The five environmental candidates only have a few days left to convince and try to win in the primary, the first round of which will take place from September 16 to 19. After a first debate on Sunday where they carefully avoided scratches and small murderous phrases, they met on Wednesday evening for a new televised confrontation on LCI, in an atmosphere always very civilized. Most of the nearly two-hour broadcast was devoted to substantive ecological debates.

Asked like all the candidates on the first measure he would implement if he were elected president, Yannick Jadot defended the end of factory farming. Praised by EELV sympathizers in the polls, the EELV MEP, who enjoys the most important notoriety, defended “a combat ecology” in particular against lobbies and free trade treaties, while insisting: “it is also a solution ecology ”. The candidate wanted to present himself as a unifier of society: “the ecology that I wear is a way of bringing all French people together around a project,” he argued. Among other measures, Yannick Jadot defended the ban on the sale of heat engines by 2030, or the release of a billion to effectively combat violence against women.

The mayor of Grenoble started the debate by defending his flagship measure, a constitutional referendum “to unlock democracy”. The candidate wants to include in the constitution the guarantee of the climate and the environment as well as the referendum of popular initiative. On the theme of transport, Éric Piolle advocates the development of the freight train, the taxation of the heaviest vehicles or even a limited use of airplanes. He again defended his proposal to create a climate ISF which he said could generate 8 billion euros. With an argument to the key: “The wealthiest 1% of the world’s population emit twice as much as the least fortunate 50%”.

The first to have declared herself a candidate for primary school, the academic and former number two of EELV takes as a first measure the establishment of a pact of social and ecological dignity, with in particular the establishment of an income from existence of 850 euros, a health plan and a legal status for animals. On certain subjects, she did not hesitate to assert herself in the face of her opponents, such as degrowth: “Degrowth is not the subject. The subject is the sharing of wealth “she retorted to Delphine Batho. “It will take courage and we will have to make choices. This is what we are missing today. ” The one who clearly defined herself as a “left-wing environmentalist” also allowed herself one of the few tackles of the evening. To the centrist candidate Jean-Marc Governatori who hinted that he would not support the winner chosen by the primary, she swung: “You will not be able to win”.

François Hollande’s former Minister of Ecology took his spokesperson, ex-deputy LREM (and former candidate for mayor of Paris), Cédric Villani, to the stage. If she were elected President of the Republic, her first step would be to issue a decree to immediately ban pesticides and endocrine disruptors. She also defended degrowth, which is the cornerstone of her program. She considers that the GDP is an obsolete indicator and proposes to replace it by an indicator of social health for example. The deputy for Deux-Sèvres urged her opponents to have a clear position on the subject: “either we are for growth, or we are for degrowth,” she insisted. While hammering twice his rejection of “presidentialism”.

Former entrepreneur and city councilor in Nice, Jean-Marc Governatori wore, as in the previous debate, a green jacket. He once again defended a “pragmatic and centrist” view of ecology. The first decision he would make would be to hold a major six-month national debate on education, with a referendum at the end of it. The co-president of Cap Écologie stood out in particular on the subject of the legalization of cannabis, being the only one to be opposed to it. He also made his difference heard by asserting at the end of the evening that the other candidates at his side on the set “were there to bring together the left”.

The five candidates will meet on Friday for a third debate on the Mediapart site before a confrontation, again on LCI, between the finalists during the in-between rounds on September 22.
