Total emissions is calculated by adding all emissions in carbon dioxide equivalent (CO2e) for a year.The Nature Conservancy has a ready carbon calculator powered by Cool Climate Network at the University of California at Berkeley where one can calculate and compare individual emissions. there is no central national Cap and Trade carbon pricing.The Earth Institute in Columbia University in 2016 noted that there were 40 countries and 26 cities that have carbon pricing covering 12% of global emissions. Instead pricing takes place in the Northeast and mid-Atlantic States and California.Environmental XPRT lists carbon markets world-wide, like Environmental Credit Corp, Ctrade, Texas Climate and Carbon Exchange, and The Carbon Desk.Pricing fluctuates based on region, market conditions, and the certification program.To show how the process works, each step of measuring and pricing carbon are shown by considering an example of a family of two living in California based on the known 2015 data.
18) to calculate emissions: EFs for coal, fossil fuels, biomass, natural gas, electricity, and petroleum products are provided by Environment Protection Agency (EPA) Greenhouse Emission Inventories published in 2015 (pg. This document also gives emissions from cars according to year of production and fuel, and for vehicles used in agriculture, construction, and aviation (pg. The AP-42 released and periodically updated by EPA also provides EFs for many industries.To calculate the amount needed to buy carbon credit from an reforestation project from Gold Standard at the 2015 price, one must multiply total emissions with .86 or 13€/t CO2e.3.263 t CO2e x .86$ = .225 So the couple wishing to offset their emission (of 3.263 t CO2e) due to electricity use, could buy carbon credits worth .225 in a carbon market that is then spent to plant trees for carbon sequestration.A credit is a measure representing one megatonne (a mass equal to 1,000 kilograms) of greenhouse gas emissions (GHGs) either saved from being emitted or removed from the Earth's atmosphere explains the Gold Standard.An international carbon credit system was first ratified by the the Kyoto Protocol of 1997.
So a household of two uses around 10,000 k Wh or 10 MWh of electricity (One Megawatt or MWh = 1000 k Wh).
