Chef Jamie Oliver is now as green as his rocket salads - after creating what is thought to be the world's first carbon-neutral TV travel series.
The presenter, whose series Jamie's American Roadtrip begins on Tuesday, has "offset" the CO2 generated by the production as he travelled across the US.
Oliver's company worked closely with the Green Party and environmental experts Best Foot Forward to calculate the carbon footprint created by the programmes.
His firm, Jamie Oliver Limited (JOL), is now helping environmental projects in Asia and will also look at how to reduce emissions for further series.
Experts worked out the CO2 generated from all the flights, hotel accommodation and land travel during his team's journeys and filming across six US states for the Channel 4, which amounted to 242.6 tonnes.
JOL then worked with ClimateCare to identify suitable projects, including a scheme providing energy-efficient stoves in Cambodia, another using wind power in China and a solar power installation in India.
Oliver said: "My company is serious about helping to prevent the dangers of climate change and we recognise that, with everything we do, but especially with TV programmes like this one, we create a carbon footprint. Early on in the filming for Roadtrip, we decided that we should do something positive about the CO2 of all the flights we were making and the long car journeys we were taking.
"I felt that, as a programme-maker, it was my duty really to stand up and say that, if we're going to shoot these brilliant programmes which involve flying quite a few people everywhere, we should make a difference and help save the planet."
Best Foot Forward's managing director, Paul Cooper, said: "We are all great fans of Jamie Oliver here at Best Foot Forward. Businesses everywhere should be following his lead."

Jamie's American Roadtrip visited New York, Los Angeles, Arizona, Louisiana, Georgia and Wyoming over an eight-month shoot although there were often long gaps between locations.
