
  • emissions from non-ETS sectors will amount to be 352.4 Mt CO2-eq. according to the trend scenario, and 313.7 Mt CO2-eq.  including reductions achievable through policies and measures already implemented, 38.7 Mt CO2-eq.


Taking into account additional measures already identified, which include the use of credits from project-based mechanisms but exclude emission reduction units from carbon sink activities, the remaining gap to the 2020 objective amounts to 10-18 Mt CO2-eq./year.


However, the energy projections underlying the emission scenario provided in the report date back to late 2008: they include the first effects of the economic crisis, but not the continuing general downturn of the world economy. Consideration of changes in international trade, to which the Italian industrial system is very sensitive, might result in a reduction of energy-related CO2 emissions in 2010, 2015 and 2020, thus facilitating the achievement of both the Kyoto and the 2020 targets.

Within Italian energy policy, the most effective tool to reduce GHG emissions from electricity supply has been support for cogeneration, Combined Heat and Power (CHP), which makes it possible to increase the conversion efficiency of energy from primary sources. Since 1997, net electricity generation through thermal cogeneration has followed a trend parallel to total electricity generation from thermal power plants, (Figure 6): between 1997 and 2008 the average annual increase was approximately 5 424 GWh/year for electricity produced through combined heat and power generation, while the overall average increase in total electricity generation from thermal power plants was 5 487 GWh/year. The figures for the production of electricity without heat recovery remained almost constant during the period considered. These figures show that, since 1997, the need for new electricity from thermal power plants has been completely met through cogeneration. This trend was also influenced by the increasing use of natural gas for electricity generation in thermal power plants. This is due not only to the low CO2 emissions factor of natural gas, compared to other primary sources, but also to the greater efficiency of combined cycles fuelled by natural gas. For instance, during the period 1996-2008, the average specific consumption of natural gas for net electricity generation decreased by 20.1 %.


EU Directive 2006/32/EC sets objectives for Member States regarding the efficiency of energy end-uses and energy services: the general national target for energy savings is 9 % within the ninth year of the application of the directive – 2016. Under the provisions of Article 4, Member States must enact effective measures to meet this target. The Action Plan for Energy Efficiency, presented by Italy in July 2007 identifies a series of measures that will make possible energy savings of 9.6 % in 2016, compared to average energy consumption of 2001-2005. In this framework a key role is played by the system of white certificates, stipulated under Article 6 of Directive 2006/32/EC.


The Italian White Certificates or Energy Efficiency Titles (EET) scheme was originally introduced in July 2001 by means of two Ministerial Decrees[1] as an innovative approach to combine a command and control policy with a market-oriented instrument, and started in 2005. According to those decrees, Italian Distribution System Operators (DSO) of gas and electricity with more than 100 000 customers were obliged to achieve energy savings not lower than the target defined within the scheme.

The initial targets were modified by two new Decrees approved in April 2006[2] and, later, by the Decree of the Ministry for the Economic Development of 21 December 2007[3].

This last decree extends the scope of the law to DSOs with 50 000 customers and allows companies with an Energy Manager on their staff to operate in the energy efficiency programme, and also Energy Saving Companies (ESCOs) and/or companies controlled by DSOs to operate in the scheme.

In addition, it introduces new targets for 2008 and 2009 and extends the commitment period from 2009 to 2012, according to Table 1:


Table 1: National target for primary energy savings

Since the start of the scheme, the following savings have been achieved:

ü     2005-2006 (target 2005): 286 837 toe;

ü     2006-2007 (target 2006): 611 529 toe;

ü     2007-2008 (target 2007): 903 627 toe;

ü     2008-2009 (target 2008): about 1 818 000 toe

for a total amount of 3 620 000 toe; this means that the 2005, 2006 and 2007 targets have been exceeded – the figures for 2008 are still preliminary. As concerns the type of fuel which has been saved, savings can be split as follows:

ü     77% as electricity;

ü     19% as natural gas;

ü     4% as liquid and solid fuels.


