How tech can help to tackle climate change

There's no denying that climate change is one of the biggest threats to our way of living. Can technology help to save the world?

Climate change is one of the most serious issues we face today. According to the World Meteorological Organization (WMO), we've experienced the 20 warmest years over the past two decades. The effects are tremendous, including rising oceans, melting polar ice caps, famine and extreme weather. But these organisations believe that they can solve climate change using technology.

Tackling food waste

If there's one issue having a significant impact on the environment, it's food waste. Research shows that one third of food is wasted every year, weighing 1.3 billion tonnes and worth $1 trillion in retail value. This is despite the fact that over 820 million people across the globe are starving.

Jamie Crummie, co-founder at food waste app Too Good To Go UK, says: "Worldwide, a third of food produced gets wasted. When food goes to landfill, it creates methane - a greenhouse gas 27 times more potent than carbon dioxide. And that's not the only thing; it takes about five brimming bathtubs of water to produce a carton of six eggs."

"We need to learn to cherish food, realising that - just like the land that was set aside to grow it, or the water that was used to sustain it - it's far too precious to waste. The data and insights we get from technology let us tackle the issue with a level of nuance - and on a scale - that was unprecedented until now."

Looking to solve this issue, Too Good To Go has developed a platform for buying unsold food from restaurants, cafes, shops and bakeries before it's thrown out. Since launching in 2016, the app has been downloaded by over 22 million users and helped to save 35 million meals globally.

Crummie adds: "Not only do apps like Too Good To Go enable people to stop perfectly edible food from being wasted, but they're a way of putting the topic of food waste at the forefront of people's minds. By harnessing technology and tackling the issue at all levels of the supply chain, we can drive the food waste movement forward, challenging societal behaviours as we go."
