Your Earth Hour challenge in 30 seconds: Get one month free carbon offset while helping us collect 10 000 signatures to support Ban Ki-moon in his fight against climate change. In just a couple of weeks we have gathered hundreds of signatures from all over the world, have a look for yourself!

Now Tricorona offsets 1 ton of CO2 for every person who votes by 23 April 24:00 GMT. You will get your name on the UN webpage, our social network channels and a personal certificate if you send us a mail to

One ton of CO2 is equivalent to about 1 month emissions of a person living in a high-income country and at the same time delivers sufficient green electricity to cover the needs of a family for one year in advanced developing countries such as the BRIC.

Happy Earth Hour! Please vote here it takes less than 30 seconds!
