Life cycle thinking
Life cycle thinking is an approach that emphasizes the assessment and minimization of environmental impacts at all stages of a product's life. This concept seeks to avoid shifting environmental burdens from one stage of the product's life to another. It also recognizes the importance of technological innovation in tackling environmental issues.
Corporations utilize this approach in the creation of environmentally friendly products. Consumers apply it in their mindful choices of products, and governments incorporate it into regulatory frameworks aimed at lessening environmental impacts. This strategy entails pinpointing crucial areas for impact reduction and enhancing consumer awareness regarding environmental concerns.
Approaches
There are many different approaches to life cycle thinking that all involve looking at life cycle-generated impacts and ways to minimize these impacts. An important component is the avoidance of burden shifting, which ensures that improvements in one stage are not achieved at the expense of another stage. Impact measurement focuses on decreasing environmental impact and resource use throughout all stages of a process.Life-cycle assessment
is a technique used to assess potential environmental impacts of a product at different stages of its life. This technique takes a "cradle-to-grave" or a "cradle-to-cradle" approach and looks at environmental impacts that occur throughout the lifetime of a product from raw material extraction, manufacturing and processing, distribution, use, repair and maintenance, disposal, and recycling.Life cycle management (LCM)
is a business approach to managing the total life cycle of products and services. It follows the life cycle thinking that businesses, through the activities they must perform, have environmental, social, and economic impacts. LCM is used to understand and analyze the life cycle stages of products and services of a business, identify potential economic, social, or environmental risks and opportunities at each stage and create ways to act upon those opportunities and reduce potential risks.Life cycle costing (LCC)
is the total cost analysis of a process or system. This includes costs incurred over the life of the system and is frequently used to find the most cost-effective means for providing goods and services.Design for the Environment
Program was created in 1992 by the United States Environmental Protection Agency and works to prevent pollution and reduce the risks pollution presents to humans and the environment. The main goals of the DfE are to promote green cleaning, recognize safer industrial and consumer products through safer product labeling, define best practices in production and manufacturing, and identify safer chemicals for these processes based on life cycle thinking.Product service system
are sets of marketable products and services that work together to fulfill a user's needs. This approach is a result of firms realizing that services in combination with products can provide higher profits and customer satisfaction than simply selling products alone. Firms that use PSS work to find ways to maximize the use of their product throughout its lifetime, using services to supplement its usage. PSS has been seen to have a smaller environmental impact than traditional business models, as the focus on services has led to a decrease in material production and consumption. This applies to life cycle thinking because it involves looking at the life-cycle cost of a product for a consumer and reducing that cost by providing services with the purchased good.Integrated product policy (IPP)
Integrated product policy works to minimize environmental degradation caused by products by looking at all phases of a product's life cycle to pinpoint where taking action is most effective. This also uses a cradle-to-grave approach when looking at a product's life. In addition, it is important that policies avoid burden shifting and do not decrease environmental emissions at one stage of development at the expense of another. Integrated policy measures used to act upon recommendations include economic instruments, substance bans, voluntary agreements, environmental labeling, and product design guidelines; the use of a variety of tools, rather than a single policy measure, is a central feature of an integrated approach.The European Commission issued a green paper on IPP on 7 February 2001. The European Parliament initially viewed the Commission's proposals as "interesting" but "unsatisfactory", and called for "a more exhaustive and more cohesive policy proposal" to be put forward. The Commission subsequently adopted a Communication on the subject on 18 June 2003, which was sub-titled "Building on Environmental Life-Cycle Thinking". The Communication listed potential roles to be played by several stakeholders: member states, industry, consumer organizations, environmental organizations and consumers.
