The U.S. Environmental Protection Agency has announced significant plans to roll back environmental regulations, which includes eliminating greenhouse gas restrictions for coal and gas-fired power plants. Moreover, it aims to revoke the 2009 finding that highlighted the threats posed by carbon dioxide and other planet-heating gases to human health.
These rollbacks occur shortly after similar decisions were made by the European Union, Australia, and Canada, all of which have relaxed rules concerning emissions and environmental safeguards.
There’s a broad international scientific consensus that to limit global warming to 1.5 degrees Celsius, human carbon emissions must decrease by about 45% from 2010 levels by 2030. Unfortunately, current commitments from the international community fall short of achieving these targets outlined in the Paris Agreement.
Even with ambition retreats at the national level, cities are stepping up with bold climate actions, striving for transformative solutions. Across the globe, urban areas are increasingly working toward carbon neutrality, with some aiming even higher—seeking to actively remove carbon from the atmosphere to offset prior emissions.
For instance, New York City has pledged to cut greenhouse gas emissions by 80% over the next 25 years.
They are pursuing various innovative strategies, like offering resources for energy retrofits in large commercial and residential buildings, expanding low-carbon transportation options, and reducing emissions from food services. Additionally, the city has allocated over $20 billion to help neighborhoods adapt to climate threats like flooding and heat waves.
In Finland, Helsinki plans to achieve carbon neutrality by 2030, aiming for zero emissions by 2040, and becoming carbon-negative thereafter.
Efforts include managing the embodied carbon in buildings by imposing limits on emissions throughout the lifecycle of construction materials. Construction firms are working to adhere to these limits through diverse solutions, such as material changes and effective heating methods.
Additionally, Helsinki’s last coal-burning power plant is closing, which is expected to cut emissions by 30% in 2025 compared to 2024. One of the city’s notable projects involves creating large underground heat storage facilities to significantly reduce its carbon footprint.
Amsterdam in the Netherlands has its sights set on a 60% emissions reduction by 2030 and a staggering 95% by 2050.
The city’s Climate Neutral Program targets the elimination of fossil fuels, transitioning to clean energy sources like geothermal and solar. Authorities are also providing grants and loans to help residents move away from natural gas.
Vancouver, Canada, aims to reduce carbon pollution by 50% by 2030 and is proactive in adapting to climate change impacts.
Vancouver’s Climate Emergency Action Plan outlines steps regarding land use, transportation, and buildings to reduce carbon emissions from travel and buildings, with an ambitious goal to ensure most residents can easily walk, bike, or roll to their daily activities.
Sydney, Australia, has established three enduring business partnership programs to tackle emissions reductions in the office sector.
The Better Buildings Partnership collaborates with property owners who hold 55% of the office space, achieving a 95% reduction in emission intensity. Other initiatives support businesses in transitioning to renewable energy.
These cities are part of a coalition that aims for carbon neutrality through not just incremental improvements, but through significant changes to urban systems. The objective is to create replicable solutions and encourage other cities to expedite their carbon reduction efforts.
As these urban centers share their experiences and lessons learned, they equip each other to take action on climate change, demonstrating the critical role of cities—responsible for roughly 75% of global greenhouse gas emissions—within the broader climate framework.
The achievements of these cities may help counterbalance the challenges posed by less supportive national policies, ensuring that health and well-being remain priorities for all citizens.
