Leaders from poor countries criticized wealthy governments and oil companies for driving global warming, using their speeches on Tuesday at the COP27 climate summit in Egypt to demand that they pay up for damages being inflicting on their economies.

Small island states already buffeted by increasingly violent ocean storms and sea-level rise called on oil companies to shell out some of their huge recent profits, while developing African states called for more international funds for adaptation.

“The oil and gas industry continues to earn almost 3 billion United States dollars daily in profits,” said Gaston Browne, Antigua’s prime minister, speaking at the conference on behalf of the Alliance of Small Island States.

“It is about time that these companies are made to pay a global carbon tax on their profits as a source of funding for loss and damage,” he said. “While they are profiting, the planet is burning.”

Nikenike Vurobaravu, the president of the island nation of Vanuatu, said it wanted the International Court of Justice to help ensure future generations’ rights were not being violated by nations lagging on climate change.

The comments reflected the tension in international climate negotiations between rich and poor states, as delegates attended the second full day of the two-week U.N. conference in the seaside resort town of Sharm el-Sheikh.

Wealthy western countries tend to be the most vocal advocates of slashing emissions, but are also the ones that have contributed the most greenhouse gases after more than a century of fossil fuel-driven industrialization.

Multi-billion-dollar oil industry profits since Russia’s invasion of Ukraine in February – which has roiled markets and disrupted supplies – have also angered governments worldwide concerned about climate change and rampant consumer inflation.

U.S. President Joe Biden this month said the industry was raking in “war profits” and proposed a windfall tax, an idea that has little chance of passing a divided Congress.

But some countries at the conference were more likely to direct their frustration at rich governments, not drillers.

Senegal’s President Macky Sall told the conference poor developing countries in Africa needed increased funding from wealthy nations for adaptation to worsening climate change, and would resist calls for an immediate shift away from fossil fuels African countries need to fuel their economies.

“Let’s be clear, we are in favor of reduction of greenhouse gas emissions. But we Africans cannot accept that our vital interests be ignored,” he said.

Chandrikapersad Santokhi, president of Suriname – a South American nation whose forests absorb more carbon than its people emit – said wealthy countries needed to uphold a promise to direct $100 billion a year to developing countries for climate adaptation.

“On behalf of all children and the next generation we urgently call on historic emitters to do their part to safeguard our world. My country is doing our part with the limited resources and capacity,” he said.

The hosts of the COP27 climate talks on Tuesday launched a global plan to help the world’s poorest communities withstand the impacts of global warming, including targets for sustainable farming, mangrove restoration to reduce coastal flooding, and access to clean cookstoves.

The head of the World Trade Organization, meanwhile, told Reuters she aimed to revive negotiations on a global environmental trade deal as part of efforts to give the trade watchdog a bigger role in tackling climate change.

BILLIONS FOR WAR

Sri Lanka’s president, Ranil Wickremesinghe, said governments were quick to divert billions of dollars to the war in Ukraine, but slow to spend serious money on climate change.

“Double standards are unacceptable,” he said.

Scores of other heads of state and government spoke on Monday and Tuesday but many of the world’s biggest polluters – including the United States, China and India – have yet to hit the podium.

Biden will not arrive until Friday – after Tuesday’s midterm elections in the United States – but his delegation opened its pavilion at the COP27 venue on Tuesday and Special Envoy John Kerry was making the rounds.

Conference host Egypt was facing pressure over its jailing of Egyptian-British blogger Alaa Abd el-Fattah, who rose to prominence during Egypt’s 2011 popular uprising but has been detained for most of the time since and is now on hunger strike.

His family said on Tuesday they had not heard from him since he had been due to stop drinking water two days ago.

Egyptian President Abdel Fattah al-Sisi’s government came to power after heading the 2013 overthrow of Egypt’s first democratically elected leader, and has drawn human rights criticism after subsequent bloody crackdowns on protesters and the detention of dissidents.

His government has been hoping its hosting of the COP27 conference would give it an injection of international legitimacy at a time its economy has been struggling.
