The Climate Question

• How can we cut the world’s shipping emissions?

  As the UN's shipping body, the International Maritime Organization, meets to decide on a pivotal levy that will tax ships for using polluting fuels, host Graihagh Jackson and BBC Climate Reporter Esme Stallard discuss whether this will be enough to cut the industry's significant carbon emissions. From the Port of Rotterdam, we find out how the industry is already trying to reduce its carbon footprint. And are alternative shipping fuels really as green as it's claimed. We dive into the issue, along with more of April's climate news. The BBC’s Climate Editor Justin Rowlatt speaks to one of COP30’s top officials, a new study on carbon-gobbling forests in China and the latest on India’s heatwave.

• Can I save money and save the planet?

  Experts say we need to be 40 per cent more energy efficient to meet our climate goals. Is that doable? And might it save us money too?It's a solution that's been called the main route to net zero: energy efficiency - or using less energy to get the same or better results. But there’s an issue – it's got an image problem as many people think it’s boring. And it is hard to get excited about the idea of better lightbulbs!But energy efficiency could save us money on our bills too - especially in a warming world, where many countries will need air conditioning just to function. So does this crucial area in the fight against climate change need a rebrand. And could it even become sexy?In a programme first broadcast in 2024, Presenter Jordan Dunbar talks to: Dr Rose Mutiso - Research Director Energy for Growth Hub Prima Madan – Director, Cooling & Energy Efficiency, International Natural Resources Defence Council, India Kofi Agyarko – Director of Renewable Energy and Energy Efficiency, Ghana Energy Commission Thomas Naadi – BBC Correspondent, GhanaProduction Team: Ben Cooper, Octavia Woodward, Brenda Brown, Simon Watts Sound Design: Tom Brignellemail: [email protected]: The speech made by President Jimmy Carter mentioned in the programme, was made in 1977 not 1974, as stated.
