The carbon factor of Europe's largest
electricity utilities continued to rise
in 2012
In 2012, the electricity generated by the 20 utilities in our selection fell 34 TWh, from 2,127 TWh to 2,093 TWh. This 1.6% decline on 2011 is a result of the strained economic environment in Europe, with an overall decline in the European economy of 0.4% by volume and 0.7% in the eurozone1.
The CO2 emissions of European electricity utilities, however, rose 0.6%, from 727 million tonnes of CO2 (Mt CO2) in 2011 to 732 Mt CO2 in 2012. This increase is primarily due to the transfer of their output to higher-carbon energy sources for two main reasons. Indeed, these forms of energy, less costly than alternative sources in the short term, increased in the southern European countries most affected by the economic crisis (primarily Greece, Portugal, Italy and Spain). In addition, 2012 witnessed a drop in the price of a tonne of CO2 in Europe, which only encouraged the use of fossil fuels. In the US, the shale gas revolution has driven up American exports of coal to Europe at prices that are very competitive with European gas which is becoming more and more expensive.
The accident in Fukushima, Japan, in March 2011 brought nuclear power under scrutiny in some European countries, in particular in Germany which has decided to progressively phase out nuclear energy.
This source of energy is being replaced by lignite coal which is becoming more widespread and accounts for
25.6% of electricity produced in Germany as compared to 22.7% in 2011.
Furthermore, the significant levels of precipitation in some countries (particularly in northern Europe) was sufficient to revive hydraulic power plants in 2012. This was not the case in Spain where, due to the drought, electricity companies produced very low levels of hydropower and resorted to coal.
Overall, the European carbon factor is on the rise,
reaching 350 kg CO2/MWh in 2012, up 7 kg CO2/MWh
on 2011 (+2%).
This illustrates an international trend in carbon emissions. It will now take a huge effort to meet the 2°C warming target, which would require an average decarbonisation rate of 6% per year between now and 2100 (see PwC study "Busting the carbon budget", 2013). The carbon factor continued to rise in 2012, therefore, after increasing slightly in 2011, preceded by three consecutive years of decline.
The 20 utilities in our selection generated over 60% (61%) of emissions in Europe's electricity and heating sector (27 countries).

http ://epp.eurostat.ec.europa.eu/tgm/table.do?tab=table&init=1&plugin=1&language=fr&pcode=tec00115 The biggest increases in emissions between 2011
and 2012 were recorded by:
• RWE: emissions up 17.3 Mt CO2 (12%) due to the increase in electricity output from coal and fuel sources.
• Vattenfall: after a decrease of 1.6 Mt CO2 in 2011, the company's emissions increased by 7.7 Mt CO2 (10%) in 2012 (despite an increase in electricity generated by nuclear power and hydropower), due to an increase in electricity generated by lignite-fired power plants in Germany.
• EnBW: after reducing its emissions by 3.1 Mt CO2 (16%) in 2011, the utility once again increased its emissions by 2.1 Mt CO2 (11%) in 2012, as a result of decreased nuclear input in favour of coal.
The biggest decreases in emissions between 2010 and 2011 were recorded by:
• CEZ: emissions down 11.6 Mt CO2 (30%) due to the action plans implemented by CEZ to reduce CO2 emissions through the renewal of coal-fired power plants and the use of power plants with the lowest possible carbon factor in addition to the use of the nuclear power plant in Temelin since December 2012.
• GDF SUEZ: emissions down 5.4 Mt CO2 (9%) due to the overall decrease in electricity production.
• EDF: emissions down 6.5 Mt CO2 (12%) due to a significant decrease in Edison's oil and gas activities in Italy.
• E.ON: after an increase of 4.6 Mt CO2 (5%) in 2011, the group decreased its emissions by 3.8 Mt CO2 (4%) in 2012. E.ON invested three times more in renewable energy than in conventional energy sources. On the other hand, overall electricity production decreased.

What role will electricity from
renewable sources play in
tomorrow’s Europe?
Between 2011 and 2012, the use of renewable sources in the energy mix of the 20 utilities in our selection grew from 16.7% to 19.1%. The annual net output derived from renewable energy sources was up 45 TWh. In the same period, electricity generated from non-renewable sources fell 79 TWh for a total drop in output of 34 TWh.

