- Limited supply of renewables named the top barrier in markets around the world, particularly South Korea, Singapore, and Japan
- Governments “serious about shielding their economies from the devastating effects of fossil fuel instability” need to act now, Climate Group says
- Despite challenges, global sports brand Nike, Inc. reaches 100% renewable energy globally, demonstrating what sustained action can achieve
New York/London, September 18, 2026 – Global businesses are making progress towards 100% renewable electricity, but many say policy, market and procurement barriers are still slowing adoption and limiting access to the renewable energy they need.
Leading companies switching to 100% renewables are citing “limited supply and cost” as the biggest barrier in key markets, followed by a “lack of procurement options” and “regulatory barriers”.
The latest RE100 Annual Disclosure Report, published ahead of Climate Week NYC, shows how companies are being denied the benefits of secure, home-grown renewable energy to shield themselves against price hikes amid the energy crisis. In New York City, business and government leaders will discuss how to tackle barriers and speed up progress.
South Korea is the market where the largest number of RE100 companies say they’re facing procurement barriers, followed by other Asian markets, including Singapore and Japan. While barriers exist in China, ranked 6th, and India, ranked 8th, these two markets also have a relatively large proportion of RE100 members that have achieved 100% renewables (28% in both markets), indicating that leading businesses are finding ways to work around such hurdles.
More than 70 RE100 members have achieved between 90% and 100% renewable electricity use. Companies verified at 100% recently include Asahi, Aviva, K-water, Lloyds, and Mitie.
At Climate Week NYC, Nike, the global sports brand, will share their latest progress, including how it has met its RE100 target this year, covering 100% of its worldwide energy needs with renewables for the first time. The milestone builds on decades of action and provides a strong foundation for Nike’s continued work across its value chain. That includes deepening collaboration with suppliers and industry partners to expand renewable-energy access, strengthen capabilities and scale solutions beyond Nike.
Cimarron Nix, Chief Sustainability Officer, Nike, says: “At Nike, we focus on the parts of our value chain where we can drive the greatest impact. That's why renewable electricity is both an environmental priority and a supply chain opportunity. Through collaboration with suppliers and organizations such as RE100, we're helping expand access to renewable energy, share what we've learned and create pathways that can accelerate progress beyond our own business. The transition to renewable electricity requires pre-competitive collaboration, and we're proud to contribute alongside others working to build a more resilient energy future.”
Helen Clarkson, CEO, Climate Group, says: “The world’s leading companies are hungry for renewables, and their investments are shaping a smarter new energy future for all. But grid bottlenecks, regulatory constraints, and market inefficiencies are restricting what they can buy. Governments serious about shielding their economies from the devastating effects of fossil fuel instability need to urgently break down these barriers.”
The RE100 Annual Report, gathering data from more than 400 companies, is the most detailed annual dataset on voluntary corporate renewables procurement globally.
Further key findings include:
- Companies are advancing at pace towards 100% renewables in several key markets, with major increases in members’ use in South Africa (from 54% to 84%) and Mexico (from 38% to 52%).
- Increases are smaller across challenging Asian markets such as Indonesia (33% -> 35%) or Japan (36% -> 40%).
- In markets where the highest number of RE100 companies cite barriers, procurement is lagging most:
- In South Korea, renewables account for just 12% of members’ energy use. This is unchanged from last year. The share of companies procuring 100% is just 5%.
- In Taiwan, RE100 companies met 6% of their energy needs with renewables. Only 9% of members procure 100% renewables.
- In Singapore, renewables make up 6% of members’ use – up 1% from last year.
Sherry Madera, CEO, CDP: “The data is clear: corporate demand for renewable electricity is growing, but access is not keeping pace. In too many markets, limited supply, infrastructure constraints and a lack of procurement options are preventing companies from translating their ambition into action. Addressing these barriers can unlock greater private investment in renewable energy, accelerate the development of clean power systems and enable more companies to deliver on their climate targets.”
Collectively, RE100 companies now run on 59% renewable electricity globally, enough to power Spain for a year. They purchase 65% of this from facilities set up within the past 15 years, underlining how companies are adding brand-new, additional renewables capacity to grids.
