1. Introduction
Globalization has propelled many countries to economic progress, which has had a significant impact on the socioeconomic, environmental, and political aspects of human existence. Globalization increases the interdependence of countries via the production and investment of goods and services, capital transfers, financial convergence, technological change, and knowledge sharing. Because of the extent of trade liberalization, financial development, technical advancement, and economic progress, there have been significant concerns about global environmental quality. Although each country aspires for strong GDP (Gross Domestic Product) development, trade, technology transfer, foreign investment, urbanisation, and industrialization all contribute to air, water, and land pollution. As a result of the increasing usage of traditional energy sources in key economic activities, the environmental situation has deteriorated [

2 emissions and other greenhouse gases in order to raise awareness about the harmful effects of burning fossil fuels on humans and wildlife, as well as the implementation of a carbon tax, inventions, energy conservation, and high-efficiency technology [

6].
Although the world takes risks in terms of global advancement, it works hard to preserve the environment. Many studies discovered that countries needed to develop specific strategies to minimize these degradations in order to improve environmental sustainability due to the continuous decline in environmental quality. Human demands are limitless, but natural resources are limited, and economic well-being and growth phases are prominent in economic studies; in this scenario, energy consumption is to blame for waste and environmental deterioration [

9]. Economic globalization may have a favourable or detrimental impact on emission levels in the environmental debate. On the one side, more trade and globalization will result in lower import tariffs and increased economic investment. Economic growth and development levels will both increase. Then, since fuel is utilized as an input in the manufacturing process, the emissions would rise. The immediate effect is the result of this globalization of trade. More free trade, on the other hand, helps to enhance the structure. From an energy-dependent pre-industrial environment and established economy, the economy may transition to a green industry and service economy. Emission levels will be reduced due to changes in the economic structure as a result of trade globalisation [

