Abstract: Evaluation of noise pollution level has been carried out in in some selected Sawmill factories in Port Harcourt and environs using noise level and frequency meters in seven locations. The mean values of maximum and minimum sound levels in Mile2, Mile3, Marine base, Oluwood were 81.98±0.43 and 79.28±2.00, 82.450±0.66 and 80.28±0.80, 81.50±4.73 and 74.75±1.10, 81.40±0.40 and 78.03±2.02 respectively. Also the mean values of maximum and minimum sound levels at Igwuruta, Rumosi, Rumuji were found to be 82.00±0.64 and 79.40±2.00, 81.53±0.60 and 78.66±1.63, 81.78±0.40 and 77.95±1.86 respectively. The average noise equivalent (Leq) ranged from 77.20 to 82.25 dB whereas the average noise pollution level (Lnp) ranged from 96.13 to 101.23 dB. Therefore, the indication is that the Sawmill at Igwuruta has the highest average Lnp whereas Rumuosi has the least average when compared with the recommend permissible value by the Nigerian Federal Ministry of Environment (FMEnv). This study has determined the noise level generated in study area through set objectives which included but not limited to measuring the sound level, investigating noise some meters away from the source and of course comparing results with best known standards. The results therefore suggested that the noise level is high at the saw mills and the day exposure to this unwanted sound could threaten the health of the factory workers and the residents at proximity to the noise sources.

Abstract: Hydrocarbon business globally, commands enormous influence over the dynamics of financial integrity on wealth creation in the world economy, through global trade. Citing example with Nigeria’s Oil and Gas industry, her richly endowed mineral deposits, for the past six decades has (directly or indirectly) played very significant role on virtually all economic and commercial activities; in determining the financial health/viability of the nation’s economy. The global economy presently faces challenges of the global warming due to the climate change that has occurred as a result of incremental growth in energy demands and consumption. Energy, known as a critical factor to life is essential for purposes of powering the economy through daily economic activities, and also for maintenance of man’s existence, has its own consequences on the environment in the course of its production and utilization. As a result, it has been proven to be posing a number of challenges, threats to life and man’s sustainable existence because of the adverse incidences on the planet, resulting from impact of carbon emissions being generated from energy consumption of fossil fuels/Oil and Gas sources (among other greenhouse gases, GHGs). Energy transition, as a phenomenal trend on the global energy solutions management, would contain these global challenges (in ever increasing global population with its imminent threat of energy crisis/poverty) by applying energy-mix menu and technologically advanced initiatives (the proposed Maximum energy-minimum emissions strategy) to control global warming by net-zero carbon emissions target through decarbonizing technologies; for sustainability of the planet.
