Senior U.S. and Chinese officials said Thursday the two countries needed to urgently increase carbon capture utilization and storage demonstrations and enable commercial deployment of the technology by the end of the decade.

Carbon capture and storage "is one of the low-carbon technology options critical to the global quest to reduce carbon dioxide emissions to the atmosphere," said a joint statement from the Carbon Sequestration Leadership Forum, attended by U.S Secretary of Energy Steven Chu and others.

It called on leaders attending the United Nations' climate change conference in
South Africa at the end of the year to recognize the role of carbon capture and storage in reducing greenhouse gases, and said financing for pilot programs remained a challenge.

Many pilot programs are occurring in
China , though foreign developers say they are concerned about protecting intellectual property when partnering with Chinese energy and utility companies. Chu said both the U.S. and China needed to protect their respective intellectual property.

"We intend to develop a lot of intellectual property together that we can also share," he said.

On Wednesday,
China 's Ministry of Environmental Protection said it would tighten emission controls on thermal power plants for the first time since 2003. The new standards, which take effect Jan. 1, take aim at pollutants including sulfur dioxide and nitrogen oxide. They will also require mercury emissions be monitored for the first time.

The new controls could cost the thermal power industry CNY260 billion ($40.7 billion) in upgrading its facilities, the ministry said.

Increasingly stringent government pollution regulations have made
China a destination for renewable energy research and development. Its wind and solar companies, for example, are among global industry leaders and are undercutting renewable energy companies in the U.S. and elsewhere.

Government subsidies for Chinese renewable energy companies have become a sticking point in U.S.-China relations.
Washington has complained about a lack of transparency for some subsidies. Under pressure from the Obama administration, China this summer agreed to end some subsidies for its wind equipment manufacturers.

Earlier this month, wind turbine designer American Superconductor Corp. said it was suing
China 's largest wind-turbine manufacturer, Sinovel Wind Group Co. (AMSC), for corporate espionage. The U.S. company said one of its Austria-based employees sold turbine-controlling software to Sinovel for $1 million. Sinovel has denied any wrongdoing.
