More and more people are interested in carbon emissions analysis and management. You can see this in the growth of awareness-raising campaigns to promote lower-carbon lifestyle choices, as well as voluntary carbon offset programs and proliferating online household carbon footprint calculators.
Now that interest is being harnessed at the community and country level. At the World Bank, partnerships for low-carbon communities are underway with over a dozen cities, as well as several countries. These include efforts to analyze carbon emissions profiles. At the city level, it’s the first step to prioritizing action to not only reduce emissions, but also deliver better services to the poor.
Calculators and tools help people understand the greenhouse gas benefits of effective climate action, but not all tools are created equal. A good calculator should be comprehensive and sophisticated, but also transparent and user-friendly. The best ones not only calculate emissions, but help people manage them.
One example is the CoolClimate Calculator which was developed by a team of students under my direction at the University of California, Berkeley. Chris Jones, Mia Yamauchi, Joe Kentenbacher, and Gang He, among others, developed the tool at the University of California, Berkeley. It measures carbon impacts of specific transportation choices and of energy use, but also includes impacts of water, waste, food, goods and services for both households and businesses. These indirect sources of emissions account for more than 50% of the total carbon footprint of the typical U.S. household.
