Say goodbye to greenhushing in 2025 and keep up a steady beat of messaging throughout the year using our calendar of key dates as ‘hooks’.
Communicating about your program with us, alongside the broader climate action you are taking, is a great way to engage your colleagues, customers, and other stakeholders, while encouraging fellow corporates to step up, set goals, and take action.
To help you do just that, we've pulled together a calendar of key dates relating to climate and sustainable development. Using these dates as “hooks” throughout the year can help you keep a steady drumbeat of messages and provide opportunities for your messages to reach an even bigger audience.
We’ve also included some useful industry events you might want to consider attending, as well as important reporting and award entry deadlines.
