1.5 Degree Lifestyles

Addressing climate change will require radical changes in lifestyles: says this report by international consortium of research institutes 2019


  • 3-2-1 tonnes per person by 2030-2040-2050 Globally, citizens and society need to aim for per-person consumption-based greenhouse gas emissions targets of 2.5 (tCO2e) in 2030, 1.4 by 2040, and 0.7 by 2050 in order to keep global temperature rise to within 1.5 degreesLifestyle Carbon Footprints ‘Carbon footprint’ refers to GHG emissions directly and indirectly caused by activities or products throughout their lifecycle, from a consumption perspective, and can be calculated for products as well as daily activities of individuals or organisations (Wiedmann and Minx 2008). The focus of this study is on daily activities of individuals determined by the choices they make on ways of living. In this study, ‘lifestyle carbon footprint’ is defined as the GHG emissions directly emitted and indirectly induced from household consumption, excluding those induced by government consumption and capital formation.
  • Human carbon sinks affect the targets The various reduction scenarios we studied indicate that the target levels of reductions are sensitive to whether negative emission technologies such as carbon capture and storage (CCS) and bioenergy with carbon capture and storage (BECCS) are used. If use of such technologies is considered over the long term, the upper limits of the proposed targets are slightly eased (i.e., slightly easier to achieve), for 2030, 2040 and 2050 (in parentheses): 2.5 (3.2), 1.4 (2.2), and 0.7 (1.5) tCO2e, respectively. However, the actual availability, feasibility and costs of these technologies are uncertain, thus solely relying on its assumed extensive and broad-ranging roll-out is a risky societal decision.
  • 72% of global Greenhouse Gas emissions are related to household consumption. whilst the rest stem from Government and investments
