Protest in Paris over proposed new climate law

French demonstrators took to the streets of Paris and other cities on Sunday to call for more ambitious measures to fight against climate change.

The protests come after the lower house of parliament voted this week on a climate bill aimed at curbing greenhouse gas emissions that environment activists say doesn't go far or fast enough.

Greenpeace France denounced "the government's refusal to take action for climate."

Activists blame President Emmanuel Macron, who has been very vocal about his support for climate change action, for having "weakened" a set of measures initially proposed by a panel of 150 citizens who had worked for months on the issue.

The bill is now set to be debated in the Senate.

It includes a ban on domestic flights under two and half hours that can be done by train, measures to support renovation of high energy-consuming buildings and to encourage greener cars.

In addition, French newspaper Journal du Dimanche on Sunday reported that a referendum to add the need to preserve the environment into the French constitution, promised by Macron, cannot take place.

The change requires a parliamentary vote.

The National Assembly, where Macron has a majority, largely approved it in March.

But no deal has been found with the Senate, where the conservative party The Republicans hold the majority.

Macron's office said the measure "is not abandoned ... the battle continues. The environment issue remains one of the priorities of the president."

About a third of France's 100 billion-euro ($122 billion) rescue plan to help the economy recovering from the virus crisis by next year will go to reducing emissions and protecting biodiversity, Macron's office stressed.

Macron also pushed for beefing up the European Union's 2030 targets to reduce greenhouse gases by at least 55% compared with 1990 levels — up from the previous 40% target.

The EU in April reached a tentative climate deal to put the 27-nation bloc on a path to being "climate neutral" by 2050.
