...cork as a naturally sustainable product will turn consumers onto the fact that buying their bottle of wine for dinner could leave a positive environmental footprint. Along with the WWF and companies like Willamette Valley Vineyards, Amorim actively promotes the cork industry's green merits - its contribution to carbon dioxide sequestration, preserving biodiversity and combating desertification. "Can you contribute to a better world and a better wine? If the answer is yes, then what is there to discuss?" De Jesus says...
...Airplane manufacturers and airlines are working on ways to cut carbon emissions by raising fuel efficiency - building lighter and more aerodynamic planes, towing jets on the ground, and improving engine capacity. Designers are looking at running planes on biofuel, and Virgin Atlantic head Richard Branson has promised to build a biofueled jet by next year. But industry experts believe such incremental changes could improve efficiency by 1% or 2% a year at most, while passenger miles are set to grow at 5% to 6% annually. "We're left with a sustainability gap," says Roger Gardner, chief executive of OMEGA...
...Even as carbon emissions from air travel grow rapidly, scientists are investigating claims that they may double the warming effect because of the altitude at which they're emitted. As jets soar they leave behind contrails, vapor threads of condensation that can persist for hours, especially in colder areas, and behave like high-altitude cirrus clouds. Those clouds seem to have a net warming effect, trapping heat in the atmosphere. Planes also create ozone, a greenhouse gas that has a stronger warming effect at high altitudes than low. The science is still being nailed down, but the side effects...
...Though there's no technological silver bullet, there are policy options available to manage air travel emissions such as carbon cap and trade schemes. But those won't be simple: Air travel was left out of the Kyoto Protocol on curbing emissions in part due to the complexity of assigning national responsibility for gases spewed by international flights. Just getting governments to share air space more freely, which would allow planes to fly more direct routes and cut fuel consumption, has proven to be an ongoing headache...
...those well-off on a global scale (anyone who can afford a JetBlue ticket) to stop flying in order to save the poor from the effects of climate change. It's not quite that simple, but until technology and policy catch up - which still seems a long way off - carbon emissions will only slow if consumers choose to use less energy, live more modestly, and fly less. In other words, stay at home to save the world...
