In 2020, virtual events surged by over 1000 percent. In 2024, they’re not just more frequent — they’re more sophisticated, multi-layered, and surprisingly… heavier on carbon than you might think.
If you’re using virtual events hosting platforms, chances are your AV setup is silently shaping your event’s environmental impact. Yes, those dazzling high-res cameras, flashy backdrops, and 4K streaming speeds come with an invisible cost — your carbon footprint.
But here’s the real deal: You can still wow your audience without weighing down the planet.
The AV Energy Equation: Why Every Choice Counts
Ever wondered how a simple switch from 1080p to 4K video affects your emissions? According to the International Energy Agency (2023), streaming one hour of high-definition video can generate up to 220g of CO₂, while audio-only drops it to just 8g. Multiply that by hundreds or thousands of attendees and… the numbers stack up.
Here’s a quick comparison table to give you clarity:
| AV Format | Avg. Carbon Output (per hour) |
| 4K Video (high bitrate) | 220g CO₂ |
| 720p Video | 110g CO₂ |
| Audio Only | 8g CO₂ |
| Slide Deck + Audio | 12g CO₂ |
Now, think about your virtual events hosting platforms. Do they default to the highest resolution? Are you using multi-camera setups even when not needed? These small tech choices can turn into big environmental impacts.
Lighting, Bandwidth, and the Green Broadcast Switch
You don’t need to dim the brilliance of your event — just adjust how you produce it.
Here are two overlooked AV tweaks that can slash your carbon impact:
- Lighting Optimization:
Go for LED-based solutions. Avoid over-lighting your space — balanced lighting not only saves energy but improves camera clarity and reduces post-edit work. - Bitrate Control:
Use smart bitrate control tools that adjust streaming quality based on viewer bandwidth — this not only enhances UX but cuts data waste. Platforms like Vimeo, Zoom, and Webex allow granular bitrate settings that can make a real difference.
Are your speakers being broadcast in 4K… even when most attendees are on mobile?
Multi-Cam or Multi-Problem?
While dynamic visuals can boost engagement, not every event needs multiple camera angles. Here’s a better approach: match camera complexity to session purpose.
If it’s a keynote, yes — go cinematic. But for breakout sessions or webinars, a single-angle HD feed does the job. Remember, each extra camera not only consumes power — it multiplies your editing and bandwidth costs.
How much energy could you save by switching just one stream to audio-plus-slides?
Are Your Platforms Helping or Hurting Sustainability?
Not all virtual events hosting platforms are equal. Some offer energy-saving features like adaptive streaming and cloud-optimized rendering. Others still push static high-res streams to every user, no matter the need.
Virtual Velocity steps in here — with a full suite of virtual event services, the platform caters to every AV need, helping you maintain high-impact visuals while aligning with green goals. From scalable bandwidth to eco-smart AV settings, you get results that impress without excess.
Do you know if your event tech stack is eco-smart or just flashy?
How You Can Host a Greener Virtual Event
Let’s break it down. You don’t need to sacrifice quality to reduce your carbon footprint. You just need smart AV strategies. Here’s what you can do right now:
- Review your video settings before every stream. Drop to 720p when 1080p is overkill.
- Use audio-only for sessions where visuals add little value.
- Select platforms that offer bitrate and resolution control.
- Minimize multi-camera setups unless it adds genuine value.
- Educate speakers on lighting — natural light can reduce electricity use.
Your next virtual or hybrid event can be stunning and sustainable.
