What is your handprint? Spread a positive message about environmental impacts


Environmental impacts play a key role in business nowadays, both in product design and communications on business activities. These are traditionally measured using quantities, such as emissions and resource consumption, which companies try to minimise. However, our activities can also have a positive impact on the environment.

Aiming for a smaller customer footprint

The calculation of footprints and their use in product design, B2B and B2C communications, and in support of strategic decision-making, are now established in industry. This is a good thing. An approach based on life cycle thinking is important to avoiding sub-optimisation and seeing the wider, overall impact of solutions. The inclusion of impact assessments in the product development phase, in particular, has markedly increased the market share of products that are more environmentally friendly than their predecessors. Decisive choices are made during the product design phase, on issues such as raw materials, production processes and recyclability. Each phase consumes energy and resources and either directly or indirectly generates various types of emissions and waste resulting an environmental footprint.

Many companies are already seeking to reduce their own footprint. At the same time, more and more companies are developing products or processes aimed at reducing the footprint of the customer’s product or service. In such cases, their activities also have a positive environmental impact.

Let’s take an example: Company X develops a more energy-efficient solution than its competitors and launches it on the market. A carbon handprint is created when another actor applies this solution and thereby reduces its own footprint. However, measuring – and communicating on – the related impact has so far been difficult, and companies have been in sore need of a solution.

Environmental handprint can now be calculated

VTT has accepted the challenge: it is developing a carbon handprint calculation method, as well as guidelines on positive environmental impact assessment and communications, alongside Lappeenranta University of Technology (LUT).

A carbon handprint can be created in many ways, such as through lower material and energy consumption, reduced emissions and waste, or improved product performance and lifetimes. To ensure that the method takes account of the range of various handprint-forming , methodological development is conducted in cooperation with a group of companies.

Case studies include AM Finland, Biolan, Innofive, KONE, Neste, Nokia and Paptic. We also cooperate with the international organisations involved in developing the handprint concept. These include the CSCP in Germany (which operates in association with the Wuppertal) and Harvard University in the USA.

However, VTT and LUT are working at a more tangible level; we intend to publish the first practical handprint guidebook next summer. Companies can use this to evaluate and communicate on the positive environmental impacts of their products.

Sustainability assessment requires cooperation along the life cycle – Knowledge exchange benefits all actors

Sustainability assessment addresses the interlinkages between economic, environmental, and social dimensions. These questions can be challenging but we have to try our best, as there is an urgent need to cut greenhouse gas emissions, to reduce material and energy consumption, and to promote a more even distribution of well-being globally. In order to make it happen, it is also necessary to consider the economic impacts.

Sustainability assessment tackles concrete questions related to measuring the impacts of products and services

Sustainability assessment is a topical and sometimes tricky question for multinational companies. Within the European process industries, life cycle-based sustainability assessment methods are commonly used to tackle internal and external questions related to the environmental impacts of products and technologies, and for the purposes of product development.

Although a lot of information about the manufacturing processes is collected on a regular basis, gathering and tailoring this information for the purposes of a carbon footprint or a water footprint might require a lot of manual work, sometimes even detective skills.

Life cycle assessment is a well-established method for sustainability assessment

Life cycle assessment evaluates the environmental impacts of a product covering the whole life cycle, from raw material acquisition to recycling or disposal. The aim of this comprehensive approach is to avoid shifting environmental impacts from one life cycle stage to another. Currently, the use of life cycle assessment is emphasized within European Environmental Policy. Life cycle thinking is also at the core of the European Commission’s Circular Economy Action Plan.

Current practices and future development needs related to use of life cycle-based sustainability assessment methods in process industries were studied within the SAMT project.[1] The findings of the project reveal that life cycle-based assessment methods are considered useful and important for addressing different kinds of questions related to the sustainability of products and services. There is also a growing need for and interest in integrating the principles of sustainability assessment and life cycle thinking within daily decision-making processes.

Assessment methods and tools need to be adapted to the evolving needs of users

The forerunner companies have already made a lot of efforts to integrate environmental goals within all their activities. Yet in order to make it more practical and widespread, there is room for further development of the methods and supporting tools. One of the bottlenecks currently hindering the wider use of these methods is the availability of high-quality data. Most companies can, with some effort, acquire information about their own processes, but a common challenge is handling the processes taking place either upstream or downstream of their own activities.

