Recently shuttered coal mines around the world can have new life as solar farms, potentially adding nearly 300 gigawatts (GW) of clean energy by 2030, a first-of-its-kind analysis by researchers from Global Energy Monitor (GEM) has found.

GEM’s Bright side of the mine report identified 312 surface coal mines that had been closed since 2020, as well as 134 that were likely to close by 2030. Together, these wastelands cover 2,250 square miles, reported The Guardian.

“Coal was once billed as the ‘buried sunshine’ of a prehistoric past. But the world has now entered an age of solar energy — a time when harnessing the sun has become more accessible, affordable, and environmentally sustainable than digging it up in fossil fuels,” a press release from GEM said.

Our new analysis finds that converting 446 coal mines could add nearly 300 GW of solar — equal to 15% of global capacity.

Most of this potential is concentrated in a few regions, highlighting where targeted action could deliver outsized clean energy gains.

The world installed a record nearly 600 GW of solar capacity last year, and over 2,000 GW of utility-scale solar projects are currently in development. But these projects require widespread land use, and developers often find it hard to find prime locations that are not off limits or already being used. But there are vast tracts of scarred land across the globe in the form of abandoned coal mines that can be repurposed.

Since 2020, GEM has conducted a global survey of shut-down surface coal mines and those with planned closures by the end of the decade. The first-time analysis showed that more than 300 of these mines could house roughly 103 GW of photovoltaic (PV) solar capacity, while large operations that are scheduled to close could host another 185 GW across 127 sites.

Because they are already cleared and grid-adjacent, these abandoned mines are prime locations for renewables.

“If these potential solar projects came to fruition, the world could build almost 300 GW of solar capacity on mined out lands by the end of 2030. Uptake on that scale is equal to 15% of the solar that has already been built globally and would add enough solar capacity to inch the world one step closer to tripling renewables before the end of the decade,” GEM said.

Some of the transitional projects have already begun. New data from GEM on coal-to-solar projects shows that there are 90 operational conversions with 14 GW of capacity in China, and 46 additional projects with nine GW of capacity currently in the planning stages.

“The coal-to-solar transition offers a rare chance to repair the environmental hazards and eyesores of open pits,” GEM said. “Constructing solar on upheaved lands isn’t just land reclamation — it’s a chance to align land restoration, clean energy goals, and local job creation.”

Strip mining has turned former wildlife habitats into polluted wastelands stripped of their topsoil. But if the sites were converted to house solar energy plants, they would be able to help the planet by generating enough renewable energy to power a country the size of Germany, the report said.

“The legacy of coal is written into the land, but that legacy does not have to define the future. The coalmine to solar transition is underway, and this potential is ready to be unlocked in major coal producers like Australia, the U.S., Indonesia and India,” said Cheng Cheng Wu, project manager for GEM’s energy transition tracker, as The Guardian reported. “Repurposing mines for solar development offers a rare chance to bring together land restoration, local job creation, and clean energy deployment in a single strategy. With the right choices, the same ground that powered the industrial era can help power the climate solutions we now urgently need.”

8 Best Ethical & Sustainable Flats That Are Effortlessly Chic

Published

on

Ballet flats have long been a staple in my wardrobe, but in the past few years have experienced a significant resurgence — and for good reason. The right pair can be practical, versatile, and oh so chic through days at work, with family, or out for the evening. But finding that “just right” set that’s well-crafted and sustainably made can be a whole other story. That’s why this sustainable flats guide exists.

Comfort, style, sustainability, and longevity are a lot to ask in a shoe, but I don’t believe it’s too much. It just takes some extra digging. And thankfully, I’ve done that digging for you. Because I get it! I want a flat that looks beautiful. I want a flat that’s made responsibly in line with my values. I want a shoe I can actually wear for my life. And I want that shoe to be worth the investment — it has to last. That’s why I vetted through dozens of brands to create this curated list of flats.

What Makes a Flat More Sustainable?

