As the race to meet ambitious sustainability targets heats up, fashion is directing more attention to decarbonization, hoping to cut supply chain emissions at the source. But delivering impact isn’t as easy as it might seem. Between fashion’s penchant for fragmented, global supply chains and its tendency towards top-down sustainability strategies that overlook the role of suppliers in scaling decarbonization, progress has been slow.
In recent months, a slew of decarbonization-adjacent reports have been published, offering fresh perspectives on one of fashion’s most critical challenges.
But trudging through multiple 30-plus-page reports isn’t for the faint-hearted, so Vogue Business decided to do the heavy lifting. Below, you will find the key takeaways from six recent reports, charting the findings that challenge assumptions, the data that backs up commonly held beliefs, and the facets of decarbonization previously overlooked.
Several of the reports repeat similar messages: decarbonization is moving too slowly, for example, or that brands are not doing enough to help suppliers accelerate action. Taken as a whole, the reports offer a “surround sound” effect, which can help bring credibility and awareness to the efforts of smaller nonprofits and labor groups by reinforcing their messaging, says Ruth MacGilp, a climate campaigner at Action Speaks Louder. “This way, it’s not just an activist screaming outside a brand’s office, it’s a whole ecosystem sharing the same message, albeit with different accents.”
The relevance of recent decarbonization reports to broader sustainability topics is “refreshing”, says MacGilp. “A few reports have come out recently which link climate change with labor rights and business resilience — not looking at them as siloed issues, but encouraging brands to take an integrated approach that addresses the root causes. We know that when you only address one issue at a time, you get unintended consequences, so the more we can make those links, the better.”
The reality check
In January, member-led nonprofit Cascale released its 2026 State of the Industry report, offering a sobering reality check for fashion’s decarbonization efforts. The report aggregates data from 13,000 Tier 1 and Tier 2 facilities, which submitted self-assessments to Cascale’s Higg Facility Environmental Module (FEM) tool for independent auditing and verification.
One solution many brands are pinning their hopes on is electrification, shifting from fossil fuels to renewable energy-powered electricity. Electrification alone will be “insufficient” to meet the Paris Agreement, Cascale reports, largely because production countries are generally lacking in grid-level renewable energy. This means on-site renewable energy infrastructure (such as solar panels) and off-site energy sources (such as wind farms) will be “critical”. Right now, renewable energy accounts for just 2% of the industry’s total energy use. But this shouldn’t be an excuse for brands to abandon particular production countries or suppliers, says Joël Mertens, director of Higg Product Tools. Instead, brands should use the report to motivate deeper supplier engagement, long-term partnerships that include co-investing in decarbonization, and moving beyond the “low-hanging fruit” to pursue “deeper transformation”.
