Emissions Gap Report 2024

As the world prepares for the next round of Nationally Determined Contributions (NDCs) in early 2025, there’s a clear imperative: nations must not only promise ambitious greenhouse gas cuts but also deliver them decisively. The numbers are stark—a 42% reduction in emissions by 2030 and 57% by 2035 is essential to keep the 1.5°C climate goal within reach. Missing these targets could result in devastating consequences, with global temperatures set to rise by 2.6-3.1°C by century’s end, intensifying climate impacts on communities, ecosystems, and economies.

The path to 1.5°C remains technically achievable, largely through the rapid deployment of solar and wind energy, as well as large-scale reforestation. But achieving these targets requires more than pledges; it demands a concerted, immediate push across governments, industries, and societies worldwide. Here’s what’s essential:

1. Strengthened NDC Ambitions and Immediate Action: Updated and ambitious NDCs are the first step, but they must be followed by prompt implementation. With each nation holding responsibility, G20 countries, in particular, need to lead the way as they account for a significant share of global emissions.
2. A Whole-of-Government Strategy: Cutting emissions at the scale needed requires comprehensive, all-in participation. Policies that enhance both environmental and socioeconomic outcomes—like job creation in renewable sectors and environmental justice for frontline communities—can ensure widespread support for these efforts.
3. Enhanced International Collaboration and Financial Reforms: Reforming global financial systems to support climate initiatives is crucial, with international partnerships ensuring that resources and technologies are accessible to all nations. Transformative financing can enable developing countries to meet their NDCs and bolster resilience.
4. Private Sector Engagement and Significant Investment Upsurge: The private sector holds enormous potential to accelerate emissions reductions, and investments in climate mitigation must increase six-fold to meet the necessary pace. Carbon markets, green bonds, and sustainable investing can drive this growth, directing funds toward high-impact areas.

The 2025 NDC update is a critical moment to recalibrate and boost climate ambition. Each additional increment of warming avoided matters, and the collective effort to maintain 1.5°C is the key to a safer, more resilient world.
