Yes! You can sign our International Pledge.
But we need Mobilizers in every country to take the reins in advocating, spreading, and potentially revising your country's Pledge. Only nationals can know what language, cultural references, and practical factors are most appropriate and most appealing to their countrymen and women. Note: The one thing we do not want to change is making the targets weaker. Though if you think your country can hit net zero before 2030, we would be happy to move it forward!
