- more CO2 per heat unit
Examples
-
The entire apple country, he explained, could be quantified and mapped in terms of "heat units" -- a measurement, in essence, of the amount of heat in an orchard during a given day -- a piece of information so vital to growers that it is broadcast throughout the growing season on local radio stations.

The Scoville heat unit measures the spiciness of peppers based on the heat they produce.
-
And that gives you the exact Scoville heat units of that pepper sample.

Because coal is much less expensive per heat unit than oil or natural gas, a carbon tax increases the price of coal relative to oil or natural gas by a ratio much greater than the emission rate of coal relative to oil or natural gas.

The more "heat units" accumulated, the more OHC (all other things being equal, of course), and thus a warming influence on the atmosphere.

Oil emits 40% more carbon per heat unit than natural gas (Manne and Richels, 1990).

Most simply, electricity and thermal heat from e.g., coal or oil have a great difference in their ability to do work, such as we are willing to trade three or four heat units of coal or oil in a thermal plant for one thermal unit of higher quality electricity.

Because the combustion of coal emits more CO2 per heat unit than oil, which emits more CO2 per heat unit than natural gas, the tax on coal would be larger than the tax on oil, which would be larger than the tax on natural gas.

Morphology
The meaning ‘a unit of measurement for heat energy’ is directly and predictably built from 'heat' (thermal energy) + 'unit' (a measure), so a learner who knows both words can derive the MWE meaning. This noun–noun compound follows a common compositional pattern found across languages and in technical registers (e.g., 'energy unit', 'power unit'), making it transparent to a B1 learner.
Etymology
Heat unit comes from the need for a simple, standard 'amount' of heat that people could compare, and the word unit shows it is one fixed amount used for measuring. For example, an early 'heat unit' was the 'calorie', the heat needed to raise a small amount of water by one degree, so today a heat unit means any standard measure of heat energy.
