What Can I Do to Prevent Climate Change

Ten simple means to act on climate change

We know that climate modify is happening – only there are plenty of things individuals tin practise to assistance mitigate it. Here's your handy guide to the most effective strategies.

The route towards that transition includes daily decisions inside your reach – like driving and flight less, switching to a 'green' energy provider and changing what you lot consume and buy.

Of course, information technology's truthful that climate change won't be solved past your buying or driving habits alone – although many experts concord these are of import, and can influence others to brand changes also (more than on that after). Other changes are needed that can only exist made on a bigger, organisation-wide basis – like revamping our subsidy system for the energy and food industries, which continue to advantage fossil fuels, or setting new rules and incentives for sectors like farming, deforestation and waste material management.

One good example of the importance of this regards refrigerants. An advocacy group of researchers, business organisation-people and NGOs called Drawdown found that getting rid of HFCs (chemicals used in fridges and air conditioning)  was the number-ane most effective policy to reduce emissions. That'south because they are up to 9,000 more warming for the atmosphere than CO2. The good news is that we have made global progress on this, and two years ago 170 countries agreed to start phasing out HFCs in 2019.

This is important considering we need "unprecedented changes in all aspects of lodge to deal with climatic change, says the IPCC report. "Anybody is going to take to be involved," says Debra Robert, co-chair of the Intergovernmental Console on Climate Change (IPCC), the group tasked with the report.

2. Changing how industries are run or subsidised doesn't sound like anything I tin can influence... can I?

You can. Individuals need to practise their rights both as citizens and as consumers, Robert and other experts say, putting pressure on their governments and on companies to brand the system-wide changes that are needed.

Another manner, increasingly undertaken by universities, faith groups and recently even at a countrywide level, is to 'divest' funds out of polluting activities – such every bit avoiding stocks in fossil fuels, or banks that invest in high-emission industries. Past getting rid of financial instruments related to the fossil fuel industry, organisations tin can both accept climate action and reap economic benefits.

3. Other than that, what's the all-time daily activity I can take?

I 2022 study co-authored by Lund University's Nicholas ranked 148 individual actions on climate modify co-ordinate to their impact. Going motorcar-gratuitous was the number-i virtually constructive activity an private could accept (except non having kids – but more on that on that afterwards). Cars are more polluting compared to other means of transportation like walking, biking or using public transport.

In industrialised countries such every bit European nations, getting rid of your car tin can reduce two.5 tonnes of CO2 – about 1-4th of the average yearly emissions (9.2 tonnes) contributed by each person in developed countries of the Arrangement for Economic Co-operation and Development (OECD).

"We should choose more efficient vehicles and, whenever possible, switch directly to electric vehicles," says Maria Virginia Vilarino, co-author of the mitigation chapter in the IPCC's latest report.

four. But isn't renewable free energy extremely expensive?

Actually, renewables similar wind and solar are becoming increasingly inexpensive beyond the world (although final costs are subject to local circumstances). The latest report from the International Renewable Energy Bureau (Irena) found that several of the most commonly used renewables, like solar, geothermal, bioenergy, hydropower and onshore wind, will be on par with or cheaper than fossil fuels by 2020. Some are already more cost-effective.

The meat manufacture contributes to global warming in iii major means. Firstly, cows' burping from processing food releases lots of methyl hydride, a greenhouse gas. Secondly, we feed them with other potential sources of food, like maize and soy, which makes for a very inefficient procedure. And finally, they also require lots of water, fertilisers that tin release greenhouse gases, and enough of land – some of which come up from cleared forests, another source of carbon emissions.

International ship, including maritime and air shipping, too has an impact. Groceries shipped from Chile and Australia to Europe, or the other way effectually, have more 'food miles' and unremarkably a college footprint than local produce. Simply this is not always the case, as some countries grow out-of-season crops in free energy-intensive greenhouses – so the best approach is to eat nutrient that is both locally grown and seasonal. Even then, eating vegetarian still beats only purchasing local.

8. Should I think nigh how many children I have (or don't have)?

Nicholas's study concluded that having fewer children is the best way to reduce your contribution to climate change, with almost 60 tonnes of CO2 avoided per twelvemonth. But this upshot has been contentious – and information technology leads to other questions.

One is whether you are responsible for children's climate emissions, and the other is where are these babies born.

If you are responsible for your kids' emissions, are your parents responsible for yours? And if you are non, how should we consider the fact that more than people volition likely have more carbon emissions? We also could enquire whether having offspring is a human right beyond questioning. And we could ask if having children is necessarily a bad thing for solving climate change: our challenges may mean nosotros will need more problem-solvers in future generations, not fewer.

Those are hard, philosophical questions – and we're not going to attempt to answer them here.

What we do know is that no two people accept the same emissions. Although the average human being releases around 5 tonnes of CO2 per year, each state has very different circumstances: adult nations like the US and South korea have college national averages (16.5 tonnes and eleven.v tonnes per person, respectively) than developing countries like Pakistan and Philippines (around ane tonne each). Even within national borders, richer people have higher emissions than people with less admission to goods and services. And then if you choose to accept this question into account, you lot have to remember that information technology'south not just about how many children you have – it's where (and who) yous are.

9. Just if I eat less meat or have fewer flights, that's just me – how much of a deviation can that actually brand?

Actually, it'south not simply yous. Social scientists take found that when i person makes a sustainability-oriented decision, other people do also.

Here are four examples:

• Patrons at a US cafe who were told that 30% of Americans had started eating less meat were twice as likely to order a meatless dejeuner.
• An online survey showed that of the respondents who know someone who had given up flying because of climate change, one-half of them said they flew less every bit a event.
• In California, households were more likely to install solar panels in neighbourhoods that already have them.
• Community organisers trying to get people to install solar panels were 62% more successful in their efforts if they had panels in their firm likewise.

Social scientists believe this occurs because nosotros constantly evaluate what our peers are doing and we adjust our beliefs and actions appropriately. When people see their neighbours taking ecology action, similar conserving energy, they infer that people similar them too value sustainability and feel more compelled to act.

10. What if I just can't avoid that flight, or cutting down on driving?

If you lot simply can't make every alter that'southward needed, consider offsetting your emissions with a trusted green projection – not a 'get out of jail gratuitous card', but another resource in your toolbox to compensate that unavoidable flight or car trip. The UN Climate Convention keeps a portfolio of dozens of projects around the world you lot can contribute to. To notice out how many emissions you lot demand to 'buy' dorsum, yous can use its handy carbon footprint figurer.

Whether yous are a coffee farmer in Republic of colombia or a homeowner in California, climatic change will have an impact on your life. But the opposite is also true: your deportment will influence the planet for the coming decades – for better or for worse.
