(CNN) -- It was early in the morning when Luisa Neubauer got the call from her lawyer. She was staying at her mothers house, frantically trying to finish a book shed been working on, so she said it took her a moment to realize what had happened.
On April 29, the countrys Supreme Court announced that some provisions of the 2019 climate change act were unconstitutional and "incompatible with fundamental rights," because they lacked a detailed plan for reducing emissions and placed the burden for future climate action on young people.
The court ordered the government to come up with new provisions that "specify in greater detail how the reduction targets for greenhouse gas emissions" by the end of next year. The decision made headlines across the world.
"It was hard to digest, because it was so, so unexpected," Neubauer told CNN, stressing that while it was her name on the case -- Neubauer et al. versus Germany -- she was just one of many people involved.
"This case changes everything," she said. "Its not nice to have climate action, its our fundamental right that the government protects us from the climate crisis."
Peter Altmaier, the German minister for energy and the economy called the courts finding "significant" and a "historic decision for climate and the rights of young people."
