Amy Larkin

Amy Larkin lived in Tarrytown before moving to Cortland Manor. She is an award-winning  entrepreneur, activist, and  producer who has been at the forefront of the environmental movement for decades.  Her 2013 book, Environmental Debt: The Hidden Costs of a Changing Global Economy revealed the links between our environmental and financial crises -  both causes and solutions.   From 2014-16, she served as Vice Chair of the World Economic Forum’s Global Agenda Council on Climate Change.


In 2019, Amy co-founded PR3, a public-private partnership forging systemic solutions that dramatically reduce plastic production and consumption.  When globally deployed, the move away from single use packaging can reduce the manufacturing of plastic packaging by 90% and cut associated emissions by 80%. (Packaging uses ~40% of all plastic production).  ­Reuse is a solution commensurate with the gravity of both the plastic and climate crises. 


While Greenpeace Solutions Director, Amy led the collaboration with the Consumer Goods Forum, a consortium of 400 multinationals to eliminate HFCs.  The industry’s commitment directly led to HFCs’ inclusion in the Montreal Protocol in 2016, anticipated to save .5°C degree of global warming. This work won the prestigious 2011 Roy Award from Harvard’s Kennedy School of Government.

Amy has spoken around the world on Climate Change and its relationship to Money, Culture, and Spirituality, including at the 92nd St. Y’s 2019 Yom Kippur Kol Nidre service.  She wrote regularly for The Guardian from 2012-2015.  

Topic: Climate Solutions:  It takes a village...and a lot of courage.

There is no replacement for courage...Right now, we are looking on with a mix of disbelief and ennui as extreme weather engulfs us. In some cases, we are trying to take what appear to be reasonable steps, mostly in order to protect our precarious perch in the world's economy. The trouble is, the time for "reasonable" has passed. We have somehow forgotten that if there is no nature, there is no business. We are in a global environmental emergency, but we are behaving as if incremental improvements to "business as usual" will do. 

This courage must be expressed with and within our local villages and our global village.  

I'll share my current work with PR3 drafting standards to create reusable packaging systems, a significant plastic and climate solution. We are working with multinationals, entrepreneurs, packaging producers, environmental justice activists, scientists, urban planners, and numerous government departments in cities, nations, and the Global Plastic Treaty currently being negotiated.  This diverse village of brave souls and institutions is going to lead the world away from single-use packaging to serve people, planet and profit.

Cynthia Scharf

Cynthia Scharf is a Tarrytown resident. Since 2017, she has served as the Senior Strategy Director at the Carnegie Climate Governance Initiative (C2G) and is a recognized international specialist on climate geoengineering policy. 

Scharf previously served as the head of strategic communications and chief speechwriter on climate change for the United Nations Secretary-General from 2009-2016. As a senior member of the Secretary-General’s Climate Change Support Team, she played a key role in organizing the Secretary-General’s two global climate change summits (2014 and 2009) and closely supportedthe Secretary-General during the UNFCCC negotiations, including the landmark Paris climate change agreement in 2015.

Prior to her work on climate change, Scharf worked on global humanitarian and public health emergencies at the UN and with international non-governmental organizations in the Balkans, Africa, the UK, and Russia. She also has private sector experience working in the social impact investing field. Scharf began her career as a journalist in Moscow in the early 1990s covering the collapse of the communist system in the former USSR and Eastern Europe.

Scharf’s articles on politics, the economy, and the environment have been published in The International Herald Tribune, The Wall Street Journal Europe, Los Angeles Times, Christian Science Monitor, Moscow Times, Globe and Mail, and elsewhere. She received her MA from Georgetown University’s School of Foreign Service and speaks Russian.


Despite welcome advances on renewables and a public increasingly concerned about climate change, the planet continues to heat up. Researchers are exploring what additional tools might help reduce carbon concentration in the atmosphere and quickly lower the global thermostat. Many see the latter approach as akin to opening a Pandora’s box to a whole new set of risks. What’s the state of research and rules around these new approaches, and what might be next? 

Past Events

Spring clean-up on the Old Croton Aquaduct

On a gorgeous Saturday morning in mid-March, 35 volunteers, including many children and teens, gathered to learn about native and non-native flora and fauna. 


The event was organized by the Irvington Green Policy Task Force in collaboration with the Friends of the Old Croton Aqueduct, the NYS Office of Parks, Recreation and Historic Preservation, the Irvington Parks Department, the O’Hara Nature Center and the Pollinator Pathways Project. 


