Certain upload fields in the Sustainability Portal accept files up to 1GB. Large uploads can sometimes cause connection timeouts, so please follow the tips below to support a successful upload.
Switch to a faster internet connection: An internet connection with higher upload speeds will significantly help.
Use a wired connection: Switch from Wi-Fi to an Ethernet cable for a more stable transfer.
Check your VPN or firewall: Strict networks often interrupt large data transfers. Try temporarily disconnecting your VPN if your organisation permits it.
Upload during off-peak hours: Upload your files early in the morning or later in the day to avoid heavy network traffic.
Use a fresh browser session: Clear your cache or open an incognito window to prevent the portal from timing out due to old background data.
