Public opinion is the only effective counterweight to the immense power of the fossil fuel industry. The industry knows this, which is why it spends so much time and money trying to shape it. Your opinion really does matter. It is your superpower. But it doesn’t count for much if you don’t express it. The Climate Action Now app can help you with that. It is your opinion amplifier. It is your megaphone. This app does the work so that you don’t have to. It provides an endless stream of well-researched, well-written, personalized messages that you can send to political and business leaders advocating for climate action in just seconds with just a few touches! And you’ll learn a lot about the issues and earn real trees as you go. FAST. Most actions in the app – like contacting your elected officials, emailing CEOs, or asking media influencers to step up – can be taken with just a few touches in just a few seconds. We’ve done all the work for you so that you don’t need to. Don’t know who your elected officials are? Give the app your location, and it will tell you. Don’t know how to contact them? The app has their email addresses and phone numbers. Don’t know what to tell them? The app gives you personalized, well-written, powerful messages that you can send in seconds. IMPACTFUL. Climate Action Now gives you, whether you are a concerned citizen or a hard-core climate activist, the means to take thousands of individual, collective, and systemic actions NOW. To date, app users have sent over one MILLION messages and planted over 47,000 trees. You can send an impactful message in seconds. Did you know that just 100 companies, and the politicians, investors, and regulators who enable them, are responsible for over 70% of the world’s emissions? Climate Action Now makes it easy for you to influence them with emails, petitions, and phone calls. Did you know that the fossil fuel industry is poisoning communities of color in their own backyards? Climate Action Now helps you fight these injustices and demand an equitable future for all. Did you know that leading climate activists say the most important thing you can do about climate change is to talk about it? Every action you take with Climate Action Now is automatically posted to the app's Community Feed where people can see it, take that action also, comment on it, like it, and share it with others. REWARDING. Every action you take earns points, and when you’ve earned enough points, a real tree will be planted. Every action you take sets an example for others to follow. Join a team and every action you take contributes to the team’s total and helps it win rivalries with other teams. Through all these things, you earn the most important reward of all: knowing that you’re doing your part to save our planet. Time is short, and the future is in our hands. Literally. Together, with a phone or tablet and a few minutes a day, we can all take Climate Action Now.
