Actions
Mamdani Campaign
In 2025, Third Act NYC advocated for the election of then-state Assemblyman Zohran Mamdani (D-Queens) for mayor of New York City. The group stated that it “enthusiastically endorses Mamdani” because he proposed enacting and enforcing left-of-center environmental legislation. Mamdani claimed he would strictly enforce decarbonization legislation that was already enacted in New York City, increase the amount of taxpayer dollars invested into solar and wind energy sources, renovate 500 public schools to run on wind and solar energy alone, and create 15,000 more unionized jobs in the weather-dependent energy industry. Third Act NYC stated that it would canvass for Mamdani and would work with the youth climate group Sunrise NYC on a get-out-the-vote campaign. 3
Climate Protests
In the summer of 2024, Third Act NYC coordinated with other climate groups in NYC to put on “Summer of Heat on Wall Street” climate protests. The protests intended to pressure Citi to stop investing in oil and gas production by disrupting operations at the bank’s headquarters. Third Act NYC considered the protests a success because it reached a claimed 5 million people on social media and Citi announced it would restrict the amount it would invest in Amazon rainforest-based oil and gas production. 4
Third Act NYC also stated that it would continue to pressure banks until they stopped investing in oil and gas production completely. 4
Sun Day Rally
On September 20, 2025, members of Third Act NYC joined the Sun Day Rally. The rally saw climate activists taking to the streets to advocate for an increase in investment of solar energy sources and an increase in taxes on individuals invested in oil and gas production. The protest was spearheaded by environmental activist Bill McKibben. The protest blamed the actions the Trump administration took when it rolled back federal grants for solar energy and put on hold wind farm projects claiming that these roll backs are “threatening not only the climate but also Americans’ pocketbooks.” 5
Williams-NESE Pipeline
Third Act NYC has publicly opposed the building of the Williams-NESE Pipeline in New York and New Jersey. 2 This pipeline would connect New York and New Jersey to a natural gas pipeline in Pennsylvania to help provide energy to New York City and the surrounding area. 6 Third Act NYC described the pipeline as “dangerous and unneeded,” and further stated that it “expects the [building] permit to be challenged in court.” 2
The Williams group, one of the companies working on the project, estimated that connecting to this natural gas pipeline would provide enough energy to power 2.3 million homes, create approximately 2000 jobs in the local area, and provide the state and local government with about $38 million in tax revenue. 7
Legislative Advocacy
Building Electrification
Third Act NYC has advocated for implementing Local Law 154 in New York City. 2 This law prohibits the use of oil and gas to produce heat or power appliances for all new construction and renovations in New York City and requires that all buildings be connected to the power grid and use electricity only. 8
Fund CLCPA
Third Act NYC has shown public support for funding the Climate Leadership and Community Protection Act (CLCPA). 2 The CLCPA would require the state of New York to achieve electricity production that emits no carbon emissions by 2040 and completely end the use of oil and gas as a means of producing power by 2050. Third Act NYC contends that funding this act and using exclusively weather-dependent energy sources like wind and solar will create more jobs for New Yorkers, save New Yorkers money on energy bills, and provide reliable electricity. 9
ASAP Act
Third Act NYC has shown public support for passing the Accelerate Solar for Affordable Power Act (ASAP Act). 2 If passed, this act would require New York to raise its solar production to 20 gigawatts by 2035 and to update the energy grid to work with new solar panels. Third Act NYC has voiced its support for this bill because it claims it could generate income for rural landowners and farmers when solar companies purchase their land to build solar farms, reduce carbon emissions, and create jobs in the solar energy sector. 10
