Slechte berichtgeving massamedia
Brits klimaatrapport: we hebben nog een kansje
Stern Review on the Economics of Climate change
De Britse overheid heeft 30 oktober een rapport gepubliceerd van Sir Nicholas Stern, hoofd van de Government Economic Service en voormalig vooraanstaand World Bank econoom.
Hij concludeert zelf dat er nog tijd is de ergste gevolgen van klimaatverandering te voorkomen en dat nu actie ondernemen de economische schade in de toekomst enorm kan beperken. Dat kost slechts 1% van het bruto nationaal product en de economie kan blijven groeien.
De massamedia die het nieuws überhaupt melden, weigeren, zoals meestal, ook deze positieve kant van het nieuws te brengen en pakken vooral de sensationele, zwarte kant van het verhaal op:
We stevenen af op een crisis zoals in de jaren 30 van de vorige eeuw, het gaat ons 5 a 6000 miljard euro kosten, enorme hongersnoden komen er aan.
Inderdaad, als er niets gebeurt. Dat is misschien een realistisch uitgangspunt, maar zeer slechte journalistiek. Zoals steeds vaker zijn de massamedia geen deel van de oplossing, maar deel van het probleem, door essentiele informatie achter te houden en te kiezen voor de sensationele quotes. Kijkcijfers en oplagen boven verantwoordelijkheid.
Hieronder in ieder geval het persbericht zelf, meer op www.hm-treasury.gov.uk/newsroom_and_speeches/press/2006/press_stern_06.cfm

Publication of the Stern Review on the Economics of Climate change
The most comprehensive review ever carried out on the economics of climate change was published today.
The Review, which reports to the Prime Minister and Chancellor, was commissioned by the Chancellor in July last year. It has been carried out by Sir Nicholas Stern, Head of the Government Economic Service and former World Bank Chief Economist.
Sir Nicholas said today:
The conclusion of the Review is essentially optimistic. There is still time to avoid the worst impacts of climate change, if we act now and act internationally. Governments, businesses and individuals all need to work together to respond to the challenge. Strong, deliberate policy choices by governments are essential to motivate change.
But the task is urgent. Delaying action, even by a decade or two, will take us into dangerous territory. We must not let this window of opportunity close.
The first half of the Review focuses on the impacts and risks arising from uncontrolled climate change, and on the costs and opportunities associated with action to tackle it. A sound understanding of the economics of risk is critical here. The Review emphasises that economic models over timescales of centuries do not offer precise forecasts but they are an important way to illustrate the scale of effects we might see.
The Review finds that all countries will be affected by climate change, but it is the poorest countries that will suffer earliest and most. Unabated climate change risks raising average temperatures by over 5°C from pre-industrial levels. Such changes would transform the physical geography of our planet, as well as the human geography how and where we live our lives.
Adding up the costs of a narrow range of the effects, based on the assessment of the science carried out by the Intergovernmental Panel on Climate Change in 2001, the Review calculates that the dangers of unabated climate change would be equivalent to at least 5% of GDP each year.
The Review goes on to consider more recent scientific evidence (for example, of the risks that greenhouse gases will be released naturally as the permafrost melts), the economic effects on human life and the environment, and approaches to modelling that ensure the impacts that affect poor people are weighted appropriately. Taking these together, the Review estimates that the dangers could be equivalent to 20% of GDP or more.
In contrast, the costs of action to reduce greenhouse gas emissions to avoid the worst impacts of climate change can be limited to around 1% of global GDP each year. People would pay a little more for carbon-intensive goods, but our economies could continue to grow strongly.
If we take no action to control emissions, each tonne of CO2 that we emit now is causing damage worth at least $85 but these costs are not included when investors and consumers make decisions about how to spend their money. Emerging schemes that allow people to trade reductions in CO2 have demonstrated that there are many opportunities to cut emissions for less than $25 a tonne. In other words, reducing emissions will make us better off. According to one measure, the benefits over time of actions to shift the world onto a low-carbon path could be in the order of $2.5 trillion each year.
The shift to a low-carbon economy will also bring huge opportunities. Markets for low-carbon technologies will be worth at least $500bn, and perhaps much more, by 2050 if the world acts on the scale required.
Tackling climate change is the pro-growth strategy; ignoring it will ultimately undermine economic growth.
The Review looks at what this analysis means for the level of ambition of global action. It concludes that the levels of greenhouse gases in the atmosphere should be limited to somewhere within the range 450 - 550ppm CO2e (CO2 equivalent). Anything higher would substantially increase risks of very harmful impacts but would only reduce the expected costs of mitigation by comparatively little. Anything lower would impose very high adjustment costs in the near term and might not even be feasible, not least because of past delays in taking strong action.
The second half of the Review examines the national and international policy challenges of moving to a low-carbon global economy.
Climate change is the greatest market failure the world has seen. Three elements of policy are required for an effective response.
The first is carbon pricing, through taxation, emissions trading or regulation, so that people are faced with the full social costs of their actions. The aim should be to build a common global carbon price across countries and sectors.
The second is technology policy, to drive the development and deployment at scale of a range of low-carbon and high-efficiency products. And the third is action to remove barriers to energy efficiency, and to inform, educate and persuade individuals about what they can do to respond to climate change. Fostering a shared understanding of the nature of climate change, and its consequences, is critical in shaping behaviour, as well as in underpinning both national and international action.
Effective action requires a global policy response, guided by a common international understanding of the long-term goals for climate policy and strong frameworks for co-operation. Key elements of future international frameworks should include: Emissions trading
