Page 2 Carbon Footprint

In the last years it has become clear that energy resources are not inexhaustible and that the us-age affects our environment. We see it as our duty to deal with our environment in a sustainable way. In addition to creating good and sustainable products, we also take into account our envi-ronment and our employees, while a motivated organization is the key to sustainable success.

We are convinced that we find the right balance between People, Planet and Profit with a good CSR policy. Therefore we are working for many years according to this policy. For example, we have established our Carbon Footprint and we are busy to realize our reduction targets in the area of energy consumption and CO2 emissions. We are also very active in recycling and redu-cing the material consumption in our products. Also by an active Health, Safety, Environmental and Energy policy we are improving our work environment.

Sustainability is a joint effort of our employees, customers, business partners, suppliers and other stakeholders. Together with these partners, we are convinced that we can shape our policy in the future and continuing to play a leading role within our industry.

Organization

Page 3 Carbon Footprint

Responsible person The person statutorily responsible for the reporting organization is mr. P.L.B. Ummels, MD Pipelife Nederland B.V.

Organizational boundaries The organizational boundaries of Pipelife Nederland B.V. are determined in the context of CO2 (carbon dioxide)-consciousness in accordance with the principle of the operational sphere of influ-ence of the certifying company.

Within the GHG protocol, this is described as the 'operational boundary'. In practice, this means that when activities are executed under the auspices of Pipelife Nederland B.V., the accountability for the CO2-production is taken: the own organization has control of this.

Based on the lateral purchase analysis of the CO2 -performance ladder, it is determined that Pipelife Deutschland GmbH & CO. KG is added within the organizational boundary of Pipelife Nederland B.V.

The organizational boundaries for this inventory includes:

Pipelife Nederland B.V.;

Twebotube B.V.;

Pipelife Deutschland GmbH & CO. KG,.

The rationale for this boundary is listed in the boundary report (doc. nr 11.A0138b).

Carbon Footprint Analysis

Basis of analysis

CO2-emissions and absorptions by activities of the organization have been identified based on the established operational limits. At the identification of emissions a distinction has been made be-tween three sources of emission (known as scopes) into two categories: direct emissions and in-direct emissions. This is in line with the Greenhouse Gas (GHG) Protocol.

Scope 1 covers direct emissions under control, and controlled by, the organization. Exam-

ples include the combustion of fuels in machinery, business transport with vehicles owned by the reporting organization and emissions of refrigeration and air conditioning systems;

Scope 2 includes indirect emissions from purchased electricity, steam or heat;

Scope 3 includes other indirect emissions from sources such as commuter travel, produc-

tion of purchased materials and outsourced activities such as freight.

This carbon footprint analysis includes the CO2-emissions (one of the six greenhouse gases) of Pipelife Nederland BV, in scope 1 and 2 of the first half of 2011. The CO2 emission is analyzed in accordance with the “CO2 prestatieladder”, manual 2.0 june 2011.

Measurement results and explanation

Reported period Pipelife Nederland B.V. has synchronized its carbon footprint reporting period with its fiscal year. The fiscal year for Pipelife Nederland B.V. runs from January 1 to December 31. The reported period is the first half of 2011.

YEAR 2, NR. 1 Page 5

Scope 1: Direct CO2-emissions

THE DIRECT CO2 EMISSION IS MEASURED AND CALCULATED AS 1.163,8 TONNES CO2

Fuel use own car fleet (business car travel) In the first half of 2011 33%, 385,9 tonnes of the CO2 emissions is assigned to the fuel consump-tion of the fleet with 55 leased cars. In 2011 H1 the leasing company has reported an usage of 117.377 litres diesel and 4.393 litres of petrol and 867 litres LPG and 18.733 fleet kilometres.

Stationairy combustion equipment 574,7 tonnes CO2 (314.927 m3 ,49% of the total direct emission) is the result of consumption of natural gas. The natural gas is used for heating of the locations. 314.927 m3 is used in stationary combustion equipment, 81% of the consumption is in Enkhuizen.

Gasses In the first half of 2011 54,2 tonnes of CO2 emission is caused by the usage of the gasses CO2 gasses, Acetylene, Propane, Butane and Sagox 18 for the production processes in the Nether-lands and Germany.

CO2-emissions from burning biomass The combustion of biomass did not occur at Pipelife Nederland B.V.

Statement of CO2 sources and sinks omitted All identified sources and sinks of CO2 are included in the report. Storage of CO2 does not occur; there are no sinks.

Leakage of cooling gasses In the first half of 2011 149,0 tonnes of CO2 emission is caused by the consumption of cooling gasses in the production processes in Germany and cooling and freezing systems. These sys-tems for storage and transportable air conditioning-units are regarded as a closed system. There-fore only CO2-causing emissions of consumption are calculated.

Scope 2: Indirect CO2-emissions

INDIRECT CO2-EMISSIONS MEASURED AND CALCULATED ARE 6.904,0 TONNES CO2

Electricity purchased 98,1 % of the indirect CO2 emis-sion is caused by consumption of the repurchased electricity.

In the reported period, the electric-ity consumption was 14.887.524 kWh, this is 6.773,8 ton CO2 emis-sion. Under the terms of the CO2–prestatieladder, the electricity is registered and calculated with a grey label performance.

Based on the energy management system of Pipelife Nederland the extrusion processes caused 54,5% of the consumption of electricity, second Injection Molding caused 23,8% of the usage. Lighting caused 4,2% of the consumption.

