Ocean acidification, ocean warming and sea Ocean acidification, ocean warming and sea level rise are also key concernslevel rise are also key concerns
Acidification of oceans due to CO2 is an additional recently highlighted reason for substantial GHG emission reductions.
A further increase in water temperatures, in combination with continuing acidification, will have major overall impacts on marine ecosystems and also on fisheries.

Complete disintegration of the Greenland Ice and the West Antarctic Ice Sheet would lead to +7 m and +5 m sea level rise (taking thousand or more years). A threshold for global temperature increase and the likelihood of these events are highly uncertain.

• EU Council target of limiting global temperature increase to +2°C above pre-industrial levels needs global emission reduction of 15% up to 50% by 2050 (from 1990 levels)
• Some global and European climate change is inevitable due to historical built up of greenhouse gases in the atmosphere, and time lags in climate and ocean systems
• EU Council recognised the need to prepare for and adapt to climate change in both developing and developed countries, to complement mitigation policies
• Addressing climate change has costs, but also brings benefits and opportunities e.g. for innovation

The EU target of max + 2 °C temperature increase requires at least stabilising at 550 ppm CO2–equivalent. Most likely a lower target is needed, e.g. 450 ppm. The latter would mean 80% emission reduction by 2050 for developed countries (from 1990 levels). However also other countries should limit increase or reduce emissions
The EU proposed that developed countries would reduce total GHG The EU proposed that developed countries would reduce total GHG emissions by 15-30% by 2020 and 60-80% by 2050 emissions by 15-30% by 2020 and 60-80% by 2050

• There is a substantial potential for energy savings and energy efficiency in all sectors (transport, industry, buildings)
• In power and heat generation a combination of low carbon energy technologies is needed, including substantial increases in all renewable energy technologies and high-efficient natural gas plants
• The use of carbon capture and storage (CCS) at a large scale may contribute, however further research and demonstration of the technology with manageable environmental and other risks is needed. Risks of CO2 storage in the ocean, i.e. in the water column and on the sea floor, are high
• Nuclear might also contribute. However there is still no acceptable long term waste storage available, some risks of accidental radioactive releases remain, risk of possible use for nuclear weapons, costs estimates differ, long preparation and building time

• Partnership to develop and demonstrate near zero emissions coal technology through carbon capture and storage
• Action Plans on clean coal technologies and energy efficiency & renewable energy

• More efforts are required to reach the modest Kyoto targets (which are only a first step)
• Substantial further reductions in global and EU GHG emissions are needed to avoid unacceptable impacts, hence strong global and EU action is needed in energy use and supply
• The challenges are enormous and all should contribute – governments, industries, private persons, researchers, NGOs, etc