Global warming is now the most serious environmental problem confronting humanity. Without appropriate supervision, such a tendency would have disastrous consequences for the environment, the economy, and human life. Climate change has an impact on human behaviour and practises, with carbon dioxide combustion being a major contributor to global warming. Increasing worldwide awareness of environmental problems has aided inter-governmental initiatives such as the Kyoto Protocol and the Paris Agreement. The main aim is to decrease global pollution while also ensuring a balanced economic expansion [
13,
14]. The main intention of the current analysis was to determine the impacts of globalization, energy consumption, trade, economic growth, and fuel importation on the ecological footprint in Pakistan. As many previous studies examined those factors separately, we have investigated their impact together in order to highlight the most significant determinants of the ecological footprint in a developing country that faces great challenges in the environmental protection area. Moreover, many studies have highlighted the impact of these variables on CO
2 emissions, while we have investigated their impact on the ecological footprint, which is a broader concept. We have utilized the annual data variables from 1974–2017, and stationarity among variables was rectified by using the two-unit roots technique. Further, a linear ARDL technique with limited information maximum likelihood and linear Gaussian model estimation were employed to estimate the linkage among variables. The findings supported the policy recommendations which are provided in the final section of this paper.
2. Literature Review
The global social and economic situation has been negatively impacted by environmental problems such as desertification, erosion, global warming, and climate change. The changes in the equilibrium of habitats, air quality, and extreme climatic conditions will result from global warming. Different analyses of the underlying causes and impacts of global warming and climate change have completed observational research over the past three decades. According to works on energy economics, the two most significant factors influencing the climate are energy use and economic growth. High use of fossil fuels has led to a significant increase in environmental degradation throughout the course of industrialisation. The increase in CO
2 emissions is seen as the cost of utilizing fossil fuels and economic growth, and it is a critical problem for the global environmental discussion to solve [
15,
16,
17]. Financial development, for example, increases consumer trust in purchasing houses, equipment, air conditioners, and cars, all of which increase energy consumption and, as a result, contribute to environmental problems. Similarly, financial expansion eliminates spending barriers for companies by providing financial resources. Investors will ultimately design and build new industries that use a lot of energy and emit a lot of trash and carbon dioxide into the environment [
18,
19,
20].
Globalization is also changing many aspects of the planet today, including culture, travel, language, way of life, and foreign relations; however, trade and environmental policy guidelines have a major impact on the potential to affect environmental sustainability. Currently, the world is transitioning from a traditional economic and financial framework to a more linked, innovative, and competitive market. There is little dispute that globalization rewards those that change market patterns, create economies of scale, and improve their inventiveness. The global contemporary environment has resulted in many economic changes, increasing reliance on home wealth and resulting in growth. However, in the context of economic and financial globalization, the fast-moving trends of international corporate solidarity, cost minimization, and commercial independence have stimulated people’s interest in learning about the environmental impacts [
21,
22,
23]. Globalization is a multi-faceted process that is becoming more and more the guiding factor behind the dynamic world economies. Since the start of the 21st century, globalization, in different fields such as finance, politics, and culture, has produced a new millennium of transactions. Now the old concept that the globe is growing smaller applies not only to the simplicity of travel and connectivity, but also to the purchase and sale of products and services on international and foreign markets. The term “globalization” currently refers to the merger of many markets that leads to worldwide growth via investment, such as international exchange [
24,
25,
26].
According to Shahbaz et al. [
25,
27], globalization is a significant driver of the total energy demand. Fossil fuel sources create usability problems for the next generation. Price instability in fossil fuels imports is a disadvantage of their use and leads to bad economic effects [
28]. Several studies have examined the effects of trade on the environmental indicators such as CO
2 emissions. Many studies have been conducted to observe the effect of trade on various environmental variables such as CO
2 emissions and total energy consumption for developed and/or developing countries [
29,
30,
31,
32,
33,
34], with varied results. Some found a positive correlation between trade, energy consumption, and CO
2 emissions, while others discovered an inversed U-curve, as well as uni-directional or bi-directional causality between these indicators. With the development of renewable energy sources, studies started to focus on investigating the relationship between trade and renewable energy [
35,
36,
37] and found a positive relationship between trade and renewable energy use in OECD countries, in Europe or in Asian countries, which improves environmental conditions. However, Uzar [
38] found that trade does not impact renewable energy consumption.
The environmentally friendly footprint examines the impact of human activities on the environment. Human demand pressures on arable soil, pastures, wetlands, cumulative soil, carbon footprint, and the ocean are all monitored. Human demand has outstripped resource efficiency, and we are confronted with an enormous dilemma. Strengthening demand and supply would decrease the planet’s generational potential, produce greenhouse gases and pollution, consume energy, and possibly destroy our ecosystems. Recent environmental studies are increasingly using ecological footprint to evaluate the influence of human demand owing to its wide characteristics and ability to absorb the indirect and direct effects of development and energy use [
39,
40,
41]. The economic and social growth of a nation is a key measure of natural resource rental, but intensifying industrial development and urban development, depletion of natural resources, low exploitation and lack of technology can all decrease a country’s natural resources, as does renting natural resources. Globalization increases the productivity of natural resource exploitation via creative technology [
21]. Carbon dioxide emissions are seen as a measure of environmental pollution in most environmental assessments, but they represent just a limited proportion of environmental degradation. The ecological footprint is a globally comparable, comprehensive, and reliable assessment of environmental impacts. Human activity’s impacts on land, air, and water in ecosystems have lately been shown to be more prevalent than carbon dioxide emissions [
42,
43,
44].
Economic growth has contributed to a massive use of fossil fuel energy in the industrialization phase. Currently, the global economy is highly dependent on energy input in all facets of the economy. It poses energy protection and sustainability problems and produces high levels of greenhouse gas pollution at the same time [
31]. Economic development is one factor influencing energy use and carbon emissions are the other. We must acknowledge economic growth in order to support environmental improvements while meeting rising energy demands. The use of green energy will compensate for the irregularity of the energy mix sector and help to protect the environment. When compared with other energies, renewable energy has a lower impact on the environment, making the transition to a low-carbon economy a critical component for renewable energy. Moreover, renewable resources and international tourism flows will have a beneficial impact on foreign investment, research and development expenditure, trade, employment, quality of life, and a country’s growth and development [