Led by the Friends of the Old Croton Aqueduct Horticulturist Peter Strom, and the Irvington Green Policy Task Force volunteers Jasena Sareil, Leola Specht, and Lisa Antonelli, the volunteers split into their chosen groups: non-native invasives and Spotted lanternflies egg masses identification and removal; expansion of community pollinator garden; and litter collection/removal.  


The event helped create awareness of the benefits of non-native invasives removal and planting of natives to regenerate biodiversity and provided the community with a wonderful hands-on experience. 


The Irvington GPTF is planning to organize with their partners two additional similar community events on the OCA later this year (spring and fall) to further help educate the community about the native plants contribution to the local ecosystem and sustainability.  


The goal is to restore the OCA areas where the non-native invasives were removed in favor of native plants including small trees and shrubs suitable for the location to minimize soil erosion and support pollinators. 


We are taking a great deal of action on protecting, preserving, and restoring Irvington’s portion (almost 2 miles!) of the Old Croton Aqueduct State Park!

December 6: Eugene Linden

Topic: How It All Went Wrong on Climate Change

Eugene Linden writes about the environment, nature, animal behavior, finance and social issues. He has been writing about climate change since 1988, in articles, essays and op-eds, for Time, The New York Times, and many other publications. His previous book on climate, The Winds of Change: Climate, Weather, and the Destruction of Civilizations, was awarded the Grantham Prize Special Award of Merit. He has published ten other books, which have appeared in 13 foreign language editions.

Highlights from the talk: 

Known as Professional Killjoy, Linden has been writing about the climate since 1988 and says, like COVID, people will "deny it to their death." In addition to the greenhouse effect, we have the "Whitehouse Effect," or the "Lobbyist Effect" starting with H.W. Bush who had a conference on climate change where participants couldn't mention global warming. Now we are perilously close to pushing the system into an unstoppable feedback loop. Linden conveys the story of climate through four clocks: reality, science, the public and business and finance. Perverse business and finance incentives have rendered us blind. If we do not wean ourselves from fossil fuels, the climate may wean us from our food supply. But when we set ourselves  we can create a vaccine in 9 months instead of 7 years. Ending on a positive note, Linden touted the potential of deep geothermal provide the most economic source of power on our planet, and be retrofit to coal plants. See his article in New Scientist here.

Guest Speaker - Seth Godin

Highlights from the Talk

Are two greatest problem are



Seth described how oil companies created the concept of a carbon footprint – that each individual must get to zero footprint before they can take on anything else, which is an impossibility in the current oil-based economy that stops too many of us from taking action.  So don't get hung up on being perfect. It is more important to focus on organizing and building the movement for systems change. See our Instagram for a video clip.

October 4

Guest Speaker - John Nolon

Distinguished Professor of Law Emeritus. Co-Counsel, Land Use Law Center, Pace University. Tarrytown resident. Supervises student research and publications regarding land use, sustainable development, climate change, housing insecurity, racial inequity, and the coronavirus pandemic. He is Co-counsel to the Law School's Land Use Law Center, which he founded in 1993. He served as Adjunct Professor of land use law and policy at the Yale School of the Environment from 2001-2016. Before he joined the law school faculty, he founded and directed the Housing Action Counsel to foster the development of affordable housing.

Topic: Climate Change and the Mysterious Power of Local Land Use Law

The Intergovernmental Panel on Climate Change (IPCC) produces comprehensive climate reports.[1] Formed in 1988, it consists of 195 national governments and is assisted by hundreds of scientists and other experts.[2] These advisors review thousands of climate science research reports contributed by the global scientific community. The IPCC’s research and solutions at the global, national, and local levels enjoy significant respect.  If there is a single entity whose escalating warnings about the climate catastrophes ahead and formulation of solutions that can be trusted, it is the IPCC.


In February of 2022, the IPCC promulgated Climate Resilient Development (CRD) as a principal strategy for managing climate change.[3]  CRD, it states, combines adaptation and mitigation strategies to achieve sustainable development for all. A careful reading of its recent report reveals that local governments, wielding their land use regulatory authority, have been delegated a major role in managing climate change.  The IPCC identified local land use strategies as effective tools for implementing CRD.[4] The effects of climate change are intrinsically local; planning and action at the ground level are required. 


