Diners are being encouraged to eat more pork and chicken instead, as they produce fewer carbon emissions.
A Government-sponsored study into greenhouse gases has found that producing 2.2lbs of lamb was the equivalent of releasing 37lbs of carbon dioxide.

Power plants could store carbon dioxide under North SeaOther foods such as tomatoes only produce 20lbs of CO2 while potatoes release about 1lb of CO2 for each 2.2lbs of food.
Lamb produces so much carbon dioxide because sheep belch so much methane, which is a potent greenhouse gas. Cows are also damaging, releasing the equivalent of 35lbs of CO2 per 2.2lbs. Previous studies have shown that a herd of 200 cows can produce annual emissions of methane - roughly equivalent to driving a family car more than 100,000 miles on more than four gallons of petrol.
The study also found that alcoholic drinks contribute significantly to emissions, with the growing and processing of hops and malt into beer and whisky producing 1.5 per cent of Britain's greenhouse gases.
"Changing our lifestyles, including our diets, is going to be one of the crucial elements in cutting carbon emissions," said David Kennedy, chief executive of the Committee on Climate Change.
Mr Kennedy, who says he has stopped eating doner kebabs because they contain lamb, added: "We are not saying that everyone should become vegetarian or give up drinking but moving towards less carbon intensive foods will reduce greenhouse gas emissions and improve health."
The climate committee is analysing emissions from farming and is set to suggest measures to reduce them.
The Carbon Trust, a government-funded firm, is working with food and drink companies to calculate the "carbon footprints" of products.
Britain is committed to cutting greenhouse gases by 80 per cent by 2050.
More than a third of all methane emissions in the country is produced by farm animals. By volume, methane is 20 times more powerful at trapping solar energy than carbon dioxide.
