This is the best way I’ve found to try to do my part in this demanding world. We need initiatives like this one. The follow ups give me hope and their mission is beautiful. This is a wonderful and worthy effort.
I'm actually really impressed with Wren. I'm a born skeptic and have been especially skeptical of anything related to ESG since it's so easy to exploit people's good intentions and poor training for personal gain, but Wren is a truly stand-out project that strikes the perfect balance of transparency and private development. (For example, they tell you all about the projects they're investing in, but the process of figuring out what the org should care about and how to support those ideals is less public (although probably not secret).) This provides you with all the information you might want without being noisy. Additionally, they're quite scientific in their assessment and selection of portfolio projects.This gives me a lot of confidence that my money is not just getting dumped into someone's Lambo. I've been with Wren for almost 2 years now and I can safely and emphatically say go for it.
Wren updates me on projects and impacts regarding co2 reductions. They work smarter on terms of abating the most co2 for the buck. And they are transparent in terms of administration costs and targets.
Project updates give a lot of insight about Wren activities
Wren is great at providing regular updates to show where my money is being spent. They have an intuitive dashboard to help visualize the impact I'm having and even though my government sadly takes plenty of harmful actions against the environment, I can rest easy knowing that I'm at least contributing to a better planet through the help of Wren.
I love Wren. They deeply research the projects to be truly effective at carbon offset and improving our chances of continuing to live on this planet. I cannot say enough about it.
Wren is exactly the platform I was looking for. I've been looking for a platform that allows me to donate to activities that mitigate greenhouse gas emissions over a broad category of projects (including lobbying, carbon capture, nature protection, emissions reductions, etc). You can track where you money goes. You can easily modify your donation amounts and focus. The only downside is the relatively large fraction of donations they keep for their operations. I guess this is the price to pay for a great web interface and all the research and coordination required to find new projects.
Easy to setup and the project updates are frequent and interesting.
We believe in you, don't stop.
This site makes it easy to offset your carbon footprint. They give you regular updates on the portfolio which is a good way to learn more about ways to offset carbon.
They're great! I feel bad for not being out there planting trees and stuff myself, but I'm glad I can do my part and help fund bigger projects I wouldn't be able to do myself!
The project by its own is grat. The updates come regularly and it really gifs you a sense of impact. My only critic might be that you don’t pay for one specific project but rather just for Wren with all its projects. This means you can’t help guide the direction to where Wren evolves.
Transparency and clear communication about offsetting, and very easy user experience!
I pay ~9 euros per month because i have a very small carbon foodprint. And it is always nice to get updates from the projects around the world :) happy to be part of wren :)
I made the carbon foot print test with my future house, I will have 2025. All the test, I was not asked about the energy standard of the house, the location and most important, that it will have 44 kW photovoltaic and 140 kWh of sodium batteries for a demand oriented grid feed in. In Salzburg, the system will have 35,000 kWh yearly yield. 8.000 kWh will be my yearly consumption including charging an electric car for 25,000 km a year. Alone the 27,000 kWh yearly grid feed in are normally calculated with 700 g/kWh, makes 18.9 tons CO2 emissions avoided.
Wren is just absolutely amazing, and I cannot overstate my enthusiasm for them. They not only are tackling climate change with a multidisciplinary approach for the betterment of our environment, but they are super clear and informative about their efforts, too. I love how they provide the details of where your funds are going and how well designed their whole website is. This is really amazing work and I'm so grateful to be a part of it!
Wren pays organizations to reduce global warming. Naturally, donors want to know how their money is being used, and Wren is very transparent about that. A good amount of the money is spent on marketing but that's because Wren needs to get their story out to grow their system. And it seems to be working: their expenditures are increasing year by year.
I was turned on to Wren by a friend after expressing interest in purchasing carbon offsets to compensate for additional emissions from life/lifestyle changes. After reading more about their approach, everything about the sign-up experience seemed just right. I like their style and the periodic updates. Even some good, well-meaning charities sometimes go a bit overboard in touch / marketing but Wren has essentially been perfect. Now, like the friend who originally turned me on to them, I pass along the recommendation to anyone who expresses interest.
A great organisation, doing good, quantifiable work to help the environment. Also very approachable and helpful.