Business air travel In the first half of 2011 employees in the Netherlands and Germany made flights for business purposes. 16% of the flights concerned flight distances between 0 – 700 km, 34% of the flights concerned flight distances between 700 – 2500 km and 50% of the flights concerned flight dis-tances more than 2500 km. The air travel caused 124,5 ton CO2, 1,8% of the indirectly CO2 emis-sions.

Heat Delivery Twebotube in Enschede reported in the first half of 2011 an usage of 118 GJ for heating (1,3 ton CO2).

Personal cars for business travel In the first half of 2011 several employees used their private car for business purposes and de-clared the mileage. The total mileage declarations by private car were 20.955 km in the reported period. This leaded to 4,4 ton CO2, 0,1% of the indirectly CO2 emissions.

SCOPE 1:

The fuel data of stationary combustion equipment for heating is provided by the energy suppliers of the locations and controlled with the internal measurements. For the location Flevolaan Pipe-life has a joint heating installation with the neighbour company Renolit. Renolit has specified the information for natural gas on the location Flevolaan. The data of gasses are provided by the suppliers. These information is deemed as sufficiently reliable.

The fleet management data is provided by the fuel suppliers of the leasing companies who man-age the fuel passes linked to the vehicles and by declarations of the fuel in fleet cars by employ-ees. Because the mileage registration is less accurate, since not every employee carefully keeps track of the mileage by registering the mileage at the gas station, the CO2 emission is based on the fuel data if present.

Influence of measurement inaccuracies and uncertainties in

scope 1 and 2

The foregoing information shows that the vast majority of CO2 emission is caused by use of fuel in the stationary equipments (574,7 ton of CO2) and the electricity consumption (6.773,8 ton of CO2). Therefore, it is important to accurately capture these emissions.

Scope 3: Other indirect CO2-emissions

CO2-compensation

There is no compensation for CO2 emissions. Available resources are used to make improve-ments within the production processes in the framework of the CO2-emission.

SCOPE 2:

The consumption data of the electricity is registered from billing information received from the energy suppliers of the different locations. Renolit has specified the information for electricity on the location Flevolaan. This information is considered as sufficiently reliable. It should be noted that most of the energy is used in the production processes.

The emission data of travel by private cars for business purpose is collected by employee decla-rations. The fuel type and engine classification of the applicable private cars are not registered.

De flight data for business purpose is collected by information from the travel organisation.

A complete emission inventory for scope 3 is currently outside the CO2 inventory. This report does therefore not include such an inventory.

YEAR 2, NR. 1 Page 8

Adjustments to historical year

For the first half of 2011 there are no adjustments to the base year.

Historical base year

The initial measurements in the context of the ISO 14064 standard have been done by Pipelife Nederland B.V. for the calendar year 2010. This year therefore serves as base year against which an increase or decrease in CO2 emissions is established.

Progress against reference year

Normalization measurements

The size of the CO2 emissions has a clear correlation with the scale of the activities carried out by the organization. For the comparison of the emissions in the reference year and future reported periods, standards are determined to normalize measurement results. For Pipelife, Kg product produced is the standard to scale the business activities. Based on the kg product produced the reported measurement results will be normalized.

In scope 1 the CO2 emissions par kg product produced are significantly lower in the first half of 2011 than in the base year 2010. This is due to an increase in the kg product produced and simul-taneously a small decrease in CO2 emissions. The reduction of CO2 emissions is due to a lower usage of fuel for stationairy combustion equipment and a significant reduction of cooling gasses. The litres of fuel for the own car park increased with 3,3%.

In scope 2 the CO2 emissions par kg product produced in the first half of 2011 is also lower than in the base year 2010. The reduction is less than the decrease in scope 1 because the increase in the kg product produced is accompanied by a rise in CO2 emissions in scope 2. This increase is caused by the electricity consumption in the first half of 2011, 5,4% higher than in the base year 2010. Also air travel has increased because the number of passenger by long haul flights in-creased with 30% in relation to the long haul flights in 2010.

Calculation models

Quantification methods

The quantification of raw materials to CO2 emissions is always calculated by registered volume units of the fuels used if present. The conversion of volume to emission values is straightforward and provides the most reliable comparison. In those situations where no volume units of fuel were available, the most reliable information available was used.

Electricity consumption is either taken based on calibrated meters and/or based on the invoices of the energy company. By applicable law, this is the most reliable source of information that is available.

Explanation for changes in the quantification methods

The measurement in 2011 H1 is the second measurement in the framework of the ISO 14064 standard. No adjustments in the quantitative methods are made against to the historical year.

Reduction targets

Based on this Carbon Footprint and the Energy Management System Pipelife defined meas-ures to reduce its CO2 emissions for the period 2010-2016 for scope 1 and 2.

The first target is to reduce the direct emissions per Kg product produced by reducing our loca-tions, replacements of own fleet by cars with a tag A or B and improve the involvement of our employees. Next to these reduction targets several investigations in the Netherlands and Ger-many are this moment carried out, for example in isolation improvements in production, Im-provement of heating and lighting in buildings. The outcome of these investigations is expected in 2012.

Reduction of the indirect emissions (scope 2) will be carried out by reducing the Electricity us-age in the production, replacement of lighting (sensoring) and office equipment and the per-sonal involvement of employees. The replacement of diesel forklifts by electric forklifts will have an increase the Electricity.

Because of longterm contracts for electricity Pipelife will first start to use green power for the distribution locations only. Possibilities for usage of green power on other locations are investi-gated. Currently this will lead to an reduction of 118,3 tonnes of CO2.

Based on the current quantitative information Pipelife wants to reduce its CO2-emissions for the period 2010 till 2016 with 4% per Kg product produced. The Kg product produced is the stan-dardization factor to make comparison possible between the reference period and the progress reports.
