Sentences with phrase «global emissions reductions needed»

In particular, BECI can play a critical role in catalyzing the additional multidisciplinary academic work around carbon removal needed to address the growing scientific consensus (from institutions, such as the Intergovernmental Panel on Climate Change, the National Research Council, and the Global Carbon Project) that preventing further climate change likely requires carbon removal in addition to reductions in carbon emissions.

One of the fundamental questions in the global climate negotiations is: what level of «ambition», in terms of collective emission reductions, is needed to protect global climate?

The IPCC 2007 Fourth Assessment of climate change science concluded that large reductions in the emissions of greenhouse gases, principally CO2, are needed soon to slow the increase of atmospheric concentrations, and avoid reaching unacceptable levels.However, climate change is happening even faster than previously estimated; global CO2 emissions since 2000 have been higher than even the highest predictions, Arctic sea ice has been melting at rates much faster than predicted, and the rise in the sea level has become more rapid.

However, if high - emitting nations take the «equity» and «fairness» requirement seriously, they will need to not only reduce ghg emissions at very, very rapid rates, a conclusion that follows from the steepness of the remaining budget curves alone, but also they will have to reduce their ghg emissions much faster than poor developing nations and faster than the global reductions curves entailed only by the need to stay within a carbon budget.

If some consideration for historical responsibility is not taken into account in allocating national responsibility for ghg emissions reductions, then those poor nations which have done very little to create the current threat of climate change will be required to shoulder a greater burden of needed global ghg emissions obligations than would be required of them if responsibility for the existing problem is not taken into account.

They all accept the IEA estimate that to achieve a 50 % cut in global CO2 emissions by 2050 (widely believed to be equivalent to limiting the increase in global temperature to 2 °C), CCS will need to contribute nearly one - fifth of emissions reductions, across both power and industrial sectors.
