Berlin is going green: Climate Adaptation Act ensures millions of new trees!

Berlin is about to take a significant step towards a greener cityscape. Next Monday, a climate adaptation law is expected to be adopted in the House of Representatives, which takes up the initiative of the citizens' movement “BaumEntscheid”. With a collection of signatures of more than 33,000 votes, this put a lot of pressure on to initiate a referendum. But the Senate rejected this, but an amended bill was drawn up in collaboration with the initiators. Passage of the law is now imminent, necessitating the need for a special session in the House of Representatives to meet the legal deadline. According to the Uckermarkkurier the intention is to provide Berlin with over a million healthy trees by 2040.

There are currently around 440,000 urban trees registered in the capital, but the development is worrying: the numbers are declining and more than half of these trees are diseased. The planned law calls for planting a new tree on average every 15 meters on each side of the street. In addition, new trees will grow, especially in the lower strip between the road and the sidewalk, in order to improve the urban climate.

Funding and goals

Financially, the project is estimated to cost around 3.2 billion euros over a period of 15 years. This is a significant saving compared to previous estimates, which were over 7 billion euros. These savings are to be achieved through innovative planting methods and reducing bureaucracy. Financing options include the federal government's special funds and private donations for the tree planting.

A central goal of the law is also to cool the temperatures in 170 so-called “heat districts” by up to two degrees and to create “cooling islands”. In the future, binding heat action plans must be submitted by the Senate and the districts. In addition, an independent scientific control board with five experts will monitor the implementation of the law for the next five years. This could make Berlin a nationwide role model for other cities and municipalities.

Model for other cities

The proposed law has the potential to have an impact far beyond Berlin's borders. It could act as a blue ribbon for other cities that face similar challenges in dealing with urban infrastructure and climate issues. The measures to improve air quality and the urban climate through greener design not only have an environmentally friendly effect, but also offer an improved quality of life for citizens.

In today's fast-paced world, it is crucial to be active on platforms like X to stay up to date with such developments. There, users have the opportunity to follow current news, podcasts and live events and take part in stimulating discussions.

The upcoming resolution in the House of Representatives is a further step towards a more environmentally friendly future. Can the citizens who supported the referendum back then now hope for a greener city? At least it looks like the Climate Adaptation Act is laying a foundation that could encourage other cities to also take green initiatives.
