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!

    How to strengthen climate risk management and supervision to protect financial stability

    Climate change does not conform to business, political or supervisory regime cycles– its adverse long-term impacts lie beyond such horizons. Ten years ago, when Mark Carney highlighted this paradox in his landmark Tragedy of the Horizons speech, climate change was not considered a financial stability risk. Today, European supervisory stress tests estimate up to €638 billion in banking losses over 8 years, while the European Central Bank (ECB) reveals that over 90% of eurozone banks face climate and environmental risks. A key question arises: Is the supervisors’ primary focus on greening the financial system sufficient in the face of rising risks, especially stranded assets?

    How solidarity levies can help bridge the climate and development finance gap

    The climate and development finance gap is large and widening, as Official Development Assistance (ODA) declines and needs multiply. With shrinking fiscal space in vulnerable countries, solidarity levies are gaining attention as a predictable source of international finance. Launched at COP28 by Barbados, France, and Kenya, the Global Solidarity Levies Task Force (GSLTF) is the main initiative in this space.

    COP30: On Financing, the Time for Negotiation Is Over

    “What agreement will the negotiators reach?” is the question that is usually on climate practitioners’ minds at this time of the year. However, this time, it is a new impetus that is needed, not another agreement. 10 years after the Paris Agreement, the Brazilian COP30 presidency has rightly shifted the focus to execution, making this edition “the implementation COP.” On financing, the objectives set at COP29 are clear: developing countries should receive $300 billion per year by 2035 from developed countries (NCQG), and mobilise $1.3 trillion per year from all actors. The newly published “Baku to Belém” roadmap proposes solutions to meet the targets. We now have objectives and a list of (theoretical) means to achieve them. How do we move to implementation?
