Public support for a carbon tax is growing globally, a new poll conducted for the BBC World Service suggests.

Carbon taxes put a higher price on energy that contributes the most to climate change, such as coal, oil and gas. The idea is to encourage people and businesses to use them less.

The poll in 31 countries was conducted in June and July 2021 and interviewed more than 30,000 people.

It shows 62% of people are in favour of increasing taxes on carbon-intensive energy, up from 52% in 2015. Support has grown substantially in countries that emit the most carbon, including in the US where it increased from 39% in 2015 to 56% in 2021.

People in China (83%), Vietnam (80%) and Indonesia (78%) are most in favour. While Germany and Saudi Arabia have the lowest levels of support - 51% and 50% respectively are opposed.

In the UK, 58% support the tax with more than two-thirds of people under 30 agreeing with the idea.

My name is Nel Richards, I’m a 20-year-old Cardiff University student from Swansea, South Wales.

As a BBC Young Reporter, I’ve been working on a story about building renewable energy infrastructures in the countryside villages of Wales.

In the summer of 2019, plans were announced for a solar farm on 52 acres of agricultural land at Craig Cefn Parc, five miles north of Swansea. Two months later, Swansea Council rejected the plan over concerns about a negative impact on the ecology of the area.

Dewi Lewis volunteers weekly at the nearby nature reserve where the solar farm would’ve been. He says: "The impact of this type of development on wildlife would be significant".

But Rupert Warwick, project manager for the company that proposed the solar farm, says: "There has to be a compromises in every department - developers, the government, and in local communities."

This argument is not unique to Craig Cefn Parc. With governments aiming for greener communities and more renewable structures to reduce carbon emissions, how do we balance that with impact on local ecology?

Some young activists have walked out of school to take part in today's climate demonstrations, including the one on the streets in Glasgow.

Asked about the protests, a spokesman for Prime Minister Boris Johnson says missing school for demonstrations is "extremely disruptive at a time when the pandemic has already had a huge impact" on young people's learning.

"We do understand why young people feel so strongly about climate change, and we want to see them use that passion and turn it into action," a spokesman adds, pointing to initiatives like the Climate Leaders Awards - which will see pupils recognised for their efforts to try and protect the environment.

Thousands of protesters have now crowded into George Square and speeches have begun from climate activists from around the world.

Greta Thunberg and Vanessa Nakate are both expected on stage - we'll bring you the latest as we get it.

As we wait to hear speeches from climate activists at the march in Glasgow, here's a selection of pictures from the demonstration so far.

Throughout the COP26 climate summit, we've been hearing plenty about pledges to reach net zero by 2050 - or in the case of some countries, later than that.

But what do we mean by "net zero"?

Net zero means not adding to the amount of greenhouse gases in the atmosphere.

Achieving it means reducing emissions as much as possible, as well as balancing out any that remain by removing an equivalent amount.

Greenhouse gases like carbon dioxide (CO2) are released when we burn oil, gas and coal for our homes, factories and transport. Methane is produced through farming and landfill. These gases cause global warming by trapping the sun's energy.

Meanwhile, rapid deforestation across the world means there are fewer trees and plants to absorb CO2.

Amid a flurry of announcements and speeches, the real work of the conference is going on behind the scenes.

Negotiators mush thrash out an agreement that will move the world closer to limiting the most dangerous impacts of climate change – not easy when there’s nearly 200 countries at the table.

I’ve been speaking to Grenada’s minister for climate resilience, Simon Stiell, about how things have been going so far.

He says while it’s still early days, whatever comes out of the negotiating rooms over the next few days is set to determine whether the COP is a success or not.

And while the political rhetoric seems to be softening, it remains to be seen if red lines over key issues – such as finance to help poorer countries adjust to climate change - will soften too.

“The critical issues are on ensuring 1.5 stays alive, stays within reach. We know there is a gap to close,” he says, pointing out that as a small-island developing state, finance to cope with the loss and damage caused by climate change is a key issue.

Post 2025, “where billions need to increase to trillions – where are we there?” he adds.

As we've been reporting, thousands of young activists have taken to the streets of Glasgow to call for action on climate change.

Watch the video below to see what's been happening there so far.

We are expecting to hear speeches from campaigners Greta Thunberg and Vanessa Nakete shortly, so stick with us.

Inside the conference centre, US climate envoy John Kerry has just been asked about the protesters marching through the streets of Glasgow.

A journalist from the New York Times says a lot of young people seem frustrated with what seems like slow, incremental, grinding progress, and asks what Kerry makes of that.

“I consider myself one of the frustrated," he says.

“I’m as frustrated as a lot of people. We started this journey back in 1988."

With so many young people becoming climate activists – sometimes on the world stage – more researchers are studying the question of how it affects their well-being.

Social Anthropology lecturer Bridget Bradley at the University of St Andrews completed a pilot study, external this year called Eco Worrier, Eco Warrior.

Getting involved in activism both helped and hindered activists’ feelings of distress about our climate, her findings suggest.

“Climate action often eases the sense of isolation (that comes with anxiety), but it can also lead to burn-out and increased stress levels,” she says.

She interviewed campaigners of all ages. Younger activists express more hope for the future and say they still want to travel and have children, she explains. But they also admit campaigning can make their worries worse.

Last week we also spoke to psychologist Caroline Hickman with the Climate Psychology Alliance, external.

Her top three tips for managing climate anxiety are:

• Build resilience
• Don’t switch off emotionally
• Keep perspective

Teenage climate campaigner Greta Thunberg has been spotted in the middle of the Fridays for Future climate march making its way through Glasgow.

Thunberg, 18, is due to speak later when the march reaches the city's George Square.

