Strong climate plans will boost economies: UN’s Stiell

New, robust national climate plans will act as an "economic springboard" for countries, Simon Stiell — executive secretary of UN climate body the UNFCCC — said this week.

"We are at the start of a race which will determine the biggest winners in a new clean energy economy," Stiell said at London's Chatham House on 10 April. "The next generation of national climate plans must be investment plans for sustainable and strong economies", he added. Cutting emissions and pollution from fossil fuel combustion "will mean better health and huge savings for governments and households", Stiell said. The 198 parties to the UNFCCC — comprised of 197 states and the EU — must submit new national climate plans, known as nationally determined contributions (NDCs), in 2025.

The plans must be in line with the 1.5°C temperature limit set by the Paris climate agreement and should "clearly articulate how finance is unlocked", Stiell said. He called for them to be submitted early next year.

But many countries will only be able to implement NDCs if there is "a quantum leap in climate finance this year", he warned. Finance will be "absolutely critical", at the UN Cop 29 climate summit, set for November in Baku, Azerbaijan, Stiell said.

Countries must decide on a new climate finance goal at Cop 29 — the next step from the $100bn/yr that developed countries agreed to deliver to developing nations in 2020-25. That deal should include more concessional finance, "new sources of international climate finance" and debt relief for the poorest and most vulnerable countries, Stiell said. He also called for the reform of multilateral development banks (MDBs) and "a financial system fit for the twenty-first century".

The World Bank and IMF should build on some steps already taken — such as the former's work on climate resilient debt clauses — and take more action, including revising capital requirements, Stiell said. The institutions meet next week in Washington.

The G7 and G20 groups of countries must also lead the charge, Stiell said. "G20 leadership must be at the core of the solution", particularly as the group's emissions equal around 80pc of global emissions, he added. Geopolitical challenges "cannot be an excuse for timidity, amidst this worsening crisis… Sidelining climate isn't a solution to a crisis that will decimate every G20 economy", he said.

The Cop climate summit is typically the UN's biggest event each year, but Stiell said that he would like to see "future Cops reduce in size". He is in discussions with a "very very active" Brazilian Cop 30 presidency around reducing the size of that Cop, set for November 2025 in Belem. He also noted agenda alignment across the three UN Cops this year — other than the climate-focussed Cop 29 in Baku, a biodiversity Cop and a desertification Cop will take place late this year, in Colombia and Saudi Arabia, respectively. Finance is "central to addressing all three", he said.
