Follow the great example of today's top Kiwi sportspeople, who show how easily they could cut carbon emissions in their past year's travel and lifestyle choices, at Project Lifefoot website. http://www.projectlitefoot.org This site has a free 'past 12-month' carbon calculator, which is based on reliable science as used at Landcare Research's calculators at carboNZero website. Their calculators are also available free - four versions for households, schools, smaller businesses and for holiday travellers: http://www.carbonzero.co.nz/calculators

Remember that 10:10NZ's aim is to reduce our total carbon emissions to atmosphere, not to offset emissions or trade them. However it is helpful to know what last year's emissions added up to, as a baseline for measuring this year's 10% reduction.
