Sixty-six percent. That is where HP Inc. stood on renewable electricity matching as of its 2025 environmental report — well short of the 100 percent target it set a decade ago for 2025, and the reason the company formally pushed its deadline to 2040 in May.

HP attributed the extension to uncertain availability of qualifying power and difficult market conditions in regions where it operates. The company, one of the early corporate signatories inspired by the Climate Group's RE100 campaign, matched 66 percent of global electricity consumption with renewables in its latest disclosure, up from 62 percent a year earlier.

HP's shortfall is not an outlier. RE100's annual disclosure report, published Sept. 18 and covering 408 reporting companies, shows many members citing higher costs, limited supply and unfavorable policy conditions — particularly in South Korea — as obstacles to progress.

"100 percent renewable is a really, really difficult target," said Sam Kimmins, director of energy at Climate Group. "What's great is that most companies are sticking with their values and sticking with their goal, despite those headwinds. Sure, some are pushing them out a little bit. … It shows that they're being upfront about what challenges they are facing."

The aggregate picture

RE100 launched in 2014 and requires members to commit to 100 percent renewable electricity for their operations by 2050. Roughly 440 companies now belong to the initiative, though not all contributed data to the September report.

Collectively, RE100 members cover an average of 59 percent of their electricity with renewables — up from 53 percent in 2024 and, in aggregate volume, enough power to run Spain for a year. Many members report supply constraints in the United States and South Korea, driven largely by policy headwinds.

Attrition remains minimal. Meta is the only company to have exited, leaving in July "by mutual decision" after concluding it could no longer meet some of RE100's technical criteria.

About 70 members now match at least 90 percent of their electricity consumption with renewables. Nike is the newest arrival at the top tier: the company reported Sept. 17 that it had reached its 100 percent renewable electricity milestone.

"At Nike, we focus on the parts of our value chain where we can drive the greatest impact," Nike Chief Sustainability Officer Cimarron Nix said in a statement. "That's why renewable electricity is both an environmental priority and a supply chain opportunity."

Growth shifts to Asia

Corporate membership has grown 60 percent since 2020, with Asia leading the expansion. In South Korea, RE100 members account for roughly 10 percent of national electricity demand — yet only 12 percent of that consumption is covered by renewables, underscoring the supply gap that members repeatedly flag.

"Companies are joining us not just because it's environmentally the right thing to do," Kimmins said. "They want renewables because renewables represent energy security."

RE100's new priority recruitment markets are Indonesia, Mexico, South Africa and Thailand, alongside continued focus on India, Japan, South Korea and Taiwan.

"The bigger the aggregated demand signal, the more change we can create, and we do have a direct line into at the minister level into most of the major economies in Asia," Kimmins said.

The next accounting frontier: hourly matching

Climate Group is also backing an RE100-adjacent effort, the 24/7 Carbon-Free Coalition, launched in June. Member companies are developing programs to match their electricity with "carbon-free energy" — a category that may include nuclear power — on an hourly basis rather than annually.

The regulatory stakes are concrete. Hourly matching requirements have been proposed as part of upcoming revisions to the Greenhouse Gas Protocol's Scope 2 accounting rules for purchased electricity. Feedback on a draft circulated earlier this year, however, showed limited support for the idea.

The coalition's eight launch members include AstraZeneca, Google and Unilever, which have pledged to publish details on their approaches — what works and what does not. The group is not designed for mass participation yet.

"We see the coalition as the pioneers who are testing this out," Kimmins said.

What to watch

Two milestones will determine the trajectory. First, the final Scope 2 revision from the Greenhouse Gas Protocol: if hourly matching becomes part of the standard, corporate procurement contracts and renewable energy certificate markets will have to reprice around time-stamped supply. Second, RE100's 2026 disclosure report will show whether the 59 percent average continues to climb and whether more members follow HP in pushing deadlines — or follow Nike across the finish line.
