Find out these low- and no-cost ways to halt global warming

There are four key areas where the total potential for carbon reduction is highest between now and the end of the decade – solar and wind energy, reductions in deforestation, and restoration of forests and other ecosystems. Photo: AFP

Not only do we have the tools to slash emissions and curb global warming by 2030, but half of available carbon-cutting options are cost-free or very cheap, United Nations climate experts say.

There is no silver bullet, but a mosaic of actions – from ramping up solar and wind technology, to economy-wide energy efficiencies – were identified by the UN's Intergovernmental Panel on Climate Change (IPCC) as low hanging fruit.
