Using energy, transport and other services more carefully to reduce emissions
People are adopting several strategies to tackle the pervasive impact of pollution, with a focus on reducing emissions from energy use, transport, and other services.
In the energy sector, there is a growing emphasis on pollution prevention, or P2, which aims to reduce or eliminate pollution at its source. This includes adopting cleaner energy sources, such as electric vehicles, and improving energy efficiency. For example, individuals are encouraged to use more efficient appliances and heating systems, turn off electrical devices when not in use, and switch to electric or hand-powered lawn equipment.
Transportation is a major contributor to greenhouse gas (GHG) emissions, with over 90% of transportation fuelled by oil. To address this, policies are being implemented to encourage shifts to less carbon-intensive travel options, such as walking, cycling, and public transport. There is also a growing emphasis on the electrification of transport, with major economies adopting policies to support the uptake of electric vehicles. The aviation industry is also exploring alternative jet fuels, such as green methanol and jet fuel made from captured CO2, to achieve net-zero emissions.
In addition to energy and transport, pollution prevention practices are being applied in other sectors. In the industrial sector, for instance, companies are modifying production processes to produce less waste, using non-toxic or less toxic chemicals, and implementing water and energy conservation practices. Similarly, in homes and schools, individuals are encouraged to use reusable water bottles and adopt other sustainable practices to reduce waste and pollution.
Overall, by carefully considering how we use energy, transport, and other services, we can significantly reduce emissions and work towards a pollution-free planet, as committed to by world environment ministers.

Governments adopting resolutions to target specific aspects of pollution
Governments have adopted resolutions targeting specific aspects of pollution, recognising their critical role in the fight against climate change. At the United Nations Environment Assembly (UNEA) in 2017, ministers of environment from around the world expressed their commitment to achieving a pollution-free planet. An Implementation Plan was devised to promote accelerated action and enhance capacities to address pollution, with a focus on several key areas:
Air Quality
Governments have implemented various measures to improve air quality and reduce air pollution. The US Environmental Protection Agency (EPA) plays a crucial role in regulating air emissions. The Clean Air Act, for instance, calls for state, local, federal, and tribal governments to collaborate in reducing air pollution. The EPA issues guidance and reviews state plans to ensure compliance with the Act. Additionally, the EPA's SmartWay program has helped companies transport goods more efficiently and reduce carbon dioxide and nitrogen oxide emissions.
Water Pollution
Water pollution is another area of focus for governments. Proper management and disposal of chemicals and waste are essential to reducing water pollution and achieving sustainable consumption practices.
Soil Pollution
Soil pollution has also been targeted by governments, with an emphasis on promoting sustainable agricultural practices and reducing the use of harmful chemicals and pesticides that can contaminate soil.
Marine Litter and Microplastics
The issue of marine litter and microplastics has gained global attention, with governments recognising the need to reduce plastic waste and improve waste management systems to prevent plastic pollution from entering our oceans.
Chemicals and Waste
Governments have also focused on the proper management and disposal of chemicals and waste more broadly, not just in the context of water and soil pollution. This includes promoting recycling, reducing food waste, and ensuring the safe handling and storage of hazardous materials.
Overall, these government resolutions demonstrate a commitment to addressing specific aspects of pollution and working towards a more sustainable future.

Industries using data to improve manufacturing processes and reduce emissions
The manufacturing industry is responsible for a significant proportion of global carbon emissions, with production sectors contributing one-fifth of carbon emissions and consuming 54% of the world's energy sources. As such, there is an urgent need for manufacturing companies to address the challenges of decarbonization.
One way to reduce emissions is to improve energy efficiency. This can be achieved through the use of smart meters and manufacturing analytics software, which help to monitor and manage energy usage. By identifying areas of excess energy usage, manufacturers can implement changes to reduce their carbon footprint and lower operational costs. Transitioning to renewable energy sources, such as wind, solar, and hydropower, can also dramatically reduce a manufacturing facility's carbon footprint.
Adopting lean manufacturing techniques, such as 5S, Kaizen, and Kanban, can help to streamline processes, reduce waste, and conserve energy and materials. This not only lowers the carbon footprint but also improves productivity and reduces costs. Using recycled and sustainably sourced materials can also reduce the environmental impact of manufacturing processes and promote a circular economy.
The application of new digital technologies, such as IoT devices, AI, and analytics software, can assist manufacturers in identifying areas for improvement. For example, optimizing transportation logistics through route planning and vehicle loading can reduce fuel consumption and emissions. Additionally, the use of intelligent manufacturing, as seen in China, has been shown to significantly reduce CO2 emissions by improving energy use efficiency and reducing fossil energy consumption.
Through data sharing, manufacturers can establish a baseline of carbon emissions and develop decarbonization initiatives. The World Economic Forum's initiative, Unlocking Value in Manufacturing through Data Sharing, aims to securely exchange Product Carbon Footprint (PCF) data along manufacturing and supply networks. This enables manufacturers to understand their carbon footprint and collaborate to address environmental challenges effectively.

Using less harmful pesticides and cultivating pest-resistant crops
The use of pesticides and the cultivation of crops have long been at the forefront of the fight against pollution. The traditional reliance on chemical pesticides to eradicate pests has led to various environmental and health issues, including pollution, and the development of pesticide-resistant pests.
To combat this, geneticists, agronomists, and farmers are working together to develop pest-resistant crops, leveraging a plant's built-in defense mechanisms to reduce the need for chemical interventions. This collaboration has resulted in the ongoing refinement of pest-resistant crops, ensuring they are more resilient to pests and cultivated in a way that supports the health of the planet. For example, the Rainbow papaya, a GMO crop, was developed to be resistant to the ringspot virus that threatened Hawaii's papaya industry. Similarly, a GMO eggplant developed to be insect-resistant has been introduced to farmers in Bangladesh since 2014, resulting in increased earnings and reduced exposure to pesticides.
Technologies such as nucleic acid extraction and pathogen detection are also being employed to identify naturally pest-resistant crops and keep up with the evolving pest landscape. Bioremediation is another approach that utilizes plants, algae, and microbes to remediate, reduce, or eliminate pesticide contaminants from the environment.
In addition to cultivating pest-resistant crops, adopting less harmful pesticides is another strategy to reduce pollution. For instance, biopesticides derived from nature, such as biochemical pesticides and plant-incorporated protectants, are natural substances that effectively manage pest populations without harming the environment or living creatures.
