Digital Planet is looking at green technology during COP26.

green technology (also green tech): Technology whose use is intended to mitigate or reverse the effects of human activity on the environment.

Firstly, we discover the green credentials of your favourite websites with the Green Web Foundation.

Can we really make the internet more environmentally friendly?

Also, we’ll be hearing about the homes in Sweden’s Stockholm that are heated using waste heat from local data centres.

And how a company in Wyoming in the US is using technology to change the way data centres are cooled, using liquid and not air, and then using this excess heat for agriculture.

The programme Digital Planet is presented by Gareth Mitchell with expert commentary from Ghislaine Boddington Studio Manager: Nigel Dix Producer: Ania Lichtarowicz

This week Discovery is asking about Global temperatures – are we too late? Even with the best efforts, it will be decades before we see any change in global temperatures through our mitigation efforts.

Meanwhile, Science In Action is asking COP26 and how to avoid a climate catastrophe NOW and also Scientists in Switzerland have developed a system that uses solar energy to extract gases such as hydrogen and carbon dioxide from the air and turn them into fuels for transport.

Green Technology in Thailand has a long way to go.

Here’s a story from 2020 about air pollution and trying to lift Thai farmers out of poverty.

As PM2.5 air pollution rose to a toxic high in Bangkok and other parts of Thailand, the public turned its attention once again to the long-tolerated practice of open field burning – to get rid of dead vegetation, rice residue, weeds, and clear the lands for the next crop cycle.

Farmers say the burnings are necessary despite the environmental toll because they are the cheapest way to clear the crops. They simply do not have much of a choice; Thai farmers often labour for little money to repay debts, selling crops for a loss.
