8.21 Environmental Justice

Environmental impacts are not always distributed equally.

Resource extraction may affect particular communities.

Pollution may be geographically concentrated.

Digital infrastructure may require significant water or electricity resources in particular locations.

Environmental evaluation should therefore consider distributional effects.

This links environmental evaluation directly with the social dimension of AMTEF.

Environmental justice extends environmental evaluation beyond the question of total environmental impact. Two technologies may generate similar aggregate environmental burdens while distributing those burdens very differently across populations, regions and communities. An environmentally responsible assessment should therefore consider not only how much environmental pressure is created but also where it occurs, when it occurs and who experiences its consequences.

Resource extraction provides an important example. Minerals and materials required for batteries, electronics, renewable-energy systems and digital infrastructure may be extracted in particular geographical regions. The environmental consequences of mining can include land disturbance, water consumption, waste generation, habitat disruption and pollution. The economic benefits of the resulting technology, however, may be distributed across international markets. Environmental evaluation should therefore recognize the geographical separation that can exist between the location of environmental burdens and the location of technological benefits.

The same principle applies to manufacturing. Industrial production may generate air emissions, wastewater, noise and solid waste in particular communities, while the resulting products are consumed elsewhere. A lifecycle assessment can identify the aggregate environmental burden, but environmental justice requires additional attention to its distribution.

Digital technologies create similar questions. Data centres may require substantial electricity and, depending on their cooling systems and local conditions, significant quantities of water. The services generated by those facilities may be used by people across countries and continents, while the physical environmental requirements are concentrated at particular locations. The environmental evaluation of digital technology should therefore consider the geographical concentration of infrastructure.

Environmental justice also involves temporal distribution. Some technologies may provide immediate economic benefits while creating environmental liabilities that emerge over decades. Waste disposal, contaminated sites, hazardous materials and long-term ecosystem degradation can transfer environmental burdens from current populations to future generations.

This introduces an intergenerational dimension to environmental evaluation. A technology should not be assessed solely according to the benefits and costs experienced during the period in which it is economically useful. Its long-term consequences should also be considered.

Environmental justice also involves procedural dimensions. Communities affected by major technological infrastructure may have legitimate interests in how decisions are made, what information is disclosed, how risks are communicated and whether affected stakeholders have opportunities to participate. Environmental evaluation can therefore include questions concerning transparency, consultation, accountability and access to information.

Vulnerability is another important consideration. Environmental burdens may have different consequences for different populations depending on their economic circumstances, geographic location, infrastructure access and dependence on natural resources. A disruption to water availability, for example, may have very different consequences for a community with limited alternatives compared with an organization that can purchase water from another source.

Environmental justice should therefore be incorporated into technology evaluation through questions concerning distribution.

Who receives the benefits?

Who bears the environmental costs?

Where do the environmental impacts occur?

When do those impacts occur?

Which communities are most exposed?

Which populations have the greatest capacity to adapt?

Who participates in decision-making?

What mechanisms exist for mitigation, compensation, remediation or accountability?

These questions do not replace quantitative environmental assessment. Instead, they complement it. Aggregate indicators such as total carbon emissions, total water consumption or total material use can conceal important differences in distribution. Environmental justice therefore adds a social and geographical dimension to environmental measurement.

The principle is particularly relevant to large infrastructure projects, mining, energy systems, transportation networks, manufacturing facilities, waste-management systems and digital infrastructure. Technology evaluation should recognize that environmental sustainability is not simply a matter of reducing aggregate environmental indicators. It also involves ensuring that environmental risks and benefits are considered fairly across affected populations.

Within AMTEF, this connects environmental evaluation with social responsibility, governance, ethics and stakeholder analysis. Environmental performance and social consequences cannot always be separated because environmental conditions directly affect human wellbeing.

Environmental justice therefore reinforces the principle that technology should be evaluated not only according to what it produces, but also according to where its environmental consequences occur, who experiences them and how decisions concerning those consequences are made.

8.22 Climate Resilience

Technology should not only be assessed for its environmental impact.

