Has the BBC been independent of any private or governmental influence about AGW?

The BBC has never been independent of private or governmental influence in just about anything. However, this is a particularly egregious conflict of interest.

Wow you guys are really starting to clutch at straws any company that employs many thousands of people and has a pension fund, is going to have investments in a wide range of different companies.

Funny the company your site mentions doesn't seem to be on the list there is everything from oil & tobacco to banking chemical even eBay & Walt Disney.

Maybe yes, maybe no. But it doesn't matter.

So far, that's overwhelmingly the global warming scientists.

"is this ethical?"

How would you know what "ethical" meant?