Material Sourcing

Footwear is a tricky category when it comes to sustainable fashion because we ask a lot of our shoes. We wear them in rain or sunshine, paved paths and cobblestone, day in and day out for years. And through it all, they have to remain beautiful. Because when they’re unwearable, there’s not much left to do with them: there is no viable footwear recycling today. Anywhere that calls it “shoe recycling” is really repurposing that footwear. But once it can no longer be worn, it’s simply trash.

In other words, our shoes need to be incredibly durable, even though the most durable materials don’t always come with the lightest footprint. In footwear, when we talk about durability, we usually rely on leather or high-performance synthetic materials. Leather can hold up with many years of wear, getting more beautiful with wear, and is easy to repair when needed. Synthetic materials are also durable, particularly for withstanding the elements like snow and rain.

But sourcing these materials conventionally is highly polluting — so how can we source these materials better?

For synthetics, we have recycled options. Today, that’s largely recycling from plastic bottles, which isn’t without it’s controversies, but there is much innovation happening in the industry around true textile-to-textile recycling.

For leather, I look for:

  • Vegetable-tanned (rather than chromium tanned)
  • Locally-sourced leather (more traceability), and/or
  • Leather Working Group certified leather, which covers responsible management of water, energy, and waste; safe chemical management, traceability of the raw material, and occupational safety for workers.

Notably, there is no certification for animal welfare, so these are imperfect systems. But the alternative is footwear made from synthetic plastic materials or vegan leather alternatives that don’t yet meet the same durability standards as leather. Sustainability within today’s constraints requires trade-offs.

That said, there is always secondhand leather — by buying shoes secondhand you can access the quality of leather without adding further demand for the material.

Responsible Manufacturing

When considering responsible production practices, I look for first and foremost: transparency. Seeing what the brand shares about their material sourcing, their process, and who made their shoes where. And then I look at the details of that process: were the shoes made locally or within a geographic region? How are the workers paid and treated — and under which conditions do they work?

And, sometimes a brand employs an out-of-the-box approach to manufacturing entirely. There are a few slow fashion footwear brands challenging the traditional fashion system of ordering in mass quantities before demand is assessed —which inevitably leads to overproduction. These brands use an “on demand” model instead, producing their shoes only after they’ve been ordered. This reduces the risk of overproduction (i.e. producing more than what gets sold) while also encouraging more thoughtful consumption. You can’t impulse buy a pair of Mary Janes that you have to wait 8 weeks for.

Wearable and Beautiful

The most perfectly environmentally sustainable flat in the world is useless if no one wants to wear it. And as I mentioned earlier, footwear cannot be recycled into new footwear at the end of its life, so we want our shoes to last a really long time. That means they need to be design forward and comfortable, too.

My Top Picks for More Sustainable and Ethical Flats

Keeping all of that in mind, these more sustainable flats brands meet this criteria, albeit to various extents. Some err more on comfort while some more on style. Some have admirable levels of transparency and social impact, while other brands have more of a focus on their ecological impact. I’ve included descriptions alongside each brand as well as a summary of conscious qualities so you can find a brand that meets your priorities best. And, of course, a price range so you know what makes sense for your budget as well.

Some that this guide includes affiliate links which means we may earn a commission if you shop through these links. As always, brands featured in shopping guides are brands that meet our strict sustainability criteria that we think you’ll love.

1. ALOHAS

Spanish brand ALOHAS flips the typical fashion production system on its head with its on-demand model.

Instead of overproducing thousands of shoes to later discount them, ALOHAS does the exact opposite. Its newest styles are available for pre-order at a discount of 30%, so the footwear brand can more accurately forecast demand. Then the shoes — like their flats — are primarily made by local artisans in Spain and Portugal. The brand regularly shows the behind the scenes of their production on their social media.

Conscious Qualities: On-Demand Production, Locally Made

Size Range: EU 35-42 (US 5-11)
Price Range: $195-$225

sustainable black ballet flats

2. Rothy’s

If you’re looking for flats for all-day wear at work or running errands, Rothy’s is my recommendation with their cushy insoles. The brand makes their more sustainable flats from recycled plastic bottles, as well as materials like hemp and merino wool, but they still look sleek enough for the office.