It may also need to be assessed for its resilience to environmental change.

Questions include:

Can the technology operate under higher temperatures?

Can infrastructure withstand extreme weather?

Does water scarcity affect operation?

Does climate change affect supply chains?

This creates a distinction between:

Environmental impact

and

Environmental resilience.

Both should be evaluated.

Environmental impact concerns the effects that a technology has on the natural environment.

Environmental resilience concerns the capacity of a technology, organization, infrastructure system or technological network to continue functioning under changing environmental conditions.

The distinction is important because a technology can have relatively low environmental impacts while remaining highly vulnerable to climate-related disruption. Conversely, a technology may be relatively resilient to environmental change while generating substantial environmental impacts. Sustainable technology assessment should therefore examine both dimensions.

Climate change can alter the operating conditions under which technologies were originally designed. Higher temperatures may reduce equipment efficiency, increase cooling requirements, accelerate component degradation and create safety challenges. Extreme rainfall may damage infrastructure, while flooding may interrupt transportation networks, electricity systems, manufacturing facilities and data centres. Drought can reduce water availability for industrial processes, agriculture, energy generation and cooling.

Supply chains are also vulnerable. Technologies may depend on minerals, components, semiconductors, chemicals or specialized manufacturing processes originating from geographically concentrated locations. Climate-related events can interrupt transportation, production and resource availability. A technology may therefore be technically reliable under normal operating conditions but vulnerable because its supply chain cannot maintain continuity during environmental disruption.

Water availability is another important resilience factor. Technologies that depend heavily on water may face increasing operational risks in regions experiencing drought or changing precipitation patterns. Data centres, power-generation facilities, manufacturing plants and agricultural technologies can all be affected by water constraints.

Energy systems provide another example. Renewable-energy technologies can reduce dependence on fossil fuels, but their performance may also depend on environmental conditions. Solar generation depends on solar availability, while hydropower depends on water availability. Wind generation depends on wind conditions. A resilient energy system therefore requires consideration of variability, storage, transmission, grid flexibility and complementary energy resources.

Infrastructure resilience should also be considered. Roads, bridges, telecommunications networks, electricity systems, buildings and industrial facilities may be exposed to flooding, storms, heat, landslides, drought and other environmental hazards. Technology assessment should examine whether infrastructure has been designed for the environmental conditions it is likely to encounter throughout its expected lifetime.

This introduces the concept of future operating conditions. Traditional technology assessment often evaluates performance using historical environmental conditions. Climate resilience requires consideration of whether those historical conditions remain appropriate for future decision-making.

Scenario analysis can support this assessment.

A technology may be evaluated under current environmental conditions.

The same technology may then be evaluated under higher temperature conditions.

It may also be evaluated under increased precipitation variability, water scarcity, extreme weather events or supply-chain disruption.

The objective is not to predict one specific future with certainty. Instead, scenario analysis allows organizations to understand how technological performance may change under different plausible environmental conditions.

Resilience also involves recovery. A resilient technology or infrastructure system should not only withstand disruption but should have the capacity to recover functionality after disruption. Recovery may depend on spare components, maintenance capabilities, alternative energy supplies, backup systems, skilled personnel, communications infrastructure and organizational preparedness.

Redundancy can therefore become an important element of technology resilience. Systems that depend entirely on one component, one supplier, one geographic location or one energy source may be more exposed to disruption than systems with appropriate alternatives. However, redundancy can also increase material, energy and financial requirements. The evaluator should therefore examine resilience measures alongside their lifecycle consequences.

Adaptability is another important dimension. Technologies that can be upgraded, repaired, reconfigured or adapted may remain useful under changing conditions for longer periods. Modular design, interoperable components, software updates, repairability and flexible infrastructure can contribute to technological resilience while potentially reducing premature replacement and waste.

Resilience should also be assessed at the organizational level. A technology may be technically resilient while the organization operating it lacks the resources or capabilities required to maintain it during disruption. Environmental resilience therefore depends on the interaction between technology, infrastructure, people, institutions, supply chains and governance arrangements.

