Candles aren’t going anywhere. But the way people shop for them — and what they expect from them — is shifting fast.
Welcome to the sustainable candles trend. In 2025, more consumers are saying no to single-use, toxin-filled candles and yes to options that align with their values. Think natural ingredients, reusable vessels, and transparency about what’s inside. If you're a brand, retailer, or curious shopper, here's what to know.
Market Momentum: The Candle Category Is Growing — and Sustainability Is Leading the Charge
The global candle market is projected to grow from roughly $15.3 billion in 2024 to nearly $26 billion by 2034. That’s a steady clip — but here’s what’s more interesting: the eco-friendly candle segment is growing even faster, with some estimates forecasting an 8%+ compound annual growth rate (CAGR) into the next decade.
So what’s driving it?
Consumers are paying more attention to how products are made, packaged, and disposed of. That includes candles. The expectation isn’t just “smells good” — it’s “clean ingredients, zero waste packaging, and maybe something I can reuse.”
What’s Powering the Sustainable Candles Trend
1. A Shift in Values: Eco-Conscious, Health-Focused, Design-Driven
People care more than ever about what’s in the air they breathe. That means clean-burning waxes (like soy, coconut, or beeswax), non-toxic fragrance oils, and cotton wicks are becoming non-negotiables. At the same time, home goods need to look as good as they function — especially for the millennial and Gen Z audiences who are styling their homes with intention.
2. Refill Culture and Zero Waste Formats
Single-use is out. Just like people bring reusable bottles and bags, they’re seeking refillable candles that don’t create unnecessary waste. Systems that allow the same candle vessel to be used again and again, like our refillable candle, are becoming not just viable, but expected. And if you’re exploring refillable options yourself, our guide to the best refillable candles explains what actually makes a refill system safe, clean, and truly sustainable.
And it’s not just about less waste — it’s about a better experience. Our zero waste candle refills pop in and out cleanly with no scraping or reheating needed.
3. Candles as Self-Care and Aesthetic Objects
Candles are no longer just functional — they’re ritual. A wind-down moment at night. A Sunday cleaning vibe. A thoughtful gift. As they take on more meaning, people are willing to invest in options that align with their mood and values.
4. Rise of DTC and Niche Brands
Direct-to-consumer (DTC) brands have leveled the playing field. Shoppers now seek niche, mission-driven companies they feel aligned with — and sustainable candle brands are riding that wave. People don’t just want to buy a candle. They want to buy into a story.
So What Actually Is a Sustainable Candle?
It’s a fair question. “Sustainability” gets thrown around a lot — but here’s what it actually means in the context of candles:
- Plant-based wax (like soy or coconut), not paraffin
- Non-toxic fragrance oils — safe for people, pets, and planet
- Cotton wicks for a clean, even burn
- Reusable or refillable vessels, like our handmade ceramic vessel
- Minimal or recyclable packaging
- Transparent sourcing and ethical production practices
Refillable and zero-waste formats are becoming a key part of this definition — not just as a bonus, but as a baseline.
What’s Emerging in 2025 (and What to Watch Next)
Sustainability isn’t static. Here are a few trends within the trend that we’re seeing take shape:
- Refillable systems: More brands are developing plug-and-play refills to reduce waste.
- Subscription models: Our candle subscription box is one example — delivering zero waste refills right to your door, on your schedule.
- Scents with benefits: Think lavender for sleep, eucalyptus for clarity — wellness is becoming a core candle feature.
- Premium meets purpose: People are willing to spend more for design-forward, sustainable products that feel special.
- Global expansion: Demand is rising in Asia-Pacific and Latin America as urban consumers look for cleaner, better options.
The Opportunity (and Challenge) for Candle Brands
Sustainability opens up a world of opportunity — but it’s not without its challenges.
The hard stuff:
- Higher costs for clean wax, ethical sourcing, and better packaging
- Supply chain volatility — especially with natural materials
- Consumer education — not everyone understands the difference between a greenwashed label and a truly sustainable product
The upside:
- Loyalty and retention — refillable systems naturally encourage repeat purchases
- Stronger positioning — clean design + clean ingredients = brand love
- PR and storytelling potential — people love a product with a purpose
- Higher perceived value — especially for gifting and home design
