Today, sustainability has become an almost mandatory event accessory. However, there are a dozen half-solutions and pretence: brands proudly hand out "environmentally friendly" PLA cups, but they don't know - or don't want to know - that bioplastic can only decompose by industrial composting. Or offering paper straws to show that they're green, although it'd be much greener if they'd ditch straws in all - but less loud.
We know what makes a green event genuinely green.
