Despite its importance, regular measurement of the value of natural resources at national level is still in its infancy and often disconnected from valuation approaches for other assets.
This report explores this question on the basis of detailed mobility data including origin, destination and timing of all trips for a mid-sized European city. ITF developed a model to test various alternative transport system configurations that would provide the same level of mobility (locations and timing) as today.
This report summarises the current situation in fisheries and aquaculture, observing that in many parts of the world these sectors are at risk and do not reach their full potential.
Climate change and, more generally, environmental damage have quantifiable economic and health costs, which weigh on long-term growth and well-being. If left unchecked, climate change is projected to decrease global GDP by 0.7 to 2.5 % by 2060. At the same time, the costs to society of air pollution already appear substantial–equivalent to some 4% of GDP across OECD countries and even higher in some rapidly developing economies.
Consumers only occasionally choose to buy sustainable products. At the same time these consumers say in surveys that sustainability is important to them, and that the government should promote sustainable consumption. This study takes a closer look at public support for sustainable consumption and the associated dilemmas, with the help of a behavioural economics experiment of group decisions.
From oceans and vast rivers to the spring in the garden, we must safeguard our water as a source of well-being, prosperity and progress.
The fates of humanity and of the environment are two sides of the same coin. That is why we must focus increasingly on not just development but sustainable development. To do that, we need to form global coalitions to work for progress on a range of challenges.
Knowledge sharing is critical in fostering urban green growth. Cities in dynamic Asia urgently need to adopt and strengthen green growth models that take into account rapid urbanisation, industrialisation, and motorisation.
"Green growth" and transport combines several different concepts that are central to sustainable mobility, including sustainable economic activity, reduced environmental impact and sustained growth in high quality jobs.
Natural resources provide essential raw materials and other commodities, and are an important source of income and jobs. They also support the provision of ecosystem services necessary to develop human and social capital.
