How better technology can make city air cleaner and help save lives

During the dry season, Dhaka is one of the most polluted cities in the world. Air pollution levels during this period of the year reach 13-16 times higher than the international quality standard, and that outdoor air pollution kills 14,000of the city's residents annually.

The need to reduce air pollution in the capital may seem obvious. But using scarce resources to fight outdoor air pollution means less funding will be available from the national budget, international donors, or private citizens for other proposals that can do good.

China's impressive economic development has led to terrible outdoor air pollution. At the same time however, indoor air pollution has declined substantially, and fewer people now die from air pollution in China because of less poverty and access to modern energy.

Lomborg writes in China's biggest English-language publication China Daily (500k+ copies) that with increased wealth, China can afford to protect more nature and reduce pollution.

World leaders at the U.N. recently began a yearlong conversation about global goals for the next 15 years. Many will rightly talk about poverty, food, water and the environment. Few will mention energy. Yet we should.

Access to energy is one the most important drivers of development, e.g. improving living standards during the Industrial Revolution to more recently, helping lift 680 million Chinese out of poverty. Currently almost 3 billion people, mostly in Africa and South-east Asia, live without modern energy, instead using wood and dung as a source of fuel.
