Push for Cleaner Stoves in Poor Countries to Cut Pollution

When famine strikes, governments and international donors step in with life-saving aid. And rich countries give more than $130 billion each year not only to feed the starving, but also to build crucial infrastructure and reduce gaps in access to education, health care, and clean water and sanitation worldwide.

All of this is vitally important. But one of the most powerful investments the development community could make is not in today’s problems, but in research that will address tomorrow’s challenges.

Reliable and affordable energy is vital for today's developing and emerging economies. Driven mostly by its fivefold increase in coal use, China's economy has grown 18-fold in the past 30 years and lifted 680 million people out of poverty. Worldwide, almost three billion people still don't have access to modern energy, instead they use firewood, dung and crop waste for cooking and heating indoors, which is so polluting, the World Health Organization estimates they kill one of every 13 people that die on the planet.

In Wall Street Journal, Matt Ridley asks how rich countries can best help poor ones and identifies five goals with great bang for the buck based on the output from Post-2015 Consensus so far.
