Hudson Farm

Andover, New Jersey


Improved Forest Management

Technical details

Hudson Farm, in northern New Jersey, includes more than 3,600 acres of mixed hardwood and conifer forest. In 1904, railroad magnate John P. McRoy hired a New York architect to design a 20-room estate house at what was then McRoy's dairy farm and country retreat. The farm got its current name in 1917 when the Hudson Guild, a social services organization based in the New York neighborhood of Chelsea, bought the property as a camp for city children. In 1921, forester and conservationist Benton MacKaye conceived the idea for the Appalachian Trail during a gathering at the estate house.

In 1997, the guild sold the property to businessman and philanthropist Peter Kellogg. Kellogg restored the estate house, added additional land, and opened the property as the Hudson Farm Club, a private hunting and outdoor club. The acreage also includes shooting ranges and the headquarters of the firearms company Griffin & Howe.

Today, Hudson Farm pioneers wildlife conservation initiatives throughout the region and serves as a local community steward. The Hudson Farm Foundation has given more than $7 million to local charities, including conservation and species protection projects, various medical causes, veterans groups, food banks, fire departments, and programs promoting safe and responsible hunting. Hudson Farm partners with the New Jersey Audubon Society and the US Department of Agriculture's Natural Resources Conservation Service.

This project meets United Nations Sustainable Development Goals 6 (clean water and sanitation), 13 (climate action), and 15 (life on land). It generated its carbon offsets by committing to maintain the forest's carbon dioxide stocks above the regional common practice.

A carbon offset represents the reduction of 1 metric ton (2,205 pounds) of carbon dioxide emissions. That reduction can be accomplished in many ways. For example, a project might capture and store CO2 before it’s emitted or, as the Hudson Farm project does, absorb (sequester) CO2 from the atmosphere. Other projects might reduce the need for producing energy from fossil fuels by producing it from a clean, renewable source instead, or by decreasing energy use through improved efficiency.

Cloverly buys offsets that meet accepted standards for being real, measurable, verifiable, permanent, and additional. "Additional" means that the carbon savings would not have happened without the offset project and that the project would not have happened unless it got certified to sell carbon offsets. American Carbon Registry oversees verification of the Hudson Farm project. You can find verification documents at

Projects can produce many offsets during a year, depending on how many tons of carbon they avoid, offset, or sequester. So a project may appear more than once in the Cloverly portfolio. You can tell the year of the offset by the date in the web address for each project: "12-months-starting-[month]-[year]." For a list of all the projects in our portfolio and an interactive map, see
