No single person can end the climate crisis on their own, but change always starts with people who care.

The climate crisis is overwhelming. Every week, there are stories of more floods, fires, and famines happening because of our warming planet.

Luckily, we have no shortage of solutions—we just need to implement them. From tree planting and ecosystem conservation to renewable energy and plant-based diets, experts have identified over 100 solutions to the climate crisis ready for action today.

We built Wren for the millions of people who want to help, but aren’t sure where they can have a real impact.

How Wren helps you have an impact today:

1. Wren helps you fund key solutions

Make an impact by funding removals, offsets, conservation, and policy.

For those who can spare some money, funding climate solutions is the easiest way you can help. Wren makes this easy through our monthly subscription: Sign up in 5 minutes to fund the best groups doing tree planting, conservation, technology R&D, policy work, and more.

Wren member impact by month

20192020202120222023202420252526$100K$200K$300K$400K

Thousands of Wren members send millions of dollars each year to key climate solutions.

We look specifically for solutions that won’t happen without outside funding. Solutions like solar panels and electric cars are able to turn a profit without our money, but other critical solutions like rainforest protection and cutting edge technologies don’t have a path to getting investment or generating revenue. The policy work we fund also has to rely entirely on philanthropic funding, but it can be very high leverage in combatting climate change.

2. Wren helps you take action

Make an impact by making sustainable lifestyle changes and pushing for political change.

For anyone willing to put time and energy into helping with the climate crisis, it can be hard to tell what moves the needle. Wren makes this easy by suggesting actions you can take based on your lifestyle and interests.

Wren helps you take action, from buying sustainable groceries to decarbonizing your savings.

For some people, the best way to have an impact is participating in activism and being a loud voice to spread awareness on the climate crisis. But for others, the best way to get started might be cooking more plant-based or even just talking to family members about the climate crisis. Every suggestion in our Actions tool is personalized to you, and we create guides to make having an impact as easy as we can.

3. Wren helps you spread the word

Make an impact by reaching more people and growing the climate movement.

To end the climate crisis, we need collective action from hundreds of governments, thousands of businesses, and millions of regular people. While doing something on your own is a great way to get started, we need to spread the word if we want to end the climate crisis.

That’s why we build Wren to be shareable and incentivize our community to bring their loved ones into climate action. For every friend you invite with your referral link, we cover their first month on Wren and plant 10 trees when they subscribe.

Members from 100+ countries love using Wren!

“New company but seems incredibly transparent and realistic. Looked into other carbon offsets and felt they were just doing lip service [...] Wren feels real, with obvious, researchable, meaningful offsets.”

We have also invested heavily in marketing not just to grow Wren, but to grow the climate movement. We have sponsored hundreds of creators to talk about climate change, and anticipate that as we grow we’ll be raising millions of dollars to launch much needed marketing campaigns to bring awareness to climate solutions.
