Personal carbon trading is the generic term for a number of proposed emissions trading schemes under which emissions credits would be allocated to adult individuals on a (broadly) equal per capita basis, within national carbon budgets. Individuals then surrender these credits when buying fuel or electricity. Individuals wanting or needing to emit at a level above that permitted by their initial allocation would be able to purchase additional credits from those using less, creating a profit for those individuals who emit at a level below that permitted by their initial allocation.
Current proposals include:
Individuals would most likely hold their emissions credits in electronic accounts, and would surrender them when they make carbon-related purchases, such as electricity, heating fuel and petroleum. PCAs could also require individuals to use credits for public transport. Tradable Energy Quotas would bring all other sectors of society (e.g. Industry, Government) within the scope of a single scheme.
Individuals who exceed their allocation (i.e. those who want to use more emissions credits than they have been given) would be able to purchase additional credits from those who use less, so individuals that are under allocation would profit from their small carbon footprint. There are two types of carbon credits, Certified Emission Reduction credits EUAs and CERs and Verified Carbon Credits.
Proponents of personal carbon trading claim that it is an equitable way of addressing climate change and peak oil, as it could guarantee that a national economy lives within its agreed carbon budget and ensure fair access to fuel and energy. They also believe it would increase ‘carbon literacy’ among the public, while encouraging more localised economies. For example, in the UK, the city of Manchester claims it is "the first city to undertake to empower all its citizens with carbon literacy."
Personal carbon trading has been criticised for its possible complexity and high implementation costs. As yet, there is minimal reliable data on these issues. There is also the fear that personal "rationing" and trading of allowances will be politically unacceptable, especially if those allowances are used to buy from industries who are already passing on costs from their participation in carbon levy or trading schemes such as the EU ETS.
