The appointment of Greg Clark as a new Business, Energy and Industrial Strategy Secretary spells the end for a department which put climate change at the top of the agenda.
Just eight years after it was created by then prime minister Gordon Brown, the Department of Energy and Climate Change (Decc) is being merged into Mr Clark's new department and losing the "climate change" part of its name.
Environmentalists immediately reacted to the "shocking" news, voicing fears that the reshaping of departments showed the Government was downgrading climate change as a priority.

There were emotional scenes at the Paris climate talks as nearly 200 nations finally agreed a deal to attempt to keep temperature rises "well below" 2C.
That excitement was understandable given the historic deal has been 20 years in the making:

The US president has welcomed the Paris climate change agreement, saying it demonstrated "what's possible when the world stands as one".
Barack Obama emphasised the US role in the developments that led up to the Paris agreement, including the US role in the earlier 2009 Copenhagen talks, but said the Paris agreement had only been achieved because nations came together.
"Today the American people can be proud because this historic agreement is a tribute to American leadership. Over the past seven years, we've transformed the United States into the global leader in fighting climate change," Obama said.
He said the agreement was not perfect, but that it "establishes the enduring framework" to solve the climate crisis.
Barack Obama has said almost 200 countries "came together around the strong agreement the world needed" in agreeing a deal on climate change.
The US President said no agreement was perfect, including the Paris accord.
But he added that it was the best chance to save the planet.
Labour leader Jeremy Corbyn has welcomed the historic climate change deal agreed in Paris - and said he hopes it will prompt the government to reverse cuts to clean energy.
Accusing Prime Minister David Cameron of "taking us backwards on climate change action", Mr Corbyn said the challenge now was to turn the words of the agreement into action.
The Paris climate change agreement is historic in its ambition to take action against the worldwide threat of global warming. It represents a victory for the international movement for climate change action and global justice.
The challenge now is to turn the Paris agreement’s fine words into the strong action the planet and its people need.
The Labour Party will do everything we can to ensure Britain takes a leading role in making these aspirations a reality.
The Prime Minister has so far failed to show the leadership this agreement demands. In fact, the government has been taking us backwards on climate change action, including by cutting support for feed-in tariffs and the solar industry.
David Cameron must now take his cue from Paris, reverse his government’s cuts to clean energy and put real investment in the green jobs of the future.
