Mike Bloomberg's announcement to run for president didn't deliver full details of his platform, but his 12-year run as mayor and his philanthropy in political causes provide good clues. Here are some issues Bloomberg cares about and the industries they would affect. Tweet

Tobacco and e-cigarettes

Bloomberg Philanthropies has committed nearly $1 billion since 2007 to combat tobacco use worldwide. In September, the group said it is committing an additional $160 million to tackle vaping. The vaping industry had been viewed as a point of growth for tobacco giants like Japan Tobacco, British American Tobacco and Altria amid slowing cigarette sales. The desire to tap into that opportunity led Altria to take a $13 billion bet in vaping-market leader Juul in a deal announced last year. But Juul has come under its own pressure amid charges of marketing to teens with fruity flavors and other tactics. An outbreak of mysterious deaths relating to vaping has also put the company under scrutiny. Altria has already written down its investment in Juul by more than a third. In response to growing scrutiny, Juul has suspended the sale of all flavored products, aside from menthol. It remains unclear whether those flavors will be allowed to stay on the market. President Donald Trump said in September his administration was readying a ban on flavored e-cigarettes, but in a meeting with tobacco and e-cigarette executives, as well as public health groups last week, Trump raised concerns over the possible consequences of banning flavored e-cigarettes.

Energy

Bloomberg founded Beyond Carbon earlier this year, a $500 million group that advocates for energy reform. The group is in favor of renewable energy sources, like wind and solar, instead of coal power. It favors electric vehicles instead of those run by fossil fuels. The group has said it is "working to get the country on the path to a 100 percent clean energy economy," without giving a specific time frame for the goal. That pace is likely slower than the one demanded by Democratic hopeful Elizabeth Warren, who has said that as president she would sign an executive order putting a total moratorium on all new fossil fuel leases for drilling offshore and on public land. The long-term goal, therefore, may be tolerated by companies like London-based BP that have shifted their focus to net-zero carbon emissions in response to public pressure. Large oil and gas companies, including to varying degrees Royal Dutch Shell and France's Total, have acknowledged the threat of climate change, but are hoping to make the transition away from carbon steadily to preserve and deliver dividends. Others have been more reluctant. Bloomberg reportedly helped fund New York's lawsuit against Exxon through New York University's State Energy and Environmental Impact Center. The case accuses Exxon of misleading investors about its evaluation of climate change. Bloomberg's green focus is also likely to further pressure the coal industry, which is already suffering along with declining demand. At least seven coal companies have gone bankrupt this year, and dozens of coal plants have closed over the last few years.