New data-needs arise every time a new topic enters the sustainability agenda: While dedicated databases for addressing environmental aspects are already available, there is a growing need for social and economic data.

Cooperation is required for data acquisition – and for dealing with technical challenges

Including the preceding and subsequent life cycle stages and processes is usually of crucial importance in making a reliable assessment. In practice, this requires receiving more or less detailed input–output data from suppliers and customers. Available life cycle databases may provide some help here, but not all the required data is necessarily found from the databases.

Additionally, compiling data acquired from different sources usually requires a lot of manual work and modifications, which is slow and increases costs and the risk of errors. Challenges may also occur due to the technical incompatibility of different data formats and software versions. Thus, expertise in sustainability might not be enough – extra support from technical experts might be needed.

Sharing creates learning

Improved understanding of the product life cycle is useful to all actors: increasing material or energy consumption may sometimes be reasonable at the beginning of the life cycle if these choices enable lighter processes in the subsequent life cycle stages.

The experience gained in the SAMT project pointed out that discussion and sharing of experiences and learning between actors who deal with similar questions is inspiring and may help solve some of the challenges faced. While there are differences between the needs of individual sectors and companies, many of the practical bottlenecks are common to all actors. Discussions with suppliers and other members of the value chain was one of the good practices recommended for data collection.[3]

Different technical solutions may also be found for sharing confidential data either directly or in an aggregated form. However, there is also a clear need for new tools or technical solutions for collecting, handling, and sharing data.

Why bother?

The SAMT project reveals that although no perfect method or tool for sustainability assessment currently exists, existing methods are already capable of addressing many aspects of sustainability, and providing useful information to support decision-making in different contexts. Sustainability assessment is a process that is never completely finished, but along the way it provides us with important information to guide our actions.[4]

Sustainability researchers and method developers are encouraged to consider user perspectives and the practical issues faced when implementing the methods and tools in practice. These include the need to operate with limited data and resources. Industrialists are encouraged to be active in testing available methods and tools, in sharing their experiences, and discussing with stakeholders so as to increase knowledge of relevant sustainability aspects within and across value chains.

Beware of greenwash! Reliable indicators exist for sustainable innovations

Now, at the beginning of Sustainable Development Week, is the ideal time to recount how we can best ensure the sustainability of innovations and projects. Companies can unintentionally slide into greenwashing which, in today’s business environment, can jeopardise an entire innovation breakthrough. Scientifically approved methods of assessing sustainability help firms to communicate transparently on environmental impacts.

The rise in temperatures is forecast to accelerate most in the northern hemisphere’s land areas during winter. According to some estimates, current emission trends will lead to warming by up to six degrees in Helsinki. Few Finns are enthused by a vision which sees us ‘enjoying’ temperatures hovering around zero from October to May. Only the light levels will distinguish April from December. And this is the most minor of issues compared to the effects of global warming on world food production, water sufficiency, the distribution of insects and plants, health-related problems and other issues related to extreme phenomena.

The challenge is huge but action is being taken

The mitigation of greenhouse gases and taking other action promoting sustainable development are now among the key strategic objectives of more and more states and companies. A total of 17 international objectives are listed in the UN’s sustainable development action plan for Agenda 2030. These goals include global themes such as clean water and sustainable production. The aim is to limit the global average temperature rise to a maximum of two degrees, in accordance with the Paris Climate Agreement.

During European Sustainable Development Week, we will explore the theme of the aforementioned Agenda 2030. Finland is implementing the programme in a number of ways. You can make your own commitment to take action via the Prime Minister’s Office, and challenge others to do so.

Companies still ahead of governments in taking practical actions

Innovation and risk-taking are more effective than regulation. Change is accelerating via the circular economy, cleantech and the bio economy, in which VTT is playing a major role as a developer of solutions. However, it is easy to be misled, since not all businesses that increase recycling or use biomaterials are sustainable. The processing of side and waste streams for reuse or the manufacture of biomaterials can require complex and energy-consuming processes, energy-intensive or harmful chemicals, or long transportations, and the availability of raw materials is not always guaranteed. A growing group of stakeholders, including national leaders, financiers and corporate customers are becoming more interested in environmental and social impacts alongside economic issues.

How is sustainability measured?

Science-based indicators are needed when assessing and communicating on the real impact of products and business models. These indicators include life cycle and system-based methods of measuring environmental impacts, such as LCA (life cycle assessment), which examines the overall effects. This approach ensures that sub optimisation does not lead to the shifting of problems from one part of the value chain to another, or exchanging them for others. It also enables us to communicate transparently on the impacts and avoid greenwashing.