While I might not wear Rothy’s flats to a fashion event (I prefer smooth leather for more elevated occasions), they are more than stylish enough to wear to most of my real-life scenarios. My favorite part about Rothy’s, though, is that they are machine washable.

Materials: Recycled & Natural Materials, Owns One Factory (undisclosed percentage of production)

Size Range: US 5-13
Price Range: $99-$165

3. Vivaia

Vivaia has the most adorable sustainable Mary Janes made from recycled plastic bottles. The adjustable straps and arch support make Vivaia’s Mary Janes suitable for all-day comfort, even if your feet are typically prone to slipping out of flats.

This vegan footwear brand also makes square-toe and pointed-toe flats for a more elevated look. And of the several recycled plastic bottle footwear brands on the market today, Vivaia tends to have the most elevated designs in my opinion.

Conscious Qualities: Vegan, Recycled Materials

Size Range: US 5-11
Price: $97 – $116

4. The RealReal

The RealReal is an authenticated luxury resale platform with contemporary, designer, and high-end luxury brands. Depending on your priorities you can find shoes in anywhere from pristine condition (but higher priced)) to “fair” or even “as is” for the largest discount from full price.

You don’t always have as many options aesthetically when shopping more sustainably, so I like to go to The RealReal when I’m looking for specific styles. I was recently looking for Mary Janes with feminine detailing and came across Larroude Flats on The RealReal, where I purchased a pair of neutral scalloped accent flats. (Pictured here!)

Conscious Qualities: Secondhand

Size Range: US 3.5-14
Price Range: $9+

5. ESSĒN

ESSĒN elegant, minimalist footwear is artisan handcrafted from Leather Working Group-certified leather in solar-powered facilities in Italy, Portugal, and Spain. Each shoe also comes with a product passport where you can view the step-by-step journey that product took through the brand’s supply chain from raw material to manufacturing to packaging and distribution.

Beyond transparency and responsible manufacturing, ESSĒN’s slow fashion business model prevents overproduction by operating on a made to order basis. Meaning while sizes and styles are predefined, the shoes are only produced after they’ve been ordered.

Conscious Qualities: LWG Certified, Supply Chain Transparency, On Demand Production

Size Range: EU 35-44 (US 4-13)
Price Range: $295-$450

Chocolate brown leather classic flats

6. Allbirds

Another comfort-first footwear option besides Rothy’s is Allbirds. The brand creates lightweight, super smooth and breathable flats from tree fibers, aptly called “Tree Breezers”. The (washable) shoes are also soft enough to wear without socks.

The Allbirds Tree Breezers are far more comfortable than typical flats, though I find that the Rothy’s are slightly comfier.

Conscious Qualities: Natural materials (FSC-Certified eucalyptus, castor mean oil, sugarcane EVA)

Size Range: US 5-11
Price Range: $105-$125

Gray wool flats

7. Darzah

Fair trade certified by Fair Trade Federation, Darzah’s ethical flats are entirely hand-embroidered and handcrafted in Palestine from locally sourced leather.

The tatreez flats from this nonprofit are embroidered by refugee and low-income women artisans in the West Bank with this traditional Palestinian techniques.

Conscious Qualities: Sustains Heritage Crafts, Fair Trade Certified

Size Range: EU 36-41 (US 6-10)
Price Range: $199 – $209

8. Nisolo

If you’re seeking a quality pair of classic leather flats ideal for your capsule wardrobe, Nisolo is a strong pick. Nisolo’s flats are handcrafted by artisans using leather sourced from a Leather Working Group certified tannery.

I’ve been wearing my Nisolo shoes for many years and can attest to their quality and durability.

That said, the brand has recently turned over to new ownership and now has significantly less information about their sustainability and ethics in their supply chain. I will be keeping a close eye on this brand to see if it continues to uphold the values Nisolo has long held.

Conscious Qualities: LWG-Certified, Artisan Handcrafted

Size Range: US 5-11
Price: $138 – $198
