This is the Guardian.

Today, a Guardian investigation reveals the energy companies

betting billions of dollars the government's aren't serious about climate change

and won't force them to keep gas and oil in the ground.

Damien Carrington, you're the Guardian's environment editor

and I want you to take me back to the UN Climate Summit in Glasgow.

In November last year, when world leaders met to hash out the details of a new agreement,

on a pact that was supposed to steer us away from this climate disaster we're headed towards.

It was very intense at the end.

India wishes to take the floor.

India, you have the floor.

You know, people have sleep deprived and stressed and wondering what's going to happen.

And so we were sat there as they tried to get this sort of final agreement over the line.

There'd been this big rower back coal and so for the first time in 25 years of UN negotiations,

they'd actually got a mention of coal and the initial mention was to phase out coal.

But there'd been all sorts of eruptions behind the scene, led by India, but China

never involved as well and they'd water that down to phase down.

Including escalating effort to face down.

Unabited coal power.

And there was this moment when the president of the conference,

Alex Sharma, government minister from the UK basically almost cried.

I also understand the deep disappointment.
