Le Haut conseil pour le climat (HCC) est un organisme indépendant chargé d’évaluer la stratégie du gouvernement en matière de climat, et sa cohérence avec les engagements européens et internationaux de la France, en particulier l’Accord de Paris, l’atteinte de la neutralité carbone en 2050, et le respect des budgets carbone de la France.

Our role

The High Council on Climate (HCC) is an independent body tasked with issuing advice and recommendations to the French government on the delivery of public measures and policies aimed at reducing France's greenhouse gas emissions. Its purpose is to provide independent insight on government climate policy. The HCC was established on 27 November 2018 by the President of the Republic and then by Decree in May 2019. Its members are chosen for their expertise in the fields of climate science, economics, agronomy and energy transition.

The High Council on Climate has two strategic priorities:

— We submit an annual report on France’s adherence to its greenhouse gas emissions reduction trajectory and on the effective delivery of measures and policies to reduce greenhouse gas emissions and develop carbon sinks.

— We issue a report every five years on France’s low-carbon strategy and carbon budgets proposals, as well as on the greenhouse gas emissions reduction trajectory it committed to follow. It monitors the coherence of the low-carbon strategy with national policies and France's European and international pledges, in particular the Paris Agreement and the “carbon neutrality” goal by 2050.

To achieve these two objectives, the HCC considers the socio-economic impacts of the transition for households and businesses, key sovereignty issues and environmental impacts.

The HCC’s reports, based on analyses, assess current and planned policies and measures and outline recommendations and proposals to help France achieve its targets. These reports yield independent, factual and rigorous insight into France's greenhouse gas emission trends and its public policies. The HCC provides a long-term perspective and its publications are public. 

Our objectives

1. To have a significant impact on French policies and reduce GHG emissions

The High Council on Climate provides a long-term perspective, grounded in the most recent scientific knowledge. We aim to see our advices and recommendations directly reflected in key programmatic legislation, public policies and decisions adopted by French public actors at European, national, regional and local level.

2. Include adaptation to climate change

Climate change is taking a devastating toll on France and countries all over the world. In 2020, the HCC will already be considering the challenges associated with adaptation so as to recommend measures in this respect.

3. Communicate with all stakeholders

The energy transition will involve all sectors at all scales. This calls not only for cross-cutting policies but also greater communication. The HCC seeks to engage with all of the relevant stakeholders, public and private alike, at regular intervals.

4. Operate at international level

Limiting global warming and its consequences for populations and biodiversity requires global collaboration and action. Increasing numbers of countries are raising their national targets in the wake of the Paris Agreement and establishing independent scientific bodies to support their government. We are committed to working with all the advisory councils at international level, in a bid to share our national experiences and build a cross-border platform for dialogue.

France plays an instrumental role within the European Union. Our work also aims at helping the Government to put forward ambitious proposals at European level.
