To contribute to the goals of the agreement, countries presented comprehensive national climate change plans (national fixed contributions, NDC). These are not yet sufficient to meet the agreed temperature targets, but the agreement points to the way forward for further measures. So what should be addressed in the Paris Agreement if we are to put in place stronger international measures on climate change, which are now mobilizing action and which encourage even more action in the years to come (we will outline these key elements in our new `exit letter`? In response to the climate challenge, the agreement recognizes that states have common but differentiated responsibilities, i.e. according to their national capabilities and specificities. If we get the right parts of the Paris result, we can reach a permanent agreement to do even more in the years to come. After all, the first step is often the most difficult. It will not be easy, but citizens are calling for climate protection, so heads of state and government must rise to the challenge. The Paris Agreement will not “solve” climate change, but it can be a critical turning point. It brings us much closer to a safer climate curve and points the way to Paris. The Paris Agreement provides a sustainable framework that guides global efforts for decades to come.
The aim is to increase countries` climate ambitions over time. To achieve this, the agreement provides for two review processes, each in a five-year cycle. The agreement must strengthen future measures by putting in place systems for countries to improve their targets, as the best estimates show that these targets do not yet put us on the necessary climate path. Therefore, a critical outcome of the Paris Agreement is a robust process of reassessing and deepening emissions reduction commitments every five years. This process must begin no later than 2020, so that countries can reassess their efforts and commit to doing more by 2030. We need another political moment, well before 2030, so that countries can explain in detail the increased efforts. Finally, further reductions in the cost of clean energy, confidence that policies lead to a greater reduction in expected emissions and other factors will inevitably prove to heads of state or government that they can do more by 2030 than they are prepared to mention in detail in 2015. This is not an intrusive process, but it will allow countries to show that they are ready to play an even greater role in climate change by strengthening their national climate targets.
