developing nations

Developing nations are calling for richer countries to agree together on a fund that could add up to $1 trillion, using public and private money.

The move could allow richer countries to make up for some of their atmosphere-heating pollution by investing in clean energy projects or forests in developing nations.

Amid energy and economic crises, developed countries are expected to find billions extra in climate finance for developing nations.

It means that a global 'carbon market' can now been established, allowing richer nations to pay for projects in developing nations that reduce emissions and use this to meet their climate obligations.

Developing nations would like the new finance target to have sub goals where money is set aside for loss and damage and adapting to climate change - which historically has received a third of the funding of mitigation.
