This week on Earth Beat's Christmas special: food footprints, communal ovens, green beer, toys made from recycled aerosol cans, and how reindeer herders are being affected by global warming.

Listen to the programme in full:

THE FOOD FOOTPRINT
We’ve all heard of and probably calculated our carbon footprints, but have you calculated your food footprint? Marnie cooks Christmas dinner, calculates her footprint online, and talks to Jan Juffermans of De Kleine Aarde (The Small Earth) to find out what it all means.

Plus, Sweden has just introduced carbon emissions labeling in its supermarkets. Earth Beat’s correspondent Rebecca Martin goes Christmas food shopping in Stockholm with a smaller footprint in mind.

COMMUNAL OVENS
Public parks in Toronto have seen a surge of wood-fired bake ovens in recent years. They’re communal, open to anyone who wants to use them, and have changed the lives of the people in the surrounding neighbourhoods. Earth Beat’s correspondent Naheed Mustafa goes to one to talk to its users.

URBAN WINES
Local wine is hard to come by for Londoners, but now there’s Chateau Tooting, made by the Urban Wine Company using grapes found in backyards across the city.

TRYING TO MAKE SUSTAINABLE BEER
Take a few old dairy containers, some local grain, and a Dutch windmill to house your brewery, and you have some tasty, award-winning beer. Earth Beat producer Anik See goes to Brouwerij de Molen in central Holland to speak to owner Menno Olivier about starting a sustainable brewery – what works, what doesn’t, and how the end result tastes.

MEXICAN RECYCLED TOYMAKER
Miguel Ramirez makes toys in Oaxaca City. Not just any toys – these are made from empty aerosol cans. Ramirez crafts them by hand into trains, cars and airplanes, and Earth Beat correspondent Shannon Young visits him to see the process.

CLIMATE CHANGE AND RUSSIAN REINDEER HERDERS
With the tundra freezing later and later every year, the Saami, native inhabitants of the Kola Peninsula in Russia, have a shorter – and more dangerous – hunting season. Unstable ice affects their ability to hunt reindeer, something they have been doing for centuries to survive. Earth Beat correspondent Geert Groot Koerkamp visits them to hear their story.

YULETIDE WOES
Some people it seems, feel more responsible about reducing their consumption than others. One of them is Catrin Rogers from the Welsh capital Cardiff. She joins Earth Beat to offer her Christmas commentary.
