We hope you’re getting excited about CHI 2025 in Yokohama! We organizers are working hard to make the conference as inclusive as possible.

In this blog post, we want to ask for your help with planning, if you might attend the conference and would require accessibility support.

Planning accessibility support for the conference is tricky. It requires in-advance preparation, particularly when it comes to hiring necessary services.

So, we would like to connect with potential conference attendees who may need accessibility support. While we understand that many of you cannot confirm whether you will attend or not until you receive your submission results, we encourage early communication about your potential needs. Even if you’re not completely certain about attending, knowing that you’re considering it helps us plan more effectively.

Please contact us at accessibility@chi2025.acm.org to discuss your accessibility requirements. And to ensure we can accommodate your needs, we ask that all accessibility requests be submitted by February 28th, 2025.

Thanks for taking the time to read this! Your early heads-up helps us a lot! Looking forward to communicating with you!

The CHI’25 sustainability committee is excited to announce the return of the Special Recognition for papers that take exceptional measures toward sustainable research practices. This initiative aims to draw attention to sustainable research and celebrate authors’ dedication to sustainability. This honor is open to any project that has taken steps to be more sustainable–not only projects that directly address sustainable topics. Thus, we will again consider two tracks for this recognition: i) research with potential for sustainable impact and ii) research teams with inspirational research practices.

There are many creative ways that HCI researchers could consider to make their work more sustainable and potentially earn a Special Recognition for Sustainable Practices, including:

• Offsetting carbon costs (e.g., of training machine learning models)
• Hosting a no-waste workshop
• Purchasing recycled materials
• Minimizing project-related travel (e.g., holding hybrid and virtual meetings)
• Incorporating community leaders in project funding
• Advocating for sustainable policy
• Public outreach or education on sustainable topics or practices
• Reducing electronic waste (e.g., through sustainable purchasing practices, reusing and recycling parts)

Any of these actions or similar could earn your project a Special Recognition for Sustainable Practices. We hope to hear many other creative ideas! Read more about last year’s winners here: https://chi2024.acm.org/2024/05/08/special-recognition-for-sustainable-practices-winners-runners-up/ 

How to Apply
The submission portal in PCS will include a new field where authors of accepted papers can describe steps to make their work/projects more sustainable. In 2-3 paragraphs (300 words or less), tell us what actions you’ve taken to make your project more sustainable, your reasoning for taking those actions, and what impact you’ve seen. Note: What you enter there is separate from the review process. Additionally, this is a relatively new effort to promote sustainability; hence, we are still trying things out, and you’re welcome to submit comments or feedback to sustainability@chi2025.acm.org.

Special recognitions will be announced before the first day of the conference on April 26th. Papers receiving special recognition will be highlighted on Twitter/X and mentioned in the closing keynote during the conference. A badge will also appear in the conference program.

CHI 2025 Terms & Conditions
All cancellations received on or before Saturday, April 5th, 2025, are entitled to a refund, minus a 9% processing fee of fees paid. No refunds will be given after Saturday, April 5th, 2025. Regrettably, cancellations received after that date cannot be honored. The conference committee recognizes that sometimes last-minute cancellations can’t be avoided. However, the conference incurs expenses for which it is liable based on registration counts. Cancellations must be submitted in writing to chiregistration@executivevents.com. Registrants who find themselves unable to attend should be aware that registrations are transferable, but in general, the conference committee cannot assist in finding an appropriate replacement. Substitutions for paid registrants may be made up until Friday, April 25th, 2025 with written notice to chiregistration@executivevents.com.
In the event that you need to change from an in-person conference registration to a virtual conference registration, CHI will grant a refund for the difference. Changes in registration must be sent to chiregistration@executivevents.com on or before April 25th, 2025. Changes made after this date will not be eligible for a refund.
In the event that a workshop is canceled due to circumstances beyond the organizers’ control, refunds are not guaranteed. If refunds are issued, the amount will depend on the expenses and financial commitments incurred by the workshop as of the cancellation date.
Student registration rates are for full-time students only.
