Quick quiz: Which country is the world's third-largest emitter of greenhouse gases, after the United States and China?
The answer, at least in recent years, has been Indonesia. That's surprising. It's not the world's third-largest economy. It's not an industrial powerhouse. But Indonesia has been clearing its vast rain forests of late, releasing huge stores of carbon into the air. One culprit has been the country's fast-growing production of palm oil, an edible vegetable oil that's increasingly being harvested to make biodiesel fuel for cars and trucks in Europe.
