What is an NDC?
An NDC (Nationally Determined Contribution) is a climate action plan that each member government must create and commit to as part of the Paris Agreement.

These contributions outline how each country intends to reduce its greenhouse gas emissions and adapt to the impacts of climate change. Importantly, the country gets to set its own contribution - i.e. it is ‘nationally determined’. 
 
WWF’s NDCsWeWant Checklist signals important characteristics for a robust NDC, this includes elements such as just transition, integration of sustainable development goals and promoting climate justice.

Why are NDCs important?

NDCs are central to the global effort to limit global warming to well below 2°C, ideally aiming for 1.5°C above pre-industrial levels.

They set out countries' climate targets and action plans, and are updated periodically (typically every five years) to reflect a country's progress and increased ambition in addressing climate change. Each country's NDC is unique and considers its economic, social, and environmental circumstances. 

The implementation of the action plans set out in each NDC will ultimately determine whether we are able to meet our climate goals and limit the catastrophic consequences of the climate crisis.

What do we mean by ‘climate ambition’?

Climate ambition is a term used to describe the promises and commitments made by countries to reduce greenhouse gas emissions and increase resilience to the adverse impacts of climate change. Countries nationally determine how to translate this into activities and promises, and so in a sense the definition of climate ambition is also defined by each country.

However, the Intergovernmental Panel on Climate Change (IPCC), which publishes scientific assessments on climate change, is widely accepted as providing the most relevant information on what commitments and activities are needed to address climate change, and tends to be a benchmark to which countries’ climate ambition is considered.

This includes measurable, time bound national climate target(s), such as quantified emissions reductions for 2030, 2035, 2050, etc. It also includes other aspects including sector emission reduction targets, technology investment or action plans.
