California set a $10 price floor for its first allowance auction in November. The carbon allowances were actually sold at $10.09 a ton.
In its second auction in February, the price rose to $13.62 a ton, and the price then hit a record of $14 in the third auction in May.
Gary Gero, president of the California-based Climate Action Reserve, said the most affected companies are electric utilities, petroleum refineries and large manufacturing facilities.
Most companies will assess the costs of implementing on-site emission reductions relative to the cost of an allowance or offset and then pursue the most cost-effective reduction opportunities.
"This is the very point of a cap-and-trade program; it provides the largest amount of emission reductions at the least possible cost, thereby reducing the economic impact on businesses and consumers," said Gero.
This program will result in the shifting of energy production to cleaner fuels and technologies as the program progresses and after the least expensive reductions have been identified and implemented, he added.
The problems of the EU's ETS, the largest player in the global carbon market, are mostly due to two related issues: the excessive allocation of permits and carbon price volatility.
Justin Dargin, energy and carbon markets expert at the University of Oxford, said China should not be overly concerned about the success or failure of carbon markets outside its jurisdiction.
The reason that China is concerned about the development of carbon markets has mostly to do with transitioning its economy away from an energy-intensive model.
The introduction of energy-efficient industrial equipment would also lower China's aggregate energy consumption. That would help China meet its energy security goals for the medium and longer term. These goals are relatively independent of developments outside of China, said Dargin.
Yet, China can learn from other jurisdictions and therefore should pay close attention to the best practices and "lessons learned" elsewhere.
Dargin suggested setting a carbon price floor that is high enough to create incentives for industry to invest in clean technology, while at the same time not being too high to hinder industrial competitiveness. The price band should also attempt to minimize volatility as much as possible.
Xie Zhenhua, China's top climate change official, said in April that China will draw lessons from the EU's ETS, the world's biggest emissions trading system, which has had a lingering oversupply of carbon allowances and low prices.