The demonstration is currently making its way along Argyle Street in the Finnieston area.

It is very busy, but a good atmosphere.

There are lots of young people but also plenty of parents and grandparents too, saying: "We need to do more for our children."

There are plenty of police here, with a helicoptor hovering overhead.

In most protests I have been at this week, police have out-numbered the protestors, but that is not the case here.

Graham Paisley and his 14-year-old daughter Amy are among those in Glasgow's west end for the youth march.

He says he is "here for Amy", an S4 pupil taking part in her first protest.

"If someone is going to get something done about it then it is going to be young people as we are going to have to live with it," Amy says.

Patrick Klein, a software engineer from Luxembourg who has lived in Glasgow for 20 years, is on the march with wife Julia and son Philip.

Patrick, 50, believes it is important to "send a message to politicians that they need to take action".

Philip, 10, adds: "I came here today because I want my future to be good and I want everyone else's future to be good."

Evelyn Acham, a Ugandan activist at COP26 with the Rise Up movement in Africa, says some young people have become "full-time activists" against climate change, giving up education and work.

"To the young people, this is very urgent, because we need to settle down and do other things, we need to go back to school and focus on the future," she says.

Young people continue to take to the streets across the world because "we do not have a choice", she adds.

Actress Emma Watson, best known for playing Hermione Granger in the Harry Potter series, says she has hidden books about climate activism around Glasgow.

She says the COP Book Fairies initiative will see some 300 books hidden nationwide for people to find and get their hands on.

Watson previously linked up with the Book Fairies in 2017 on International Women's Day.

The initiative encourages people around the world to leave books in public spaces for others to enjoy.

It's the sixth day of the climate conference, with world leaders attending for two days and negotiations between countries continuing.

We've just heard US climate envoy John Kerry say "genuine progress" is being made at COP26 - so what have been the headline announcements?

• The climate summit's first major deal saw more than 100 world leaders promise to end and reverse deforestation by 2030

• More than 40 countries have committed to shift away from coal, in pledges made at the COP26 climate summit
• UK chancellor Rishi Sunak set out plans to encourage large firms to work towards the UK's 2050 net-zero target
• South Africa is set to receive $8.5bn (£6.2bn) to help end its reliance on coal in a deal announced at the COP26 climate summit

We've been reporting all day on the protests on the streets of Glasgow – but inside the summit, negotiations between nations continue.

In a speech currently taking place, US climate envoy John Kerry says there is "genuine progress" being made at the conference.

"There is a greater sense of urgency at this COP, there is a greater sense of focus," he says.

Kerry adds that he's never seen as much "real money" being put on the table so early into one of these climate summits, even if there are some legitimate "question marks" about some of the money.

He says the majority of the G20 – the 19 biggest economies in the world, plus the EU – have "real plans" to limit global average temperature rises to 1.5C, if all aspects of the plans are pursued.

"That's a game-changer. Way beyond what many people thought was possible," he says.

My name is Donald Matheson. I’m 21 and I’m a filmmaker and storyteller of Kenyan and Scottish descent.

As a person of colour in the UK who grew up in relatively rural and green areas it’s a been a bit disheartening to see so few people “who look like me” at recent climate change and environmental rallies. Climate change is everyone’s problem, and yet not everyone in our society seems to be equally engaged.

But taking it back a step, does the onus actually belong on people of colour for not showing as much of an interest?

With over 90% of black and minority ethnic (BAME) people in the UK living in urban environments and only 59% of people in the BAME community (compared to 80% of the population as a whole) agreeing that Scotland’s wildlife makes an important contribution to the economy, it is clear much of our community hasn’t had the opportunity to build a meaningful relationship with the main parts of our environment being destroyed by climate change.

Well, as someone’s who’s learned to love nature through living rurally and having the chance to go camping, outdoor swimming and mountain biking, I strongly believe we need to start by making the very thing we are trying to save more accessible to all.

With the climate march under way in Glasgow, activists have been speaking about their reasons for being there.

Charlie O'Rourke, 14, says world leaders at COP26 need to put profit aside and "listen to the planet".

His mother Cairsty O'Rourke, who is also there with her daughter Edith, says: "I'm basically here for my children and for the generations to come to just show that something has to happen and it has to happen very quickly in order to change the trajectory that we're going on."

She says "big words" have been spoken at COP26 but governments around the world "have to be made to follow through on the promises that they make".

"It is absolutely pivotal to the future, to us as a human race. And we don't have that much time."

Fourteen-year-old Finlay Pringle, travelled to Glasgow from Ullapool, Scottish Highlands, with his father.

He says young people "shouldn't think twice" about protesting for the things they care about, saying: "If there's something that you love and you want to protect it, then you should do that, don't think twice about it".

With the climate summit continuing in Glasgow, the BBC has been speaking to young people around the world affected by climate change. Nasieku Lesiamito is a 25-year-old pastoralist from Louwabene, Kenya who is part of a community that has had their lives upended due to drought conditions.

She says: "I have been affected by climate change because I had to move here since where I live was affected. I come from a place called Louwabene and I have come here, Maralal Kuroto, in search of grass and water for my goats and cows.

"As women, we have really suffered because of the lack of water. We wake up in the morning at 07:00 to look for water and we come back in the evening. At times when you get back, you find that the goats and calves have strayed.

"As the Lowabene community, we came together and the elders encouraged us to contribute some money towards drilling a borehole. But in the midst of raising the money for the borehole, the drought became worse and everyone left to different places to look for water.

"There are some children who dropped out of school since the drought struck. The parents had left so the children could not be left behind alone.

"If we were to get water and pasture, we would be settled and our children would go back to school. As women we will start doing business, we have a small centre called Lekuru where we can go and start doing trading."