Since the early 1990s, several different schemes have been introduced to promote renewable energy sources. A feed-in tariff system was adopted in 1992 – CIP 6 – but its high costs and unsatisfactory results suggested its suspension, provided for by the decree 24 January 1997.  Under this decree, only plants already operating or at least under construction at the time of its entry into force could still qualify for the CIP 6 incentives. A new incentive scheme, based on a market-oriented mechanism, was later introduced through legislative decree 79/99. This introduced an obligation on electricity generators and importers to feed the grid with a minimum share of electricity produced from renewable sources. The obligation started in 2002. The initial share was set at 2 % of total electricity produced or imported, exceeding 100 GWh, but an increase of this quota over time was already planned in the decree. Providers are allowed to fulfil their obligation by different means:

-     they can generate the required share of renewable electricity by setting up new renewable capacity;

-     they can import the required share of renewable electricity from countries where a similar mechanism is in force;

-     they can purchase the relative quota, represented by Green Certificates, on the market.


Photovoltaic electricity generation benefits from a dedicated scheme. The decree of 28 July 2005, later amended by the decree of 6 February 2006, introduced a feed-in tariff system for electricity produced by photovoltaic conversion of solar energy.


The installed capacity of renewable energy sources increased by approximately 1 000 MW in 2007 and 1 500 MW in 2008, with an increase of 4.7 % between 2006 and 2007 and 7.0 % between 2007 and 2008. In 2008 the electricity produced from renewable sources was approximately 59.7 TWh, while total electricity production was 318.2 TWh, meaning that electricity from renewable sources accounts for 18.8 % of total electricity production. The overall production trend is influenced by fluctuations in the share of hydroelectric energy as a result of meteorological conditions, as well as the growing contribution of  wind power, geothermal energy, biomasses and waste. For 1997-2008 there have been noticeable increases in the production of electricity from wind power, from 117.8 to 4 861.3 GWh during for 1997-2008, and energy from biomasses/waste, from 820.3 to 7 522.5 GWh, as well as from geothermal energy, from 3 905.2 to 5 520.3 GWh. The contribution of photovoltaic energy has increased significantly in the last two years from 39.0 GWh in 2007 to 193.0 GWh in 2008, but its share remains negligible. Despite recent increases, gross electricity generation from renewable sources remains well below the objective of approximately 75 TWh by 2010, established by Directive 2001/77/EC, if imports of electricity produced from renewable sources are not taken into account. The same considerations apply to the share of renewables in primary energy consumption; according to Directive 2009/28/CE, the consumption of energy produced from renewable energy sources should, in 2020, reach 17 % of the gross inland consumption in Italy – the most recent value is 6.9 % in 2007.


Fuel consumption in the transport sector has increased steadily since 1990, by around 22.4 % between 1990 and 2008. The percentage of fuels with low environmental impact, natural gas, LPG, bio-diesel, out of total fuels shows irregular results, going from 5.6 % in 1990 to 6.9 % in 2008. The recent increase in the consumption of natural gas and bio-diesel has been partially offset by a drop in LPG sales starting from 1997.


Based on the available data, it is clear that the limited progress made in the transport sector through the implementation of technological measures involving engine efficiency are being offset, to a greater extent in Italy than in the other European countries,  by growth in the demand for transport, especially by road, meaning that the environmental impact of the transport sector continues to grow.


As concerns other GHG emissions, implementation of national and EU waste legislation has influenced trends in methane (CH4) and CO2 emissions from this sector, and is expected to continue to have significant impact. The disposal of municipal solid waste (MSW) in landfill sites is still the main disposal practice, but the percentage of municipal solid waste disposed of in landfill sites dropped from 91 % in 1990 to 49 % in 2008 as both waste incineration and, particularly, composting and mechanical and biological treatment have increased.

In particular, net CH4 emissions from landfill sites have decreased dramatically from 219.1 Mt in 1990 to 74.1 Mt in 2008 due to the collection of landfill gas in all managed disposal sites and its subsequent combustion for flaring or energy purposes.


In contrast to the increase in GHG emissions resulting from various production activities and deforestation, a significant amount of CO2 has been removed from the atmosphere by the Land Use, Land-Use Change and Forestry (LULUCF) sector. In Italy, this sector, which includes emissions and removals from different land uses such as forest land, cropland, grassland, settlements and wetlands, and land-use changes, accounted for 64.76 Mt CO2-eq. in 1990 and 87.30 Mt CO2-eq. in 2008. However, only the fraction removed from managed forests is accountable under the Kyoto Protocol, according to Article 3.3, afforestation, reforestation and deforestation, and Article 3.4, forest management[4].
