It should be noted, however, that there will be different marginal
abatement costs across states, and so aggregate reductions would not be achieved cost - effectively.
To carry this out requires a uniform price on emissions from different regions within a given year (to equalize marginal
abatement costs across different countries).
Not exact matches
The SkyShares model enables users to relate a target limit for temperature change to a global emissions ceiling; to allocate this emissions budget
across countries using different policy rules; and then uses estimated marginal
abatement costs to calculate the
costs faced by each country of decarbonising to meet its emissions budget, with the
costs for each country depending in part on whether and how much carbon trading is allowed.
An emissions price path with this property precludes all opportunities for arbitrage because the discounted marginal
cost of
abatement is constant
across time.
Second, it is the least costly approach in the short term, because
abatement costs are exceptionally heterogeneous
across sources.
The market mechanism would ensure that the prices were equalized
across different countries, and this would lead to equalizing marginal
costs of
abatement across countries and to a global minimum
cost.
«The court's decision to dismiss the lawsuit regarding the Zero Emission Credit segment of New York's Clean Energy Standard (CES) is good news for New York's climate efforts and citizens
across the state because it preserves the most
cost - effective source of carbon
abatement available to consumers.