Local governments can adopt, enforce, and incentivize CRD strategies to control and shape land use through regulation, capital spending, and policy.  CRD components can be found in comprehensive land use planning. CRD is implemented by strategies that ensure low carbon building, reduce car dependency through decarbonized transportation, and foster green infrastructure and carbon sequestration. Additionally, cities provide increased job and housing availability through in-fill and adaptive reuse, taking pressure off greenfields for future development. Climate-related disasters can be anticipated and managed by hazard mitigation planning and execution. Strategies that incorporate resilient adaptation to sea level rise and inland flooding can minimize the impacts of climate hazards. To achieve sustainable development for all, local governments can incorporate equity and justice in these strategies.

For part of this summer he could be found in the Hermits Wetland of Irvington Woods battling invasive Phragmites.

Topic: Climate Change from Global Scales to Irvington Village

Every day we see more headlines about heat waves, forest fires, and flooding. What is going on and what should we be worried about in Irvington? The fundamental physics of climate change are well understood but some of the details are not. The talk will start off discussing what is happening at the global scale, discuss some of the weather this summer, and then look at the impacts of climate change on Irvington.

Irvington Green Monthly Meetup: July 19

Subject: The increased presence of the invasive Spotted Lanternfly, its negative impact on the local ecosystem and ways to tackle the issue

Location: The Irvington Public Library

Click to expand for minutes from the meeting

Participants:   Charlotte Binns, Jasena Sareil,  Anne-Jaffee Holmes, CJ Reilly, Rosemarie Gatzek, Joan Nenimmo, Maria Ralescu, Jeannie Elder, Laurie Friedman, Kathleen Baca, Lauren Glattly, Adrian Price=Whelan, Renee Shamosh, Melanie Solomon, Bill Estes, Sachin Hardas, Lori Fettner, Damian Chadwick                          

The meeting was held to discuss the increased presence of the Spotted Lanternfly (SLF) in Irvington and to educate residents on the SLF’s negative impact and effective ways to remove them without the use of chemicals.

Jasena Sareil explained that the GPTF has been receiving numerous reports on the sighting of Spotted Lanternfly nymphs. SFL is an invasive pest from Asia that primarily feeds on Tree-of-heaven (Ailanthus altissima) but can also feed on a wide variety of plants such as grapevines, hops, red and silver maple, walnut, sycamore, birch, Tulip tree, fruit trees and others. This insect negatively impacts New York's forests as well as the agricultural and tourism industries. SLF's feeding (sucking on sap) damage stresses plants which can decrease their health and in some cases cause death. As SLF feeds, the insect excretes honeydew (a sugary substance) which can attract bees, wasps, and other insects. The honeydew also builds up and promotes the growth for sooty mold (fungi), which can cover the plant, forest understories, patio furniture, cars, and anything else found below SLF feeding.

NYS is asking its residents to kill the nymphs, adults, and egg masses when spotted.  

In Irvington, we have mostly noticed them on the invasive non-native Tree-of-heaven and Porcelain berry, however, they can be also found on Black walnut, Silver maple, Sycamore, rose bushes etc.

Residents were encouraged to help remove SLFs without the use of chemicals as follows:

1. Squish them by clapping your hands together (gardening gloves help). Approach them from the back if possible. They get tired after about 3 jumps and pause for about 2 seconds so are easier to catch.

2. Step on them.

3. On thorny plants such as rose bushes, hose them down with a strong water pressure and squish / stomp them after they wash off.

4. Use a vacuum, just disconnect the plastic part for carpet/floor so that you can suck them in. If it is a larger trunk of a tree, they will start hiding on the other side so you will need to squish those with your hands. Once done, please put the vacuum bag in a zip lock bag and place it in the trash. Jasena Sareil brought a special vacuum that was provided to the GPTF by the Lower Hudson PRISM.

5. Plat milkweed, which is a crucial plant for the survival of monarch butterflies, but SLF die after digesting its sap.

6. Trap them – Traps can be purchased or made at home. Please also avoid using glue traps as they also kill beneficial insects as well as birds.

What we do not recommend: Unlike some other resources, we DO NOT RECOMMEND the use of any chemicals even a dish soap or vinegar solution as they negatively impact other wildlife. Birds / spiders are learning to eat SLFs and if they ingest them with these solutions on, they will die or get sick.

