Carbon? Why?

World 'needs radical cuts' on CO2

Renewable technologies could help arrest climate change
More carbon dioxide needs to be absorbed than emitted by 2050 in order to prevent catastrophic climate change.

That is the conclusion of a report by the Worldwatch Institute which urges bigger cuts in greenhouse emissions.

The authors say that even a rise in temperatures of 2 degrees C poses unacceptable risks to natural systems.
Global greenhouse gas emissions need to peak before 2020 and decrease drastically until 2050, the report says.

More CO2 will have to be absorbed than emitted in the second half of this century.

The report outlines 10 key challenges that must be adopted to avoid catastrophic climate change.

These include long-term planning, global co-operation and innovative solutions such as improved building design incorporating a variety of efficiency measures.

But they add that it is still possible to arrest and manage climate change with renewable technologies and more efficient ways of living.

But does there have to be emissions? What if there were no emissions to cut?
