Carbon Credits and Sustainable Development
### Summary of Article on Environmental and Carbon Credit Strategies #### Key Issues & Concepts: - **Growth Model and Environmental Limits**: The traditional growth model, rooted in the Industrial Revolution, risks surpassing planetary boundaries. Transitioning to a sustainable model is necessary, especially for developing nations facing poverty. - **Decoupling Growth from Pollution**: The focus should be on increasing economic growth without high pollution levels through cleaner technologies and sustainable practices. #### Carbon Credits: - **Definition**: A carbon credit signifies a certified reduction or removal of greenhouse gases, often used to offset emissions by firms transitioning to greener processes. - **Carbon Credit Trading Scheme (CCTS)**: India is establishing its own carbon market with emission-intensity benchmarks for energy-intensive sectors, including voluntary offsets. Draft methods for biomass, compressed biogas, and low-emission agriculture are in place. - **Global Market Trends**: Approximately 175 million to 180 million carbon credits are retired annually, mainly from renewable projects. #### Agricultural Projects and Challenges: - Only 4 out of 64 Indian agricultural projects under the Verra registry have issued credits due to weak engagement with farmers. - Rewards from carbon projects risk perpetuating exploitative power structures reminiscent of colonial practices. #### Case Studies: - **Northern Kenya Rangelands Project**: Launched in 2012, this project aimed for significant CO2 reduction but faced scrutiny for inadequate community consent and rights violations. The project was scrutinized for bypassing consent and affecting local land rights, leading to a suspension of credit issuance. - **Lake Turkana Wind Power Project**: Encroached on community grazing lands, raising concerns about sustainability versus local rights. #### Application to India: - Indian projects, particularly in afforestation and agriculture, might disrupt customary land use without community consent, echoing the challenges observed in Kenya. - Concerns regarding caste-based exclusions in benefit distribution from carbon projects have been raised. #### Recommendations: - **Community Rights and Benefit Sharing**: Emphasizing the protection of land rights and equitable distribution of benefits is crucial to avoid repeating colonial exploitation. - **Balanced Regulatory Framework**: India’s Carbon Credit Trading Scheme needs a transparent and participatory approach to safeguard community interests without imposing burdens. #### Conclusion: For effective climate action in India, stakeholder consultation and adaptive regulations are required to uphold justice in carbon markets. Failure to address these issues may replicate exploitative models under the guise of sustainability while marginalizing vulnerable groups. --- ### Constitutional and Legal Context: - No specific constitutional articles or legislative references were made in the article. ### Government Schemes and Policies: - Establishment of the Carbon Credit Trading Scheme (CCTS) aimed at setting emission-intensity benchmarks. ### Notable Economic Data: - An estimated market of approximately 175 million to 180 million carbon credits retired annually. ### International Agreements: - Reference to global carbon markets and the operation of the Verra registry for carbon credit projects. ### Science & Technology Updates: - Adoption of cleaner technologies for growth and sustainability; exploration of renewable energy and sustainable agricultural practices. ### Environmental Context: - Focus on sustainable methods of agriculture and renewable energy sources to mitigate climate change impacts. #### Final Note: These highlights underline the importance of integrating environmental justice with economic development, ensuring that all strata of society benefit from climate initiatives.

Challenges of Implementing Green Firecrackers
- **Supreme Court Ruling**: The Supreme Court lifted the blanket ban on firecrackers in Delhi-NCR, permitting the sale and bursting of only certified green firecrackers. The order aims to mitigate pollution during Deepavali. - **Challenges in Implementation**: Experts express concerns about the feasibility of enforcing this ruling due to limited time for traders to procure green firecrackers. Traders have less than three days to source the products, primarily from Tamil Nadu, which is facing logistical constraints. - **Historical Context**: A year-round prohibition on the production and sale of firecrackers in Delhi-NCR was reaffirmed by the Supreme Court in April, emphasizing the need for actions against pollution. - **Environmental Impact**: Environmental activist Bhavreen Kandhari criticized the short notice for enforcement, suggesting it will lead to continued breaches of the ruling. The concern is that despite the introduction of green firecrackers, the overall emissions might increase due to the overall volume of use during the festival. - **Statistical Insight**: - Out of 1,403 registered green firecracker manufacturers, 974 are based in Tamil Nadu. - Only one manufacturer exists in Delhi, while Uttar Pradesh has 51, and there are none in Haryana. This geographical concentration raises concerns about supply limitations impacting local enforcement and availability. - **Expert Opinions**: - Sunil Dahiya from Envirocatalysts warns that while green firecrackers emit 30% less pollution, the sheer volume used during festivals could lead to a net increase in emissions, counteracting any potential environmental benefits. - **Public Response and Conduct**: There have been instances of firecracker usage already noted during festivals like Dasara and Karwa Chauth, signifying ongoing challenges in public compliance with existing regulations. These points reflect crucial facts, figures, expert opinions, and legal contexts surrounding the Supreme Court's ruling on firecrackers, underlining both the environmental and enforcement concerns associated with the decision.
