We have been developing an ever closer relationship with China on climate change for many years which has led to collaboration on carbon trading, offshore wind development, on low-carbon buildings, on nuclear energy, and on carbon capture and storage - to name just some of the ways in which we're working together.

We now have the economics confirming that not only is climate action required to reduce climate risks, but that it is vital to building long-term, sustainable economic growth.

Any genuine progressive should work together to stop Brexit - this is a national emergency, requiring national cooperation.

Liberal Democrats will not rest until we have stopped Brexit.

Liberal Democrats are proud to be the main U.K. political party leading the Remain campaign. Being pro-E.U. is in our DNA: internationalism, tearing down walls rather than building them, is at the heart of who we are as a party.

We are a million miles from the Tories. While we promote international co-operation and human rights abroad, they pull up the drawbridge.

When I was energy and climate change secretary I sat around a cabinet table with Gove, and he couldn't help playing to the Tory climate-sceptic audience. As education secretary, he tried to ban climate change from the geography curriculum. After an angry exchange of letters with me, he eventually backed down.

What's most disappointing about May's failure on climate change is that Britain played such a pivotal role in securing international agreement on it in the first place.

Abuse of human rights and international law demand resolution - whoever is responsible.

Brits, Indians, Frenchmen and Belgians fought side by side in the trenches of the Somme and on the fields of Ypres.

When we fight to uphold the rule of law, it's vital we uphold the rule of law as we fight. Otherwise we simply play into the hands of the terrorists and undermine our values and system of justice.

No-deal Brexit could be Boris Johnson's biggest deception yet - worse than the Boris bus or the lies that had him sacked as a Times journalist or as a spokesman by the then Tory leader, Michael Howard.

My experience as energy and climate change secretary - in the months I spent battling George Osborne over the budget for investment in low carbon, and in the daily attrition with Eric Pickles over onshore wind - was that many Conservatives simply regard their commitment to climate change action as something they had to say to get into power.

I've been a young carer, an adult carer and a parent carer.

You don't need to be a John Maynard Keynes to understand that if Britain leaves the European market, a border will have to be put in place - and that would break U.K. obligations in a treaty lodged at the United Nations.

Our party's greatest achievements have always been delivered from the radical centre-left.

Ed Miliband rails against energy companies and says the market isn't working. But wasn't he Britain's first secretary of state for energy and climate change in 2008?

Energy is one of those things that brings Europe together in terms of our security needs, affordable energy and climate change.

We need to invest in home-grown clean energy that will bring cheaper prices in the long run, shielding consumers from volatile international fossil fuel markets.

The very idea that human beings are held in bondage is sickening.

One of the most exciting opportunities created by renewable energy technologies like solar is the ability to help the world's poorest develop faster - but more sustainably too.

Alongside energy efficiency, renewables and abatement, I believe safe nuclear power, with manageable waste, can play an important role in reducing greenhouse gas emissions, as long as it is cost competitive with other low carbon generation.

Nuclear represents a significant low-carbon opportunity. The electricity it produces is green and reliable.

Diplomacy is essential if we are to find peaceful resolutions in times of tension.

On climate change, Britain is leading in Europe.

Climate change remains the biggest threat to our civilisation, economy and security - even bigger than Brexit.

Putting Michael Gove in charge of the Department of the Environment is much like putting a wolf in charge of the chicken coop.

We should be working with our European allies, not turning them into opponents.

We should be redoubling our own efforts to combat climate change, not watering them down.

Just as Donald Trump is abrogating America's responsibility to lead the fight against climate change, Theresa May is evading Britain's role.

Brexiteers often hark back to the blitz. Maybe they think the 'Britain standing alone' motif adds much-needed heroic purpose to a Brexit future in which Britain stands without trading partners or allies to tackle climate change.

People need to understand what a party is about. And you can't define a party by an issue which will go, which is transitional.

Caring is tough.

I am not going to give up on renewable energy.

What I saw in my first year as secretary of state was a danger that if Britain didn't lead the way on climate change nothing would happen. I thought: If I don't lead, no one else is going to.

The Tories wanted to get rid of fuel poverty targets. I stopped them.

We fought hard for green taxes and won.

Climate change is hugely threatening to our way of life, in the U.K., Europe and the world.

We are strong supporters of energy efficiency. The question is: what is the most appropriate way of doing it?

I don't ever talk about red lines whether in coalition negotiations with other partners or in Europe. It is important that we listen to others and find a way forward.

I can't stand by, the Liberal Democrats will not stand by, to see disabled people lose their rights, lose the care they need, when they need it the most.

I'd say that I'm a pro-European.

Britain's energy markets were a mess in 2010.

Britain needs a diverse energy mix - home grown renewables, new nuclear, a switch from dirty coal to cleaner gas, and, when the technology is ready, carbon capture and storage. Diversity will keep the lights on and ensure we go green at the lowest possible cost.

By leading on a strong emissions reduction target, the U.K. is persuading others on the need for member states to have the freedom and flexibility to develop their own energy mix to achieve these ambitious reductions.

Climate change is putting pressures on the resources we need to survive: water; agricultural land; food.

Whenever there's a big national event that brings the country together - whether it's the Olympics, a royal wedding or the 'Bake Off' final - there are inevitably a few contrarian voices speaking out against it.

A credible and effective response to climate change - which protects future generations from an unacceptable level of risk - needs the involvement of all countries.

Liberal Democrats cherish freedom of movement.

The U.K. has been at the forefront of developing the climate change policy architecture that can ensure climate action is integrated into economic decision making.
