Negative side “Japan should initiate a Pan-Pacific International Carbon Trading”
by IKENO Shuma
Japan should initiate a Pan-Pacific Carbon Tax
１. On the model, a carbon tax is superior to a carbon trading.
2. A carbon tax can be expected effective.
３. A carbon tax is familiar to many countries.
Background
Background
A model of a single Polluting Firm. B is government revenue.
A model with Two Polluting Firm. The shadow square is government revenue.
Both a carbon tax and carbon cap-and-trade
will achieve the same level of increased efficiency by achieving the optimal abatement level at the minimum cost.
Japan’s debt against GDP is over 230%. Japan needs tax revenue. And, payment risk is high.
2. A carbon tax can be expected effective.
World carbon dioxide emissions by fossil fuel is 45.4% in 2005
Fossil Fuel Emissions of the world is increasing.
In Japan, coal-fired power generation is increasing.
Fossil fuels are a major cause of global warming.

IPCC Fourth Assessment Report
Keep the average temperature rise within 2℃ in
2050 comparing the Industrial revolution before.
The amount of CO₂ emission around the world
have to be reduced more than 50% by 2050.

of $30 per tonne was
adopted by the
government, they can cut
9.2% CO2 emissions.
