Essential oils are widely appreciated for their natural origin and aromatic qualities—but “natural” does not always mean sustainable. Like all raw materials, essential oils come with environmental considerations that brands and product developers should be aware of. This overview outlines key factors to help you make informed sourcing and formulation decisions.
Why Essential Oils Can Carry Environmental Challenges
Essential oils require large volumes of plant material, specialized extraction processes, and global transport. Depending on species, geography, and farming practices, the environmental impact can vary significantly. Below are the primary factors sustainability teams and formulators evaluate.
1. Overharvesting and Pressure on Natural Populations
Many high-demand essential oils rely on wild harvesting—from forests, grasslands, or remote regions. Without strict management, this can lead to:
- Overexploitation of slow-growing or vulnerable plant species
- Disruption of local ecosystems
- Reduced biodiversity
- Long-term supply instability
Even cultivated crops can face strain when demand outpaces sustainable growth cycles.
2. Habitat Disruption and Land Use Concerns
Some essential oils require large areas of land to grow the necessary biomass. This can contribute to:
- Clearing natural habitats for cultivation or expanded farming
- Pressure on forested or biodiverse regions
- Soil degradation when cultivation replaces ecological vegetation
Even well-managed farms must carefully balance yield with long-term ecological health.
3. Extraction, Processing, and Pollution
While many essential oils are extracted through steam distillation, some require solvents or more intensive processes. Environmental impact can arise from:
- Solvent use and improper waste disposal
- Water consumption during extraction
- Energy requirements for heating and distillation
- Use of fertilizers or pesticides in cultivation
4. Farming Practices and Resource Intensity
To meet global demand, some essential-oil crops are grown in monocultures or require significant agricultural resources. Depending on the crop, this may involve:
- High water usage
- Frequent soil turnover or erosion
- Lower long-term soil fertility
- Reliance on synthetic inputs for yield stability
5. Carbon Footprint Across the Supply Chain
Essential oils are globally traded commodities. Their lifecycle footprint often includes:
- Energy-intensive extraction (particularly steam distillation)
- Long-distance transport from origin regions to buyers worldwide
- Cold-chain or specialized storage requirements for select materials
While essential oils can be beautiful and effective materials, their environmental impact varies widely depending on the crop, manufacturer, supply chain, and sourcing philosophy.
Choosing More Sustainable Fragrance Options
Natural and plant-based fragrance materials can absolutely be used responsibly—it depends on sourcing, transparency, and formulation strategy. Many brands also choose blends of natural and nature-identical materials to reduce agricultural pressure while achieving consistent aromatic quality.

Frequently Asked Questions
Are essential oils bad for the environment?
Not inherently. The impact depends on species, farming practices, extraction methods, and sourcing transparency. Some essential oils are sustainably produced; others face ecological pressures.
Is it more sustainable to use synthetic fragrance materials?
Sometimes. Nature-identical materials can reduce pressure on endangered botanicals, offer consistency, and support lower-impact supply chains. Many sustainable fragrances use blends of natural and safe-synthetic materials.
Are plant-based ISO 9235 materials always environmental-friendly?
ISO 9235 defines “natural,” not “sustainable.” Sustainability depends on agricultural and supply chain practices. Both natural and synthetic materials can be produced responsibly.
How can my brand make more sustainable fragrance decisions?
Choose transparent suppliers, review documentation, understand agricultural impacts, and consider using concentrated oils to reduce usage and footprint.
In Summary
Essential oils are beautiful materials, but their environmental impact depends on how they are grown, harvested, processed, and transported. With mindful sourcing and responsible formulation, brands can enjoy these materials while minimizing ecological impact.
