Sentences with phrase «fifth of the global carbon emissions»

Not exact matches

Researchers estimate that if all human - related deforestation of the tropics were to stop, the forests could absorb more carbon than at present, equivalent to one - fifth of global emissions.

The emission limit depends on climate sensitivity, but central estimates [12]--[13], including those in the upcoming Fifth Assessment of the Intergovernmental Panel on Climate Change [14], are that a 2 °C global warming limit implies a cumulative carbon emissions limit of the order of 1000 GtC.

Rather, conserving Amazonian forests both reduces the carbon dioxide flux from deforestation, which contributes up to a fifth of global emissions, and also increases the resilience of the forest to climate change.

The Fifth Assessment Report from the Intergovernmental Panel on Climate Change (IPCC)-- the world's leading climate science body — projected a number of scenarios, each plotting amounts of carbon emissions and the resulting future global average temperatures.

A fifth of global human - caused carbon emissions today are absorbed by terrestrial ecosystems; this important carbon sink operates largely without human intervention, but could be increased through a concerted effort to reduce forest loss and to restore damaged ecosystems, which also co-benefits the conservation of biodiversity.

The emission limit depends on climate sensitivity, but central estimates [12]--[13], including those in the upcoming Fifth Assessment of the Intergovernmental Panel on Climate Change [14], are that a 2 °C global warming limit implies a cumulative carbon emissions limit of the order of 1000 GtC.

It also accounts for about half of global diesel use, a third of all transport - related carbon emissions and a fifth of NOx emissions, a key air pollutant.

This is equivalent to approximately six billion tonnes of carbon dioxide being released into the atmosphere, contributing up to one - fifth of global greenhouse gas emissions.
