Which measures make sense to change human behavior in favor of climate protection?

  • Environmental policy measures are often aimed at the ratio of environmentally harmful (“brown”) to environmentally friendly (“green”) production within an industry.

  • To achieve such goals, the green sector can be subsidized or the dirty sector taxed.

  • We show that the two policy approaches have different welfare effects in a monopolistic competitive environment, depending on the design of the instrument (ad valorem or standard instrument) and the initial situation (size of the polluting sector).

  • With a strong green policy (a strong reduction in the polluting sector), a tax is the dominant instrument.

  • If the polluting sector is initially large, a subsidy may be a better instrument with moderate policy objectives.

climate protection measures

Basic measures that are required in any case to achieve the 1.5°C target, but whose implementation alone does not guarantee that the target will be achieved. Only the concrete design and the extent and type of additional measures determine the possibility of achieving the goal. The clearer and earlier the measures are taken, the more reliable the achievement of goals is realistic.
