Those plans include a thin-film solar factory, along with investments in wind and solar and in carbon-trading projects throughout the world. Most significantly, Masdar is pioneering a model carbon capture and sequestration (CCS) project with the energy and mining giants BP and Rio Tinto that will take CO2 emissions from industry in the emirate and store the CO2 in abandoned oil wells. Since even the most optimistic energy projections assume we'll be burning fossil fuels for decades, perfecting CCS is vital to controlling emissions--and who would be better suited to cleaning up fossil fuels than...
...really want to go green, the conventional thinking goes, buy a hybrid. Practically speaking though, there is a faster and cheaper option: shift to a low-carbon diet. The meal plan of the average American family accounts for 2.8 tons of CO2 emitted annually, compared with 2.2 tons for driving. Worldwide agriculture contributes some 30% of global greenhouse-gas emissions, far more than transportation. So when it comes to cutting your carbon footprint today, the truth is that what you eat is as important as what you drive. "If you can't buy a Prius," says Jonathan Kaplan...
...million tons in 2002--and the fertilizer used to grow that feed creates separate environmental problems, including surface runoff that leads to dead zones in coastal waters like the Gulf of Mexico. Those grain-fed cattle then belch methane, a greenhouse gas that is 20 times as potent as CO2. "Reducing beef is the first step to a green diet," says Michael Jacobson of the Center for Science in the Public Interest (CSPI...
That's one more reason why the world must work together to reduce global carbon emissions to minimize the impact of climate change. The trouble is, though, CO2 cuts won't be enough. As a recent paper in the Proceedings of the National Academy of Science points out, even if we are successful in cutting carbon emissions rapidly - hardly an easy task - the momentum of climate change will continue for centuries. That means our ability to adapt to the impacts of warming, including more aggressive responses to wildfires like those in Australia, will become all the more critical, lest natural...
...country of just 5.5 million people - about as big as a medium-sized city in China - but a fitting host of the climate change summit. Denmark has thrived while emphasizing clean energy and cutting carbon emissions - between 1980 and 2004, the country's GDP rose 56% while CO2 emissions dropped 35% - and thanks to smart policies and investment, more than a quarter of Denmark's electricity now comes from renewable sources. Danish companies also punch well above their weight in the growing wind turbine industry. To drum up global support for the summit, Hedegaard can easily make the case that...
