History and Background of Climate Week NYC

Led by Climate Group's founders Steve Howard and Helen Clarkson, the international non-profit organization started Climate Week NYC in 2009 to promote climate action. Since it coincided with the UN General Assembly, this event turned New York City into a hub for environmental dialogue.

Climate Week NYC invited the world’s most influential leaders, civil society representatives, business icons, and the climate community to discuss climate change. Over time, the event became a significant fixture on the international climate calendar. Currently, it is the biggest global climate event, complete with an opening ceremony and event programs. 

The annual celebration includes in-person events like workshops and forums on sustainable development with international leaders. Moreover, given its scope, it has expanded beyond the wider Climate Week NYC context, with events spread across several major cities. 

In 2014, a climate march in NYC drew 400,000 participants, demonstrating the global concern about addressing climate change. That year’s Climate Week NYC also introduced initiatives like the influential RE100, which urged the world's most influential businesses to shift toward 100% renewable power. 

The event has also led to significant progress, including the historic Paris Agreement in 2015. In 2023, Climate Week NYC adopted the theme, “We Can. We Will,” reflecting determination and hope for positive action.

The Cause and Its Challenges

The observable increase in global temperatures and extreme weather events is a concrete reality that scientists have warned everyone about1. The analysis points to carbon emissions from transportation, industry, and energy production as the prime suspects. 

For example, transportation emissions alone account for nearly a third of the total emissions of the United States2. Moreover, despite increasing wind farms and solar panels, fossil fuels contribute 82% of the world’s energy3

Still, shifting to renewable energy is a plausible solution, though there are challenges. Proponents must overcome a lack of political support, the fossil fuel industry, and resource disparity among countries.  

Additionally, people must address the social impact of the climate crisis. Its adverse effects will harm the poor communities who live near polluting industries. They are firsthand witnesses to the consequences of climate change. 

Therefore, the fight is about climate justice, a fundamental principle of Climate Week NYC.

Why Climate Week NYC Matters

  • Humans burning fossil fuels like coal, oil, and gas has caused a severe environmental crisis. As these fuels burn, they release carbon dioxide into the atmosphere that traps heat, leading to global warming. 
  • Our forests absorb CO2, a primary greenhouse gas. However, we are also chopping down forests worldwide. As the forests disappear, their stock of CO2 goes back into the atmosphere, worsening the problem. 
  • Climate change is happening right now. The Earth is warming, ice caps are melting, and sea levels are rising. Those living in coastal communities stare down the prospect of losing their homes to the sea. 
  • Moreover, climate change has disrupted ecosystems and displaced animals worldwide due to changing temperatures and weather patterns. Some species might not adapt fast enough to these changes, which can drive them to total extinction. 
  • However, we can fight back by harnessing renewable energy, enhancing energy efficiency, protecting our forests, and practicing sustainable farming. But we need to act now.

Climate Week NYC is one of many efforts against climate change. Another is RE100, created by the Climate Group and CDP. These initiatives have secured commitments from companies like Apple and Google to use only renewable energy in their operations, setting an example for other global businesses. 

In New York City, OneNYC 2050 is a comprehensive plan that addresses climate change, equity, and democracy. The program includes initiatives such as renewable energy and community building. 

In another continent, the European Green Deal plans to make the entire continent climate-neutral by 2050. The EU is implementing policy reforms and investing in green energy to achieve this goal.
