Unlocking Climate Action: How Nationally Determined Contributions Drive Effective Climate Policy

In 2015, almost every nation signed the Paris Agreement, a big step toward tackling climate change. At its heart are Nationally Determined Contributions (NDCs). These are essentially climate plans that countries create to show how they will cut greenhouse gas emissions. Each nation’s plan reflects its unique strengths and priorities, making NDCs crucial for guiding and tracking climate efforts.

Over the last decade, NDCs have helped limit global warming projections for 2100 to 2.1-2.8°C. If all countries meet their NDCs, emissions could drop by 14% by 2030. However, we still have a long way to go. We need a 43% cut to stay under 1.5°C. Challenges like political tensions and economic uncertainty have slowed progress, amplifying the risks of climate-related disasters.

Countries must update their NDCs every five years, increasing ambitions to reflect new technologies and growing urgency. For instance, the UK aims to cut emissions by 81% below 1990 levels by 2035. Similarly, the US targets a 61–66% reduction from 2005 levels by the same year. The EU is aiming for a 40% reduction by 2030, though its formal update is still pending.

This upcoming round of updates in 2025 is vital for closing gaps in global climate action and advancing toward net-zero emissions. A recent report by the OECD and UNDP emphasizes that enhanced NDCs can lead to stronger economic growth while addressing climate change, showcasing how sustainability can also be a path to economic prosperity.

For countries to support their enhanced NDCs effectively, collaboration across government sectors is essential. This includes integrating climate goals into financial planning and ensuring alignment across various departments. Public support is crucial too, as half the world lives in cities responsible for 70% of emissions. Local governments play a key role in implementing climate policies.

The report suggests a few clear steps. First, integrate NDC targets into fiscal planning. Second, use revenue-raising methods like carbon pricing. Third, leverage public procurement to meet climate goals. This coordination fosters a stable investment climate, encouraging businesses to support low-carbon innovations.

The OECD’s analysis predicts that implementing these enhanced NDCs can boost the global economy. Global GDP can grow 60% by 2040, compared to 2022 levels, while simultaneously reducing emissions by 34%. Interestingly, developing countries could see the greatest benefits, as investments tied to climate policies can spur growth where it might otherwise stall.

Though the immediate economic impact might seem minimal, significant shifts will occur in energy production. The transition away from fossil fuels toward renewable energy will require careful planning and significant investment. Bank coordination is critical to accommodate the possible inflation from these policies, ensuring that investment levels remain high.

In the long haul, minimizing climate damages will reap major benefits. With committed climate action, we could limit warming to 1.7°C by 2100 compared to 2.4°C with current policies. This reduced warming translates to fewer extreme weather events and lower physical and economic risks, protecting ecosystems and communities alike.

Committing to enhanced NDCs not only tackles climate issues but also secures a safer and more resilient future. It’s about making environment-friendly choices that benefit everyone, driving us toward a sustainable economy and a healthier planet.
