Bjorn Lomborg runs the Copenhagen Consensus centre. Lomborg is hated by many environmentalists because he says that the return on spending on Global Warming is not very good, He's not a far left environmentalist.
The Copenhagen Consensus link you provided is specifically referring to indoor air pollution from cooking and heating homes with open fires.
I haven't explored the Lancet Commission's study enough to know how much they ascribe to indoor vs outdoor air pollution, but in my opinion, using the indoor figure in the same context as Global Warming or any kind of global pollution problem is extremely deceptive. You might as well just call all smoking-related deaths "caused by air pollution" because cigarettes were polluting the smoker's own air supply.
The wikipedia page has a figure of 5M
https://en.wikipedia.org/wiki/Air_pollution
The Copenhagen Consensus puts the figure at 7M
