Einen ungewöhnlichen Weihnachtsgruß erhielt EU Kommissionspräsident Barroso vor einer Woche von Kevin Anderson (Professor of Energy and Climate Change, Deputy Director of the Tyndall Centre for Climate Change Research): In dem Brief legt Anderson dar, warum das anvisierte Emissonreduktionsziel von 30 % bis 2030 überhaupt nicht kompatibel mit dem 2°C Ziel ist, und fordert 80% bis 2030:
According to the IPCC’s taxonomy of probabilities, both the language of international agreements and your statements as Commission President relate to a high probability of not exceeding 2°C: quantitatively between 1 and 10%. In stark contrast, the analysis informing much of the debate on the EU 2030 targets is premised on a 50% to 70% chance of exceeding 2°C. This misrepresentation of probabilities has dramatic consequences for the necessary scale of mitigation. For example, a 60% chance of exceeding 2°C has a carbon budget twice as large as that for a 10% chance. […] The EU must acknowledge this reality if it is ever to catalyse meaningful action on climate. This demands the courage to pursue an equitable and science-based 2030 decarbonisation target of around 80%. Anything less and the EU will renege on its 2°C commitments and, as the Commission rightly notes, bequeath to future generations a legacy of “devastating impacts”.
