Literature Review: Global Climate Change Best Practices in Mitigation and Adaptation

This literature review explores the best practices in climate change mitigation (reducing greenhouse gas emissions) and adaptation (adjusting to climate impacts). It draws from a variety of sources, including government policies, corporate sustainability programs, and community-based solutions.

1. Government Policies in Climate Change Mitigation and Adaptation

A. Mitigation Strategies:

1. Carbon Pricing (Carbon Taxes and Cap-and-Trade)
   • Carbon Pricing has emerged as a central strategy for reducing greenhouse gas emissions by making fossil fuel use more expensive. Governments in countries such as Sweden, Canada, and the European Union have adopted carbon taxes or cap-and-trade systems.
   • Sweden’s Carbon Tax: Sweden has implemented one of the highest carbon taxes globally, which has helped the country achieve a significant reduction in emissions per capita without compromising economic growth. It is often cited as a model of effective carbon pricing.
   • EU Emissions Trading System (ETS): The EU ETS is the world’s largest carbon market, incentivizing emission reductions by placing a cap on total emissions and allowing market-based trading of allowances.
2. Renewable Energy Adoption
   • Governments worldwide are promoting renewable energy through subsidies, tax credits, and renewable portfolio standards (RPS). Germany’s Energiewende is a key example of a comprehensive policy aiming to transition the country toward 80-95% renewable energy by 2050.
   • China’s Renewable Energy Policy: China is the world’s largest investor in renewable energy, particularly in solar and wind. The government has provided incentives such as feed-in tariffs and renewable energy quotas to encourage renewable energy generation.
3. Energy Efficiency Standards
   • Building Codes and Appliance Standards: Many countries have implemented stringent energy efficiency standards for buildings, appliances, and vehicles. California’s Title 24 energy efficiency standards are among the most stringent in the world, leading to significant reductions in energy consumption.
   • The International Energy Agency (IEA) promotes policies that require the development of low-carbon technologies and energy efficiency measures.
4. National Climate Action Plans (NDCs)
   • Under the Paris Agreement, countries have committed to Nationally Determined Contributions (NDCs), which are their voluntary climate action plans. Countries like Costa Rica have set ambitious goals to become carbon neutral by 2050.
   • Bhutan, which is carbon negative, has successfully implemented policies to preserve forests, which act as carbon sinks, and promote sustainable development.

B. Adaptation Strategies:

1. Disaster Risk Reduction and Resilience Building
   • Governments, particularly in developing countries, are focusing on disaster risk reduction (DRR) to build resilience to climate change. Bangladesh has implemented early warning systems and flood shelters to protect populations from extreme weather events like floods and cyclones.
   • Japan’s Disaster-Resilient Infrastructure: Japan’s earthquake and tsunami resilience strategies, including flood defenses and seismic-resistant buildings, can serve as models for coastal and flood-prone regions worldwide.
2. Climate-Resilient Infrastructure
   • Singapore has implemented policies to make its infrastructure climate-resilient, including water management systems designed to withstand rising sea levels and extreme weather events.
   • Netherlands’ Delta Works: The Netherlands is a pioneer in flood protection systems, particularly the Delta Works, a series of dams, sluices, locks, dikes, and storm surge barriers to protect low-lying areas from flooding.
3. Ecosystem-Based Adaptation
   • Governments are increasingly adopting nature-based solutions, such as wetland restoration and mangrove protection, to mitigate and adapt to climate change impacts.
   • The Philippines has invested in coastal ecosystem restoration, recognizing the role of mangroves in protecting coastal communities from typhoons and storm surges.

2. Corporate Sustainability Programs

A. Mitigation Strategies:

1. Corporate Carbon Neutrality
   • Several corporations, such as Google and Microsoft, have committed to becoming carbon-neutral. These companies achieve this through a combination of reducing their own emissions and purchasing carbon offsets.
   • Unilever’s Sustainable Living Plan: Unilever has integrated sustainability into its business model, aiming to reduce greenhouse gas emissions from its operations and supply chains.
2. Renewable Energy Integration
   • Apple has committed to running its entire global business on 100% renewable energy and has achieved this target for its global facilities.
   • Walmart has set a goal to become 100% powered by renewable energy by 2035 and has already made significant strides by investing in solar and wind energy.
3. Sustainable Supply Chains
   • Many corporations are working with suppliers to reduce emissions and waste. Nike’s Move to Zero initiative aims to achieve zero carbon and zero waste in its supply chain by innovating with sustainable materials and production processes.
   • Patagonia’s Commitment to Sustainability: Patagonia has committed to ensuring that its supply chain minimizes environmental impact, and it promotes the use of recycled materials in its products.

B. Adaptation Strategies:

1. Climate Resilience in Operations
   • Coca-Cola has implemented water stewardship initiatives in regions vulnerable to water scarcity, focusing on efficient water use and replenishment in areas where they operate.
   • Dow Chemical has integrated climate risk assessments into its operational strategy, helping to adapt manufacturing processes and facilities to extreme weather events and water risks.
2. Building Resilience through Community Engagement
   • Many corporations, including Nestlé and PepsiCo, are implementing community-based programs that support resilience to climate impacts, such as improving water access, agriculture, and sustainable livelihoods.
   • Coca-Cola’s 5by20 Program: This initiative aims to empower 5 million women entrepreneurs by 2020, helping them build resilience through entrepreneurship, training, and community engagement.

3. Community-Based Solutions

A. Mitigation Strategies:

1. Local Renewable Energy Solutions
   • Solar Home Systems in Rural Africa: In countries like Kenya and Tanzania, rural communities are adopting solar-powered microgrids and home solar systems, enabling energy access while reducing reliance on traditional fossil fuels.
   • India’s Solar Microgrids: In rural India, the government and NGOs have helped establish solar-powered microgrids that are reducing carbon emissions while providing clean electricity to remote villages.
2. Waste-to-Energy Initiatives
   • In Colombia, communities in Bogotá have implemented waste-to-energy projects, converting organic waste into biogas to generate electricity.
   • Nepal’s Biogas Program: Nepal has successfully implemented biogas systems for rural households, providing both cooking fuel and reducing carbon emissions.

B. Adaptation Strategies:

1. Community-Based Disaster Risk Management
   • The Community-Based Adaptation (CBA) approach empowers local populations to design and implement their own adaptation strategies. For example, Vanuatu has used a participatory approach to build disaster-resilient homes and community infrastructures in coastal areas.
   • In Ethiopia, the government has supported the development of climate-resilient agricultural practices like drought-resistant seeds and water-efficient irrigation systems.
2. Ecosystem-Based Adaptation
   • Kenya’s Community-Driven Mangrove Restoration: Coastal communities in Kenya have worked with conservation NGOs to restore mangrove ecosystems, which provide protection against coastal erosion, storm surges, and flooding.
   • India’s Coastal Greenbelt Program: This initiative, led by local communities, has focused on restoring and preserving mangrove forests along India’s coastline to reduce the impacts of rising sea levels.

4. Key Findings and Synthesis

Government Policies: Governments worldwide are increasingly recognizing the importance of both mitigation and adaptation. Policies that integrate carbon pricing, renewable energy promotion, and disaster risk reduction are proving effective. However, more global cooperation is necessary to meet climate goals.

Corporate Programs: Businesses are increasingly adopting sustainable practices and taking bold steps toward carbon neutrality. These initiatives not only reduce emissions but also create new markets and opportunities in the green economy.

Community-Based Solutions: Local-level strategies, particularly those that incorporate community engagement and nature-based solutions, are crucial for building long-term resilience. Communities must be empowered to take ownership of adaptation and mitigation efforts.
