You bet... As you'll probably have noticed, it doesn't take much to shed a tonne of CO2 - and considering a tonne is about the equivalent of a hot air balloon that's a considerable amount.

And, what's more, you don't have to stop at one tonne. There are a myriad of ways in which you can live a more energy efficient life and over the next few months we will be introducing more pledges to show you how.

There's no escaping the fact that some of the biggest climate criminals can be found in boardrooms and ministerial offices. But these people are in jobs because they have customers and constituents - and if their patrons and voters insist on change they better listen up.

OK, it's not as simple as that. 'What about India and China?' we hear you cry. But despair and denial don't fix problems, collective action and passion do. Get on board, get your mates on board and you can guarantee a lot more people will get on board too.

Your CO2 pledges are only the tip of the iceberg (which there won't be many left of unless we get busy). Communication is the most effective weapon against the onslaught of global warming so, as well as cutting back on your own CO2 emissions, letting others know what you are doing and why is equally important.

Hassling the people you live and work with, in the nicest possible way of course, will make them realise just how easy it is to live a cleaner, greener lifestyle - and if you're the competitive type, you can always compete with each other to see who can reduce the most.

Our clever web developers gathered the figures used for MY CO2 from numerous governmental departments, non-governmental organisations and specialist environmental research facilities and companies.

Please find below a complete list of the MY CO2 data sources with links to their websites.

• Building Research Establishment Ltd. (BRE)
• Carbon Neutral Company
• Department for Environment, Food and Rural Affairs (defra)
• Environmental Protection Agency (EPA - U.S.)
• Market Transformation Programme (MTP)
• National Atmospheric Emissions Inventory (NAEI)

Mankind is currently emitting 26.5 billion tonnes of CO2 per year, rising three quarters of a billion tonnes every year. We aim to bring this down by at least one billion tonnes a year - with the aim of raising that to 10 billion tonnes a year within a decade.

We know, and we hope you have just found out, how easy it is to shed one tonne of CO2. Hopefully in time you'll be able to shift a few more tonnes, which will in turn bring us much closer to our goal.

So, to put it in simplistic terms, if 300 million people globally cut back their CO2 emissions by just over three tonnes, then we've reached our goal. In fact there are countless permutations of how we can reach our target, although the more people on board the better.