The EKC has carried out investigations focused on various environmental metrics including emissions of carbon dioxide, carbon footprint, sulphur emissions and environmental footprint, such as different resource use, trade openness and information technology parameters. However, the details of the analysis remain unfinished. Secondly, the most used environmental proxy was still carbon dioxide pollution. There are, however, costs for taking the wrong approach in managing carbon dioxide emissions. For example, water transferred to solid waste causes emissions of carbon dioxide from nitrogen oxides and sulphur to increase later on. Similarly, concentrations of carbon dioxide are a detrimental measure of environmental damage, and the depletion of the atmosphere goes outside the limits of the carbon dioxide pollution. More inclusive measures of environmental deterioration should instead be used [
49,
50,
51]. Economic activities and progress have increased throughout human history. With such advancements, human demand for natural resources such as food, resources, raw materials, and a safe environment has risen considerably. Human hunger for biodiversity has resulted in environmental stress due to the use and depletion of natural resources, the discharge of waste and pollutants, and the extinction of animals, thus altering the global ecosystem. Global warming does not just exacerbate the impacts of stress on the environment; it also leads to habitat degradation, increased waste, biodiversity loss, and increased susceptibility of developing economies to adverse impacts. People’s environment has deteriorated, putting the futures of all living beings in danger. As a result, the global economy is looking for better ways to avoid social and environmental issues [

5. Concluding Remarks and Policy Implications
High-level policies (European Green Deal and the United Nations Sustainable Development Goals) aim to decouple the economic growth from extensive resource use and environmental degradation and suggest the efficient use of resources as a solution. Scientific debates on these issues were initially launched in the 19th century and there is still no consensus. Recent studies find no clear proof of a significant decoupling between growth and environmental degradation at a global scale [
76,
77,
78].
While some EU countries achieved a decrease in some types of environmental degradation between 1995–2015, the decoupling between growth and environmental footprints is very relative and varies among economies [
79]. Such developments are determined by many factors such as structural economic change of non-EU countries and the financialization of EU ones [
80]. A total and significant decrease in the environmental pressures and impacts would require some dramatic transformations of economic systems and of society as a whole, rather than some relative efficiency achievements.
In time, the entire world has realized the need to adapt the new policies regarding climatic changes, and started to accepted an environmentally friendly behaviour [
81]. Sustainability, green innovation, and investment in no-waste and green initiatives have been proven to promote sustainable economic growth and wealth [
82] and represent the most efficient way to elevate a country [
83]. The relationship between pollution, globalization, and economic growth has been investigated by many researchers because of global warming that causes increasingly negative socioeconomic effects [
84].
The main aim of the current analysis was to expand existing knowledge by bringing together and investigating, in the same model, the impact of globalization, energy consumption, trade, economic growth, and fuel importation on the ecological footprint in Pakistan. The study used annual data from 1974–2017 and its stationarity was rectified by using two-unit root tests. A linear ARDL technique with limited information maximum likelihood and linear Gaussian model estimation were exploited to check the relationships between the variables. Th outcome shows that in the long-run, globalization, energy usage, trade, and GDP growth have a productive interaction with the ecological footprint, while fuel importation reveals the adversative linkage to the ecological footprint in Pakistan. Likewise, the findings of the short-run scenario also display that globalization, energy usage, trade, and GDP growth have a constructive linkage, but fuel importation uncovers an opposing linkage to ecological footprint. The results of limited information maximum likelihood also revealed that the variables globalization, energy usage, trade, and fuel importation have a productive linkage, while GDP growth uncovers an adversative linkage to ecological footprint. Moreover, the results of linear Gaussian model estimation also revealed that globalization and energy usage have a constructive linkage, while other variables including trade, GDP growth, and fuel importation demonstrated an adversative linkage to the ecological footprint in Pakistan.
Based on this study’s analytical findings, it is proposed that policymakers and officials continue to enhance their interventions aimed at promoting successful trade strategies, economic development, fuel use, and, in particular, reducing carbon emissions. This would limit the extent of harm to ecosystems, maximise economic productivity, and maintain sustainable environments. In Pakistan, globalization, politics, environment, and legislation have had a severe effect. Pakistan has faced both the beneficial and detrimental impacts of globalization, as have many other developed countries. The community and lifestyle of each municipality is its own. Pakistan has a diverse and interesting culture and has maintained historical practises. Economic globalization also offers emerging countries the possibility to increase their export markets and draw foreign investments and thereby achieve growth. Another positive impact of globalization, which is beneficial for customers who obtain goods at progressively lower costs, is represented by the higher competition between firms. Free exchange between industrialized and developing countries is more advantageous, since they can purchase products at lower rates and therefore provide a better living standard. Trade openness should also be seen as a various action of poverty reduction.
