Deforestation of the Brazilian Amazon reached a record in June for the fourth consecutive month, according to official data released Friday.

A total of 1,062 square kilometers of forest was destroyed—an area almost the size of the city of Rio de Janeiro.

This was up from 1,043 km2 in the same month last year, said the INPE research institute, which uses to measure .

In total, 3,609 km2 of Amazon was lost in the first quarter of 2021, up 17 percent from the same period last year.

The figure was the highest for a month of June since the INPE started gathering data in 2015.

Since coming to power in 2019, far-right President Jair Bolsonaro has promoted the commercialization of the Amazon and described NGOs trying to protect the jungle as a "cancer."

However, he recently pledged to eliminate Brazil's illegal deforestation by 2030, some 10 years ahead of target, though environmentalists say he is insincere.

Last month, vice president Hamilton Mourao announced a against Amazonian deforestation.

Two weeks ago, Brazilian Environment Minister Ricardo Salles resigned after the Supreme Court ordered an investigation into allegations he was involved in a timber trafficking scheme.

He was replaced by Joaquim Alvaro Pereira Leite, allied to one of the country's largest agricultural lobby groups.

The Brazilian Amazon also marked its worst June for since 2007 this year, with some 2,308 fires detected—an increase of 2.3 percent from the same month last year.
