本論文は、複数のモデルを用いた分析により、現在のネットゼロ誓約が世界を2°C未満の経路に近づけるが、排出ギャップが残ることを示す。野心の向上と国際協力が重要であり、1.5°C目標の達成は困難になりつつある。エネルギー効率の改善、石炭の段階的削減、運輸・重工業の電化が排出削減の鍵である。
English
Using a multi-model analysis, this paper shows that current net-zero pledges bring the world closer to a well-below 2°C pathway, but an emission gap remains. Increasing ambition and international cooperation are crucial, while reaching the 1.5°C goal without overshoot seems increasingly unlikely. Emission reductions are driven by energy efficiency, coal phase-down, and electrification of transport and heavy industry.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は2050年ネットゼロ目標を掲げており、本分析は誓約の実現と野心の向上が不可欠であることを示す。エネルギー転換の具体策として、電化や省エネの推進が日本でも重要。
In the global GX context
This study provides a global perspective on the gap between net-zero pledges and Paris Agreement goals, highlighting the need for increased ambition and implementation. It reinforces the importance of aligning domestic policies with climate commitments, relevant to global disclosure frameworks like TCFD and ISSB that track progress.
👥 読者別の含意
🔬研究者:Climate modelers and policy analysts can use the multi-model comparison to understand the range of possible outcomes under current pledges and the importance of rapid action.
🏛政策担当者:Policymakers should note the finding that net-zero pledges are promising but insufficient, and that stronger domestic policies are needed to close the emissions gap.
📄 Abstract（原文）
Climate targets require strong commitments from countries to be achieved. Using a multi-model analysis, we show that current net-zero pledges bring the world closer to a well-below 2 °C pathway, but an emission gap remains. Increasing ambition will be crucial: expanding the global coverage of net-zero pledges and speeding up action increases consistency with the Paris Agreement (1.5–2.0 °C range in model mean). However, reaching the 1.5 °C goal without overshoot seems increasingly unlikely. While net-zero pledges help reduce carbon-intensive energy sources, domestic policies aligned with strong climate commitments are needed to reduce the reliance on fossil fuels and increase renewable energy capacity. Our scenarios show that emission reductions are driven by gains in energy efficiency, a strong phase-down of coal use and the electrification of sectors such as transport and heavy industry. It is important to assess the gap between national climate ambitions and the goal of limiting global temperature increase. This multi-model analysis shows that if net-zero pledges are implemented, meeting the 2 °C target is feasible, while increasing ambition and international cooperation is crucial.
