Currently, there is a lack of methods for calculating and communicating the beneficial environmental impacts of products and services. To fill this gap, this report presents a new approach for calculating the positive climate impact of a product or service – the carbon handprint. The purpose of the carbon handprint approach is to assess and communicate the positive climate impact of products and services, thereby incentivizing environmentally responsible practices and enabling informed choices.The core of the suggested approach involves comparing the carbon footprint of an improved product with the carbon footprint of the baseline product, and subsequently calculating the reduction in greenhouse gas emissions that can be achieved by using the improved product. The carbon handprint approach is founded on the standardized life cycle assessment methodology for footprints and provides a framework for identifying climate impacts in the actual operational environment. Methodological development is based on seven industrial case studies, in which carbon handprints of different products, services, and technologies are assessed. These case studies, carried out with AM Finland, AO-allover, Biolan, KONE, Neste, Nokia, and Paptic, are presented in this report. Organizations can use carbon handprints to quantify the greenhouse gas reductions that their customers can achieve by using certain products. The carbon handprint can thus serve as a powerful tool in communications and marketing. By conducting carbon handprint assessments, a company can also find out how their product qualifies in comparison to baseline products. Carbon handprints can therefore also support decision-making and lifelong product design.Through further research, the carbon handprint methodology can be adjusted to also cover other environmental impacts. Aspects to consider include different spatial scales of impacts and quantitative and qualitative aspects of material and energy flows. Quantitative and quantifiable qualitative environmental impacts could be the starting point for extension of the methodology to other environmental impacts. A more extensive view of environmental handprints could help avoid trade-offs between beneficial impacts.

- Abstract
A large part of the lifecycle environmental impacts of a product are determined at the design stage, why The EU Eco design Directive’s potential for application to non-energy related themes has come under the spotlight in recent years with Nordic countries at the forefront. In this report potential eco design requirements that can be drawn up for non-energy-related products are in focus. Textiles are here used as an example, and a light application of the approach has subsequently been applied to the furniture sector. Clothing and home textiles were chosen due to significant wastage in the value chain due to fast fashion, dropping quality and relatively low repair and reuse rates.The project was initiated and financed by the Nordic Council of Ministers and led by its Working Group for Sustainable Consumption and Production. A separate Policy Brief (ANP2018:739) is also published.

- Abstract
Goal and Background: The treatment of allocation in the descriptive LCA of wood-based products has been discussed for a long time and different solutions have been presented. In general, it is accepted that the influence of different allocation procedures on the results of LCA of wood-based products can be very significant. This paper is a result of the Cost Action E9 ‘Life cycle assessment of forestry and forest products' and represents the experience of involved Cost E9 delegates. Objective: Wood is a renewable material that can be used for wood products and energy production. Consistent methodological procedures are needed in order to correctly address the twofold nature of wood as a material and fuel, the multi-functional wood processing generating large quantities of co-products, and reuse or recycling of paper and wood. Ten different processes in LCAs of wood-based products are identified, where allocation questions can occur: forestry, sawmill, wood industry, pulp and paper industry, particle board industry, recycling of paper, recycling of wood-based boards, recycling of waste wood, combined heat and power production, landfill. Methodology: Following ISO 14 041 a step-wise procedure for system boundary setting and allocation are outlined. As a first priority allocation should be avoided by system expansion, thus adding additional functions to the functional unit. Alternatively, the avoided-burden approach can be followed by subtracting substituted functions of wood that are additionally provided. If allocation cannot be avoided, some allocations methods from case studies are described. Conclusions: The following conclusions for allocation in LCA of wood-based products are given. 1) Avoid allocation by expansion of system boundaries by combining material and energy aspects of wood, meaning a combination of LCA of wood products and of energy from wood with a functional unit for products and energy. 2) Substitute energy from wood with conventional energy in the

The concept of handprint has been introduced to measure and communicate the positive changes of actions and the beneficial impacts created within the life cycle of products, services, processes, companies, organizations or individuals. A handprint of a product can be created either by preventing or avoiding negative impacts (footprints), or by creating positive benefits. The handprint of a company considers the footprint of the company itself, but also the positive changes the company influences to impacts of individuals or other companies.

Alma media ordered a research study from VTT and Centre for Sustainable Communications (CESC) at KTH, in order to evaluate the environmental performance of specific Alma Media products. The report covers the results of the life cycle assessments for printed newspapers; Aamulehti, Iltalehti and Kauppalehti as well as online newspapers; Aamulehti.fi, Iltalehti.fi and Kauppalehti.fi. With the help of a life cycle assessment the potential environmental impacts related to a defined product life cycle is evaluated, taking into account raw material acquisition, production, use, and endof-life treatment. Thus, various kinds of environmental impacts were considered.The results indicate that the environmental performance of printed and online versions of Alma Media’s newspapers includes different types of environmental impacts, and that these are distributed differently in the value chain and geographically. The majority of the impacts of printed newspapers occur from paper and printing manufacturing, which are located in Finland. On the other hand, environmental impacts related to online newspapers are to a large extent dependent on the manufacturing of electronic devices used for reading the online content. These impacts occur in other countries and at the suppliers not directly related to Alma Media. With few readers of the online versions the content production may also be a considerable part of the overall potential environmental impact. The actions to take towards improvements will need to be different related to the value chain. Furthermore, Alma Media as a media company can have a key role in sharing environmental information in order to improve user practices and stakeholder practices along the value chain. The study covered a number of environmental impacts, which was important because the environmental impacts for online and printed newspapers were clearly different. The study also pointed out the importance in being careful when assessing impact categories where there may be substantial data gaps and where there are greater uncertainties related to the assessment of impacts, e.g. toxicity impact categories. Comparisons between print and online versions are not simple, as print and online versions provide different types of information and the readers use them in different ways. Furthermore, the printed and online newspapers from Alma Media may not replace each other, but rather complement each other which can mean adding up environmental impacts from printed and online versions. The functional unit chosen is very decisive regarding the environmental performance of printed and online media, if they are to be related to each other. Using different kinds of perspectives through functional units gives more information and increased knowledge. QC 20130710

