周二在COP27會議上私下會見盧拉的巴西青年活動家告訴BBC新聞，與一位 "想要解決問題 "的總統討論氣候危機是 "了不起的"。
The election of the left-wing leader has been called the best news for the climate in 2022, as he promises to end deforestation of the Amazon rainforest.
In order to make progress on his agenda, Ms Texeira said Lula would need to convince people and Congress members to agree, not disagree with each other.
He says Brazil is back in the climate game, but that civil society will not hesitate to challenge the new government it if fails to keep its promises.
"The world needs to be prepared for mistakes or failures. It's a complicated problem and we will face disappointments because of the political situation in Brazil," he said.
Young Brazilian activists at COP27 who met Lula privately at COP27 on Tuesday told BBC News that it was "amazing" to discuss the climate crisis with a president "who wants to solve the problem".
"It was amazing for us, including in the young black community, to meet our new president to talk about climate, something we've worked on for so long", said Vinicius Lopes.
There is concern too that the crucial aim to limiting temperature rise to 1.5C - which scientists say is crucial to avoiding the worst effects of climate change - is in jeopardy.
