So you tax them for CO2 and then subsidize them for the same reason?

How does help anyone else than salaries for tax and subsidy administrators?

Not exactly. I'll just copy a reply I made further down: in 2030, a tax will be introduced of 120 DKK (~16€) / ton CO2e, which linearly increases each year until it reaches 300 DKK (~40€) / ton CO2e in 2035. However, the farmers can get subsidies for changing their practices and adopting new technologies, in order to reduce their emissions. I.e., the government will give you money to change your production, so you can minimize the carbon taxes you have to pay. There are more technicalities to how it works, but that's the gist of it. The important part is that the goal is to transition to new technologies and production methods, which reduces emissions per unit food produced.

Without having read the legislation, the two aren't necessarily contradictory. They only are if the subsidy mechanically increases with the tax.

A "climate income" is a good example of that. Everyone gets taxed by usage/pollution, but the collected tax gets redistributed evenly.

That way, on average there is no extra taxation, in fact it's typically a redistribution from top to bottom. And yet every individual will end up with more money the less they pollute. It's that individual incentive that makes the measure effective, but it's the redistribution that makes it socially acceptable (if implemented correctly)

It gets legislation that people in general want (better rivers and streams, healthier sea ecosystem) passed, by subsidizing the changes required for the people those changes negatively affect.

Is it ideal? maybe not, but it is the real world.

Ideally, you gradually ramp down the subsidies, to give folks a gentle offramp.
