Zerofootprint Personal Carbon Manager gives you an in-depth analysis of your carbon and wider ecological footprint. You customize the calculator to your personal circumstances, and use it to measure your ecological impact in terms of carbon emissions and other factors. The Personal Carbon Manger allows you to explore the impact of making changes to your lifestyle, and to store your current footprint and track over time the impact of changes you make. It enables you to link with other users in a social network where you can share and encourage carbon initiatives. It also links to a marketplace of green products and services, as well as to a calendar of green events and environmental news.
