Leaders of the world’s most advanced nations are gathering on Saturday in-person for the first time since the pandemic.
The two-day talks in Rome makes headway on tackling global warming, ahead of the key COP26 summit kicking off in Glasgow Monday.
The stakes are high, with United Nations Secretary General Antonio Guterres warning G20 leaders on Friday to show “more ambition and more action” and overcome mistrust in order to advance climate goals.
“We are still on time to put things on track, and I think the G20 meeting is the opportunity to do that,” Guterres said.
Security was tight in Rome as US President Joe Biden arrived in the Italian capital anxious to turn a page from the tumultuous Trump years and show that American leadership on the world stage is restored.
Yet the Democrat faces a credibility test as his own signature climate policy – part of a sweeping economic package – is held up amid infighting within his party in Congress.
Absent from the G20 will be Russia’s Vladimir Putin and China’s Xi Jinping, who plan to attend by video link.
Although no new pledges are expected on Covid-19 vaccines at the G20, a press release from a Friday meeting of G20 finance and health ministers stated that members would “take steps to help boost the supply of vaccines and essential medical products and inputs in developing countries and remove relevant supply and financing constraints.”
Summit host Mario Draghi, the Italian prime minister, has called for a “G20 commitment on the need to limit the rise in temperatures to 1.5 degrees” above pre-industrial levels, the most ambitious target outlined in the 2015 Paris Agreement on climate change.
On Friday, British Prime Minister Boris Johnson – the host of the UN talks next week – gave a dire warning of what could happen if the world failed on the climate crisis.
“We are not going to stop global warming in Rome or in this meeting in COP,” he told reporters aboard his plane to Rome. “The most we can hope to do is slow the increase.”
Complicating the task for the G20 will be disparities between top world powers on tackling global warming.
China, the world’s biggest polluter and responsible for more than a quarter of all carbon emissions, has been accused of sidestepping calls to stop building new coal-fired power plants.
A new plan submitted by Beijing to the UN ahead of COP26 fell short of environmentalists’ expectations, with a target date of 2060 to reach carbon neutrality.
Brazilian President Jair Bolsonaro, meanwhile, has steadfastly demanded that his country be paid for protecting its share of the Amazon.
Taxing global players
A surer bet for concrete progress at the G20 involves taxation, as the group is expected to endorse the 15 percent minimum international tax rate on multinational companies after nearly 140 countries reached an OECD-brokered deal.
The move seeks to end tax optimisation, in which global corporations – including big US tech firms like Apple and Google parent Alphabet – shelter profits in countries with low-tax systems.
The OECD says a 15 percent global minimum corporate tax rate could add $150 billion annually to global tax revenues.
G20 finance ministers gave their backing to the tax overhaul in July.
