Pakistan's urban air pollution problems include the advancements to road design and improvement of transport sustainability, increased use of abatement policy by the Pakistani government, and a conversion to clean fuel energy alternatives like CNG. Climate change Natural disasters Due to Pakistan's diverse land and climatic conditions, it is prone to different forms of natural disasters, including earthquakes, floods, tsunamis, droughts, cyclones and hurricanes. A disaster management report claims that the provinces of Gilgit-Baltistan (GB), Balochistan and AJK are vulnerable seismic regions and hence highly susceptible to earthquakes, while Sindh and Punjab constantly suffer from floods because they are low-lying areas. Some of the worst natural disasters that Pakistan has faced include the 1935 Quetta earthquake when around 60,000 people were killed, the 1950 floods when an estimated 2900 people died and 900,000 people were left homeless, the 1974 Hunza earthquake where around 5300 people were killed, the 2005 Kashmir earthquake that killed at least 73,000 and affected more than 1.5 million people, and the 2010 floods, where 20 million people were affected. Forests Pakistan had a 2018 Forest Landscape Integrity Index mean score of 7.42/10, ranking it 41st globally out of 172 countries. Conservation efforts The government has expressed concern about environmental threats to economic growth and social development and since the early 1990s has addressed environmental concerns with new legislation and institutions such as the Pakistan Environment Protection Council. However, foreign lenders provide most environmental protection funds, and only 0.04 percent of the government's development budget goes to environmental protection. Thus, the government's ability to enforce environmental regulations is limited, and private industries often lack the funds to meet environmental standards established by international trade organizations. Government of Pakistan start new campaign with Clean and Green Pakistan to overcome environmental issues. Clean Green Champion Program An initiative named Clean Green Pakistan was launched in 2019 by the Government of Pakistan. The idea of the initiative was to hold a competition between cities of Pakistan in cleanliness and greenery. A web portal was launched where citizens can get registered and report their activities to earn points. Citizens would also be awarded medals when they reach a certain threshold of points. Billion Tree Tsunami The Billion Tree Tsunami was launched in 2014 by the government of Khyber Pakhtunkhwa (KPK) as a response against the challenge of global warming. Pakistan's Billion Tree Tsunami restores 350,000 hectares of forests and degraded land
