The pro-EU party promised to give voters the option to remain in the bloc if they do not like the final terms of the Brexit negotiations. "It is going to wreck our children's future for decades to come".
The party also intends to expand renewable energy, aiming to generate 60% of electricity from renewables by 2030, restoring government support for solar PV and onshore wind in appropriate locations (helping meet climate targets at least cost) and building more electricity interconnectors to underpin this higher reliance on renewables.
Mr Farron said: "Air pollution in the United Kingdom is a killer".

He said: "On the biggest question facing all of us, Brexit, which has such huge implications for our young people and our future, Corbyn ordered his MPs to stand down against Theresa May's government".
On the topic of the Javelin Park incinerator, Mr Wilkinson, who was born in Weston-super-Mare, said that whilst he was not necessarily against the technology there were better ways of tackling waste in the county.
Labour would replace the Tories' Brexit white paper with "fresh negotiating priorities" with a strong emphasis on retaining the benefits of the single market and customs union, rejecting the idea of leaving without a deal. I believed passionately that our children would have a brighter future if Britain remained in the European Union.
Among the other major policies advocated by the Lib Dems are an extra 1 pence on income tax rates to raise 6 billion pounds ($7.8 billion) to spend on the state-run National Health Service and a plan for a 100 billion pound infrastructure investment to help build 300,000 homes a year and improve road and rail links.
Alun Griffiths, a councillor and the party's Parliamentary candidate for Bradford West, also described the Liberal Democrats' pledge to legalise cannabis as "a sensible, straightforward thing to do". The manifesto also commits to trying to double SME numbers involved in the digital economy through the provision of capital expenditure focused on business in non-digital sectors.
"The Liberal Democrats can not be trusted to stand up to the Tories - and as we know their manifesto pledges are not worth the paper they're written on". Any party seeking to lead the country after this election should be prepared to take bold action to safeguard them.
Speaking later at the official launch of the manifesto, Mr Farron lumped Mrs May in with far-right figures like Donald Trump and Marine Le Pen, accusing the PM of allowing her party to be "taken over" by an agenda shaped by former UKIP leader Nigel Farage. The Lib Dems oppose fracking but suggest that nuclear will play a role in the UK's electricity supply.
The prime minister's Conservative Party has surged in the polls in recent months, now leading with 49 percent of the vote according to a YouGov poll published on May 12.
He added: "The costings look like they add up in the sense there are a set of numbers for tax increases they propose, all of which are much more modest than what we saw yesterday [from Labour's manifesto]".
UK Prime Minister Theresa May today (18 April) announced she will call a snap general election for 8 June.