This can be represented conceptually as:

Environmental change → technological exposure → operational vulnerability → disruption → organizational response → recovery → adaptation.

Each stage provides an opportunity for assessment and intervention.

Climate resilience also has an important relationship with lifecycle thinking. A technology expected to operate for twenty or thirty years should be assessed against the environmental conditions that may occur during that period rather than only the conditions present at the time of installation. Long-lived infrastructure requires particularly careful consideration because decisions made today can determine environmental vulnerability for decades.

The evaluator should therefore consider both the environmental footprint of the technology and its capacity to function within a changing environmental context.

Environmental impact asks:

What environmental consequences does the technology create?

Environmental resilience asks:

How well can the technology continue to function as environmental conditions change?

The two questions are complementary.

A technology may reduce emissions but fail under increasing heat.

A technology may conserve water but depend on a climate-sensitive supply chain.

A technology may have low operational emissions but require materials whose availability is vulnerable to environmental disruption.

A technology may improve resilience for one organization while transferring environmental risks to another location or community.

For this reason, climate resilience should be treated as an integrated component of technology evaluation rather than as a separate environmental issue. The objective is not simply to identify technologies with lower environmental impacts, but to understand whether technological systems can remain effective, responsible and sustainable under changing environmental conditions.

Within AMTEF, this creates a broader environmental assessment framework in which technology is evaluated according to both its environmental footprint and its capacity for long-term adaptation. Environmental responsibility therefore requires two complementary questions: what effect does the technology have on the environment, and how will environmental change affect the technology?

Both should be evaluated.

8.25 Chapter Research Questions

Why is lifecycle assessment important for emerging technologies?

Lifecycle assessment is important because the environmental consequences of an emerging technology may extend far beyond the stage at which the technology is used. Manufacturing, raw-material extraction, transportation, infrastructure requirements, energy consumption, maintenance, replacement, reuse, recycling and disposal can all contribute to the overall environmental profile of a technology. Emerging technologies may appear environmentally beneficial when only their operational performance is considered, while their broader lifecycle impacts may reveal additional resource requirements or environmental burdens. Lifecycle assessment therefore provides a more comprehensive basis for determining whether an apparent environmental improvement represents a genuine system-level improvement.

The question also requires consideration of the relationship between environmental benefits and environmental costs. A technology may reduce one environmental impact while increasing another. Lifecycle assessment helps identify these potential burden shifts and allows the evaluator to consider environmental performance across multiple stages rather than focusing on a single point in time.

How should environmental impacts be assessed when data are incomplete?

Incomplete data are common when technologies are new, rapidly developing or being deployed at limited scale. Environmental assessment in such circumstances may require estimated values, secondary datasets, engineering assumptions, scenario analysis, sensitivity analysis and comparisons with analogous technologies. The evaluator should distinguish between measured information, estimated information and assumptions and should document the basis for each.

Uncertainty should not automatically prevent environmental evaluation. Instead, uncertainty should become an explicit part of the assessment. The evaluator should determine which assumptions have the greatest influence on results and examine whether alternative assumptions substantially change the conclusions. Where uncertainty is particularly high, results may be more appropriately expressed as ranges or scenarios rather than as a single precise value.

The research question therefore concerns not only how to calculate environmental impacts but also how to communicate the reliability and limitations of those calculations.

What is the difference between operational and lifecycle environmental impact?

Operational environmental impact refers to environmental effects generated while a technology is being used. These may include electricity consumption, fuel consumption, water use, emissions, waste generation and other operating requirements.

Lifecycle environmental impact is broader. It includes environmental consequences associated with raw-material extraction, processing, manufacturing, transportation, installation, operation, maintenance, replacement, reuse, recycling and final disposal.

The distinction is particularly important when technologies have low operational emissions but significant upstream environmental requirements. Electric vehicles, renewable-energy technologies, batteries, digital infrastructure and electronic devices provide examples in which manufacturing and material requirements can contribute substantially to total lifecycle impacts.

The research question therefore encourages evaluation beyond the point of use. It asks whether the environmental performance observed during operation remains positive when the complete lifecycle is considered.

