Abstract
Discussion and analysis on international climate policy often focuses on the rather abstract level of total national and regional greenhouse gas (GHG) emissions. At some point, however, emission reductions need to be translated to consumption level. In this article, we evaluate the implications of the strictest IPCC representative concentration pathway for key consumption categories (food, travel, shelter, goods, services). We use IPAT style identities to account for possible growth in global consumption levels and indicate the required change in GHG emission intensity for each category (i.e. GHG emission per calorie, person kilometer, square meter, kilogram, US dollar). The proposed concept provides guidance for product developers, consumers and policymakers. To reach the 2 °C climate target (2.1 tCO2-eq. per capita in 2050), the GHG emission intensity of consumption has to be reduced by a factor of 5 in 2050. The climate targets on consumption level allow discussion of the feasibility of this climate target at product and consumption level. In most consumption categories products in line with this climate target are available. For animal food and air travel, reaching the GHG intensity targets with product modifications alone will be challenging and therefore structural changes in consumption patterns might be needed. The concept opens up possibilities for further research on potential solutions on the consumption and product level to global climate mitigation.

to be a discussion and analysis of the international climate policy focuses rather on the abstract level of national and regional greenhouse gas emissions obviously emission reductions need to be translated to consumption level in this article
we have always implications of the strictest IPCC emission off ways for heat consumption categories such as fooled shelter growth and
services we consider the increasing global consumption and indicates the required greenhouse gas intensity for different categories being greenhouse gas
emissions the calories their 1st until need to the square meters
per kilogram and the US alone so the proposed concept
provides guidance for policymakers product developers and consumers to
read the 2 week targets the greenhouse gas intensity of consumption need to be reused by a factor of 5 in 2015 climate targets on consumption level a lot of discussion or physically Healthline targets on the product and consumption level in
most consumption categories products in line with his fan stories are available
for animal fools and air travel reaching the greenhouse gas intensity with product modifications alone will be challenging therefore structural changes in consumption patterns might be needed this concept opens up possibilities for further research on potential solutions on the consumption and product level for climate mediation
