UN: Emissions are falling too slowly
The current analyses of the United Nations show that global emissions do exhibit a tendency to decline, but the pace is not sufficient to reach the 1.5-degree target of the Paris Agreement. Despite progress in the quality of national climate plans (NDCs), a clear gap remains between current pledges and the reductions scientifically required.

Introduction
The question of whether emissions are measurably decreasing can be answered in a nuanced way: The curve is starting to bend, but not at the pace required for the 1.5-degree target ( UNFCCC). ). UN analyses project that with full implementation of the current plans, a global emissions reduction of about 10 percent by 2035 relative to 2019 would occur. However, about 60 percent would be necessary ( Reuters; WRI).
NDCs, the Nationally Determined Contributions, are national climate plans under the Paris Agreement. They set goals and measures for emissions reductions and adaptation and are published in the public NDC-Register published ( UNFCCC). ). Der NDC Synthesis Report summarizes these plans. The 1.5-degree path describes emission trajectories that limit warming to 1.5 degrees. For this, global greenhouse gas emissions must fall very rapidly: IPCC scenarios call for about 43 percent by 2030 and around 60 percent by 2035 ( WRI; IPCC). ). UNEP puts the need at about 42 percent by 2030 and 57 percent by 2035 ( UNEP).
Analysis of the NDCs
The UNFCCC has published the NDC Synthesis Report 2025 release. This includes 64 new NDCs, submitted between January 1, 2024 and September 30, 2025, covering about 30 percent of global emissions from 2019. According to the official report, these plans bend the joint emissions curve further downward, but not fast enough. UNFCCC).
For the group of submitting countries, with full implementation by 2035 an emission level would be about 17 percent below 2019, with a peak before 2030 ( UNFCCC). ). This partial statement does not allow direct conclusions about the world as a whole, but it highlights the need for further dynamism ( UNFCCC).

The Emissions Gap: How far the current climate targets are from the reductions needed to achieve the global warming targets.
Reuters sums up the global perspective: If one adds up all pledges and assumptions, global emissions could fall by 2035 for the first time – by around 10 percent compared with 2019. However, around 60 percent would be needed for 1.5 degrees ( Reuters). ). At the same time, the WMO warns that the next five years are very likely to bring record heat again – another sign of too slow action ( WMO).
Backgrounds and Motivations
The gap between the current plans and the 1.5-degree target has several reasons. First, many governments are in the tension between electoral and economic realism. Energy prices, industrial policy and social balancing mechanisms influence ambitions ( UNFCCC). ). Second, the dynamics shift from setting targets to delivering targets. Laws, grid expansion, permits and investments are now more decisive than headlines ( UNFCCC). ). Third, financial markets increasingly pay attention to transition risks, i.e., the danger that business models based on fossil fuels lose value. This increases the pressure to back credible 2030- and 2035-targets with concrete measures ( UNEP).

Fact-checking and reactions
Cited: The NDC Synthesis Report 2025 includes 64 new NDCs and attests for this subset a reduction of about 17 percent by 2035 compared with 2019, but with limited significance for the world as a whole ( UNFCCC).
Unclear: The exact size of the global decline by 2035 is unclear. Several major emitters have not yet submitted final plans or are in domestic political debates; model assumptions differ ( Reuters; UNFCCC).

The steady rise of global CO2 emissions underscores the challenge facing the global community.
False/Misleading: The claim that the 1.5 degrees are passé, so mitigation does nothing anymore, is misleading. Even if 1.5 degrees are temporarily exceeded, each additional tonne shortens the overshoot less and reduces risks. Rapid emissions reductions remain crucial ( IPCC; UNEP).
The UNFCCC emphasizes progress in the quality and breadth of the new NDCs, but calls for an acceleration in implementation and financing, especially for developing countries ( UNFCCC). ). Reuters notes that the expected global decline would be historic, but far below the 1.5-degree path ( Reuters). ). Analyses such as the Climate Action Tracker warn that current policies still run well above 2 degrees ( Climate Action Tracker).
Impacts and recommendations
For individuals, businesses and municipalities, concrete implications arise. First: Check your country's NDCs directly in the Register, , to learn about targets, timelines and sectors. Climate Action Tracker, Third: For companies, financial decision-makers and municipalities, it applies that 2030- and 2035-target paths should be backed by concrete investment and implementation plans. IPCC and UNEP benchmarks for 1.5-degree compatibility help with this ( IPCC; UNEP).

Open questions remain: How do late submissions change the overall picture by COP30? Which commitments will be legally and financially underpinned so that they are reliably implementable? What role do international cooperation, Article 6 instruments, and climate finance play for accelerated mitigation after 2030? Answers depend on further NDCs 3.0 and their implementation ( UNFCCC; UNFCCC).
Conclusion
The NDC Synthesis Report 2025 shows: Something is moving – but too slowly. For 1.5 degrees we need by 2035 global emission reductions on the order of 57–60 percent; currently the plans point to around 10 percent ( UNEP; WRI; Reuters). ). The good news: Many levers are known – from grid expansion to efficiency. The crucial question is no longer whether, but how quickly we implement ( UNFCCC).
