Tourism appears as a catalyst for growth and development; however, recent studies have documented that this sector heavily depends on energy sector and as a consequence, entire tourism industry has been blamed for CO₂ emissions. This study aims to investigate the impact of tourism develop, renewable energy and real GDP on CO₂ emissions for G20 economies during the period of 1995-2015. In the presence of panel unit root, Pedroni and Kao methods confirm long-run cointegration among variables. FMOLS results show that a 1% increase in tourism development decreases pollution emissions by 0.05% in long run. The results show that the increase in renewable energy consumption reduces pollution emissions. A 1% increases in renewable energy reduces pollution emissions by 0.15% in long run. There was an inverted U-shaped relation between pollution and real GDP in long run confirming the validity of environmental Kuznets curve. Paper concludes that tourism development can be driving force for CO₂ emissions reduction.

旅游业似乎是增长和发展的催化剂；然而，最近的研究表明，该部门严重依赖能源部门，因此，整个旅游业都被归咎于 CO ₂排放。本研究旨在调查旅游业发展、可再生能源和实际 GDP 对 CO _2的影响G20 经济体在 1995-2015 年期间的排放量。在存在面板单位根的情况下，Pedroni 和 Kao 方法证实了变量之间的长期协整。FMOLS 结果表明，从长远来看，旅游发展每增加 1%，污染排放量就会减少 0.05%。结果表明，可再生能源消费的增加减少了污染排放。从长远来看，可再生能源每增加 1%，污染排放量就会减少 0.15%。长期来看，污染与实际GDP呈倒U型关系，证实了环境库兹涅茨曲线的有效性。论文得出结论，旅游业发展可以成为减少CO ₂排放的驱动力。
