We all need to do more to combat climate change, and we all have the power to do so through our everyday decisions



Take the Pledge

The recently released report by the Intergovernmental Panel on Climate Change warns that the world has just 12 years before we reach an irreversible tipping point of climate disaster.  In order to avoid warming the planet by more than 1.5 degrees Celsius and to stop the most catastrophic effects of climate change, we need "rapid, far-reaching and unprecedented changes in all aspects of society."

With the way things are currently going, you may be feeling hopeless and helpless about the fate of our world, but you are not alone.  In fact, millions of people want to act to ensure a liveable world free from climate change but don't know what to do about it.

The truth is YOU have the power to fight climate change with everything decision you make.  Things like taking short showers and recycling are good steps, but these alone are not enough.  There are much more important and impactful actions that each of us can and must take.  We all need to do everything in our power to fix this problem.

We are building an alliance of millions of people who are committed to doing as much as possible to stop climate change.  The more people who pledge to take the following 5 most impactful actions, the more our collective impact and the better our world's future will be.  This is not about being perfect, but about each of us maximizing our personal impact in the fight against climate change to ensure a liveable planet for all people.  

Join us and take the pledge to go "all in" to save the world!

I pledge to:

1. Have at most one biological child, or if I already have biological children to have no more.

Of course, multiple births (twins, triplets, etc.) are exceptions, as are children who don't live past childhood.  Adopting and fostering children is highly encouraged for anyone who wants more children.

Why is this important?

Because adding another human being to the world means that that person will consume resources and create greenhouse gas emissions throughout their whole life!  For an average American who lives until age 80, having one fewer child prevents almost 20 times more carbon emissions than driving a hybrid, driving less, recycling, using energy efficient appliances, windows, and light bulbs combined. 

This is the single most impactful action one can make to combat climate change.

How do I put this action into practice?

  • Use contraception and birth control methods to prevent pregnancies.

  • Adopt or foster instead of having biological children.

2. Eat a diet that is centered around plant foods while avoiding meat (especially beef) and animal products.

Why is this important?

Animal agriculture (meat, seafood, dairy, eggs) is an extremely inefficient way of creating food.  This is because livestock, like all animals, need to eat while they are alive and the amount of calories you get from eating meat is much less than all the calories and and resources that went to feeding that animal during its lifetime.  If all the grain currently fed to livestock in the US was instead given directly for people to eat, we could feed around 800 million people, more than double the population of the US.  Red meat, such as beef and lamb, is the most inefficient and is responsible for up to 40 times as many greenhouse gas emissions as vegetables and grains, while livestock and their byproducts account for 51% of all worldwide greenhouse gas emissions.  A person following a vegan diet (no animal products) produces the equivalent of 50% less carbon dioxide, uses 1/11 the oil, 1/13th the water, and 1/18th the land compared to a meat-lover as a result of the food they eat.  Additionally, cattle ranching is the primary source of rainforest deforestation, and animal agriculture is the leading cause of species extinction, ocean dead zones, water pollution, and habitat destruction. 


Not only is it better for the environment, but you will likely be improving your own health!  Amazingly, eating a diet centered around whole plant foods can also prevent many of our leading causes of death, including heart disease, breast, prostate, and colon cancers, and type 2 diabetes!

  • Don't let the myths associated with vegetarian and vegan diets stop you!  Read this article debunking the common myths.

  • You don't have to turn vegetarian or vegan overnight (although you certainly can!)  Any reduction in eating animal products, even if it is just cutting out beef or going meatless once a week, will have an impact, but the more plant-based your diet the more impact you will have.

3. Do more with less and significantly reduce the amount of food, water, energy, materials, and possessions that I use and waste.

Why is this important?

Most things you use, whether they are materials possessions, food, or energy (electricity or fuel), have a carbon footprint, meaning fossil fuels have been burned in order to make and bring these things to you so that you can use them.  You can reduce the use and demand for burning fossil fuels by using less things and by choosing more efficient, reusable, and longer lasting things.

Another reason why this is important is that our use of finite natural resources is simply unsustainable.  If all 7 billion-plus people in the world lived like the average American, we would need 4.1 earths-worth of land and resources.  If we all lived like the average citizen of the United Arab Emirates, we would need 5.4 earths, 2.5 for France, 1.9 for Nepal, 1.4 for Costa Rica, 1.1 for China, but less than one for Uganda, India, and Bangladesh.

How do I put this action into practice?

  • For everything you use, think about the Waste Pyramid.  Ask yourself "Do I really need this?  Does this thing really have value to me?"  If you do really need it, think "Can I do with less of this?  Can I find a version of this that uses less materials and resources in its creation and journey to get to me, and/or has a longer usable life, and/or has already been used before?"  When you are about to toss something in the trash, think "Is this still usable?  Can I make it still be useful in some other way to me or to somebody else?  Can this be recycled and the materials reused for another purpose?"

  • Buy less and live with fewer possessions and stuff

  • Buy used things whenever possible

  • Give your things a second life by selling, donating, or simply giving them away for free

  • Use things longer by repairing them when broken, buying durable and dependable things, and using them only until they simply can't be used any more.

  • Use reusable items instead of disposable ones

  • Buy local food and goods whenever possible

  • Use less, and be more efficient with energy (electricity and fuel) and use clean renewable sources whenever possible

  • Limit flying to only when necessary, and when you do buy carbon offsets if possible

  • Reduce food waste

4. Divest my money from companies and institutions that are contributing to the problem and invest instead in ones that are helping to solve it.

Why is this important?

If you have money in a bank or in any type of investment, odds are that some of your money is being used to finance the burning of fossil fuels and other businesses that are contributing to the problem of climate change.  Instead, make sure your money is working to fund the solutions to climate change. 

Learn more about why this is important:

How do I put this action into practice?

  • Divest bank accounts and investments (if you have them) from banks and companies that fund fossil fuels and instead invest in those that are supporting and creating solutions to climate change, such as renewable energy, energy efficiency, and plant-based agriculture.

5. Encourage others, including family, friends, co-workers, neighbors, employers, companies, politicians, governments, schools, and organizations to do more to combat climate change.

Why is this important?

One person can't stop climate change on their own.  We need to multiply our personal impact by helping others to increase theirs.  Importantly, large steps towards solving this problem can come from policy changes in governments (at the city, state, national, and international levels), companies, and institutions, and these are necessary in order to create enough reductions in global greenhouse gas emissions.

How do I put this action into practice?

  • Demand to hear politicians' views on how they will address the problem of climate change.  Call and email them, visit their offices and show up to their public appearances to demand they work towards tackling climate change.  Find your elected officials and how to contact them (US only)

  • Register to vote, and then vote for politicians that pledge to tackle climate change.  Politicians only listen to the views of voters, not non-voters.  

  • Join non-violent protests, events, strikes, campaigns, demonstrations, and direct actions to demand large-scale action on climate change by governments and companies.

  • Volunteer for organizations that are working on spreading solutions to climate change.

  • Encourage companies to sell more sustainable products and to do more to combat climate change, thank them when they do, and encourage them to go even further.

  • Demand institutions divest, desponsor, and defund fossil fuels  and other industries that are contributing to the problem, such as animal agriculture.

  • Encourage others to take this pledge and these 5 most impactful actions.
