Concerns have been raised against using carbon pricing for fighting climate change, as these might disproportionally affect lower-income households and thus increase inequality. However, the distributional implications of policies will depend on policy design their capacity to reduce change impacts. To quantify interaction between benefits economic inequality, we develop a numerical climate-economic framework featuring both within- between-country income heterogeneity. We implement well-below 2°C target examine variety redistributive schemes. find that impacts inequalities within across countries. Climate reduces this by half, an appropriate transfer scheme targeted at low-income can eliminate it altogether. An equal per-capita redistribution leads most population being economically better off already today. The analysis shows importance including in evaluation policies.

Earlier meta-analyses of the economic impact climate change are updated with more data, three new results: (1) The central estimate global warming is always negative. (2) confidence interval about estimates much wider. (3) Elicitation methods most pessimistic, econometric studies optimistic. Two previous results remain: (4) uncertainty skewed towards negative surprises. (5) Poorer countries vulnerable than richer ones.

A large discrepancy exists between the dire impacts that most natural scientists project we could face from climate change and modest estimates of damages calculated by mainstream economists. Economic assessments risks are intended to be comprehensive, covering full range physical their associated market non-market costs, considering greater vulnerability poor people challenges adaptation. Available still fall significantly short this goal, but alternative approaches have been proposed attempt address these gaps. This review seeks provide a common basis for scientists, social modellers understand research involved in evaluating economic change. Focusing on estimation processes embedded integrated assessment models concerns raised literature, summarise frontiers relevant improving quantitative damage estimates, representing complexity systems, impact various assumptions used manage complexity.
