The consumption of products, services and transportation has significant environmental consequences and account for the majority of global greenhouse gas emissions. Meanwhile, demand-side policy measures have the potential to reduce the environmental footprint of these activities by up to 40-70%. This Policy Paper draws on the OECD’s recent household survey on environmental policy and behavioural change to provide insights and policy recommendations for specific measures that can encourage more sustainable household consumption of energy, transport and food as well as more sustainable waste practices. The report was prepared in support of Japan’s 2023 G7 presidency.
