Input: Consider Input: California and New York issued a joint statement saying they would continue the fight against climate change.
Environmental groups have hired a host of lawyers to challenge Mr Trump's move that boosts fossil fuel production.
Mr Trump said he wanted to end "job-killing regulations".
His supporters believe that ending the climate change rules brought in by Barack Obama will create thousands of jobs in the gas, coal and oil industries.
The governors of New York and California summed up opponents' views by saying Mr Trump's stance was "profoundly misguided and shockingly ignores basic science".
In a joint statement, Governors Jerry Brown of California and Andrew Cuomo of New York, both Democrats, said: "With or without Washington, we will work with our partners throughout the world to aggressively fight climate change and protect our future."
The two states have set even stricter targets on reducing greenhouse gas emissions than required by Mr Obama's rules and have far-reaching plans for converting to renewable energy sources for producing electricity.
Governor Brown said: "Erasing climate change may take place in Donald Trump's mind, but nowhere else."
A host of legal issues could be in the pipeline.
California has a special waiver allowing it to enforce tougher measures on vehicle emissions. Mr Trump could rescind that - but this would lead to a fierce challenge.
He could also ask Congress to revoke the Clean Air Act.
Back in 2007, the US Supreme Court ruled that carbon dioxide gas was a pollutant under the Act.
Some experts believe that the ultimate goal of Mr Trump's executive order is to overturn that ruling.
Already tied up in the courts is Mr Obama's Clean Power Plan (CPP), which seeks to cut fossil fuels from electricity production.
The BBC's environment correspondent, Matt McGrath, says Mr Trump will let the CPP fester there while coming up with a much weaker replacement.
David Goldston, of the Natural Resources Defence Council, said activists were gearing up for legal challenges.
He said: "The president doesn't get to simply rewrite safeguards; they have to... prove the changes are in line with the law and science. I think that's going to be a high hurdle for them."
Any legal challenges would dovetail with action to win over public opinion.
Jeremy Symons, of the Environmental Defence Fund, told Associated Press: "In terms of the big picture, our strategy is simple: shine a spotlight on what is going on and mobilise the public against these rollbacks."
But Mr Trump's move does have supporters.
US Chamber of Commerce president Thomas Donohue said: "These executive actions are a welcome departure from the previous administration's strategy of making energy more expensive through costly, job-killing regulations that choked our economy."
Mr Trump's Energy Independence Executive Order suspends more than half a dozen measures enacted by his predecessor.
Although during his election campaign he also vowed to pull the US out of the Paris climate deal agreed in December 2015, he has not spelled out the US intentions.
Whatever the US chooses, the EU, India and China say they will stick to their pledges made in Paris.
On Wednesday, Chinese foreign ministry spokesman Lu Kang said: "No matter how other countries' policies change, as a responsible large developing country, China's resolve, aims and policy moves in dealing with climate change will not."

Output: Opponents of President Donald Trump's decision to scrap his predecessor's climate change policies say they will organise a public campaign and pursue legal avenues to challenge it.


Input: Consider Input: Lebanon now has "the highest per capita concentration of refugees worldwide", said the head of the UN refugee agency.
"For Lebanon, a small nation beset by internal difficulties, the impact is staggering," he added.
About 9.5 million people, almost half of Syria's population, have fled their homes since the start of the conflict.
More than 2.5 million have fled the country, with large numbers being taken in by Turkey, Jordan, Iraq, Egypt and others.
However Lebanon is bearing the biggest burden of all - the number of Syrian refugees there now amount to a quarter of the local population.
By Jim MuirBBC News, Beirut
Everybody knows that the real number of Syrian refugees in Lebanon is already well past the million mark, but the fact that that many have now been officially registered is yet another grim milestone as the conflict grinds on.
Lebanon's the smallest and most vulnerable of Syria's neighbours, yet it's taken in by far the largest number of refugees - one for every four of the country's own people.
That's a huge strain - the foreign minister said last month that it threatened Lebanon's very existence, and it's growing all the time, with about 2,500 new refugees being registered every day.
The UN has only received 14% of the funding it's asked for. That means that relief has to be cut back and carefully targeted to the most needy.
The BBC's Jim Muir in Beirut says this is a huge strain for Lebanon, the smallest and most vulnerable of Syria's neighbours.
Last month the Lebanese foreign minister said the crisis was "threatening the existence" of his country.
"The Lebanese people have shown striking generosity, but are struggling to cope," Mr Guterres said.
The UN's refugee agency, UNHCR, notes that the influx of refugees is accelerating.
"Every day, UNHCR in Lebanon registers 2,500 new refugees: more than one person a minute," the agency said in a statement.
International aid agencies are finding it increasingly difficult to cope with the flow of refugees.
UNHCR has only received 14% of the $6.5bn (Â£4bn; 4.7bn euros) funding it has asked for.
The hardships many refugees are facing was dramatically highlighted last week when a mother with a sick husband and four children set fire to herself in protest at not receiving help. She was critically injured.
The civil war in Syria between Sunni-led rebels and the government of Bashar al-Assad has also fuelled sectarian tensions in Lebanon, which has a large Sunni and Shia Muslim population.
Hundreds of people in Beirut and other parts of the country have been killed in violence between opponents and supporters of President Assad.

Output: The number of refugees who have fled Syria and registered in Lebanon has surpassed the "devastating milestone" of one million, the UN says.


Input: Consider Input: Sean Rigg, 40, who had schizophrenia, suffered a cardiac arrest at Brixton police station on 21 August 2008.
The inquest in 2012 found police used an unsuitable level of force with him.
Sgt Paul White gave evidence at Mr Rigg's inquest. The CPS said it had reviewed the case at the family's request and would prosecute Mr White.
A second officer was originally referred to the Independent Police Complaints Commission (IPCC) on suspicion of perjury and perverting the course of justice.
Sue Hemming, head of the Crown Prosecution Service's (CPS) Special Crime and Counter Terrorism Division, said she had considered the evidence against the second officer but concluded there was insufficient evidence to prosecute.
Sgt White, who was based at Lambeth Borough at the time of Mr Rigg's death, is due to appear before Westminster Magistrates Court on 8 September.
In a statement, Scotland Yard said it was aware of the CPS decision to prosecute an officer and the officer concerned was on restricted duties.
It said it was also co-operating with two investigations by the IPCC following the death of Mr Rigg.
The first is a re-investigation into the circumstances surrounding the death and the second is an investigation into the evidence given by Met officers at the inquest into Mr Rigg's death. The musician had been arrested on suspicion of attacking a man in Balham, south London
The statement also said: "The Metropolitan Police Service would again like to emphasis our sympathy to Mr Rigg's family and acknowledge their loss."


Output: An officer with the Metropolitan Police is to be charged with perjury over evidence given at the inquest of a man who died in custody in south London.
