BERLIN (Reuters) – Europe and the United States should join forces in the fight against climate change and agree on a new framework for the digital market, limiting the power of big tech companies, European Union chief executive Ursula von der Leyen said.

“I am sure: A shared transatlantic commitment to a net-zero emissions pathway by 2050 would make climate neutrality a new global benchmark,” the president of the European Commission said in a speech at the virtual Munich Security Conference on Friday.

“Together, we could create a digital economy rulebook that is valid worldwide: a set of rules based on our values, human rights and pluralism, inclusion and the protection of privacy.”

The EU has pledged to cut its net greenhouse gas emissions to zero by 2050, while President Joe Biden has committed the United States to become a “net zero economy” by 2050.

Scientists say the world must reach net zero emissions by 2050 to limit global temperature increases to 1.5 degrees above pre-industrial times and avert the most catastrophic impacts of climate change.

The hope is that a transatlantic alliance could help persuade large emitters who have yet to commit to this timeline – including China, which is aiming for carbon neutrality by 2060, and India.

“The United States is our natural partner for global leadership on climate change,” von der Leyen said.

She called the Jan. 6 storming of the U.S. Capitol a turning point for the discussion on the impact social media has on democracies.

“Of course, imposing democratic limits on the uncontrolled power of big tech companies alone will not stop political violence,” von der Leyen said. “But it is an important step.”

She was referring to a draft set of rules unveiled in December which aims to rein in tech companies that control troves of data and online platforms relied on by thousands of companies and millions of Europeans for work and social interactions.

They show the European Commission’s frustration with its antitrust cases against the tech giants, notably Alphabet Inc’s Google, which critics say have not addressed the problem.

But they also risk inflaming tensions with Washington, already irked by Brussels’ attempts to tax U.S. tech firms more.

Von der Leyen said Facebook’s decision on a news blackout on Thursday in response to a forthcoming Australian law requiring it and Google to share revenue from news underscored the importance of a global approach to dealing with tech giants.