1. Context, purpose
and limits of the study
1.1. In 2012, output fell due to low
growth and an increased use of carbon
energy sources
With the ongoing economic crisis in Europe in 2012, European electricity utilities produced less electricity than in previous years.
The economic crisis has been most stifling for southern European economies. As a result, less electricity was generated overall, despite high industrial growth in other countries such as Germany.
In addition to the economic crisis, the debate on the energy transition has also had an impact. A trend has emerged to progressively phase out nuclear energy (France has set itself a target for 2025 to reduce nuclear output to 50% and Germany is aiming to progressively shut down nuclear production) in favour of renewable energy (100% of Denmark's energy mix by 2050), even if the use of renewable energy remains controversial: the cost of electricity from renewable energy sources is high and includes additional costs for the payment of subsidies granted to the renewable energy sector, and energy storage technology that would offset high energy demand during climatic fluctuations is far from market-ready. The European Union has set a target for 2020 to reduce its greenhouse gas emissions by 20%, increase the share of renewable energy in energy consumption to 20% and increase energy efficiency by 20%.
In 2012, our selection confirmed the trend to reduce nuclear power in Europe as several nuclear plants have been shut down, particularly in Germany.
The resulting production shortfall was not systematically compensated by renewables, as required by the energy transition, but rather by carbon fuels which have a much more competitive price against the backdrop of the economic crisis. Despite the increased use of fossil fuels, however, the share of renewable energy in the total energy mix increased this year.
Although less electricity was generated, CO2 emissions rose slightly in 2012 (0.4%) and even with a slight increase in the share of renewable energy, the CO2 emissions of the selection of utilities and hence the European carbon factor were not reduced (see Section 3.5).
1.2. Purpose of the study
The purpose of this study is to identify, consolidate, standardise and present comprehensive information on CO2 emissions by the largest European electricity utilities and to analyse the main trends between 2002 and 2012.
1.3. Limits of this study
We do not provide comments or opinions on energy prices or the impact of CO2 in the assessment of the companies included in this study.
6 | Climate Change and Electricity | 2013
2.1. Data collection in Europe
Most of the companies in our selection have posted data directly on their website or in their Annual Reports and/ or Environment/Sustainable Development reports. The transparency of the data disclosed did not significantly improve in 2012. While some companies explicitly published a geographic breakdown of CO2 emissions resulting from electricity generation as well as the related carbon factor, this information is more difficult to come by in the case of other companies which publish aggregate emissions data and do not distinguish between emissions attributable to heating (not included in the scope of this study) and those attributable to electricity production. Moreover, very few utilities provide explanations for changes in emissions figures. For companies producing both electricity and steam, aggregate CO2 emissions have been allocated to
electricity in proportion to the percentage of electricity in the total energy mix.
We are aware, particularly in cases where data has been extrapolated, that some data may be approximate. However, we believe that the margin of error regarding direct greenhouse gas emissions does not exceed 10%. Lastly, due to recent M&A activity in the energy sector, some companies included in the study have been replaced and data for previous years has been adjusted accordingly.
2.2. Coverage
The European Commission estimated Europe's total electricity output in 2012 at around 3,085 TWh2, down
0.9% on 2011. The companies in our selection therefore represent 2,093 TWh, or 68% of all electricity generated in Europe.
The emissions analysed in this report total 732 Mt CO2/ year, representing nearly 60% of emissions of the European electricity sector (EU-28).
2.3. Scope
To make the results of the study as relevant as possible, our scope included only:
-European emissions3;
-Emissions attributable to electricity generation (i.e., excluding emissions from subsidiaries in other sectors).
Where possible, emissions attributable to heat production were also eliminated.
When consolidated emissions data were unavailable, the figures from recent acquisitions were added using the control approach rather than the equity approach in accordance with the recommendations of the GHG Protocol4.
Changes in scope took place in 2012 at EDF to consolidate sites in Poland.
Wherever possible, historical data for companies included in this study were restated for the period 2002-2012 in order to highlight trends on a comparable scope basis. Details on consolidation are provided in Appendix B. Our selection now includes 20 companies.

2.4. Published information
2.4.1 European analysis (20 companies)
We analysed the 20 leading European electricity utilities based on the following criteria:
-production (in TWh). NB: we took into account electricity generated as opposed to electricity sold, which also factors in trading activities;
-emissions (in t CO2/year), corresponding to electricity generated;
-carbon factor (in kg CO2/MWh produced); -percentage of energy produced from renewable
sources;
-main trends in the carbon factor, CO2 emissions and the renewable energy ratio5.
2.4.2 Recalculation of historical data
We updated and recalculated historical production and emissions data for some companies in order to take into account recently published data.

