Bloomberg to give $220M to end world smoking; New York City mayor wants to reduce tobacco use all over the world

Michael Bloomberg, the billionaire who has made reducing smoking one of his signature causes as mayor of New York City, is committing $220 million to his charity to go toward reducing tobacco use in countries that are home to millions of smokers.

He announced his four-year commitment to Bloomberg Philanthropies at the 15th World Conference on Tobacco or Health in Singapore on Thursday. The new commitment will bring the total amount he has directed to his eponymous charity to over $600 million for anti-smoking efforts since 2007.

"Tobacco kills every day, so we need to keep the fight moving forward and keep the momentum going," Bloomberg said in a statement.

Bloomberg, who made his fortune in the financial services industry, was ranked fifth on the Chronicle of Philanthropy's list of 50 of the "most generous donors" for 2011.

His new commitment will go toward initiatives including smoke-free laws, graphic pack warnings and raising taxes, charity officials said. The focus will be on country-level change, particularly in China, India, Indonesia, Russia and Bangladesh, which officials say account for the largest share of tobacco use in the world.

As mayor of New York City, Bloomberg has steered public health policy to ban smoking in restaurants, bars, parks and beaches; launch numerous advertising campaigns to alert consumers to the hazards of tobacco use; and raise the price of cigarettes through taxes.

James Colgrove, a professor at Columbia University's Mailman School of Public Health and author of "Epidemic City: The Politics of Public Health in New York," said there was a great deal of evidence supporting the tobacco reduction initiatives that Bloomberg Philanthropies and the city have pursued.

"Tobacco related illnesses is a huge global epidemic. It's one of the leading causes of preventable death," he said, adding that Bloomberg Philanthropies is one of a number of organizations that have committed to reducing tobacco use worldwide. "This is a priority for the entire public health and medical profession."

Tobacco is linked to the death of 6 million people worldwide each year, according to the World Health Organization. Most deaths are in low- and middle-income countries.
