Taking stock of the implementation gap in climate policy

A gap persists between the emissions reductions pledged by countries under the Paris Agreement and those resulting from their domestic policies. We argue that this gap in fact contains two parts: one in the policies that countries adopt, and the other in the outcomes that those policies achieve.

What Is A Whale?
Whales are marine mammals belonging to the group Cetacea, which also includes dolphins and porpoises. Whales are known for their large size, with many whale species weighing several tonnes.
Although descended from land animals, whales are fully adapted to aquatic life, possessing streamlined bodies for efficient swimming, flippers for maneuvering, and a paddle-like tail, known as a fluke, for propulsion.
Despite living in the ocean, whales are air-breathing animals and therefore have to surface periodically in order to breathe via a blowhole on …

For the first time in a century, the US is raising fees for drilling on federal lands
The rules for oil and gas extraction on public lands have been stagnant for decades. Oil and gas companies have paid 12.5 percent in royalties to the federal government for drilling on public lands for more than a century, significantly lower than the rates many Western states charge. Companies must also post bonds, financial instruments that guarantee taxpayers aren’t left holding the bag for environmental cleanup if a driller goes bankrupt. But those bonds were set in 1960 at $ 10,000 per lease, a small fraction of the true cost of plugging and cleaning up oil wells that businesses leave behind.
Good governance groups and environmentalists have long argued that these rules have functioned as a subsidy for fossil fuels, shortchanging taxpayers and encouraging oil and gas extraction at a time when the planet is warming at a dangerous rate. …
