World Benchmarking Alliance reveals corporate potential and gaps in climate action among top global firms

The World Benchmarking Alliance’s assessment of the planet’s 2,000 most influential firms paints a study in both promise and shortfall: collectively these corporations could “unlock” a substantial portion of the financing needed for the net zero transition, but many remain unwilling or unable to move at the pace required.

According to the Environment Journal’s summary of the WBA analysis, redirecting capital within these companies could generate about $1.3 trillion , roughly 30% of the net zero investment the report says is needed this year , if they committed a greater share of spending to climate-aligned activities. The most commonly reported climate investments included electrified transport, green ammonia and fertilisers, battery production, regenerative agriculture, renewable energy and low-impact construction.

The scale and influence of the cohort are stark but reported totals vary across WBA material: the lead article cites combined revenues of $48 trillion and responsibility for 54% of global emissions, while other WBA releases describe the SDG2000 as representing between $43 trillion and $45 trillion of revenue and roughly 42–50% of global GDP. Those differences reflect alternative accounting frames used across WBA publications; whichever figure is used, the point is the same , a relatively small group of firms hold outsized leverage over emissions and system change.

The WBA’s SDG2000 list spans companies headquartered in 86 economies and, the organisation says, represents the businesses with greatest leverage across seven transformation areas including Decarbonisation and Energy, Food Systems and Circular economy approaches. The Alliance launched its corporate sustainability benchmark in January 2026, setting out to rank and assess these firms across multiple metrics to drive corporate accountability.

Despite the potential for mobilisation, WBA’s research finds troubling gaps in ambition and measurement. The Environment Journal coverage noted only 23% of the 2,000 firms reported carbon-reducing investments at a median of more than 7% of capital expenditure. Separately, WBA has warned that less than a third of the SDG2000 have submitted greenhouse gas reduction targets to the Science Based Targets initiative (SBTi), a signal that many pledges lack third-party alignment.

Nature and biodiversity assessments were found to be especially weak among the highest-impact industries. For the 750 largest firms in sectors such as food, mining and paper, just 14% measured their dependence on ecosystem services and 34% provided evidence of managing nature-related risks through biodiversity assessments, water re-use, resilient infrastructure or regenerative agriculture. Only 9% could quantify how those threats would affect their business, finances or reputation, and merely 4% were assessing how healthier ecosystems could present opportunities for growth.

WBA’s executive director emphasised the contrast between progress and inertia. “Our research shows a striking diversity in performance: while some companies are making impressive progress, too many continue to fall behind. In the midst of rising climate impacts, geopolitical tensions and economic uncertainty, companies still have a choice in how they respond,” Gerbrand Haverkamp said, adding that “progress is possible, and a growing group of companies are proving that meaningful action can be taken today,” while warning that some firms are “backsliding or stagnating.”

Industry data in WBA’s materials underline the leverage argument: the SDG2000 employ tens of millions directly and are embedded in global supply chains that extend influence to hundreds of millions more. WBA argues that if leading firms shifted investment away from environmentally damaging activities , for example, new combustion-vehicle production , they could set a precedent that encourages wider corporate reallocation of capital.

The research therefore frames a clear policy and investor implication: companies should be held to account not only for commitments but for measurable emissions reductions and climate-directed investments. WBA urges policymakers, investors, NGOs and consumers to press these firms to submit credible targets, scale up capital for proven solutions and close critical blind spots on nature-related risks.

If the SDG2000 can be nudged from rhetorical commitments to sustained capital reallocation, WBA suggests the private sector could unlock material finance for the transition. But the organisation’s evidence also makes plain how far many firms remain from the science-based pathways necessary to keep 1.5C-aligned decarbonisation within reach.
