Ministerial appointments

Helgesen was first appointed minister for European affairs, a post he concurrently held while being chief of staff to the prime minister; from 2013 to 2015. On 16 December 2015, he was appointed minister of climate and the environment, a position he held until early 2018, when he was succeeded by Ola Elvestuen once the Liberal Party had entered government.

Minister of European Affairs

He became the first minister of European affairs on 16 October 2013, a newly created ministerial post in Solberg's Cabinet following the Conservative victory in the 2013 election.^[3]

A month into his tenure, he presented the government's strategy to keep Norway visible in the European Union. Helgesen also pledged that they would fight for Norwegian interests within the EU.^[4]

In October 2014, Helgesen expressed support for the EU's goal for new energy efficiency, but noted that it would succeed more if it also was free of charge. This came in response to criticism from the Liberal Party, who criticised the government for not taking enough action against reducing emissions of greenhouse gases.^[5]

In December, he praised the decision to digitalise the Three Wishes for Cinderella film from 1973, noting that digitalising old films was important. He stated: "Digitalising this film makes it available on new media platforms. The alternative would have been that it would eventually be forgotten".^[6]

In late April 2015, Helgesen expressed concerns about Hungarian prime minister Viktor Orbán's comments that the death penalty should be a relevant debate. Helgesen stated: "Hungary is a democracy, but it is sometimes difficult to see the democratic mindset of Orbán in his statements". He also expressed that any EU member state that goes against the union's values should expect counter reactions.^[7]

Minister of Climate and the Environment

In a cabinet reshuffle on 16 December 2015, he was appointed minister of climate and the environment.^[8]

Helgesen was among the guests invited to the state dinner hosted by U.S. President Barack Obama in May 2016, which was in honor of Solberg and other Nordic leaders Lars Løkke Rasmussen, Sauli Niinistö, Sigurður Ingi Jóhannsson and Stefan Löfven at the White House.^[9]
