Are the Conservatives losing their conviction on climate change?

This time a year ago Boris Johnson was preparing for the high-profile COP26 UN summit on climate change, hosted in Glasgow.

It wasn't a perfect gathering by any means, and Mr Johnson's own record on environmental issues was far from blemish-free, but real progress was made on coal, forests and national emission reduction goals.

The prime minister basked in the spotlight, glad-handing and cajoling, with then Prince Charles and his son William making speeches, charming world leaders and helping to position the UK as a leader on climate change.

Liz Truss's speech stopped by protest - Politics latest

Twelve months on and it's a very different picture.

The government is grappling with the intertwined energy and cost of living emergencies, and for many, the rosy glow of COP26 is fading fast.

In fact, it has been reported that our new prime minister asked our new king, famously passionate about protecting the environment, not to attend COP27 in Egypt next month, despite being invited.

Instead, Liz Truss appears set on beginning a new era of fossil fuels in the UK, lifting the moratorium on fracking for shale gas, and preparing to hand out around 100 new oil and gas licenses in the North Sea.

Campaigners are worried about what looks to be a loss of conviction on tackling climate change, and today two members of Greenpeace crashed her party conference speech, protesting against fracking among other things.

Ms Truss dismissed them as "part of the anti-growth coalition", to much applause.

This language is new, and it echoes the terms of a review, ordered by Ms Truss, into the UK's legally enshrined net zero carbon emissions by 2050 commitment.

The purpose of the review is to make sure that the policy is "pro-growth and pro-business" and to "scrutinise the green transition to make sure investment continues to boost economic growth and create jobs as well as increase energy security."

The man at the helm of the business department and therefore the clean energy transition and much of the government's climate change policy is Jacob Rees-Mogg.

Although like Ms Truss he has acknowledged the importance of renewable energy sources and nuclear power, Mr Rees-Mogg has previously warned of "climate alarmism" and remarked that he wants his constituents to have cheap energy, "rather more than I would like them to have windmills".

Ms Truss has publicly stated she is committed to net zero, but to many observers, there is a distinct slow down on the issue.

Perhaps, for a prime minister buffeted by problems, it is one crisis too many to deal with.

Campaigners will be deeply concerned that her government is starting to frame those who are driving a green agenda as anti-growth when her predecessor saw it as a great economic opportunity.
