From smart grids in China to the carbon footprint of a French Bordeaux, we’ve got a summary of some of the latest cleantech headlines for you here:

• China producing more and more of the world’s carbon emissions? Don’t blame it — blame the countries that buy the stuff Chinese firms manufacture, as more than half of China’s emissions increases are due to product exports, according to the Centre for International Climate and Environmental Research;
• How to boost cellulosic ethanol production? Try shredding your feedstock first. A researcher at Purdue University says shredded corn stover yields higher production while also reducing energy input requirements;
• We don’t often get a chance to quote Wine Spectator, but here’s one that’s of interest to the cleantech crowd: the Bordeaux wine industry has announced plans to reduce its carbon emissions by 20 percent by 2020;
• The Cleantech Group reports that China’s State Grid Corporation plans to spend $36.5 billion (US) this year to upgrade its electricity distribution grid, which serves all but five provinces in the nation;
• Swiss car-maker Rinspeed plans to attend this year’s Geneva auto show to show off a car that’s not only solar powered but can adjust its shape according to the number of passengers inside, according to Inhabitat.
