The Paris Climate agreements come into force today, and the bosses of seven big oil companies gathered in London to sign an agreement to work together to cut emissions.
The group – including BP, Norway’s Statoil, and the Saudi oil company Aramco – accounts for a fifth of world oil supply, and they will create a $1bn fund to boost their climate change efforts.
They will research renewable energy, share technology between member companies and reduce leakages of methane from oil and gas plants – a big cause of global warming.
Three of their chief executives – Bob Dudley of BP, Patrick Pouyanne of Statoil and Eldar Saetre of Statoil – met with the BBC’s business editor Simon Jack after the signing ceremony to discuss their plans.
He began by asking them why they were signing their agreement today.
A self-drive electric delivery van, that could be on UK streets next year, has been unveiled at the Wired 2016 conference in London.
The vehicle's stripped-back design and lightweight materials mean it can be assembled by one person in four hours, the firm behind it claims.
The vehicles will be "autonomous-ready", for when self-drive legislation is in place, the firm said.
The government wants to see self-drive cars on the roads by 2020.

Recurrent attacks up to 3 November flooded the cable link with data, making net access intermittent.
Researchers said the attacks showed hackers trying different ways to use massive networks of hijacked machines to overwhelm high-value targets.
Experts said Liberia was attacked by the same group that caused web-wide disruption on 21 October.

Long-standing tensions between Saudi Arabia and Iran resurfaced at an Opec meeting last week, with with the Saudis saying they could raise oil output steeply to bring prices down if Iran refuses to limit its supply, the Reuters news agency reports.
"The Saudis have threatened to raise their production to 11 million barrels per day and even 12 million barrels per day, bringing oil prices down, and to withdraw from the meeting," a source told Reuters.
Saudi Arabia has increased output since 2014 to record highs of around 10.5 million to 10.7 million barrels per day.

Marks and Spencer is expected to announce the closure of a number of stores next week as part of plans to turnaround the business.
A shake up of its international operations is also on the cards.
The new boss, Steve Rowe, will update the city on the retailer's latest trading performance on Tuesday as well as set out his latest thinking on how to revive M&S's fortunes.
Smaller branches in weaker high streets are understood to bear the brunt of the cuts, which would happen over the course of a few years.
According to SKY News, they would number in the "low dozens" while other stores would see space reallocated from clothing to its more successful food operations.
A spokesperson for Marks and Spencer said it didn't comment on rumours or speculation.

There are two main reasons why the price of petrol and diesel has been going up.
First of all, the cost of crude oil has risen sharply since the start of the year.
In January, a barrel of Brent crude was trading below $34 per barrel. By early October the price had risen to nearly $54.
If the price of oil rises, so too does the cost of products made from it - although the fact that much of the price we pay at the pump is actually tax means the impact, in percentage terms, is lower than it would otherwise be.
Secondly, there's the steep fall in the value of the pound since the summer.
Oil is priced in dollars on international markets, so if the pound falls against the dollar, the amount we pay for oil-based products is going to rise.
In early October the pound fell sharply and the oil price rallied - so it's really no surprise fuel costs rose.
However, in recent days the cost of crude has fallen back somewhat, and the pound has rallied. If those trends continue, and it's a big if, there might be better news for drivers up ahead.
Taco Bell, a unit of fast food giant Yum Brands, has said it will increase the number of its outlets in the US to 9,000 and create 100,000 jobs by the end of 2022, as part of a push to reach $15bn in sales.
Taco Bell, which already has about 7,000 restaurants in the US, had revenues of about $2bn in 2015.
The Mexican fast food chain employs 40,000 people in US company-owned stores.
Taco Bell's US expansion follows plans to grow its international store base to 1,000 restaurants by 2022.
The company, which has 300 restaurants in international markets, opened its first outlet in Brazil in September.
The planned hiring and expansion efforts come after Yum Brands' spinoff of its operations in China, the company's top profit generator, into a separate unit called Yum China earlier this week.
Bombardier's Global 7000 aircraft has had its first test flight over Toronto, the Reuters news agency reports.
The test flight is a milestone for the long-range business jet, which is considered key to the growth of the company's corporate plane division.
The new luxury jet is scheduled to enter service in 2018 after being delayed for two years.
Pictured is US actor Matthew McConaughey who attended a Global 7000 showcase in Beverly Hills in May.
Former Top Gear presenter Quentin Willson, fellow Fair Fuel campaigner Howard Cox, and Conservative MP Charlie Elphicke have set up a petition calling for MPs to debate the creation of an independent petrol-pricing regulator.
Mr Willson told the BBC Business Live page that vehicle fuel was one of the very few products UK consumers buy in quantity with little regulation on pricing.
Fuel prices seem to go up overnight when crude oil prices rise, but take "weeks and weeks" to come down, he said. The way fuel prices work appears "obscure and impenetrable", he added.
Mr Willson said that the "excuse" that crude oil is priced in dollars, which means fluctuations in the sterling/dollar exchange rate have an impact on petrol prices, doesn't explain the time lag in petrol prices falling.
"It's just a simple, obvious request," he added. "All we want is transparency."
As if Samsung didn't have enough on its plate.
Fresh from dealing with its fiery Galaxy Note 7 smartphones, the South Korean company has now had to recall 2.8 million top-loading washing machines in the US.
The reason? The top of the machine can detach itself from the machine and cause injury, which so far includes someone whose jaw was broken.
Samsung has received nine reports of injuries and 733 notifications of excessive vibration in the washing machines or a detaching top.
The recall involves 34 models of top-load washing machines made between March 2011 and November 2016.
Who knew doing a wash could be so dangerous?

