Greg Clark appointed UK minister for Business, Energy and Industrial Strategy

"I'd like to congratulate the Rt Hon Greg Clark MP, the new Secretary of State for Business, Energy and Industrial Strategy, and his cabinet colleagues on their appointments.

One big change she made was to scrap the Department for Energy and Climate Change - and unsurprisingly it hasn't gone down well.

Former energy secretary Ed Miliband branded the move "plain stupid".

The disappearance of DECC has sparked some concerns from industry and politicians, with Labour's Jonathan Hancock today suggesting that scrapping the department could be taken as a signal that the new government attaches less significance to the issues it dealt with. "Matters because departments shape priorities, shape outcomes".

Secretary of Stephen Devlin, Environmental Economist at the New Economics Foundation (NEF), described DECC's abolition as "a bad move by our new Prime Minister" that "signals a troubling de-prioritisation of climate change by this government".

Green Party MP Caroline Lucas described the decision as "deeply worrying".

"Turning to my committee and the crucial role we play in scrutinizing the government's energy and climate change policies, we are established under Standing Orders of the House of Commons", MacNeil said.

But Clark, like the defunct DECC's last cabinet secretary Amber Rudd, is a rare combination: a proud Conservative who is committed to the need to tackle climate change.

Thankfully, a number of already ingrained policy commitments will force the Government to take serious action on climate change.

"The UK will invest over £20 billion in wind energy in the next five years", Hugh McNeal, chief executive officer of RenewableUK, said in an e-mailed statement.

"This is shocking news".

"This week, the government's own advisors warned of ever-growing risks to our businesses, homes and food if we don't do more to cut fossil fuel pollution".

Brian Berry, Chief Executive of The Federation of Master Builders has responded to Theresa May's recent decision to axe the Department of Energy and Climate Change, stating that such a move further represents the governments continuing lack of interest in improving energy efficiency within construction.

And Stephen Devlin, an environmental economist at the New Economics Foundation (NEF), said the department's abolition was "a bad move by our new Prime Minister".

So if the reshuffle does mark a downgrade for climate change as a priority for the May administration, green activists have a lot to worry about.

"Tackling climate change is an era-defining challenge that must direct and determine what industries we develop, what transport infrastructure we construct, how we manage our land and what our diets look like". This requires a central coordinated strategy; if we leave it to the afterthoughts of various departments then we will fail.

"This week a stark official climate change risk assessment report was published: Leadsom must commit to action to protect the United Kingdom from worsening flooding and heatwaves".

"Over the coming weeks, I will speak to colleagues to explore how we can ensure that effective Parliamentary scrutiny on the crucial issues of energy and climate change continues". "Business will have a strong champion in government", he wrote.

During this period, he recognised the fantastic opportunities of the low-carbon economy transition, along with the emissions saving potential of technologies such as Carbon Capture and Storage and energy efficiency measures.

Officials told the Times that some DECC functions will be outright abolished while others will be handed back to the country's business department.