3.1. Production – 2012 data
Electricity generated by our selection of companies fell 33.6 TWh (1.6%) between 2011 and 2012, chiefly attributable to E.ON, GDF SUEZ, EDF, Dong and EDP.
EDF remained the biggest producer of electricity in Europe. In 2012, RWE, in the UK, moved up from third to second place in the ranking. The company considerably increased its production generated from coal (up 8.2 TWh) as its market price became more attractive. RWE's production generated from natural gas also increased by 3.7 TWh thanks to the commissioning of a new power plant in Pembroke.

Pro forma emissions by companies included in our selection were up 2.6 Mt CO2 (0.4%) between 2011 and 2012. RWE remains the biggest emitter in Europe with 159 Mt CO2, representing about 22% of total emissions by the companies in our selection and 12% of the sector’s emissions in Europe (EU-28).
Enel joined the top five emitters as a result of an increase in its emissions of 2.7 Mt CO2. It replaced EDF which has reduced its emissions by 9% due to a significant decrease in its oil and gas activities in Italy. E.ON and GDF Suez saw a slight decrease in their emissions. Vattenfall's emissions increased by nearly 10%.

3.3. Carbon factor
The average carbon factor for Europe rose 7 kg CO2/MWh (2%) to 350 kg CO2/MWh in 2012 from 343 kg CO2/ MWh in 2011.
In all, 12 of the 20 companies included in our study reported an increase in their carbon factor – including EnBW, which saw a 47% increase.
Once again in 2012, EDF was chiefly responsible for maintaining a relatively low average carbon factor in Europe, due to bullish production levels and its widespread use of nuclear power. The carbon factor excluding EDF would have been 452 kg CO2/MWh.
Main increases in the carbon factor in 2012 versus 2011
• EnBW recorded a 118 kg CO2/MWh (47.1%) rise in its carbon factor compared to a decrease of 48 kg CO2/MWh in 2011, mainly due to a decrease in nuclear energy production following the shutdown of two nuclear power plants in spring 2011. At the same time, more electricity was generated from coal in 2012.
• Union Fenosa recorded a 119 kg CO2/MWh (43%) rise in its carbon factor, mainly attributable to a more significant share of electricity produced from coal-fired power plants in Spain.
• EDP recorded a 84 kg CO2/MWh (20.4%) rise in its carbon factor. Decreased production and a more widespread use of carbon fuel increased emissions.
• E.ON recorded a 69 kg CO2/MWh (17.1%) rise in its carbon factor as fossil fuels, such as coal and natural gas, still make up a large portion of the energy mix. Some nuclear power plants were forced to shut down in Germany. In addition, coal-fired power plants saw an increase in production as a result of the low cost of coal.
Main decreases in the carbon factor in 2012 versus 2011
• PVO recorded a drop of 67 kg CO2/MWh (62.9%) in its carbon factor due to a reduction in conventional non-renewable energy sources (gas, coal, fuel oil). The group's total output also fell, with a slight increase in the use of nuclear energy.
• Statkraft recorded a 64.3% decrease (14 kg CO2/MWh) in its carbon factor, which the company attributes to its greater use of hydropower in Nordic countries reflected by the increased share of hydropower in the energy mix from 90.8% to 97.2%.
• CEZ recorded a 30% drop in its carbon factor from 566 kg CO2/MWh to 395 kg CO2/MWh due to a greater share of nuclear and renewable energies in the energy mix.
• Verbund recorded a 33% drop in its carbon factor from 123 kg CO2/MWh to 82 kg CO2/MWh. This is the result of a greater share of renewable energy, mainly hydropower but also solar and wind power, in the total energy mix.

European carbon factor: 350 kg CO /MWh²
In kg/MWh
The carbon factor for some utilities was lower than the European carbon factor, due chiefly to an energy mix comprising mostly hydro and/or nuclear power. The companies concerned are virtually the same as in 2011 (Statkraft, EDF, Fortum, PVO, Verbund, Iberdrola & Scottish Power, GDF SUEZ and Dong) with the exception of Union Fenosa which increased its carbon factor and is now above the European average. The modest rise in GDF SUEZ Europe's carbon factor (1.2 % or 4 kg CO2/MWh) remains slightly below the European carbon factor. In 2012, EDF had the fourth lowest carbon factor in our selection of companies.