In the media sector, recently new means of distribution, new platforms for accessing media and consequently new media products have been introduced. With new products potential environmental impacts related to activities of media companies are changing. Finnish media publisher Alma Media commissioned an LCA study in order to learn more about environmental impacts related to their mature and emerging products. Based on this, the current paper aims to present potential environmental impacts related to printed and online newspapers, focusing on their differences and challenges in assessing, comparing, communicating and acting on the results. Three newspapers are studied as cases, covering upstream printing house supply chain, printing house activities, delivery to readers and final disposal for print versions; electronic storage and distribution, the relevant share of electronic devices manufacturing and disposal and electricity needed for downloading and reading for online versions; content production for both. Mainly generic data was used for online products assessment, since specific data were not available. The specific data for the more mature print products were detailed but less comprehensive than generic. The implication is increased uncertainty and difficulties in communication of results. Environmental performance of both printed and online newspapers is dependent on various characteristics of the newspaper and its readers, including e.g. format and number of pages for print versions, and type of device used and its total use, size of content download and reading time for online versions. User practices may be changing as emerging products get more mature, which will influence environmental performance. Print and online versions give rise to different types of environmental impacts and the distribution of impacts in the life cycles differ. Printed newspaper impacts largely occur in the printing house supply chain and in delivery to readers, whereas online newspapers impacts are mainly connected to the electronic devices supply chain, and to some extent electricity used for reading and distribution. Impacts of printed newspapers studied occur more locally with paper manufacturing and printing located in Finland. Impacts related to online versions largely occur in other countries. Also, new value chain actors are involved, which are not directly related to the media company. Different actions for improvement may be necessary for emerging media products, as well as new types of collaborations. Comparison of online and print versions is not straightforward as different benefits are provided and reader practices differ. Although emerging media products may be considered substitutes for print counterparts, this is not necessarily the case. The choice of functional unit of assessment proved crucial for the comparison. Different functional units were used (one year, one reader and week, one reading hour). Comparing print and online versions Alma Media online newspapers showed lower environmental impacts than their print versions per year and also per reader and week. However, impacts per reading hour were lower for printed newspapers in some cases. Using different kinds of perspectives, e.g. through different functional units, gives more information and increased knowledge. Complexity in assessing, comparing, communicating and acting on emerging media products was experienced in this study. Further studies and action need to be taken. QC 20121221

SDG 13 - Climate Action - Abstract
Discussion about the impacts and consequences of climate change has aroused interest in the carbon emissions that are associated with the purchased products. In the methodology development, the inclusion of biogenic carbon has turned out to be problematic. The problems with including biomass carbon are mainly related to forest carbon balance and some methodological issues concerning carbon storage in products. There are several open questions that have to be solved, such as the time frame used in the carbon footprint calculations. Before a generally accepted methodology is available, several varying approaches are applied, depending on who is performing the calculations and what their goal and scope are. The effect of wood raw material harvesting on the forest carbon balance can be calculated in various ways. Three different approaches are presented in this paper. In the first approach, it is claimed that sustainable forest management ensures that the same amount of carbon taken out from the forest is absorbed again by the forest growth. The opposite way is to calculate the lost carbon stock and allocate it to products. The third approach allocates the net carbon sequestration through net forest growth to forest products. Guidance concerning carbon storage in products exist and they are discussed in this paper. The challenges of including the forest carbon balance are expressed with the case calculation examples.

- Abstract
The rapid and continuous development of information and communication technology (ICT) in society today is providing new means for various societal activities. To facilitate that new ICT solutions reduce environmental impacts and bring social improvements the potential impacts of those new solutions should be assessed. One way of making environmental assessments is Life Cycle Assessment (LCA). This paper presents and discusses challenges in assessing, comparing, communicating and acting on the results of an LCA of traditional media products and of new ICT solutions for media products, based on case studies of three newspapers in their printed and online versions. The case studies revealed the complexity in assessment and comparison of online and printed newspapers due to differences in functions and characteristics, choice and availability of data (specific and generic data, data gaps and quality), methodological choices (functional unit, allocation, scope) and assumptions on reader profile. Often no single answer can be given regarding the best option from an environmental perspective, leading to challenges in communicating the results to different stakeholders. A particular challenge is how to combine easily communicated messages with robust, transparent background information., QC 20150122
