• More than 700 Climate Pledge signatories across 49 countries and territories now represent $3.8 trillion in combined annual revenue.
• Signatories reduced reported operational carbon emissions by an average 11%, compared with a 7% reduction among companies outside the Pledge.
• Purchased energy emissions fell 35% on average, but direct operational emissions declined just 4%, highlighting persistent challenges in transport and industrial processes.

Seven years after The Climate Pledge launched, its corporate membership is expanding while reported emissions data points to faster decarbonization among participating companies than their industry peers.

The 2026 Climate Pledge Report covers more than 700 signatories spanning 62 industries and 49 countries and territories. Together, those businesses generate $3.8 trillion in annual revenue, giving the initiative significant purchasing power across energy, transport, construction and industrial supply chains.

The report, prepared by Amazon in collaboration with Global Optimism and participating signatories, found that members collectively reduced reported operational carbon emissions by an average 11%. Companies outside the Pledge recorded an average reduction of 7% over the same period.

Corporate climate commitments continue to expand

The Climate Pledge was founded in 2019 with a commitment to reach net-zero carbon emissions by 2040, a decade ahead of the Paris Agreement’s 2050 timeline.

Membership continued to grow in 2025 despite broader pressure on corporate climate strategies. Another 107 companies joined during the year, increasing the number of signatories by 19% from 2024.

Growth also broadened the initiative’s sector and geographic reach. The Pledge added 51 fashion and beauty brands, bringing that sector’s total to 60. Signatory numbers in Latin America rose 164% between 2024 and 2025, while Asia Pacific membership increased 24%.

The scale matters for sectors where individual companies have limited ability to transform infrastructure alone. Aggregating corporate demand can help suppliers justify investment in emerging technologies while giving buyers greater access to lower-carbon alternatives.

Emissions fall faster among signatories

The report found that signatories collectively cut 14 million metric tons of carbon dioxide equivalent from direct operations and purchased energy.

The median reduction in operational emissions reached 21%, substantially above the 11% average. Three-quarters of signatories reduced emissions from direct operations and purchased electricity, heat, steam and cooling. Dozens reported reductions of at least 50%.

The Pledge estimates that achieving its 2040 net-zero commitment across participating companies would eliminate at least 2.6 billion metric tons of CO₂e annually.

Yet progress remains uneven across emissions sources.

Indirect emissions from purchased electricity, heat, steam and cooling recorded the largest improvement, falling 35% on average. Renewable energy procurement was the main driver.

Direct operational emissions fell only 4%. Those emissions include fuel combustion and industrial processes, where decarbonization often depends on fleet electrification, redesigned operations and technologies that have not yet reached commercial scale.

For executives and investors, that divide highlights where the next phase of corporate decarbonization becomes more capital-intensive. Purchasing renewable electricity can deliver relatively rapid reductions. Transforming physical assets, logistics networks and industrial processes typically requires longer investment cycles and greater coordination.

Joint projects target harder-to-abate emissions

The Climate Pledge is increasingly using collective procurement and joint projects to address those barriers. It now has 33 joint action projects supported by 122 signatories. During 2025, nine projects brought together 44 companies to develop lower-carbon industry solutions.

Freight is one focus. The Electrifying Drayage Alliance, launched with Smart Freight Centre in 2025, brings together more than 45 companies to accelerate electric transport between ports and warehouses.

Another initiative, Laneshift, deployed 357 zero-tailpipe-emission electric trucks across India, Mexico and Brazil. The program avoided 3,215 metric tons of CO₂e during 2025 and generated 1,151 job-years, according to the report.

Buildings and construction are another target. The U.S. Department of Energy’s Commercial Heat Pump Accelerator is developing units designed to reduce HVAC energy use by 20% to 50%. A separate mass timber initiative targets embodied carbon reductions of 35% to 65% compared with conventional steel and concrete.

Work on lower-carbon concrete is also expanding. The Climate-Smart Concrete initiative aims for at least a 20% carbon reduction against regional baselines across North American markets. Separately, the Sustainable Concrete Buyers Alliance has engaged 33 companies to aggregate demand for lower-carbon materials.

The 2026 report points to a shift from corporate target-setting toward implementation through procurement, infrastructure and shared investment. For companies pursuing 2040 and 2050 climate goals, the harder test now lies in whether collaborative demand can accelerate technologies needed to decarbonize the physical economy at scale.