A group of human rights experts from the United Nations is urging the Brazilian authorities to address unresolved issues a year on after the collapse of a mining dam.
Saturday will mark the first anniversary of the incident in the mines operated by Samarco, Vale and BHP Billiton that left 19 people dead and a track of pollution by mud.
The panel of experts says many of the 6 million people affected by the tragedy are still suffering with various issues, including a potential water contamination of the River Doce.
It wants the government to ensure that minimal safety levels are guaranteed for the water being consumed.
Last month, prosecutors filed homicide charge against 21 people linked to the firms.
Samarco, Vale and BHP Billiton have set up an institute and agreed to pay compensation and reconstruction of communities for a period of 10 years.
German railways giant Deutsche Bahn has shelved plans for a stock market flotation of Arriva after Britain's vote to leave the European Union, the company's boss has said.
State-owned Deutsche Bahn had planned to float up to 45% of Arriva on the London Stock Exchange, as well as part of its logistics unit Schenker.
But chief executive Ruediger Grube said he will inform directors in December that he cannot recommend the initial public offering.
Mr Grube said that "unfortunately, the world has changed fundamentally as a result of Brexit," pointing to the pound's collapse following the June 23 referendum vote.
He added that, if the share sale went ahead, "we would be throwing money out of the window, and acting that way would be foolish."
Arriva is Deutsche Bahn's international arm and operates a number of Britain's train and bus services.
Eurostar has said passenger numbers fell 10% year on year in the third quarter, while sales were down 8%.
It blamed the Nice terror attack in July for dampening demand, but said numbers were rebounding - particularly because of the weaker pound which had made the UK a more appealing destination.
The operator also said it was pressing ahead with plans for direct rail services between London and Amsterdam. Journeys between the cities are due to begin at the end of 2017.
A new £400m deepwater port opens in Liverpool today. The owners Peel Ports want to attract the world's biggest cargo ships away from southern UK ports and create a new transatlantic hub for UK shipping.

US employers continued their strong rate of hiring in October while increasing wages.
Non farm payrolls were up 161,000 in the month while average hourly earnings rose 0.4%. The unemployment rate edged down to 4.9%.
Observers suggested the figures would have little bearing on the US election, but added weight to the expectation of an interest rate hike in December.
BMW beat expectations today with a record net profit for the quarter to September.
The German carmaker made earnings of €1.8bn, up 15% year-on-year, having sold a record 583,000 vehicles in the period.
Sales grew to €23.4bn euros, with its BMW, Mini and Rolls-Royce divisions all doing well.
The business added it would continue to invest in research and development in areas like electric and driverless cars.
Oil is headed for its biggest weekly loss in almost 10 months, after Opec failed to agree on production quotas for member countries last week - a preliminary step toward finalising an output freeze.
Brent crude was trading at around $46 a barrel in the early afternoon - down from just under $51 seven days ago.
Harry Tchilinguirian, head of commodity markets strategy at BNP Paribas SA, told Bloomberg: “Some countries like Iraq are already taking an exit from participating in cuts. What Opec may ultimately deliver risks falling short of what is required.”
Inventor James Dyson is to open his own higher education college to tackle skills shortages in UK engineering.
The Dyson Institute of Technology, based at Dyson’s research and development campus in Wiltshire, will offer engineering degrees alongside "hands-on experience" developing Dyson products. Students will also earn a salary as they study.
Mr Dyson said: “I know there are many people out there who are as obsessive about engineering as I am - questioning every aspect of a product, how it works, and how it can be better. Therefore why not get stuck into an engineering job straight from school?”
The FTSE 100 has fallen still further - a short while ago it was down 1.48% at 6,690.2.
As in Asia, the prospect of a Donald Trump victory in the US presidential elections were blamed for the falls.