3.4. Major trends in CO
2emissions for 2011-2012
Companies track changes in their CO2 emissions from one year to the next. We sought to identify the main trends that emerged in 2012:
The biggest increases in emissions between 2011 and 2012 were recorded by:
• RWE: emissions up 17.3 Mt CO2 (12%) due to the increase in electricity output from coal and fuel sources. • Vattenfall: after a decrease of 1.6 Mt CO2 in 2011, the
company's emissions increased by 7.7 Mt CO2 (10%) in 2012. This is due to an increase in electricity generated by lignite-fired power plants (1.7 TWh) in Germany, despite an increase in electricity generated by nuclear power and hydropower.
• EnBW: after reducing its emissions by 3.1 Mt CO2 (16%) in 2011, the utility once again increased its emissions by 2.1 Mt CO2 (11%) in 2012 as a result of decreased nuclear output in favour of coal.
The biggest decreases in emissions between 2011 and 2012 were recorded by:
• CEZ: emissions down 11.6 Mt CO2 (30%) due to the action plans implemented by CEZ to reduce CO2 emissions through the renewal of coal-fired power plants and the use of power plants with the lowest possible carbon factor in addition to the use of the nuclear power plant in Temelin since December 2012. • GDF SUEZ: emissions down 5.4 Mt CO2 (9%) due to the

significant decrease in Edison's oil and gas activities in Italy.
• E.ON: after an increase of 4.6 Mt CO2 (5%) in 2011, the group decreased emissions by 3.8 Mt CO2 (4%) in 2012. E.ON invested three times more in renewable energy than in conventional energy sources. On the other hand, total electricity production decreased.

3.5. Use of renewable energy: significant
increase in 2012
3.5.1 Significant increase in electricity generated from renewable sources
Our analysis of the 20 biggest electricity companies shows that electricity generated from renewable sources increased considerably by 45 TWh (12.6%) from 2011 to 2012.
Taking into account the overall decrease in output over the same period (1.6%), the share of renewable energy in the total electricity output increased significantly over the past two years from 16.7% in 2011 to 19.1% in 2012 above the 2010 level when renewable energy accounted for 17.0% of the mix.
This increase was mainly attributable to favourable weather conditions and normal precipitation levels in 2012. The main source of renewable energy remains hydroelectricity, which represents 15,8% of the total electricity generated in 2012 (out of a sample of
14 electricity utilities accounting for 83% of 2012 output for the selection).
The European Union has set a target of 20% of renewable energy in the final energy consumption mix by 2020 (all types including electricity, heating, transport). The current level (19.1%) of electricity generated from renewable energy sources appears to be on target. However, a target set by Directive 2001/77/EC requiring 21% of electricity to be generated from renewable sources beginning in 2010 was not attained by the selection of utilities.

The utilities that produce the largest share of electricity from renewable energy sources are not high on this list which essentially features medium-sized utilities that are investing heavily in renewable energy to catch up.
In 2012, Scottish & Southern and RWE increased their use of renewable energy by 72% and 41%, respectively, mainly reflecting improved weather conditions as compared to 2011. Verbund increased output generated from renewable energy in 2012 by 26%. Verbund's renewable energy production is mainly from hydraulic energy sources and increased in 2012 as a result of favourable weather conditions which increased the yield of its hydraulic power plants by 22%. Lastly, Statkraft is still the utility that is most dedicated to renewable energy which accounts for 98% of its energy mix, mainly attributable to its hydraulic production capacities which rose 24% in 2012. Electricity from renewable sources generated by EDP fell by almost 25%, from 19.4 TWh in 2011 to 14.5 TWh in 2012.

This mainly reflects a steep decline of almost 50% in the hydrological index in Spain and Portugal, which in turn impacted the production of hydropower. Union Fenosa's and GDF SUEZ Europe's modest decreases in energy generated from renewable sources (16% and 8%, respectively) are attributable to an increase in the use of their coal-fired power plants, mainly a result of economic policies that encourage the use of coal. Drax also decreased production generated from renewables by nearly 50% between 2011 and 2012 and as a result returned to its 2009 level of 1.5 TWh, which only accounts for 5% of the energy mix, as a result of a significant decline in the use of biomass, which is its only source of renewable energy.