How should technology evaluation incorporate circular-economy principles?

Circular-economy principles encourage technologies and products to remain useful for as long as possible and to retain the value of materials and components through reuse, repair, refurbishment, remanufacturing and recycling. Technology evaluation should therefore consider whether a technology has been designed to support these activities.

The assessment can consider product durability, repairability, modularity, upgradeability, material recovery, component replacement, recycling infrastructure and the availability of secondary markets. Software support can also influence technological longevity because hardware that remains physically functional may become obsolete if software updates or security support are discontinued.

Circularity should not, however, be assumed simply because a technology is recyclable. Recycling itself consumes energy and resources, and recovery rates may vary significantly between materials and locations. The evaluator should therefore examine the actual circular pathway rather than treating recyclability as an automatic environmental benefit.

This research question also concerns the relationship between technological design and waste prevention. A technology designed for a longer useful life may avoid the environmental impacts associated with repeated manufacturing and replacement. Circular-economy evaluation can therefore become an important component of lifecycle environmental assessment.

How do geographical differences influence environmental evaluation?

Environmental impacts are strongly influenced by location. Electricity systems differ in their generation mix, water availability varies geographically, transportation distances differ, waste-management systems have different capabilities, and environmental regulations vary across jurisdictions. The same technology can therefore have different environmental outcomes in different locations.

Climate conditions can also influence performance. Cooling requirements, heating requirements, solar availability, rainfall, temperature and water availability can affect both energy consumption and operational efficiency. Geographic conditions can also influence the vulnerability of infrastructure to flooding, drought, storms, heat and other environmental hazards.

Supply chains introduce another geographical dimension. Raw materials may be extracted in one country, processed in another, manufactured elsewhere and eventually consumed in a completely different market. Environmental evaluation should therefore consider the geographical distribution of lifecycle activities rather than treating the technology as though it exists in a single location.

Geographical differences also influence environmental justice because environmental burdens may be concentrated in communities that are geographically distant from the consumers who benefit from the technology. Environmental evaluation should therefore consider both spatial distribution and aggregate environmental performance.

How should environmental trade-offs be communicated?

Environmental trade-offs should be communicated transparently and in a manner that allows decision-makers and stakeholders to understand both benefits and burdens. A technology should not be described simply as environmentally positive or environmentally negative when the evidence demonstrates a more complex relationship.

Communication should identify which environmental indicators improve, which may deteriorate, and under what conditions those changes occur. It should explain relevant assumptions, uncertainties, system boundaries and comparison conditions. Where appropriate, results should be presented using several environmental indicators rather than relying exclusively on a single measure such as carbon emissions.

The communication of trade-offs should also avoid creating false precision. If environmental results depend strongly on uncertain assumptions, the uncertainty should be visible to decision-makers. Scenario analysis, ranges, sensitivity analysis and comparative lifecycle results can help communicate this uncertainty.

Environmental communication should also distinguish between environmental impact and environmental benefit. A technology may generate an environmental burden while simultaneously enabling a larger environmental improvement elsewhere in the system. The important question is therefore whether the overall system effect is understood and supported by evidence.

8.26 Chapter Summary

Environmental technology evaluation requires lifecycle thinking.

The relevant question is not simply:

“Is the technology environmentally friendly?”

It is:

“What environmental resources does the technology require, what impacts does it generate throughout its lifecycle, what environmental benefits may it produce, how are these impacts distributed, and how uncertain are the findings?”

This broader question reflects the central argument of environmental technology evaluation. Technology should not be assessed solely according to its visible operational characteristics. Environmental consequences may be distributed across raw-material extraction, manufacturing, transportation, infrastructure development, operation, maintenance, replacement, reuse, recycling and disposal.

Lifecycle thinking is therefore essential because environmental impacts can be transferred from one stage to another. A technology may reduce operational emissions while increasing manufacturing requirements. A system may reduce energy consumption while increasing demand for minerals. A digital service may reduce physical transportation while increasing electricity consumption and data-centre infrastructure requirements. An electric vehicle may eliminate tailpipe emissions while creating environmental burdens associated with battery materials, manufacturing and electricity generation.

