As well as showing your loved one how much you care, Valentine's day is a great way to show that you love the environment too. So here are PeopleProfitPlanet's top tips on how to green your Valentine's day.

Around a billion Valentine's cards are sent globally each year (1), making it the second largest card-sending holiday of the year after Christmas but most are thrown away. Instead, reduce your carbon footprint by buying a recycled card or why not make your own using recycled materials or send a charity ecard?

You could also be more creative with the flowers you buy. Red roses come from Holland, South America and Africa so to reduce their carbon footprint look for organic or Fairtrade (2). Or, if you would prefer something UK-grown narcissi, daffodils, tulips and chrysanthemums are all in season. Alternatively you could buy a house plant, they save packaging, last longer and absorb CO2!

Valentine's day just wouldn't be the same without chocolate so why not buy organic or Fairtrade chocolates which are greener and more ethical and taste good too.

And finally, when your fun is over, don't forget to compost and recycle your waste.  Happy Valentine's!
