I encourage clients to choose a digital-only delivery of your photos via a private gallery, to minimise the carbon footprint needed for physical deliveries. This doesn't impact on the size or quality of your photos in any way.
If you order a luxury wedding album, I exclusively design and print with a responsible company that shares a similar ethos: you can read Folio's approach here.
I only use high quality rechargeable batteries to power my photography equipment. My home studio is fitted with energy-efficient light bulbs.
I trade-in or donate all my old/unused equipment and gear.
Wherever possible, I travel to weddings and client meetings via public transport.
I will do my best to support other like-minded suppliers in the industry. Directories like Green Union and Natural Wedding Co are good places to start if you're planning an eco-friendly wedding in the UK.
