San Francisco Frontiers - Brazil's climate wins ahead of COP30

However, veteran leftist Luiz Inacio Lula da Silva faces a strong agribusiness lobby in congress that has tried to weaken environmental laws, and the president has enraged green activists with his support for the expansion of oil exploration.

This is what experts say he is doing right:

- Brazil's climate comeback -

The 79-year-old has returned to office after years of rampant Amazon deforestation under his climate-sceptic predecessor Jair Bolsonaro.

"Brazil is back," he declared at COP27 in Egypt shortly after his re-election, receiving a rock star's welcome as he pledged to protect a rainforest with billions of carbon-absorbing trees that are a key buffer against global warming.

He announced plans to host COP30 in the Amazon itself so world leaders could get a first-hand look at one of Earth’s richest ecosystems.

Another strong message was Lula's choice of environment minister, Marina Silva -- who cut deforestation dramatically during his first term.

The pair have previously feuded over the clash between development goals and environmental protection.

They set about rebuilding Brazil's environmental agencies and Lula also reactivated the Amazon Fund, an international financing mechanism to protect the forest that had been suspended under Bolsonaro.

- Slowing forest loss -

Lula pledged zero deforestation by 2030.

In the last year of Bolsonaro's presidency in 2022, deforestation reached more than 10,000 square kilometers (3861 square miles) -- an area about the size of the country of Lebanon.

This number had dropped by more than half by 2024, falling to 4,200 square kilometers.

However, in 2024, Brazil suffered one of its worst waves of forest fires on record. The flames, often linked to agricultural activity, grew out of control amid a historic drought linked to climate change.

Silva said fires had become one of the main causes of deforestation.

Forest loss also slowed in other sensitive biomes like the Cerrado, a vast region of tropical savannah in central Brazil.

- Indigenous lands -

Indigenous lands are seen as a key barrier to Amazon deforestation.

Lula created an Indigenous people's ministry and legalized 16 Indigenous reserves during his third term -- a process that had been paralyzed under previous governments.

Marcio Astrini of the Climate Observatory, a collective of NGOs, said the demarcation of Indigenous lands was particularly important in case a climate-sceptic candidate wins 2026 presidential elections.

"A new government can withdraw funding from climate policies, but it won't be able to undo a protected Indigenous area," he told AFP.

Government policies also expelled invaders from more than 180,000 square kilometers of Indigenous lands -- an area slightly smaller than Uruguay -- according to the state Indigenous affairs agency Funai.

Local populations "regained freedom to move around, resume hunting...they recovered their territory," Nilton Tubino, coordinator of Indigenous policies for the federal government in the northern Amazon state of Roraima, told AFP.

- Financing forest protection -

Brazil's government has also designed a global initiative to finance the conservation of endangered forests: the Tropical Forest Forever Fund (TFFF).

"This is the main contribution Brazil intends to make to the COP," said Finance Minister Fernando Haddad.

Authorities envision the TFFF as a fund of more than $100 billion in public and private capital.

Three weeks ago, Lula announced that Brazil would invest $1 billion in this initiative during a speech in New York on the sidelines of the UN General Assembly.
