This report from the Japanese Institute for Global Environmental Strategies shows how lifestyles would have to change in industrialised countries and some industrialising countries in order to meet climate change targets.
Lifestyle emissions are defined as those directly or indirectly caused by consumption within households. This excludes emissions caused by governments or the building of infrastructure. To meet the Paris climate target of limiting warming to 1.5°C, per capita annual lifestyle emissions will need to fall to 0.7 tonnes of CO2 equivalent, compared to current footprints of 10.4 tonnes CO2 eq. in Finland, 4.2 tonnes CO2 eq. in China and 2.0 tonnes CO2 eq. in India.
The report finds that lifestyle emissions will need to be reduced by 80–93% by 2050 in industrialised countries and 23–84% by 2050 in industrialising countries. It recommends reducing meat and dairy consumption in addition to reducing use of air travel, cars and fossil-fuel based energy.
