This week marks 10 years since the People’s Climate March, then the largest climate march in history. Hundreds of thousands of people, led by Indigenous and environmental justice groups most impacted by climate change, marched in the streets of New York City on the eve of the UN Climate Summit. Joined by labor unions, faith groups, and activists of all ages, the march was a rallying cry to demand serious action in the face of a warming planet and the ultimate existential crisis.  Now, a decade later, New York has nation-leading models and mandates for cutting pollution and creating good, green jobs. But our energy bills are still too high. We don’t have accessible, clean transit options. Extreme heat, cold, and storms are threatening our safety and livelihoods. And at work, at school, and at home, we’re exposed to harmful pollution. We have less than five years left to prevent the worst climate impacts. Our state and city leaders must greenlight the investments we need for a safe and healthy New York before it’s too late.  After the 2014 march, New Yorkers came together. The statewide NY Renews coalition was formed laying the groundwork for an organizing network that would pass the Climate Leadership and Community Protection Act — setting a framework to transition New York off of fossil fuels and to fund a just transition to renewable wind and solar energy.  In New York City, ALIGN, the New York City Environmental Justice Alliance, and other partners formed the Climate Works for All coalition to tackle the city’s biggest polluters — buildings — with workers and impacted communities at the forefront.  At the state level, New York’s 2019 Climate Act requires New York to reduce economy-wide greenhouse gas emissions 40% by 2030 and 85% by 2050 from 1990 levels. Most importantly, this law requires that at least 35% of the investments go to disadvantaged communities — disproportionately Black, Brown, and low-income communities — living at the frontlines of pollution and disinvestment. However, state agencies are failing to implement the climate law, and missed deadlines are piling up. In New York City, we passed Local Law 97, promising to address dirty buildings, responsible for 70% of the city’s carbon pollution, by transitioning them off of fossil fuels and enforcing energy efficiency upgrades. But we’re set to miss our first target, and bogus legal challenges and attempted loopholes like Int. 772 waste precious city resources while the climate crisis marches forward.  The Climate Act and Local Law 97 are powerful mandates to transition the city and state from a fossil-fueled economy that worsens pollution, and produces more heat waves and extreme weather events while making billions for major corporations, toward a sustainable future with clean air, affordable energy, and good union jobs. But, without bold leadership from Gov. Hochul and Mayor Adams, these mandates risk failure. Low-income neighborhoods and communities of color are bearing the brunt of environmental pollution and heat islands, leading to rising rates of asthma, heart disease, and stroke. The impacts of the climate crisis have never been so apparent; nationwide, the public wants action on climate to protect future generations. But it can and will get worse if we don’t take action in the present.  So what can we do? Hochul can sign the Climate Superfund Act to make polluters pay for the damage they have profited off of and fund climate action and resiliency. She can also direct agencies to fully implement the Climate Act and ensure that the coming emissions cap-and-trade program will raise enough to fund community-led climate justice projects across the state. In NYC, Adams can defend Local Law 97, incentivize and enforce green energy upgrades for private buildings, and fund them for public ones, starting with schools in frontline communities. But New York will need much more investment and urgency from our elected leaders to slow the worst effects of the climate crisis and build the just, resilient, clean-energy future our communities deserve. Ten years after the People’s Climate March, the public understands the scope of the crisis at hand. We won’t stop fighting for climate justice — now it’s time for our leaders to act.  Edel is the executive director of NY Renews, a coalition of 380-plus environmental justice, faith, labor, and community groups behind the nation’s most progressive climate law.
