How can trade policy respond to the needs of mitigating the climate trends by reducing the anthropogenic greenhouse house emissions and how can we deal with concerns of more than a billion people in the developing world that lack access to energy for fulfilling their daily needs such as cooking and lighting? From this perspective, this paper looks at specific examples of sustainable energy goods-namely, solar technologies and associated products that have become an increasingly popular and cost-effective choice to deliver electricity to people not connected to the grid. The paper examines a number of domestic policy and market bottlenecks that stifle growth and the rate of uptake for solar products and how they can be overcome. It then investigates patterns of trade in products such as solar lanterns and solar panels, policies that hinder trade such as import tariffs and taxation and a range of trade-relevant issues including, among others, those related to customs classification practices and delays in customs clearance and standardization. The paper finally explores how some of these trade-related barriers could be addressed within the context of a sustainable energy trade agreement for a positive impact on expanding access to sustainable energy.
