Describing himself as "arguably the leading environmentalist in the country", Kennedy promotes populist and anti-establishment environmental policies, claiming that the climate crisis was hijacked by "Bill Gates and the World Economic Forum and the billionaire boys' club in Davos". Kennedy expressed his support for regenerative farming and stated that the priority of environmentalists should be to tackle the "carbon industry". He described the current society and economy as unsustainable and based on a "longtime deadly addiction to coal and oil" and contended that the current economic system rewards pollution; in 2020, Kennedy stated: "Right now, we have a market that is governed by rules that were written by the carbon incumbents to reward the dirtiest, filthiest, most poisonous, most toxic, most war-mongering fields from hell, rather than the cheap, clean, green, wholesome and patriotic fields from heaven." He also stated his support for the Green New Deal resolution of Alexandria Ocasio-Cortez, and announced his plans to implement it. Kennedy spoke out against geoengineering, claiming that geoengineering solutions are an attempt by big business to profit from climate change. Despite his reputation as environmentalist, he voiced his support for agrarian movements, saying in 2023: "If we want to have democracy, we need a broad ownership of our land by a wide variety of yeoman farmers, each with a stake in our system." He is also against nuclear energy, considering it too expensive and too unsafe. Kennedy believes that nuclear energy is a profit-making venture and claims that this solution is promoted by corporate lobbyists rather than environmental activists, stating in a 2023 interview that "it's not hippies in tie-dyed T-shirts who are saying it's dangerous; it's guys on Wall Street with suits and ties".
