France and the European Union need independent scientific experts to guide them on divisive environmental issues such as pesticides, French President Emmanuel Macron said, criticising some research as prone to lobbying pressures.

The EU has struggled to find a consensus on farming questions such as pesticides and genetically modified crops, and is still debating whether to extend the licence of popular weedkiller glyphosate.

In a speech on food and farming on Wednesday, Macron reiterated France’s support for phasing out glyphosate, and argued that independent expertise along with investment in innovations would bring solutions to environmental problems.

“I would like us to be able to bring together the conditions whereby we can have independent scientific expertise on each of these (environmental) subjects and that we have the same requirements at EU level,” he said.

“We have endured too much pressure in recent years on these questions, too many hidden interests and industry expertise that is in no way scientific expertise.”

He repeated a pledge to change the law in France to prevent suppliers from simultaneously selling pesticides and advising farmers.
