It is clearly made up data, as for example they predict the outcome of policies like carbon costs.

Afaik even economists don't agree on the results of such policies.

They are just making an assumption and the whole app is merely advertising for their preferred type of policy.

You’re right, the climate data is likely to be solid but the economic modelling dubious.

I think you are being mistaken for saying the climate data they are using is made up, but your point is more subtle- they don’t show their work to tell you what the biofuel subsidies, for example, will do to CO2 levels.

I don't know about their climate data, I just think their claims of the impact of carbon costs are pure speculation. If they had a calculator for determining temperature increase depending on carbon output, it would be more credible.

They are piping two complex system into each other - economic and climate. At least economics are not understood well enough to really make such predictions. And if the output of the economic model is unreliable, so is the result of the climate model.
