What can I do about climate change? 14 ways to take positive action

After the UN issued a ‘code red for humanity’ in August, many people are asking — what can I do about climate change? Quite a lot, actually

The latest report from the UN’s Intergovernmental Panel on Climate Change (IPCC) made for grim reading. It confirmed what many feared — that human activity is changing the Earth in “unprecedented” ways, and that a climate disaster would unfold without radical action to curb emissions. The report’s authors described the findings as “a code red for humanity.” 

That was the bad news. The good news is there is still time to act to keep warming to 1.5 Celsius above pre-industrial levels. Such a rise in temperature would not stop extreme weather events from becoming more severe and more common. But it would ensure that Earth is mostly habitable. 

There is no time to lose, say scientists. Radical action — the kind we’ve seen from governments during the pandemic — is urgently required. Politicians, many of whom are still approving fossil fuel projects, are being urged to change course and introduce radical legislation to slash emissions.

Ordinary people can also do their bit to mitigate warming. Listed below are 14 things you can do to shrink your carbon footprint, hold polluters to account and save yourself from climate despair.

1. Switch to a green bank 

You don’t even have to get off the sofa for this one. Yet doing something as simple as switching to a green bank can have a big impact.

“A significant amount of finance for the fossil fuel industry actually comes from the banking sector, with many UK household banking names among the worst perpetrators,” explains Adam Scott, corporate partnership manager at Friends of the Earth. “As of September 2019, nearly £150bn had been invested in fossil fuels by UK banks since the Paris agreement.”

Fortunately, upstart financial firms like Triodos and Ecology Building Society are helping put the banking sector on a more sustainable footing. Rather than using depositors’ money to fund fossil fuel projects, they bankroll green initiatives. 

“We’re not going to make significant inroads on issues such as climate change unless we rethink the role of banks in society,” says Bevis Watts, CEO of Triodos UK.

2. Change your diet

Research suggests that cutting back on meat and dairy is the single biggest thing people can do to reduce their impact on Earth.

And there appears to be growing appetite for plant-based diets. No Meat May, a charity that encourages people to quit meat in May, said that a record number of people made the pledge in 2021.

Ditto those behind Veganuary, the campaign to to go vegan in January. They reported a record uptake this year and claimed the surge in interest was driven partly by supermarkets, which helped enlist new recruits with vegan products and recipes on their websites.

“The way British supermarkets have embraced Veganuary this year is truly gamechanging,” says Veganuary’s Toni Vernelli.

3. Join an environmental group

As the saying goes, there is strength in numbers. So consider joining a campaign group to add weight to ongoing efforts to lobby policy makers to slash emissions.

Groups like Share Action are always looking for new members. The responsible investment charity buys shares in firms so its volunteers can attend board meetings, and pressure companies from inside to adopt green business models.

Power for People is another impactful campaign group. It lobbies politicians to accelerate the switch to renewable energy, and has some good advice on getting your MP to take climate action seriously.

Alternatively, why not start your own group bringing together neighbours and friends to look at how green initiatives could be better supported where you live?

 

4. Go with a green energy provider 

Switching to a green energy provider is another simple but effective way of reducing your carbon footprint. One such company is Good Energy, which buys 100 renewable electricity from independent generators and sells it on to customers.

Another is Ecotricity, which invests profits in building new sources of clean energy, with an increasing number of other energy companies also claiming to offer 100 per cent green electricity.

5. Use energy wisely 

Using energy wisely is another way to cut your carbon footprint. “Being a smarter consumer can make an awful lot of difference,” says Matthew Clayton, managing director of Thrive Renewables. “It’s not just how much energy you use, it’s when you use it.”

Setting timers for appliances to run through the night, when demand is low, or during the brightest part of the day, to utilise solar, can help. Other ways to conserve energy include switching televisions off overnight and turning the heating off when out of the house. Having a smart meter installed can help you keep tabs on energy consumption. 

 

6. Embrace active travel 

Figures suggest that 60 per cent of journeys between one and two miles long in England are made by motor vehicle. With transport accounting for a third of the UK’s emissions, substantially reducing car use — especially for short journeys — would have a dramatic impact. 

Embracing walking and cycling is good for your health, as well as the planet. For longer journeys, consider taking the train. Perversely, in the UK, this may prove more expensive than driving, which is something the government urgently needs to address. Consider investing in a rail card, which unlocks reduced fares.

7. Shun the skies 

Aviation is one of the greatest obstacles in the race to net zero. Although it accounts for just three per cent of global emissions (pre-pandemic figures), it’s one of the world’s fastest growing sources of emissions. What’s more, the sector is one of the hardest to decarbonise. 

Until battery and hydrogen planes bring us the possibility of guilt-free air travel, consider flying less — or not at all. Helping make that decision easier are new no-fly travel companies, which are making overland travel more appealing. Europe’s night trains, meanwhile, are being rebooted amid rising demand for low-carbon travel. 

8. Find out what’s going right

Amid all the gloom, there are reasons to be sanguine. Renewable energy records are being broken everywhere you look, emissions are showing signs of shrinking in some regions, and sustainable innovations are bringing myriad other benefits to society, including cleaner air, leafier cities and a lower living costs.

9. Buy local, seasonal and ideally organic  

You don’t need a climate scientist to tell you that seasonal produce, grown locally, and to a high environmental standard is better for the planet than items shipped halfway around the world from companies with murky supply chains.

If you can afford to go organic, it’s a worthwhile investment — organic farms support much more wildlife than those relying on fertilisers and pesticides. 

 

10. Grow your own 

Whether you have a windowsill or a smallholding, growing your own herbs, flowers or vegetables can be beneficial. Not just to pollinators, which can feed off the plants, but to your mental health. Sure, cultivating a garden isn’t going to absorb much carbon. But it will help you reconnect with nature, which research suggests is good for our mental health — particularly amid dire news about the climate.

11. Buy secondhand 

Manufacturing products is often a carbon intensive process, and uses up precious natural resources. Happily, options abound when it comes to buying ‘pre-loved’ goods. The Depop app is an especially popular marketplace for secondhand fashion. There’s also a burgeoning movement to borrow rather than buy appliances, through initiatives like the Library of Things. 

People are also cottoning on to the benefits of repairing and refurbishing faulty products, rather than buying new. Blazing the trail in this area is the Restart Project, which empowers people to repair electronic items. Then there’s Sojo, dubbed the ‘Deliveroo of clothing repairs’, which allows people to get their clothes altered or fixed in just a few clicks. 

 

12. Choose a sustainable pension fund

“Investing in your pension more sustainably could be 27 times more powerful than going vegan and stopping flying combined,” says Henna Shah from Make My Money Matter, a campaign group that highlights what people’s pensions are funding.

The Resolution Foundation calculates that private pensions are the largest component of household wealth in the UK, totalling over £6.1tr. And while a study suggests 68 per cent of the population want to invest in companies that put the planet alongside profit, through their pension funds they could unwittingly be backing fossil fuels or even weaponry.

“Speak to your employer and your pension provider and say, ‘actually, I want an option where I’m not investing in these things,’” advises Shah.

 

13. Switch insurers

Insurers are the second biggest investors after pension funds, so choosing an ethical insurance company will ensure your money isn’t propping up the fossil fuel sector. Naturesave, for example, donates profits to environmental projects and is campaigning for the industry to divest from fossil fuels.

 

14. Vote for parties with strong environmental policies

Elections don’t come around often. But when they do, spend some time going through the manifestos of the parties that are standing. Look at what environmental policies they support and their environmental record. Vote for the party or candidate that you think has the most credible roadmap to net zero.
