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!

    Planning for the cost of climate action: a practical guide for local governments

    Local authorities play a leading role in ecological planning. As major contributors to public investment they have core responsibilities that can significantly accelerate the transition, such as expanding public transport networks or retrofitting public buildings for energy efficiency. According to I4CE, in France, local authorities in France need to double their investments in decarbonization by 2030 -without even accounting for future adaptation costs.

    Transition plans and remuneration policies: what are the challenges for financial actors?

    Integrating climate indicators into variable remuneration is a burning issue. Although it was removed at the last minute from negotiations on the Corporate Sustainability Due Diligence Directive (CSDDD), the proposal is still very much alive in the policy debate . While the topic is becoming increasingly central to remuneration in large companies, it still appears to be a taboo within the banking sector. This requirement was already included in the European Central Bank’s supervisory guidelines as early as 2020, yet it appears to have been largely neglected by banks.

    The pathway for climate investments in turbulent times – annual report 2024

    We are witnessing a withdrawal of commitments to climate action. In the US, President Donald Trump does not hide his hostility to what he calls the ‘climate hoax’. In Europe and in France, new narratives around competitiveness, strategic autonomy and security are gaining ground, reflecting a new political reality. If there is still a broad consensus on the long-term objective of climate neutrality, how to get there is increasingly challenged, generating uncertainty. The scarcity of fiscal resources impacts the willingness to embark on the green transition.
