Energy Secretary Steven Chu said on Monday that US President Barack Obama was determined to meet their commitment to hack down carbon emissions.

Steven Chu highlighted the Obama administration's success in hitting deal to enhance fuel efficiency requirements for vehicles and issuance of efficiency standards for appliances.

Speaking on the topic, Chu said, "He absolutely feels that moving toward a clean energy economy is really about our energy security and about our financial security. It's about our economy; it's about the future of the planet."

The Obama administration also gave more powers to the Environmental Protection Agency so that it could regulate carbon efficiently.

But, he did not throw light on how Obama would reduce carbon emissions. It may be noted here that the US President pledged at previous year's UN summit in Copenhagen that the United States would hack carbon emissions blamed for global warming by 17 per cent by the year of 2020 from 2005 levels.

But, Obama's pledge suffered a massive jolt after the bill to require carbon cuts tumbled in the Senate.

It is worth mentioning here that the US' goal to cut carbon emissions by 2020 are less ambitious than those of the EU and Japan, which are using 1990 instead of 2005 as the baseline for measuring cuts.
