With all of the news surrounding climate change and the need to reduce emissions, renewable energy is gaining a stronghold and there is a sharp focus on the reporting of energy usage and carbon emissions. As such, it seems that the petroleum industry is heading for a steep decline. The reality is, however, that renewable energy is not cheap nor is it suitable for heavy industry use; two factors which drive a viable economy. As more people take up alternative and renewable types of energy sources, as obtained from the sun or wind, it the price of localised coal and fuel-powered electricity generation will increase, in direct correlation with the decreased use of so-called 'dirty energy'. Yet, Davide Papa contends that there is no other practical form of energy that could match the energy output of crude oil pound per pound. The decline in the trading of crude oil and associated fuels is not upon us in the near or distant future, if ever and the marketplace is ripe for informed intermediaries to source and sell petroleum based products for a long time yet. Davide sets out a basic, uniform standard of practice and explains, in a clear and straightforward language, the rules and laws that must be adhered to when conducting business in the complex export/import arena, thus guiding intermediaries, brokers, agents, buyers and sellers who are attempting to deal in commodities, including petroleum based products, to success. The insight Davide provides has cross-industry relevance and additionally will appeal to a host of professional entities such as intermediaries, lawyers, scientists, engineers, accountants, corporate and home based traders.
