...Airplanes operate on petroleum fuel, which means they release large amounts of carbon dioxide when they fly. Commercial air travel is currently responsible for a relatively tiny part of the global carbon footprint -just 3.5% of total greenhouse gas emissions, according to the Intergovernmental Panel on Climate Change. But the unique chemistry of high-altitude jet emissions may produce an additional warming effect, while the explosive growth in air travel makes it one of the fastest-growing sources of carbon gases in the atmosphere. And unlike energy or automobiles, where carbon-free or lower-carbon alternatives already exist, even...
...plastic sacks, some 88 billion of which are consumed each year in the U.S. alone, with many ending up stuck in trees, clogging roadside drains and killing the birds and sea creatures that accidentally ingest them. As legislators around the globe debate whether to tax or ban outright these petroleum-based products--which experts estimate take up to 1,000 years to decompose--celebrities have been doing their part to steer consumers down a greener path. This year's trendy eco-tote has been photographed on the arms of actresses Keira Knightley, Alicia Silverstone and Reese Witherspoon...
...minerals in Africa and elsewhere. Much of this has gone largely unnoticed. Chinese companies, for example, quietly invested $4.2 billion in Russian companies last year. But some, of course, has been decidedly noticed. The country's investments in Sudan, which increased in early July when China National Petroleum Corp. said it would spend an additional $25 million developing an offshore field there, have become a global flash point given the carnage the Khartoum government has allowed to continue in Darfur...

ExxonMobil's official mantra is that "we are doing all we can to bring more petroleum products to market to meet growing energy needs." The numbers say otherwise, and this is a company where numbers speak louder than words. The number that matters most is return on capital employed--that is, net profits divided by what's been invested in oil rigs, pipelines, refineries, etc. ExxonMobil's ratio, 32.2% last year, is consistently the industry's best. When ExxonMobil gives more money to shareholders than it spends on capital and exploration, that means its executives can't find enough...
