Increasing concerns regarding the world's natural resources and sustainability continue to be a major issue for global development. As a result several political initiatives and strategies for green or resource-efficient growth both on national and international levels have been proposed. A core element of these initiatives is the promotion of an increase of resource or material productivity. This dissertation examines material productivity developments in the OECD and BRICS countries between 1980 and 2008. By applying the concept of convergence stemming from economic growth theory to material productivity the analysis provides insights into both aspects: material productivity developments in general as well as potentials for accelerated improvements in material productivity which consequently may allow a reduction of material use globally. The results of the convergence analysis underline the importance of policy-making with regard to technology and innovation policy enabling the production of resource-efficient products and services as well as technology transfer and diffusion.

Projections of UK greenhouse gas emissions estimate a shortfall in existing and planned climate policies meeting UK climate targets: the UK's mitigation gap. Material and product demand is driving industrial greenhouse gas emissions at a rate greater than carbon intensity improvements in the economy. Evidence shows that products can be produced with fewer carbon intensive inputs and demand for new products can be reduced. The economy-wide contribution of material productivity and lifestyle changes to bridging the UK's mitigation gap is understudied. We integrate an input-output framework with econometric analysis and case study evidence to analyse the potential of material productivity to help the UK bridge its anticipated emissions deficits, and the additional effort required to achieve transformative change aligned with 2 and 1.5°C temperature targets. We estimate that the emissions savings from material productivity measures are comparable to those from the Government's planned climate policy package. These additional measures could reduce the UK's anticipated emissions deficit up to 73%. The results demonstrate that material productivity deserves greater consideration in climate policy.

The use of standard time values is advocated as a means of measuring and improving productivity in materials handling. Although handling operations are difficult to schedule and are subject to many variations in order, size and quantity, common and repetitive activities exist which are measurable and controllable. Application of Master Standard Data methods and Method Time Measurement to materials handling operations in a public warehouse have demonstrated that accurate standards can be developed. These standards embrace both physical and cost measures. Although a heavy resource commitment is required to implement these standards and worker attitudes may be negative, adoption of these standards is advocated as a positive action pattern for dealing with typically unprofitable handling operations.

The study of long-term historical trends in material flows has gained some prominence in Ecological Economics since the first studies for Austria and the United Kingdom were published as part of a special section in 2002. This research expands the existing knowledgebase by presenting material flows for the Russian Federation and its predecessor states employing a standard accounting framework. The study of material flows for the Russian Federation provides an interesting and unique case of a planned economy and its transition to a market based form of economic organization. We show that in spite of considerable differences in the physical economy, the USSR developed material use patterns similar to that of Western industrialized economies. Lower levels of consumption were more than outweighed by inefficient production. The transition towards a market economy drove rapid improvements in resource productivity but also growth in metabolic rates. The results indicate that the transition to an industrial metabolic profile proceeds largely irrespective of economic and political conditions. An improved understanding of the evolution of socio-economic systems and the material flows that fuel them is increasingly relevant for designing new systems of production and consumption and facilitating a transition towards a more sustainable industrial metabolism.