In the selection of companies, 19.1% of electricity was generated from renewable energy sources in Europe in 2012. This percentage rose from 2011 (16.7%), with an increase of 45 TWh in electricity generated from renewable sources in 2012.
Statkraft, Verbund and, to a lesser extent, Fortum have upheld their high dependence on renewable energy, primarily hydropower. In contrast, CEZ, Drax and RWE use very little renewable energy in production, with the share remaining roughly stable at around 5%. However, this does not reflect efforts made by CEZ and especially RWE whose use of renewable energy increased considerably but was drowned out by an increase in overall production.
3.5.3 Relationship between the use of renewable energy and the carbon factor

PwC | 17 We continued to observe a significant correlation
between the two criteria: utilities generating a large percentage of electricity from non-renewable sources tend to have a higher carbon factor.
This does not apply to PVO and EDF, which generate 56% and 79%, respectively, of all their electricity output from nuclear energy.
The inversely proportional link between the share of renewable energy in the energy mix and the carbon factor remains weak as in 2011. In 2012, several utilities increased their production of renewable energy thus reducing their carbon factor, in particular PVO and Statkraft, while other utilities saw their carbon factor rise (Union Fenosa and Drax). This confirms the link between a low share of renewable energy in the mix and a strong likelihood of a high carbon factor. Other electricity companies, however, saw their carbon factor rise while boosting their use of renewable energy (EnBW, Scottish & Southern and E.ON).
The following companies stand out in the graph above: • Union Fenosa's carbon factor increased significantly (43%) and its share of renewables decreased (14%) which is mainly attributable to the replacement of renewable energy with coal, the result of the Royal Decree 134/2010 which encourages the use of coal.
• PVO slashed its carbon factor but only slightly
increased its share of renewable energy, resulting from a decline in conventional non-renewable energy sources (gas, coal and fuel oil) and a slight increase in nuclear and hydraulic power.
• Statkraft's carbon factor also decreased significantly even though the share of renewable energy only grew by 3%. The issue here is the saturation point:
renewable energy accounts for 98% of the mix and further increases are unlikely, despite its efforts (it increased the use of renewable energy by 24% as compared to 2011).
• Scottish & Southern's share of renewable energy increased substantially (by 82%). However, the utility's carbon factor did not drop but rose by 5%, reflecting an increase in the use of coal-fired power plants as overall electricity output increased.
• EnBW's carbon factor increased significantly despite a rise in the share of renewable energy. This is due to the shutdown of nuclear power plants which resulted in an increase in the use of coal-fired power plants despite the utility's desire to increase the share of renewable energy in the mix mainly through the use of
hydropower given the weather conditions in 2013, and wind power.
In 2012, five companies did not increase the amount of electricity generated from renewable sources in their energy mix, compared to eight in 2011 and six in 2010. Some of these companies attribute this trend to the financial interest of coal, an energy source with a very attractive price. In theory, renewable energy sources clearly contribute to a reduction in the carbon factor. In 2012, the rise in the carbon factor (2%) is due to the increase in the carbon intensity of non-renewable energy (which increased 5.5%) offset in part by a decrease (3.5%) of the electricity generated from non-renewable sources in the energy mix.
The increase in the carbon intensity of non-renewable energy is related to the change in the price of fuel costs in Europe between 2011 and 2012 when the price of coal fell by more than 30% and the price of gas rose by more than 10%.

4. Change in the energy mix – focus on
renewable energy sources
We analysed the energy mix of 14 electricity companies in our selection, which represent 83% of the output used in our calculation of the carbon factor of Europe's electricity utilities.
Hydropower is still the main source of renewable energy used by the selection of 14 electricity utilities (15,8% of total output). Hydropower offset the sharp drop of 1.9points recorded in 2011 by the 14 electricity companies selected with an increase of 1.8 points in 2012. These differences are attributable to weather conditions.
Wind power is the second source of renewable energy for the selection of 14 electricity utilities and accounts for 1.4% of total output. Biomass and photovoltaic power account for 0.6% and 0.2%, respectively, of total output. This analysis carried out between 2011 and 2012 revealed a substantial decrease in nuclear energy (1.5 points) and a less severe decrease for fuel oil (0.9 points). The Fukushima disaster following the earthquake and tsunami in March 2011 and the scrutiny brought against nuclear power in several countries worldwide, including
Europe, has had real consequences, in particular for the energy mix in Germany. The reduction of power production from nuclear sources in Germany was not offset by EDF nuclear plants in France and in the UK. Despite the increased share of renewable energy in the energy mix from 16.7% in 2011 to 19.1% in 2012, coal still remains an attractive alternative to nuclear energy for the 20 companies in our selection.
Overall, electricity generated from non-renewable energy decreased by nearly 79 TWh between 2011 and 2012 for the 20 companies in the selection and electricity generated from renewable energy sources increased by 45 TWh during the same period.
As a result, the electricity market saw an increase in the share of renewable energy in 2012. However, this failed to reduce the European electricity sector's greenhouse gas emissions within a still stagnant economic environment.
