I assume the following items don't have EMC values simply because the values haven't been added yet.
(I have only listed items that can be obtained in survival, following the pattern from Project E)

Missing

- Stripped Bamboo
- Mangrove + Propagule + Logs + Leaves + Roots
- Cherry + Sapling + Logs + Leaves
- Blackstone
- Warped Wart Block
- Shroomlite
- Soul Soil
- Brown&Red Mushroom Blocks

- Totem of Undying
- Poisonous Potato
- Echo Shard
- Dragons Breath
- Globe&Snout Banner Pattern - Pottery Sherd(s) - Bottle o' Enchanting

I have provided the list as a comprehensive reference.

Also, I feel like Items which would technically calculate to being an EMC value of less than 1 but greater than 0 based on their recipe,
should just have an EMC value of 1 for convenience.
(this also seems to be the pattern from Project E)

There are also inconsistencies between Waxed/Weathered/Cut combinations of Copper
