The worldwide economic growth of the last century has given rise to a vast consumption of goods while globalization has led to large streams of goods all over the world. The production, transportation, storage and consumption of all these goods, however, have created large environmental problems. Today, global warming, created by large scale emissions of greenhouse gasses, is a top environmental concern. Governments, action groups and companies are asking for measures to counter this threat. Operations Research has a long tradition in improving operations and especially in reducing costs. In this paper, we present a review that highlights the contribution of Operations Research to green logistics, which involves the integration of environmental aspects in logistics. We give a sketch of the present and possible developments, focussing on design, planning and control in a supply chain for transportation, inventory of products and facility decisions. While doing this, we also indicate several areas where environmental aspects could be included in OR models for logistics.

1. Introduction
Operations Research (OR) has been described as the science of better (the slogan of the INFORMS society) as it mainly focuses on minimizing the costs of existing processes. Yet in today’s society, it is not only profits that are important as many people, companies and governments are concerned about the sustainability of our society. So can Operations Research also contribute to a better environment? In our opinion, the role of OR for the environment should get more attention. Operations Research leads to a more efficient use of resources, which is not only cost attractive, but also tends to create less emissions of greenhouse gases. Secondly, Operations Research helps to identify the trade-offs between environmental aspects and costs. Very often, much reduction in emissions can be achieved with only a marginal increase in costs.
Operations Research techniques and especially multi-criteria decision analysis is therefore an important method in this respect.
In this review, we will highlight its (possible) contributions to green logistics, which is the study of practices that aim to reduce the environmental externalities, mainly related to greenhouse gas emissions, noise and accidents, of logistics operations and therefore develop a sustainable balance between economic, environmental and social objectives (http://www.greenlogistics.org/, last accessed on August, 16, 2011). We deal with all aspects of logistics such as
