COP21 – a successful ‘end of the beginning

The Paris Agreement provides a clear signal and a solid framework for climate action. Balanced and ambitious in its objectives – including full decarbonization of the global economy before the end of the century – it has all the conditions to encourage everyone to do more.

In establishing a new international climate change regime, the Agreement focuses on the essentials: guiding countries towards low-carbon and climate resilient economies. The main challenge resides not in the direct implementation of the decisions taken in Paris, but rather in the alignment of countries’ national strategies with a decarbonization trajectory.

COP21 marks the advent of a new regime of international cooperation rather than a ‘utopian’ and politically unpalatable system to punish or coerce States to take action. It confirms the desire to engage both State and non-State actors on climate action. In this respect, it is a real victory of multilateralism.

Indeed, COP21 marks the “end of the beginning” of a long negotiations process to shift to a permanent regime, completed by regular appointments to boost ambition. This victory, however, will become historical only if this cooperation leads to enhanced action and concrete results. And this is where the hard work begins!

    Stay the course: why a stronger ETS is the key to industrial competitiveness 

    Since 2005, the EU Emissions Trading System (EU ETS) has been a cornerstone of Europe’s climate policy. With the price per tonne of CO2 now beginning to stabilise at between €60 and €80, and the gradual reduction in free allowances, 2026’s review of the system should be an opportunity to reflect on and upgrade its performance as the EU continues towards climate neutrality.

    To strengthen European industry, let’s strengthen the ETS

    Several voices are now being heard in Europe, coming from Member States – including that of Chancellor Merz – and from industry, calling for the rules of the CO2 quota system to be weakened. For Benoît LEGUET and Jean PISANI-FERRY, this would be a mistake for Europe. And for France. On the contrary, we must strengthen this unique public policy in order to develop our industry.

    Risk levels and priorities: financing climate adaptation requires clear decisions

    As the European Commission prepares an integrated framework on climate resilience and risk management for the EU, the public consultation has just wrapped up – an important step towards the publication of the proposals for the framework later this year. One of the main areas of focus will be the issue of financing adaptation, with the first key challenge being to mainstream the concept of resilience by design into all European funding currently under discussion, including structural policies such as the Common Agricultural Policy and the Connecting Europe Facility.
