The UN Conference on Sustainable Development starts today in Rio de Janeiro.

The meeting marks twenty years since the 1992 Earth Summit, when more than 108 heads of State agreed to work together to develop nation strategies to reduce carbon emissions, stabilise greenhouse gas, protect forests from destruction, and pay for their share of the damage caused to the earth through pollution.

Innovative sources of finance and resources from the private sector are key to achieving sustainable development in Africa, African leaders and world experts said yesterday at the United Nations Conference on Sustainable Development, or Rio+20, in Rio de Janeiro.
