Germany’s Bundestag Votes to Cement 2045 Net Zero Goal in Constitution

The Bundestag, the lower house of Germany’s parliament, has agreed to enshrine reaching net zero carbon emissions by 2045 in the country’s constitution after a two-thirds majority voted in favor of spending reforms that mark a break with its longstanding fiscal conservatism.

The constitutional reform — approved on Tuesday by 513 of the Bundestag’s 733 parliamentarians — will allow the government to spend hundreds of billions of euros to fund defense, infrastructure and climate efforts.

The country’s constitutional ‘debt brake’ was established in 2009 and limited the federal government’s deficit to 0.35% of gross domestic product. Legislators from the center-right Christian Democratic Union (CDU) and the Christian Social Union (CSU) along with the center-left Social Democratic Party and the Greens approved the exemption of defense, infrastructure and climate spending from the rule in Tuesday’s session.

As part of the constitutional reforms, €100 billion euros will be allocated towards Germany’s Climate and Transformation Fund over the next 12 years to achieve the country’s climate targets for 2045. This is part of a wider €500 billion fund designated for infrastructure over the same time period.

The Bundesrat — a council of German federal states — is expected to approve the package on Friday, finalizing the legislative process.

Germany originally set out its 2045 goal in its Climate Change Act in 2021, which had the goals of reducing emissions by 65% by 2030 based on 1990 levels and 88% by 2040 before reaching climate neutrality by 2045.

Viviane Raddatz, climate director at conservation campaigner World Wildlife Fund Germany, said that the fund had great potential for boosting climate protection and that enshrining climate neutrality in the country’s constitution represented a milestone.

“But one thing is clear: €8 billion per year is far from enough to truly close the financing gap. Last week’s [government carbon] emissions data show that we urgently need to invest in the transport and building sectors: Germany needs €30 billion annually here alone — €18 billion for heat pumps and building renovation, €3.7 billion for heating networks and €12 billion for climate-friendly mobility, including €10 billion for rail,” Raddatz said.

Sebastian Manhart, a policy advisor at CarbonFuture, a startup focused on carbon removals technology, said in an online post that the constitutional amendment bucked the trends of countries like the US backtracking on their climate commitments.

“Instead, [Germany] has done the opposite: enshrined [its 2045 commitment] in the most visible and long-lasting way possible,” Manhart said.

Melina Maier, an associate at Global Counsel, an advisory firm, said that the 2045 target date “is a spending guideline, not a new binding target.” Maier explained that the country’s top court has previously ruled that the German constitution mandates a timely transition regardless of a specific deadline and that while the new constitutional amendment does reference 2045, “it does not have immediate legal implication for the approval of infrastructure projects.”

The 2045 date can, however, shape future legal debate on climate policies that entities like non-governmental organizations can use, Maier said.

Maier noted that around €8 billion a year will be allocated to the fund focusing on “energy-efficient buildings and low-emission industries”, but added that infrastructure and climate funds will not be sufficient to achieve decarbonization in Germany.

“It needs a coherent government strategy to align investments with priorities. The fund’s impact — both domestically and across the EU — will ultimately hinge on how the next government allocates and prioritizes investments,” Maier said.

The changes to the constitution come in the aftermath of German federal elections in late February when the conservative CDU, led by chancellor-in-waiting Friedrich Merz, and its CSU allies came out on top with a combined 28.6% of the vote, followed by the far-right party Alternative for Germany, which gained 20.8% of votes.