LCA is already widely required in product development and communications. The next Horizon PPP-SPIRE call demands the transparent sustainability assessment for all projects, based on life cycle thinking and the most standardised methods possible. The European Commission is preparing an LCA-based guide for calculating product environmental footprints, or PEFs, in order to create an internal market for green products. The Commission recommends the future use of the footprint when measuring the environmental impact of products and in corporate communications.

Companies using LCA in product development will benefit at the customer interface, where responsibility has become a key issue and knowledge of the entire supply chain is important. For example, such companies find it easier to participate in the newest way of demonstrating corporate responsibility, the Science Based Target (SBT) initiative, and to define emission reductions in their operations accordingly. Targets under the SBT initiative are based on the emission reductions set by the Paris Convention on Climate Change and require consideration of the entire value chain. Almost 300 companies are committed.

Handprint as well as footprint

A range of indicators are needed for different situations and industries, to ensure that account is taken of the key aspects of sustainability. For over 20 years, VTT’s experts have been pioneers in developing LCA-based assessment methods and indicators. These methods are being developed further as information and the need for it increases. For example, we are launching a so-called handprint alongside various kinds of footprint. Due to their manufacturing processes, all products have an impact on the environment, i.e., a footprint, which should be minimised. In addition, many products can be used to reduce the environmental load elsewhere (e.g., water treatment chemicals), in which case the product also has a positive environmental impact. To enable the measurement and communication of such impacts, VTT has begun a Tekes development project to define an environmental handprint.

We are applying sustainability assessment methods to evaluating solutions at the product development stage, as well as finished products and their development potential. We will be delighted to help you if you are seeking the right indicators and intend to refine them for a clearer view of sustainable development.

Energy efficiency is the key component of sustainable development in cities


The UN Habitat New Urban Agenda was released a few weeks in Quito, Equador. The task to write a new urban agenda has not been easy, given that pre-conditions and interests are different in different UN countries. At the same time, there is an urgent need to act in favour of sustainable development in cities.

The striking fact is that urban settlements covers roughly 2.7% of the surface area of the globe, but consume 70% of resources and hence produces 75% of CO2 emissions. Moreover, we face many challenges if we are to transform our cities into healthy, safe and comfortable living and working areas.

Starting from these pre-conditions, the New Urban Agenda for the first time highlights the importance of energy. As is well-known, energy production is the main source of CO2 emissions and air quality problems in cities. Energy is needed in cities for transport, heating, cooling, lighting as well as for water and sanitary systems. We also need energy to run equipment and appliances. To transform ourselves into low carbon society, we need to de-carbonise our energy production, but also, very importantly, we need to use energy more efficiently. Energy that does not need to be produced is the most environmental friendly. Energy efficiency is not only beneficial in preventing pollution but is also a key component for resilient cities. Energy efficiency entails reducing overall demand and more importantly reducing peak demand. In combination with smart technologies, demand can be controlled based on self-learning and adaptive algorithms to reduce and shift the demand even more efficiently without compromising users’ well-being, but rather in ways that can also further enhance well-being.

Smart cities and efficient resources

In addition to energy, the concept of smart cities was for the first time raised onto the agenda. The concept of smart cities is quite unique, since it is applicable both to industrialised cities/districts and to developing economies. The benefit of smart cities is that by using easy-to-install and adaptable sensors and self-learning control algorithms, existing infrastructure can be made more efficient. Moreover, new methods allow for generating urban services more efficiently in developing countries, without heavy and costly infrastructure requirements. Good examples for this are the implementation of renewable energy sources for cities and communities. In addition, smart communications enable citizen engagement and ownership within their own living areas, which evidently improves the perceived living quality and attractiveness of the area.

Smart systems enable us to use our resources more efficiently. This can be done by using and combining data from different sources. Currently, in modern buildings, there are typically over 20 000 data points, and hence in cities there exists an unimaginable amount of data; it is evident that no-one has the capacity to process all the data. We need, therefore, smart self-learning and predictive systems to make the most of the data available. One of the leading principles in smart cities is to enrich data to create meaningful information that supports our decision-making and helps in making our everyday lives run smoothly and that helps us to achieve environmental sustainability. More importantly, this saves time for the most important things in our lives.
