SHARM EL-SHEIKH, Egypt (AP) — At the UN climate summit in Egypt, leaders of developing nations have repeatedly said it’s not fair to expect them to cover the costs of rebuilding from devastating weather events in a warming world, plus invest in cleaner industry while they also pay much higher interest rates on loans than rich nations.

A plan put forward by Barbados Prime Minister Mia Mottley would overhaul the way much of development lending works. It is also giving voice to developing nations struggling under rising debt from climate damage.

“We were the ones whose blood, sweat, and tears financed the Industrial Revolution,” Mottley said in a scathing address. “Are we now to face double jeopardy by having to pay the cost as a result of those greenhouse gases from the Industrial Revolution?”

Debt has been growing in developing countries, sapping funds for education, health and clean energy. Much of the increase in debt in some Caribbean countries is related to extreme storms, Mottley said in a recent essay. The plan would make it easier for countries in the Caribbean, Latin America, Africa and Asia to get funds to beef up defenses against warming and put off debt payments when disasters strike.

Here’s a look at the Barbados plan, dubbed the Bridgetown Initiative for the island nation’s capital. Advocates say it could be a pathway to unlocking $1 trillion in climate financing.

The plan calls for special loan clauses that allow for suspending payments when a country is hit by a natural disaster or pandemic. That would immediately free up millions of dollars for governments to spend on relief and rebuilding. Barbados has been a pioneer in such clauses, last month issuing its first sovereign bond with a provision allowing for payments to creditors to be deferred for up to two years if the country experiences a “pre-defined natural disaster.”

The initiative includes a push to expand lending by international development banks such as the World Bank. The bank and its sister institution, the International Monetary Fund, were set up after the Second World War with the aim of financing reconstruction and reducing poverty. The power of rich countries such as the United States and Germany is built into the institutions.

But the World Bank in particular has been criticized for being too risk averse in lending. The Barbados plan would change risk ratings, crucially lowering interest rates.

Another idea is setting up a Climate Mitigation Trust backed by $500 billion worth of Special Drawing Rights, dues that member countries pay in to the IMF that can be drawn in times of crisis. Much of it is held by countries that don’t need it, said Avinash Persaud, Mottley’s special envoy for climate. The trust could be used to borrow a further $500 billion from the private sector that could be lent out at low rates for investment in big climate mitigation infrastructure projects. Up to $5 trillion in private financing could be unlocked this way, the plan’s architects say.

Other proposals include a levy on fossil fuel production or an international carbon border tax.
