Linear sustainability

Linear sustainability is an environmental management approach that seeks to reduce the negative impact of traditional production systems, based on the linear 'take, make, dispose' model, without altering their fundamental structure. In other words, it tries to make more efficient a model that still depends on intensive resource extraction, high consumption and the systematic generation of waste.

Although it promotes improvements such as energy efficiency, emissions reduction and the responsible use of inputs, linear sustainability does not question unlimited economic growth or the extractive logic of the system. It is therefore best seen as an initial transition towards more regenerative models, useful but insufficient to respect planetary boundaries over the long term.

Linear versus circular sustainability

The sustainable linear model focuses on 'doing less harm': producing with less water, emitting less CO₂, using less energy. By contrast, the circular economy proposes a structural change: eliminating the very concept of waste, keeping materials in use and regenerating natural systems.

Concrete examples of linear sustainability

• Buildings with better thermal insulation, but built with non-recyclable materials.
• More efficient vehicles, but still based on mass individual mobility.
• Reduced plastic packaging, without rethinking the 'use and throw away' logic.
• Crop production with fewer fertilisers, but within the same intensive, extractive model.

These practices lower the ecological footprint, but they do not halt environmental degradation or reverse biodiversity loss and resource depletion.

Why does this model persist?

Linear sustainability is attractive to many sectors because:

• It is more compatible with current business models.
• It allows gradual progress without redesigning processes.
• It offers economic returns in the short term.
• It fits easily into existing certifications and ESG reporting.

In conservative corporate or institutional settings, it is seen as a pragmatic way to meet regulation without changing the core of the system.

Criticisms of the sustainable linear model

Many experts warn about the structural limits of this approach:

• It does not address the root causes of ecological breakdown, such as overconsumption or unequal access to resources.
• It can create a false sense of progress, where small efficiency gains mask unsustainable practices.
• It can be used as a greenwashing tool, presenting as 'sustainable' processes that remain destructive.
• It can divert public and private investment away from transformative solutions towards marginal improvements.

Relationship with climate change mitigation

Linear sustainability can contribute to climate change mitigation, especially in sectors such as energy, transport and industry. However, its results are limited:

• Cutting a plant's emissions by 20% does not resolve installed overcapacity.
• Improving the efficiency of intensive agriculture does not reverse soil degradation.

In a climate emergency, incremental reduction is not enough. A systemic approach is needed that tackles both demand and supply, and that prioritises regeneration over mere mitigation.

Can it be a transition stage?

Yes. In many cases linear sustainability represents a first phase in the evolution towards more circular, regenerative or distributive models. It improves processes, changes habits and raises awareness.

However, it is essential that it does not become an end in itself, but is integrated into a more ambitious, transformative vision. Otherwise it can perpetuate unsustainability behind technocratic or superficially green language.

Cases that have moved beyond linear sustainability

Some organisations have evolved towards post-linear models. Examples include:

• Fashion companies moving from fast fashion towards regenerative design and garment rental.
• Cities replacing incinerators with separate collection, composting and reuse systems.
• Farmers abandoning intensive monoculture for agroecology.

These cases do not aim only to 'do less harm', but to generate positive impacts for communities, ecosystems and local economies.

Beyond linear sustainability

Linear sustainability was necessary to introduce efficiency and responsibility into a historically destructive system. But today, faced with the climate crisis, biodiversity loss and structural inequality, its limits are clear. The future calls for a transition towards models that not only reduce impacts but regenerate, redistribute and reimagine how we produce, consume and live: linear sustainability is a starting point, not a destination.
