Depends on where you live and your situation. You either limit your personal CO2 or the society's CO2 or even both. Most of my suggestions will make or save you money over time.

For personal you could do these, most of these will pay themselves back within 10 years in savings.

• Swap gas stove for induction stove
• Swap a gas boiler to heat pump + electric boiler
• Buy solar panels for the roof and/or battery
• Heat pump for domestic heating for colder regions.
• Home insulation such as triple glass windows
• For hot regions getting an awning for the windows facing the sun goes a long way.
• Selling car to buy EV (CO2 neutral at 1 year, less CO2 after that)
• Buying an E-bike if you have short trips and would like to bike more (CO2 negative almost instantly if you prevent car trips)

Otherwise if you don't feel like any of those investing in solar companies or battery production companies will make it easier for them to finance expansions to their operations and maybe even make you some money along the way.

If you live in the UK or applicable countries getting in on Octopus energy co-op energy production is a good way to invest the money and reduce CO2 at the same time.

Don't forget that an easy way to limit your carbon footprint is free. Notably plastics, aluminum, steel, other metals, concrete and beef.

To limit society's footprint you can show up to city Council meetings and advocate for bike paths and public transport which really goes a long way. Showing up with a couple of buddies, making them talk and buying beer for them after in one of the most cost effective ways to stop climate change. Often city council members just need some people to back them up when proposing the CO2 negative urban planning improvements.

Stopping climate change is all about taking small steps towards the solution, asking this question on lemmy is a great start.

Pay to have someone shoot EM.

Climate change is tied to capitalism. Use it to run for office.

solar panels or something? No one is stopping climate change with $10K, I don't even think $10B would make a substantial dent.

Use it to free your own time to plant trees or contribute in another way. Spending 10k isn't gonna reduce climate change, but being able to work on the problem yourself will.

The only ways you can fight climate change in any meaningful way with 10k also involve going to prison

You're not personally responsible or able to prevent climate change. This is a societal issue that requires societal changes. Don't feel obligated to put yourself in financial trouble since the impact to your life is potentially devastating and your impact to solving climate change would be negligible. It fucking sucks but we live in a brutal capitalist system and you need to make sure you can care for yourself.

I might suggest seeing if there are local advocacy groups where you can contribute your time and, if you truly have excess wealth, help with direct financial support as needed, small contributions to things like mailing campaigns or buying a booth at a faire will help much more than blanket contributions - but, IMO, the bigger need is in effort and time.

You cannot have any significant impact with 10,000$ use it to enjoy your life. We are all doomed anyway.

Considering we live in a conflicted world where capitalism has ruined everything, I'd say donate a few thousand of it around, but also save it and just make the right choices on what you buy:

• buy zero waste, local and bio
• buy fair and repairable phones
• buy fair and ecological clothing
• etc..

So many people don't realize that every time they buy something in a store, they are casting a little capitalistic vote. We have to speak the language of what these evil sons of bitches speak, money. So I think for individuals, it mostly starts with us.

If you have any natural gas appliances in your home (like water heater, dryer, stove, oven, HVAC), transition to an electric version. Cancel your gas service.

Enjoy the money and tell yourself its not your fault.

Or alternatively, become an eco-terrorist.

Think of:

• Pipelines - buy explosives

• Certain individuals pertaining to the oil industry - buy a firearms

• Certain politicians - buy firearms

Hmm, why is there loud knocking on my door?

Buy the cheapest viable land you can and build an Earthship home out of tires, cans, bottles, and compressed Earth. Take yourself off the grid as much as possible.

I'd also suggest a career in or adjacent to alternative energy.

A gun and lots of ammo and a one way ticket to D.C. is a start, I'd say.

Fund journalism and media against fossil fuel

Fund a sterilization program for young people who have come to understand the future that humanity is hurtling towards, and who want to avoid bringing a child into such a brutally cruel future.

Both my niece and nephew have sworn off of children, as they have good educations and have fully understood just how badly humanity is fucking itself over. They’re just trying to find doctors that will do those procedures on people under 30.

10K could be leveraged toward making oil executives live in constant fear.

10k will not do much good on the grand scale of things. Once you start involving other people directly, the costs start skyrocketing. Be it if you want to bribe politicians, fund a revolution, invest into sustainable tech or just creating a bottle cap recycling programme, 10k just isnt gonna get you far enough. So focus on your own climate impact. I think the absolute best you could do for the most positive net good is to take inventory of your own carbon emissions and replace or upgrade whatever you need to lower them. Lower your heating usage by getting a heat pump instead of burning coal for example. This will depend on how low your carbon output currently is though.

Use it to fund Luigi

Solar panels and a vasectomy

I agree with the other guy, get yourself some solar panels and make yourself climate friendly, or even look at other ways you yourself an change in order to be carbon neutral

Its a drop in the ocean and I'm going to come off negative here but your up against jets, deliveries on demand from across the globe, mass meat industry and oil companies that will lobby against their destruction and in tern for mass extinction. If you really want to fight climate change move somewhere that won't see the effects, install solar learn to live off the land. An alternative if not too late become a revolutionary topple capitalism the system that allowed us to get to this point and beyond.

Give it to a group like Just Stop Oil or other direct action / sabotage focused climate activism group - they're perpetually broke and could do a lot of good with that money.

You could buy a couple of acres of land and turn it into a forest preserve. And then don't let anyone buy it to build or cut down trees / etc.

Depending on how much you care, you could even plant a sustainable forest and grow hardwood as an investment.

Invest it into a mutual fund fighting climate change. My bank has one. I guess many banks do. Some relevant terms in their fund names: fossil-free, climate, forest, sustainable agriculture.

Several funds in my bank have ESG in the name.

Aside from solar panels, as others have mentioned, I have a few other suggestions for things to get/do:

• Hydroponic garden
• Sewing machine
• Heat pump water heater
• Heat pump a/c
• Induction stovetop
• Upgrade insulation
• Compost bin
• Tools to repair common items
• Promote the use of libraries and support their growth into other communal resources
• Only buy things when needed

As others have said, there isn't much that a single individual can do against climate change, but let me explain my suggestions. Some of the most carbon intensive activities include the transportation of items like food, clothes, and other goods. To reduce your impact, you need to reduce your reliance on this carbon intensive logistics network. By growing your own food, learning to repair what you own, and learning to sew, you're making a large impact on your personal contribution to climate change. By supporting the library, you're encouraging the use of a shared pool of communal resources, which also reduces your community's climate impact.

The other items are what you can do to improve the efficiency of your house, if you own it. Induction stoves are incredibly safe and a highly efficient cooking surface. Heat pumps are crazy efficient at both heating and cooling, so slowly replacing old appliances with high efficiency options as they fail will maximize the use of what you own before it gets replaced. Compost bins and insulation certainly aren't glamorous like the other tech options, but they'll also go a long way: Landfills create an anaerobic environment, meaning food that gets thrown end up producing methane, and single family homes consume a lot of energy because heat escapes from every wall open to the air.

If you truly don't need the money, donate it to an org that's doing political advocacy.

10k of solar isn't going to make a difference in the grand scheme of things. Changing laws and regulations will.
