Arnold Schwarzenegger is the former governor of California and one of America's most influential green voices. He's also one of the biggest movie stars in the world and a big fan of the innovators, activists and entrepreneurs featured in the previous 39 episodes of this series. In this final programme, the Terminator star discusses his favourite ideas from the series with Tom Heap and looks forward to the crucial climate change talks in Glasgow in November.
Apple has always maintained it knows what’s best for its customers. But now governments and developers are trying to change the way Apple runs its highly profitable iPhone App Store. What happens if Apple can no longer hold its tight grip on the iPhone and the way we interact with the world?
Bennington. Spring, 1983-Spring, 1985. Bret lives The Rules of Attraction, then sells Less Than Zero. Bret befriends David Lipsky, then be-enemies David Lipsky.
Tom Heap discovers fresh ways to quantify greenhouse gas emissions with help from satellites, artificial intelligence and former US Vice President Al Gore.
Emissions data from companies and countries can be inaccurate, incomplete or sometimes just plain deceitful. The team at Climate TRACE, led by Al Gore, have devised innovative ways to calculate accurate emissions data from power stations, factories, ships and even planes. That data can be used to reveal unexpected sources of carbon dioxide and methane and to provide independent figures for international negotiations on climate change.

Ever thought about the carbon cost of a packet of crisps? At CCM Technologies they think of little else. Their revolutionary fertiliser offers a big step to carbon-free snacking.
Waste from crisp factories or from sewage treatment works can be routed and treated to form the basic building blocks of new fertilisers that can be spread on the ground to grow a new harvest of potatoes- or any other crop we need. The system avoids waste and takes a big cut out of the carbon emissions of traditional fertiliser production. Tom Heap tours the CCM fertiliser plant on the outskirts of Birmingham and discusses the carbon benefits with Dr Tamsin Edwards of King's College London.

Wind energy is vital in the battle against climate change, but can we make improvements to harness more from them?
Tom Heap visits Kelburn windfarm in North Ayrshire to discuss whether 'wakesteering' - reorientating the turbines could see them harness more power collectively. Meanwhile some potential sites are refused or restricted due to the damage caused to wildlife. Hubert Lagrange talks about his childhood obsession with bats which are often killed by the pressure around turbine blades.
He's worked to develop a system to sense bat and bird activity and allow the turbines to operate longer through a refined system.
Dr Tamsin Edwards discusses how much more potential there is and how much carbon this could save.

Snap! The trap-jaw ant’s amazing jaws can move faster than a speeding bullet, snapping shut at a top speed of 230km per hour. When the ant bites down, the force is so great that it launches the insect high into the air. Their powerful spring mechanism is being copied by scientists and may help move a new type of mini robot, which one day could be deployed in situations too dangerous for humans to enter – like fires or earthquake zones.

Back in the early 2000s, file sharing services like Napster devastated the music industry. Steve Jobs threw it a lifeline with the iTunes Store, offering people an easy way to download songs legally. That saved the music industry and made Apple a dominant player in the music biz...for a time. Twenty years later, the television industry is going through a similar upheaval, but this time, Apple isn’t leading the way. What happened to Apple’s golden touch?
Batteries are powering the electric car revolution, but can we make them longer lasting, faster charging and smaller and lighter? Beyond electric cars and other vehicles, the more applications means more renewable energy can be stored and used, driving us away from fossil fuels. Tom Heap visits UKBIC - the UK Battery Industrialisation Centre in Coventry - a vast facility to develop better batteries. He dons full protective gear to see some of the processes involved in making batteries and testing new chemistries and engineering. He speaks to Isobel Sheldon from British Volt about the goals and potential that could be realised by improving batteries and climate scientist Dr Tamsin Edwards assesses how much carbon dioxide this could potentially save.
