UNEP Report Links US Emission Surge To Global Climate Goals Failure

A United Nations Environment Programme report published recently indicates that rising United States carbon emissions are pushing best-case climate scenarios out of reach. The findings highlight how domestic policy changes in the US are undermining international efforts to cut carbon and avoid the worst impacts of climate change.

How much did US emissions rise?

Scientists with the United Nations Environment Programme found that US carbon emissions rose by 133 megatons last year. This increase far exceeded the emission rises seen in all other major economies. The surge was driven by increasing electricity demand and a rebound in coal power generation, according to the report.

What policies drove this increase?

The report states that Trump administration policies helped drive the emission increase and worsened projections. By 2030, emissions are expected to be nearly 0.9 gigatons higher than projections based on Biden-era policies. The administration repealed most Inflation Reduction Act climate policies under the One Big Beautiful Bill Act and rolled back vehicle and power plant standards.

What are the global consequences?

The consequences of American climate inaction will be felt globally, with US emissions disproportionately worsening the crisis. The US tied with Russia for the highest per capita carbon emissions at nearly 18 tons. Formal withdrawal from the Paris Agreement for the second time has made its original goal of limiting warming to 2.7 degrees Fahrenheit effectively unachievable.

What cuts are needed now?

The new UNEP report outlines emissions cuts needed to limit overshoot, aiming to keep peak warming around mid-century below 3.1 to 3.2 degrees Fahrenheit. Global emissions cuts of 18% by 2030 and 45% by 2035 will be necessary for this best-case scenario. This requires increasing carbon dioxide removal over the course of the century alongside significant reduction efforts.

Questions to ask your suppliers

Organizations should ask suppliers how regulatory shifts in key markets affect their operational continuity and carbon reporting requirements. Procurement teams need to determine if vendors have updated their sustainability disclosures to reflect new US policy realities. Risk managers should verify whether supply chain contracts include clauses for compliance with changing environmental standards. Internal stakeholders must understand how these macro-level policy changes impact long-term procurement costs and vendor stability assessments.

What to do and how to stay safe: UNEP

• Review current vendor contracts for clauses related to environmental compliance and regulatory changes.
• Update risk assessments to account for potential supply chain disruptions caused by policy shifts.
• Monitor official government announcements for further deregulation or policy reversals affecting your sector.
• Ensure internal reporting mechanisms can capture changes in supplier sustainability practices and carbon data.
