The Hangzhou Regulations on Building an Ecological Civilization Capital were unanimously adopted at the third plenary of the fifth session of the city's 14th People's Congress on May 25.

As China's first local legislation focused on constructing an ecological civilization capital, the law marks a historic step forward in the green governance for megacities.

The title "ecological civilization capital" was first granted to Hangzhou during the 2016 G20 Summit. Zhejiang University Professor Tou Xiaodong, who participated in the legislative review, said the law provides crucial legal backing for implementing the "lucid waters and lush mountains are invaluable assets" philosophy in large cities facing the dual pressures of growth and environmental protection.

Spanning 11 chapters and 92 articles, the regulation emphasizes actionable measures in areas such as green energy transition, low-carbon industries, and livable environments. Highlights include carbon footprint management, green industrial synergies, mandatory dust and noise control at construction sites, and a citywide "five-minute access to greenery" urban park plan.

The law was over a year in the making, incorporating more than 600 public suggestions. Its passage sets a precedent for balancing ecological and economic goals through legislation. Experts say it offers a replicable "Hangzhou model" for other major Chinese cities.
