More than 1,300 people have signed a petition calling for the Member of Parliament for Hastings and Rye to leave her position as climate change secretary.
Amber Rudd has been subject to criticism over her policies on renewable energy and fossil fuels.
But a petition calling for a vote of no confidence was launched on September 16, and is currently on 1,304 signatures.
Liberal Democrat canditate for Hastings and Rye in 2010 and 2015 Nick Perry supports the petition because he believes Ms Rudd has gone back on her pre-election promises.
“Before the General Election the Conservatives were undermining what they called ‘Green Crap’,” he said.
“During the election I questioned Amber extensively, and she said that the climate and green industries were safe in her hands.
“Since the election we have seen her fast-track fracking, cancel the zero carbon homes programme, and forget to disclose her brother’s significant lobbying interests in the energy sector.
“This is what a real Conservative approach to the environment looks like, and how different from the last five years when the Liberal Democrats were in charge of the department.
“In my opinion, the Conservatives’ commitment to green infrastructure – a powerful regeneration tool for our area and across the country – is as strong as their City funders’ wish to pay their fair share of tax.
“I hope your readers will go online and sign the petition. Up and down the country people are now openly saying there needs to be a red light on Amber’s Green betrayals.
“Sadly, I don’t think she is up to this very important job.”
Ms Rudd told the Observer that scrapping solar power projects and promoting fracking was to cut costs.
But petitioners believe she has overstepped the mark ahead of an international conference on climate change, which is unforgiveable.
The petition says: “The world needs a new agreement at the UN Climate Change Conference in Paris to de-carbonise and avoid excessive global warming.
“The Secretary of State for Energy & Climate Change is undermining renewable energy whilst promoting fossil fuels, the UK needs a credible voice at this vital conference.”
The petition needs to reach 10,000 votes before it the Government responds and 100,000 before it is debated in Parliament.
All petitions last six months so it will expire on March 16.

Ms Rudd has been contacted for comment.
