Cambodia's garment sector is at a delicate crossroads. With nearly one million direct jobs and over 70% of total exports, this Southeast Asian textile hub's every move affects global fast-fashion and sportswear supply chains. However, the variable that will truly determine its future position has shifted from labor cost to the share of green electricity in its energy mix.
Brand sourcing logic is being rewritten
Global apparel brands have fundamentally changed their supplier evaluation criteria. Delivery time, price, and labor compliance were once the core metrics. Now, carbon emission data carries equal weight to price. Several European and North American brands have publicly committed to achieving carbon neutrality in their supply chains by 2030, meaning their sourcing teams will prioritize factories with higher proportions of renewable energy.
For Cambodia, this is an urgent signal. Its current electricity mix is still dominated by hydropower and coal, with solar and wind accounting for less than 15% of grid capacity. If the country cannot raise the green electricity share to above 30% within two years, its garment exports may face implicit downgrades or even order losses from some brands.
Energy sensitivity of nearly one million jobs
Cambodia's garment industry employs nearly one million workers, mainly in industrial parks in Phnom Penh, Sihanoukville, and Takeo province. Electricity costs account for 8% to 12% of total production costs, significantly higher than peers in Bangladesh or Vietnam. When global brands begin requiring suppliers to disclose Scope 2 (purchased electricity) emissions, factories using high-carbon power will automatically enter brands' risk monitoring lists.
More critically, this pressure comes not from government regulation but from commercial contracts. Once low-carbon clauses are written into procurement framework agreements, factories that fail to meet standards face direct consequences such as order cancellations or reduced purchase volumes. This is far more immediate and effective than any carbon tariff.
Industrial chain transmission: from power plant to sewing machine
The impact of renewable energy on competitiveness is not linear. First, the levelized cost of solar and wind power has dropped about 40% over the past five years, now lower than that of new coal-fired projects in Cambodia. This means that concentrated rooftop solar deployment or signing green Power Purchase Agreements (PPAs) in industrial parks can not only score points on carbon accounting but also reduce electricity expenses.
Second, brand-side pressure is propagating upstream along the supply chain. Fabric processing and dyeing are far more energy-intensive than garment sewing. Factories in Cambodia that also have dyeing and finishing capabilities face a more urgent need for energy transition. Industry public data shows that a medium-sized dyeing plant using 100% green electricity could reduce about 12,000 tons of CO2 annually, contributing roughly 30% of a brand's emission reduction target.
Variables in Southeast Asia's competitive landscape
Cambodia is not competing in a vacuum. Vietnam's textile industrial parks have already installed rooftop solar on a large scale, while Bangladesh is pushing for a transition from natural gas to renewable energy. If Cambodia can deploy green electricity faster than its neighbors, it has a chance to become brands' 'priority low-carbon sourcing destination.' Otherwise, it risks being edged out of procurement shortlists.
Currently, the Cambodian government has set a renewable energy target, aiming to increase non-hydro renewable installed capacity to 35% of total capacity by 2030. However, at the implementation level, grid absorption capacity, foreign investment policy stability, and industrial park infrastructure remain obstacles to overcome.
