The 47-year-old Oscar-winning actor and environmentalist has acquired an equity stake in Telmont Champagne House located in Damery, near Épernay, France.

'From protecting biodiversity on its land, to using 100% renewable electricity, @maisontelmont is determined to radically lower its environmental footprint. Proud to join as an investor in Champagne Telmont,' DiCaprio tweeted for his roughly 19.5 million followers. 

The Telmont Champagne House was founded in 1912 in the wake of the Champagne Riots by local winegrower Henri Lhôpital, according to a release announcing the investment.

Champagne Telmont has remained familial with fourth generation Bertrand Lhôpital currently serving as cellar master and head of viticulture.  

'Champagne Telmont, together with its partner wine-growers, has set its sights on producing 100 percent organic champagne, ensuring a completely sustainable production lifecycle in the coming years,' DiCaprio said in a statement released Tuesday by Champagne Telmont. 

The actor's investment was lauded by Champagne Telmont as an endorsement of their approach.

'Leonardo DiCaprio's decision to become a shareholder sends Telmont a strong message of support that will encourage us as we carry out our ambitious plans. We share the same convictions and the same commitment to protecting the environment,' said Ludovic du Plessis, chairman & shareholder of Champagne Telmont in a statement. 

The Rémy Cointreau group purchased a majority share of Champagne Telmont in October 2020 after identifying with its eco-friendly values.

Champagne Telmont has a goal of converting its entire vineyard to 100 percent organic agriculture by 2025 and to help its partner growers reach full conversion of their vines by 2031.

Less than four percent of Champagne vineyards currently are certified organic.

The conversion will include the elimination of herbicides, pesticides and chemical fertilizers.

Champagne Telmont since last June has banned gift boxes to reduce packaging waste. It also has stopped buying clear bottles made from zero percent recycled glass and has switched to classic green champagne bottles made from 85 percent recycled glass.

DiCaprio has become a staunch supporter of environmentalism and focused recently on environmental documentaries.

He was an executive producer of Virunga, Cowspiracy: The Sustainability Project, The Ivory Game and Catching The Sun.

He also produced, hosted and narrated the 2016 documentary Before The Flood about climate change and narrated the 2019 global warming documentary Ice On Fire. 

DiCaprio has a starring role in the apocalyptic black comedy Don't Look Up with the catastrophic impact of a humanity-destroying comet serving as an allegory for climate change.

Don't Look Up received four Academy Awards nominations, including Best Picture and Best Original Screenplay.
