The debate is not new; in fact most of the data and consequences were thoroughly described both in the IPCC reports (The United Nation workgroup: Intergovernmental Panel for Climate Change). Likewise, the report of the British Economist Sir Nicolas Stern, The Stern Report, pinpointed that the benefits of actions that cause climate change and the cost for the consequences are not directed to the same actors.
From an environmental and societal standpoint it is clear that both climate impact and food security have very high priority.
“The Clean Energy Scam” is revealed by Michael Grunwald in an extended article of the pacific issue of Time magazine:
The article blames massive subsidies for bio fuels in the US and in Europe for promoting less sound fuels and production methods. And, then carries on: But the basic problem with most biofuels is amazingly simple, given that researchers have ignored it until now: using land to grow fuel leads to the destruction of forests, wetlands and grasslands that store enormous amounts of carbon. He then continues: The biofuels boom, in short, is one that could haunt the planet for generations–and it’s only getting started.
World Bank Group Presiden Robert B. Zoellick, in a press conference the 10th of April, explained that bio fuels are contributing to the increase in price of wheat.
In the report:
the world bank seeks support for an international debate. They specifically highlight the need for balancing the need for food with need for production of bio fuel for abatement of climate change. The conclusion is that the second generation of bio fuels that can be produced from wastes and thus avoid use of primary farmland for food production, needs to be brought forward promptly.
Buses provide one of the most environmentally friendly mean of transports for people.
Again, BRT systems, biogas buses and the upcoming hybrid bus come out as winners, of the environmental performance.
