What type of world do you want to live in by 2030? That’s the question driving this year’s Social Good Summit, kicking off Sunday morning in New York. Over two days, United Nations leaders, entrepreneurs, and advocates will come together in a conversation about the challenges facing our world – and how technology and innovation can spark lasting change.

One year ago in a historic UN summit, world leaders adopted the Sustainable Development Goals, 17 interconnected goals designed to end poverty, fight inequalities, and tackle climate change.

Now is the time to reflect on the progress we’ve made and share ideas on how to create a healthy, peaceful, and prosperous planet for everyone. One thing is clear: We need engaged citizens and innovators, because global problems can’t be solved by governments alone.

On September 18-19, as world leaders gather in New York City for the UN General Assembly, the Social Good Summit will bring global citizens together to have that conversation. And the participants in New York will be joined by participants in dozens of countries around the world who will be having similar discussions on how technology and innovation can drive change in their communities.

The Social Good Summit will also kick off an exciting moment: #GlobalGoals Week – a week of action, awareness, and accountability around the Sustainable Development Goals.

Speakers at the Social Good Summit will include UN agency leaders, social good and environmental champions, exciting innovators, U.S. Vice President Joe Biden, and celebrity activists such as Demi Lovato, Cody Simpson, Connie Britton, and others. We’ll cover topics ranging from women and global leadership, sustainable food, and access to education to civic engagement and social media.

The hosts of the Social Good Summit –the UN Foundation, the UN Development Programme, Mashable, and the 92Y – are excited for Sunday and Monday, but there is one more thing we need: You.

We need your voice and your ideas on how we can create the world we want – because to create a better tomorrow, we all need to take action today. Only if people know about these issues can we make real progress. That’s where you come in.

You are invited to join the conversation by using the hashtag #2030Now. Check here on Sunday at 11:30AM ET to tune in to the event.
