Reducing Greenhouse Gas (GHG) emissions from New York’s largest waste facility

From July 2019, PwC committed to offset 100% of our air travel emissions. We are supporting carbon offset projects across the globe that help emission reduction, such as the Seneca Meadows Landfill Gas project in New York.

Setting the scene

Air travel is an essential part of how we service our clients, but it is also one of the largest sources of our carbon emissions. To help reduce the impact of our travel our firms are adopting new meeting technologies, investing in research to advance greener air-travel, raising awareness amongst our people on alternative ways to travel, and reviewing travel policies.

As part of our broader goal to reduce our absolute carbon impact, as of July 2019, we are investing in a range of voluntary carbon offset projects to mitigate the impact of our air travel emissions.

Carbon offset projects prevent, reduce or remove greenhouse gas emissions to compensate for emissions occurring elsewhere. Supporting these projects allows us to have an immediate and positive impact while we investigate and implement longer-term solutions.

How we helped

We support a range of voluntary carbon projects. Underpinning our approach is a set of strict quality criteria, including our offsets being verified by an independent third party to an established standard. Through our approach to offsetting we seek to finance projects with multiple co-benefits including helping to build the market and infrastructure for renewable energy, supporting local economic and social development, and conserving thriving forests.


Seneca Meadows landfill site is the largest non-hazardous waste facility in the state of New York. This award-winning project reduces greenhouse gas emissions by capturing methane from waste that would otherwise be released into the air.

Instead the methane is captured and piped to a nearby landfill gas recovery facility. Here the methane is either captured and used to generate renewable energy or converted to carbon dioxide whose global warming potential is 21 times less than that of methane.

Since its inception the project has helped power over 18,000 local homes. The project has also invested in creating a new 420 acre wetland reserve. The reserve is now home to 220 species of birds, including a number of endangered and threatened birds, amphibians, mammals and insects. At the reserve the project has developed an Environmental Education Center for local children, high school students and adults to visit and learn more about the environment and local flora and fauna.

Seneca Meadows pride themselves on being a reliable and responsible waste management facility. They receive and process; residential waste, e-waste, rechargeable batteries and tyres from cars and light trucks, shredding up to 12,000 tyres every day - 21 million a year. 100 percent of the tyres are then reused onsite, primarily as a drainage material in the landfill liner system.

This project is a standout example that reducing emissions from landfill sites is possible, with Seneca Meadows removing approximately 175,0000 tonnes of emissions from the air every year.1
