The world's 48 poorest countries will need to find around $1 trillion between 2020 and 2030 to achieve their plans to tackle climate change — and those plans should be a priority for international funding, researchers said.
Estimates based on plans submitted by the least-developed countries (LDCs) toward a new U.N. deal to curb global warming show they will cost some $93 billion a year from 2020, when an agreement expected to be ironed out in Paris over the next two weeks is due to take effect.
That includes $53.8 billion annually to reduce emissions and $39.9 billion to deal with more extreme weather and rising seas, according to a report from the London-based International Institute for Environment and Development.
