Who should foot the climate finance bill – from loss and damage funds to new funding targets – has become an enduring controversy at recent COPs.
Experts have said that at least $1 trillion (€948 billion) needs to flow to developing nations by 2030 and a new climate finance goal known as the new collective quantified goal (NCQG) hangs in the balance in Baku.
Rich countries are calling for the pool of contributors to be widened. As developing nations deal with the growing frequency and scale of climate disasters, the urgency for these funds increases.
There are big gaps that rich nations will need to fill with innovative forms of finance. From levies on high carbon activities to wealth taxes, what are some of the alternative ideas on the table for raising this cash?
Simple solutions or difficult diplomacy?
A study published by civil society group Oil Change International in September found that rich countries could raise five times the money developing nations are demanding in climate finance with a series of what it calls “simple measures”.
According to the study, a combination of wealth and corporate taxes, taxes on fossil fuel extraction and a crackdown on subsidies could generate $5 trillion (€4.7 trillion) a year – five times what developing nations say they need.
Stopping fossil fuel subsidies alone could free up $270 billion (€256 billion) in rich countries and a tax on fossil fuel extraction could raise $160 billion (€152billion). A frequent flyer levy could total $81 billion (€77 billion) a year from the rich world and increasing wealth taxes on multimillionaires and billionaires would raise a staggering $2.56 trillion (€2.43 trillion). In total, the list of measures it proposes would raise $5.3 trillion (€5.02 trillion) a year.
Some of these options are likely to be easier to implement than others. While adding a levy for frequent fliers doesn’t seem that controversial, money talks and strong opposition from billionaires could stop a wealth tax in its tracks.
Another proposal, redistributing 20 per cent of public military spending to raise $260 billion (€246 billion), could also prove tricky in a world of growing geopolitical instability.
Could a billionaire tax help pay the climate finance bill?
In July, a meeting of G20 finance ministers in Rio agreed to a “dialogue on fair and progressive taxation, including of ultra-high-net-worth individuals”. Brazilian President Luiz Inacio Lula da Silva is hoping to progress talks on this potential billionaire tax at the G20 meeting this week.
The baseline proposal from the finance ministers of Brazil, Germany, Spain and South Africa earlier this year recommended a 2 per cent tax on roughly 3,000 individuals with a net worth of more than $1 billion (€946 million). This would raise around €230 billion a year to fight poverty, inequality – and the climate crisis.
It has broad public support in G20 nations with an Ipsos poll from June showing that 70 per cent of people back the idea that wealthy people should pay higher income tax rates. But as G20 leaders meet in Brazil this week, there are reports that negotiators from Argentina’s new right-wing government are trying to undo progress made on this agreement.