The appropriate assessment must therefore consider the complete system.

Life-Cycle Assessment provides an important methodological foundation for this process. It establishes a structured approach for defining the purpose of an assessment, identifying system boundaries, selecting functional units, collecting lifecycle inventory data, assessing environmental impacts and interpreting results.

The functional unit is particularly important because technologies should be compared according to the service or function, they provide rather than simply according to the physical products themselves. Comparing two technologies without establishing equivalent functionality can produce misleading conclusions.

System boundaries are equally important. A narrow assessment may examine only operational energy consumption, while a broader assessment may include raw materials, manufacturing, transportation, infrastructure, use, maintenance and end-of-life management. Comparisons should use compatible boundaries so that environmental advantages are not created simply by excluding relevant stages.

Emerging technologies present additional methodological challenges. New technologies may have limited operational histories, uncertain future efficiencies, changing manufacturing processes, uncertain adoption levels and incomplete information about end-of-life management. Environmental assessment must therefore incorporate appropriate forms of uncertainty management.

Uncertainty does not make environmental evaluation impossible. Instead, it requires greater transparency concerning the quality of evidence and the assumptions used. Sensitivity analysis can identify the parameters that most strongly influence results. Scenario analysis can examine alternative future conditions. Ranges can be used where precise estimates are not justified.

Environmental sustainability also extends beyond carbon emissions. Energy consumption, water use, mineral requirements, land use, biodiversity, pollution, waste generation and ecosystem effects can all be relevant. A technology that performs well on one indicator may perform less favourably on another. Comprehensive evaluation therefore requires multiple environmental dimensions.

Circular-economy principles further expand the analysis. Technology should be evaluated according to whether it can support longer useful lives, repair, refurbishment, upgrading, reuse, remanufacturing and material recovery. Product design can influence environmental performance long before a technology reaches the consumer because design decisions affect material requirements, durability, maintenance and end-of-life possibilities.

Geographical context is also essential. Environmental performance depends partly on where resources are extracted, where manufacturing occurs, what energy sources are available, where the technology operates and how end-of-life materials are managed. The same technology may therefore have different environmental profiles in different countries or regions.

Environmental justice introduces another dimension. Aggregate environmental impacts do not reveal how those impacts are distributed among communities. Resource extraction, manufacturing pollution, waste disposal, water consumption and infrastructure development may affect particular populations more heavily than others. Environmental assessment should therefore consider both total impact and distributional consequences.

Climate resilience complements lifecycle environmental assessment by asking how environmental change may affect technological systems. A technology may have a relatively low environmental footprint while remaining vulnerable to heat, flooding, drought, water scarcity, supply-chain disruption or other climate-related conditions. Sustainable technology evaluation therefore needs to consider both the environmental effects of technology and the effects of environmental change on technology.

Technology and sustainable development must similarly be evaluated through demonstrated causal pathways. The existence of a technology does not automatically establish a contribution to sustainable development. The evaluator should identify how the technology changes behaviour, processes, resource use or outcomes and whether those changes produce measurable environmental, social or economic benefits.

The environmental dimension of technology evaluation should therefore be integrated with the wider dimensions of AMTEF. Technical performance, economic value, social consequences, environmental sustainability, ethical considerations, governance, risk, resilience and long-term sustainability are interconnected.

The central principle is that technological value cannot be determined solely by what a technology can do. It must also consider what resources the technology requires, what consequences it produces, who experiences those consequences, how long those consequences persist, what alternatives exist and how confidently the evidence supports the assessment.

Environmental technology evaluation is consequently not a single measurement exercise. It is a structured process of evidence collection, comparison, interpretation, uncertainty assessment and decision-making.

The objective is not to identify technologies that have no environmental impact, because virtually every physical technology requires resources and creates some form of environmental burden. The objective is to understand the relationship between environmental costs and benefits and to identify conditions under which technology can contribute to more sustainable systems.
