Royal Dutch Shell has been accused of pursuing a strategy that would lead to potentially catastrophic climate change after an internal document acknowledged a global temperature rise of 4C, twice the level considered safe for the planet. A paper used for guiding future business planning at the Anglo-Dutch multinational assumes that carbon dioxide emissions will fail to limit temperature increases to 2C, the internationally agreed threshold to prevent widespread flooding, famine and desertification. Instead, the New Lens Scenarios document refers to a forecast by the independent International Energy Agency (IEA) that points to a temperature rise of up to 4C in the short term, rising later to 6C. Louise Rouse, an investor relations specialist and consultant to Greenpeace, said the New Lens document undermined Shells claim that ongoing oil and gas exploration helps raise living standards in the developing world by supplying the energy for rapidly expanding economies. There is an incoherence at best between oil companies on the one hand positioning themselves as being on the side of the worlds developing countries and while on the other actively pursuing strategies which will entail catastrophic climate change which we already know is having a significant impact on the global south, she said. Shells carbon dioxide emissions have risen in 2014 and are set to increase further as it expands the business through a planned 47bn takeover of rival BG.