There is no need to panic. We will get a chance to remove Spotted lanternfly egg masses after they are laid in the late summer and into the early winter, with the majority of egg mass deposition occurring in October. These egg masses survive winter and hatch into SLF nymphs in the spring. These egg masses are the only stationary stage of the SLF, making them an easy target for removal. We will provide educational materials on how to remove egg masses once we start noticing them.

The need for professional removal of Trees-of-heaven was discussed as one of the major ways to address this issue with a special focus on the Old Croton Aqueduct where there is major infestation of TOH as well as Spotted lanternflies.]

At the end, there was a video played of a young student who created an effective homemade trap for SLFs on her beloved maple trees.

Residents were asked to report the sighting of the SLF to the Village of Irvington through this form so that the Village can gather data on this invasive species.

CJ Reilly brought alive SLFs in special tubes to show residents their current size and spoke about the number of TOHs removed from the Irvington Woods. CJ also spoke about other species that are negatively affecting the health of local native trees.

In summary, let’s all get to work with gardening gloves, our hands, feet, and vacuums. Each female can lay up to 100 eggs during its life cycle so every removal counts. We will get an opportunity to remove their egg masses when they start appearing and share educational materials on how to do so.

Broadway For All Bike Ride on the Aquaduct Friday April 28th - Expand for details

Social Bike Ride & Picnic Party Meeting Friday evening, April 28, on the Aquaduct. 

Let's have some fun and figure out how to make Broadway for Everybody a reality. We'll casually ride the Old Croton Aqueduct from Sleepy Hollow to Irvington, pick up more friends there, and return to Sleepy Hollow. When we get back, it's time for a picnic party! Duncan's Abbey is providing their (quite delicious) "Tarwe Town" wheat beer. Bring a blanket and whatever else you want to consume. Then we'll have a quick presentation/discussion about Route 9. In June, the Dept. of Transportation's consultant will begin preliminary engineering work for making Route 9 a "complete street." We need to make sure they do a GREAT job. 

Let us know if you plan on coming. info at 7:00 pm Gather on the OCA, north side of Bedford Rd (Route 448) 8:00 pm Pickup friends in Irvington (Main St at the OCA) 8:50 pm Pickup latecomers in Sleepy Hollow (at same starting spot), then take short ride to the picnic party spot, where we'll hang out for an hour or so. 

Make sure your headlight batteries are charged. Help Pay for Insurance For this ride to happen, we need to renew our yearly insurance policy. To get insurance, we need money. To get money, we need you to give it: Trustee Meetings At the party meeting, above, we'll be encouraging you to attend Board of Trustee meetings in your village. Mark your calendars now for 7:00 pm for the relevant dates: Sleepy Hollow: 4/25, 5/9 Tarrytown: 5/1, 5/15 Irvington: 5/1, 5/15

Irvington Green Earth Day

Earth Day in Irvington was a success -with students giving away compost and totes, Girl Scouts sharing Maple Syrup tapped from the Irvington Woods, and HS and MS students demonstrating their work with the Harvard Changing Forest program. Thanks @Irvington_GPTF for organizing and sharing resources. Thank you Art XO Studio for the up-cycled bulldog art project. We loved the resulting cyborg collage pup and look forward to seeing the Bulldog Walking Gallery this summer! 

April 23rd 9:30AM - 1PM

Irvington Celebrates Earth Day this Sunday at the Farmer's Market

Come and meet kids from the Harvard Changing Forest program working with C.J. Reilly at the O'Hara nature center and see how they are measuring and coring trees to learn about past and potential tree health. See how the Girl Scouts have tapped trees in the Irvington Woods to create Maple syrup - and sample the product! Meet the high school students with a new plan to get the village composting -on campus and off. Learn from the high school environmental club about a new pollinator garden on campus. 

Kids can participate in a Bulldog up-cycle art project by Art XO with a nod to the up-coming Bulldog Walking Gallery project for Main Street. Bring your weird shaped broken odds and ends and we’ll glue it together to make something anew! 

We are launching the new Resilient Rivertowns Sustainable Living Map, created in partnership with the other municipal environmental committees, with layers for restaurants, shopping, waste, nature and public transport. Be one of the first to take home a free printed copy - while supplies last at the farmer’s market. 

As always,the Green Policy Task Force will be present to talk to you about sustainability in the village and opportunities to have an impact (and some ways saving money).

