Karácsony said no city can address the challenges of climate change alone and called on the government to create the regulatory and financial framework needed to support local action.

He said Budapest would then need to translate that framework into practice, while the private sector would have to implement it through investments and technology and residents would need to participate actively.

Karácsony said the government’s recently announced energy development plan, which includes a greater role for solar power, fits this approach.

He added that cooperation between Budapest and the government could create significant opportunities. The capital drew up a solar map several years ago and launched its Powered by the Sun program.

Karácsony said the previous government had prohibited new solar systems from feeding electricity into the grid, effectively preventing further installations.

Budapest’s goal is to install 10 mln sqm of solar panels across the city together with energy storage facilities, he said.

The program could save nearly 500,000 tonnes of carbon dioxide emissions and generate an amount of electricity equivalent to the total annual consumption of Budapest residents, Karácsony added.

“Now that the challenge is clear to everyone, and the Hungarian prime minister is finally speaking responsibly about the climate crisis, our plans – which seemed like mere pipe dreams just a few years ago – could quickly become a reality. But only if there is partnership,” the mayor said.
