In this study, the impact of energy, agriculture, macroeconomic and human-induced indicators on environmental pollution from 1971 to 2011 is investigated using the statistically inspired modification of partial least squares (SIMPLS) regression model. There was evidence of a linear relationship between energy, agriculture, macroeconomic and humaninduced indicators and carbon dioxide emissions. Evidence from the SIMPLS regression shows that a 1% increase in crop production index will reduce carbon dioxide emissions by 0.71%. Economic growth increased by 1% will reduce carbon dioxide emissions by 0.46%, which means that an increase in Ghana's economic growth may lead to a reduction in environmental pollution. The increase in electricity production from hydroelectric sources by 1% will reduce carbon dioxide emissions by 0.30%; thus, increasing renewable energy sources in Ghana's energy portfolio will help mitigate carbon dioxide emissions. Increasing enteric emissions by 1% will increase carbon dioxide emissions by 4.22%, and a 1% increase in the nitrogen content of manure management will increase carbon dioxide emissions by 6.69%. The SIMPLS regression forecasting exhibited a 5% MAPE from the prediction of carbon dioxide emissions.

The causal nexus between energy use, carbon dioxide emissions, and macroeconomic variables in Ghana Asumadu-Sarkodie, Samuel; Owusu, Phebe Asantewaa (2017-01-01) The study examined the causal nexus between energy use, carbon dioxide emissions, and macroeconomic variables in Ghana with data spanning from 1960 to 2013 using the vector error correction model (VECM). It is evidential from the study that almost 12% of future fluctuations in energy use are due to shocks in financial development and 10% of future fluctuations in carbon dioxide emissions are due to shocks in energy use. There was evidence of a bidirectional causality between: energy use and financial develo...
The relationship between carbon dioxide, crop and food production index in Ghana: By estimating the long-run elasticities and variance decomposition Sarkodie, Samuel Asumadu; Owusu, Phebe Asantewaa (2017-06-01) The study estimated the relationship between carbon dioxide, crop and livestock production index in Ghana: Estimating the long-run elasticities and variance decomposition by employing a time series data spanning from 1960-2013 using both fit regression and ARDL models. There was evidence of a long-run equilibrium relationship between carbon dioxide emissions, crop production index and livestock production index. Evidence from the study shows that a 1% increase in crop production index will increase carbon d...
The relationship between carbon dioxide and agriculture in Ghana: a comparison of VECM and ARDL model Asumadu-Sarkodie, Samuel; Owusu, Phebe Asantewaa (2016-06-01) In this paper, the relationship between carbon dioxide and agriculture in Ghana was investigated by comparing a Vector Error Correction Model (VECM) and Autoregressive Distributed Lag (ARDL) Model. Ten study variables spanning from 1961 to 2012 were employed from the Food Agricultural Organization. Results from the study show that carbon dioxide emissions affect the percentage annual change of agricultural area, coarse grain production, cocoa bean production, fruit production, vegetable production, and the ...
Recent evidence of the relationship between carbon dioxide emissions, energy use, GDP, and population in Ghana: A linear regression approach Asumadu-Sarkodie, Samuel; Owusu, Phebe Asantewaa (2017-01-01) In this study, the relationship between carbon dioxide emissions, energy use, GDP, and population was examined in Ghana from 1971-2013 using a linear regression approach. Evidence from the study shows a long-run equilibrium relationship running from energy use (EU), gross domestic product (GDP), and population to carbon dioxide emissions. There was evidence of long-run equilibrium relationship from GDP to carbon dioxide emissions and population to carbon dioxide emissions. There was a unidirectional causali...
The causal effect of carbon dioxide emissions, electricity consumption, economic growth, and industrialization in Sierra Leone Asumadu-Sarkodie, Samuel; Owusu, Phebe Asantewaa (Informa UK Limited, 2017-01-01) The study investigated the causal effect of carbon dioxide emissions, electricity consumption, economic growth, and industrialization in Sierra Leone from 1980-2011 by employing the linear regression and the vector error correction models. Evidence from both models show a long-run equilibrium relationship between carbon dioxide emissions, electricity consumption, economic growth, and industrialization in Sierra Leone. Evidence from the variance decomposition shows that 7% of future shock in carbon dioxide e...