Earth Irvington: An eco-festival of local solutions!

Presented in partnership with the O'Hara Nature Center and the Irvington Recreation and Parks Department, EarthIrvington is a two-day environmental festival featuring musical performances, film screenings and forums, sustainable eats, and outdoor activities for the whole family. This celebration of nature asks our community to think globally and act locally in order to protect the environment.

The fun begins on Friday, October 1 with locavore fare from nearby eateries and an open-air screening of Wasted! The Story of Food Waste (2017) from Executive Producer Anthony Bourdain (who also narrates) following a Q&A with the documentary’s director, Nari Kye, alongside a panel of leaders from Westchester County organizations whose missions reflect a commitment to sustainability.

The festivities continue on Saturday, October 2 with guided tours of the Nature Center’s 400+ acres of forested trails, “Ask the Expert” tables, hands-on workshops, and a righteously irreverent performance from Reverend Billy and the Stop Shopping Choir, a storied group of self-identified urban activists who use theater of protest, spectacle, and song to fight for climate justice. Explore the full lineup below!

This festival will be held outdoors at the O’Hara Nature Center in Irvington on October 1 and 2. Rain date is October 3. On-site parking is available, and carpooling is encouraged. Questions about accessibility at this event? Email

Great Saw Mill River Cleanup: April 24 2021

Invasives: Why should we care?

Monday, January 13, 2021 
7 p.m., the Irvington Library

This talk was organized by the Pollinator Pathway Project in collaboration with the GPTF. It focused on invasive plants and their impact on our environment.

Dr. Linda Rohleder spoke about invasive plants and how, if left unchecked, they can aggressively undermine biodiversity and the health of our community. She talked about why certain plants are deemed “invasive”, why non-native plants, specifically invasive non-native plants, are so harmful to pollinators that depend on native plants, why invasive plants can grow so aggressively and what can be done to stop and eradicate them. Dr. Rohleder has long been an important voice in addressing how invasive species negatively impact our environment: “Plants are the basis of the food web. Most insects are adapted to eat three or fewer species of plants, and when you change those species, suddenly there are fewer insects and less food for birds and butterflies. Invading species have a ripple effect on the whole environment. If we let them run their course, it would still be green, but there would be a lot less species.”

Dr. Rohleder is the Director of Land Stewardship of the New York – New Jersey Trail Conference and the Coordinator of the Lower Hudson Partnership for Regional Invasive Species Management (“PRISM”). The Lower Hudson PRISM partners with a wide range of organizations and conservation groups who are actively involved in education and outreach about invasive species, management of invasive species, surveying and mapping of invasive species, and/or researching invasive species. Dr. Rohleder received her PhD in Ecology from Rutgers University, where she studied the effects of deer on forest understories. She speaks widely about the threat of invasive species and their impact on our environment.

Broadway For All: Safe Streets

January 8, 2020, the Irvington Library

The first part of the meeting included a presentation called "Broadway for All: The Route 9 Active Transportation Conceptual Plan". We learned about a collaborative five-village consortium of Irvington, Dobbs Ferry, Hastings-on-Hudson, Sleepy Hollow, and Tarrytown that is working to create a modern and green corridor with bike lanes, safer crossings and expanded sidewalks. Bike paths can be used by people of all ages. The plan represents and opportunity to improve student safety for school journey and reduce school drop off traffic. Seniors and handicapped people would benefit from safer and easier pathways while monitor vehicles move efficiently and safely too. Conceptual design can be viewed at (see the final report). We are happy to report that the Irvington Board of Trustees approved a resolution to continue to move forward on the Route 9 Corridor initiative with the surrounding Rivertowns.

If you love the outdoors and want to protect it, please contact us!  

Invasive Removals

The GPTF Invasives Removal Squad keeps monitoring and performing non-native invasives removals to support the health of our local ecosystem. We also organize clean-up campaigns. If you love the outdoors and want to protect it, please contact us!  

Partnership with the Hastings Vine Removal Squad in Hillside Woods

January 10, 2021

The GPTF members worked with the Hastings Vine Removal Squad on the removal of non-native invasive vines such as Oriental bittersweet, English ivy and Porcelain-berry in Hillside Woods. The group also planted the northern red oak (Quercus rubra) and named it “Wisahkakw” after the Lenape People.