Sectors
Agriculture
Life cycle thinking works to reduce the impact of the agriculture and food industry at all stages of food production. Cultural identity, health, lifestyle, and nutrition are addressed to ensure that decreases in emissions and environmental impact do not occur at the expense of consumer well-being.Manufacturing
A Product Life Cycle Analysis involves all production and service processes involved in the manufacturing of a product throughout the life cycle. This includes the production of materials needed to make the product. Since the manufacturing sector is a big emitter of pollutants and a user of natural resources, pinpointing areas in which to decrease environmental impact throughout the manufacturing process is a big part of life-cycle thinking.Energy
Drastic increases in atmospheric CO2 caused by burning fossil fuels have led to the search for alternative energy sources like biofuels and renewable energy sources. To analyze whether or not these alternative sources have overall less environmental impact than conventional energy sources, life-cycle analysis is needed. Life-cycle thinking is an intricate part of finding new energy sources that have an overall smaller impact on the environment.Waste management
Life-cycle thinking and analysis can help reduce the negative environmental impacts of waste generation and management. This includes looking at ways to reduce waste production, increase recycling, and dispose of waste in a more environmentally friendly way. This is complicated by differences in benefits and burdens in different geographical regions and the fact that effects usually occur over long periods. Furthermore, the benefits and burdens of different processes can occur in many different forms and can be difficult to identify, quantify and compare.Retail
often accounts for a significant portion of economies and thus can have huge implications in terms of environmental impacts. The life cycle of a product in retail would include the complete supply chain of the product, its use, and disposal or end-of-life treatment.Construction
There are many uses for life-cycle thinking in construction, especially in terms of construction waste and waste management. Finding better ways to recycle waste and prevent waste are important to reduce the negative environmental impact of the construction industry.For construction products in Europe, a standardized methodology for building assessment considering Environmental Products Declarations has been approved. The main standards are EN 15978 and EN 15804.
Transport
Finding alternative fuel sources is the biggest challenge to reducing negative environmental impacts in the transportation sector. Biofuels are becoming increasingly popular as an alternative to fossil fuels. Life cycle analysis can provide a fuller picture of the extent alternative fuel sources reduce emissions and overall environmental impact compared to conventional fuels.Services
Service industries play a big part in adding environmental burdens, especially in terms of greenhouse gas emissions generated by travel and tourist industries. The service industry is expected to play a larger part in the modern economy as "dematerialization", or the replacement of manufactured goods by services in many firms, plays a bigger role in the economy.Applications
There are multiple situations to which life cycle thinking can be applied, including the everyday life of consumers, businesses, and government policy. By applying life cycle thinking to multiple aspects of the community, consumers, businesses and governments can have a largely positive aspect on the environment. This is true even if the steps taken to apply life cycle thinking are small.Consumers
Consumers regularly make choices regarding products they would like to use, based on needs and different brands available. Due to several factors, the environmental impact of a product purchase may not be a deciding factor when it comes to choosing a product. Consumers may not be aware of the product's energy usage, questionable labor conditions that produced it, hazardous waste from production, impacts on the ecosystem, or pollution of air or water.Consumers can apply life cycle thinking in multiple different ways with regards to their product choices to reduce their impact on the environment. Many companies provide sustainability reports that consumers can read to educate themselves. By using life cycle thinking, consumers can choose a company with reduced environmental impacts.
Primarily, consumer usage has the largest impact on the environment throughout a product's life. By using life cycle thinking this impact can be reduced. This would require educating consumers to make better choices about product usage. This can come from the companies who provide the goods and services, from non-profit consumer awareness groups or government agencies. Consumer education starts with a self-assessment; for example, consumers can ask themselves what impacts they have while using the product and whether they can pursue more environmentally friendly alternatives. Consumers can educate themselves on how to become more sustainable themselves through life cycle thinking rather than relying on the efforts of companies and the government.
Businesses are responsible for many choices about their services and products each day. By applying life cycle thinking, businesses can recognize the potential impacts of their choices. They consider how each design and manufacturing decision has an effect on the environment and how they can make it more sustainable. Businesses not only take into consideration how the product is made, but also how the product will be used and disposed of by the user. Companies try to have more sustainable products by making products recyclable or reusable. The challenging part is balancing cost and sustainable choices. Life cycle thinking allows them to see the best sustainable options but is limited when it comes to pricing these choices. Life cycle thinking for businesses entails consideration of where to obtain raw material, how to manufacture the material, and transporting, distributing, using, and disposing of the product. By looking at all of these phases businesses make the best choices for themselves and the consumer for a lower impact on the environment.
