France’s government is pumping 15 billion euros ($16.9 billion) in rescue money into the pandemic-battered aerospace industry, in hopes of saving its hundreds of thousands of jobs and keeping plane-maker Airbus and national airline Air France globally competitive.

In exchange for aid, companies will be required to invest more and faster in electric, hydrogen or other lower-emission aircraft, as France aims to make its aviation industry the "cleanest in the world."

The deal was negotiated with unions, who said they would stay vigilant about job guarantees. Some environmental activists expressed skepticism about green ambitions for such a high-emission industry.

"We will do everything to support this French industry that is so critical for our sovereignty, our jobs and our economy," Finance Minister Bruno Le Maire said, unveiling the plan alongside the ministers of transport, defense and environment – a sign of how important the aeronautic sector is in France.

The French aid money includes direct government investment, subsidies, loans and loan guarantees. It also includes a special fund jointly financed by the government, Airbus and other big manufacturers to support small suppliers.

It includes 7 billion euros in loans and loan guarantees that the government had already promised to Air France, whose planes were almost entirely grounded by the virus.

And like a similar multi-billion-euro plan to save the French car industry announced last month, the aviation bailout requires more investment in clean energy – and puts pressure on manufacturers to avoid layoffs.

It will aim at modernizing the production chain and preserving European aviation know-how, Le Maire said.

"We must save our aeronautical industry. We must avoid any decline in the coming months with regard to the American giant Boeing and the Chinese giant Comac," he said. "We won’t let the world aeronautical market be shared between China and the United States. France and Europe will retain their position."

The government will help Air France buy Airbus planes, and pledged to order 600 million euros worth of refueling tankers, drones and helicopters from Airbus' defense arm. In addition to dominating the global passenger aircraft market alongside Boeing, Airbus is also a major supplier of military aircraft to European governments.

"The recovery will be long," Le Maire warned. The government predicted it will be 2023 before the industry reaches pre-crisis levels.
