The study of inequality has been going on forever. To give you an idea, the index used to measure how unequal the distribution of income is -- the "Gini Coefficient" -- was invented a century ago. So, why the sudden interest? Why worry now about something that has been the fodder of academics, politicians, and the media for so long?
The world needs to put the brakes on climate change. But any plan to tackle climate change can't sacrifice economic growth if we hope to end extreme poverty, reduce inequality, and ensure that poor people gain access to energy. We need to decouple growth from carbon emissions. Here are five ways the world can shift to a low-carbon growth path.
The plunge in oil prices may be good for consumers and the global economy, but it could also hurt efforts to make our planet's energy system more sustainable. Policy makers from around the world can prevent this by taking advantage of cheaper oil to make meaningful changes in the way we price energy.
The costs to cities, coastlines and crops, as well as to the health and livelihoods of thousands, are mounting. China and the United States show the necessary determination to build a future based on low emissions through clean energy and livable cities because it makes sense for the environment and economies.
In order to successfully address climate change as a market failure, the oil and gas industry must internalize social and environmental costs involved with producing carbon dioxide -- not be given tax breaks and subsidies for continuing this economically inefficient and environmentally devastating behavior.
it's simply astonishing that Congress still is to renew the Production Tax Credit (PTC), one of the several tax incentives that invest in job creation in the clean energy industry. Just wind supports 80,000 jobs in the U.S., and 72 percent of the equipment needed to build wind turbines is manufactured in our country.
