The Polluter Pays principle is a widely accepted environmental law principle that places liability for environmental harm on those responsible for it. At the same time, the global push towards Net Zero promises a future where emissions are balanced, if not entirely eliminated.
But what happens, when paying for pollution becomes a substitute for actual emission reduction? This question is becoming increasingly urgent especially in Africa and particularly in countries like Kenya which are emerging as key players in global carbon markets.
Understanding Legal Foundation
The Polluter Pays Principle is entrenched in international environmental law. Principle 16 of the Rio Declaration on Environment and Development (1992) states that:-
“….the polluter should, in principle, bear the cost of pollution, with due regard to the public interest….”
Net Zero, on the other hand, is a policy and scientific framework aimed at balancing greenhouse gas emissions with their removal. It is central to the 2015 Paris Agreement whose overarching goal as per Article 2 is to hold “the increase in the global average temperature to well below 2 Degree Celsius above pre-industrial levels” and pursue efforts “to limit the temperature increase to 1.5 Degree Celsius above pre-industrial levels.”
Together, Polluter Pays Principle and Net Zero are supposed to drive accountability and climate action. In theory, the Polluter pay principle ensures polluters bear the cost of environmental harm. In practice, however, their interaction raises a critical concern especially when Paying Replaces Reducing emissions. That means if left unchecked, it can create a system that merely places a ‘price tag’ on pollution rather than acting to prevent it thus allowing companies to continue emitting greenhouse gases, purchase carbon credits elsewhere and claim carbon neutrality without significantly changing their operations.
Africa’s Position
According to the African Development Bank Group, Africa contributes less than 4% of global greenhouse gas emissions yet it faces some of the most severe climate impacts ranging from prolonged droughts to flooding and food insecurity. At the same time, African countries are increasingly being positioned as carbon sinks, offset destinations and hosts of climate mitigation projects funded by foreign corporations.
Kenya for example, has become a hub for carbon credit projects, including land-use and non-land use initiatives. While these projects can bring investment and environmental benefits, without strong governance, carbon markets risk reinforcing inequality and raising serious legal and ethical questions such as:-
Who owns the carbon rights?
Was meaningful public participation and consultations carried out?
How are benefits being shared?
What happens to land rights and existing livelihoods?
Therefore, incorporating Africa into this conversation is not just about inclusion it is about redefining accountability in a way that reflects global realities. This means the Polluter Pays Principle needs to move towards paying for restoration, resilience and a just transition.
Moving beyond “Paying to Pollute”
In Africa, if the Polluter Pays Principle is to remain relevant in the era of Net Zero, it must evolve from a purely economic tool into a mechanism for genuine environmental accountability. This means:-
- Prioritizing Emission Reductions
Companies must be required to reduce emissions at source, not simply offset them. For instance entities such as Nestle with a commitment to achieving Net Zero by 2050, are investing in reducing the carbon footprint through regenerative agriculture where they invest in farming practices that improve soil health, reduce deforestation and restore ecosystems. Concerning their supply chain, they are sourcing raw materials like corn and cocoa from farms utilizing sustainable methods. They are also working on production efficiency which is expected to reduce energy consumption in manufacturing and increase the use of renewable energy.
- Strengthening Monitoring and Enforcement Mechanisms
To prevent the principle from being symbolic, African countries need to ensure stronger monitoring and enforcement mechanisms for carbon markets. Several African countries such as Kenya and South Africa have moved beyond symbolic commitments and have enacted specific laws to monitor and enforce carbon market standards.
For instance, Kenya has enacted the Climate Change Act Cap. 387A and its enabling regulations such as the Climate Change (Carbon Markets) Regulations, 2024 to regulate carbon markets in Kenya. It has also operationalized the National Carbon Registry, a digital ledger used to track, authorize and report all carbon market activities to prevent double counting. It has also designated the National Environment Management Authority (NEMA) as the body responsible for monitoring registered carbon projects and ensuring compliance with international standards. South Africa on the other hand, utilizes a compliance-based approach through its Carbon Tax Act of 2019 which imposes tax on entities in the country that produce greenhouse gas emissions at a rate that is equal to or above the carbon tax by allowing the said companies to measure, report and buy recognized carbon credits to offset tax liabilities.
- Centering Climate Justice and Equity
Climate justice means putting equity and human rights at the core of decision-making and action on climate change. Therefore, climate negotiations and plans must reflect equity and transparency by ensuring that those least responsible for climate change are not disproportionately burdened by its solutions. In addition, an evolution of the Polluter Pays Principle must ensure that major emitters bear a fair share of adaptation and loss and damage costs in Africa.
On the other hand, financing mechanisms tied to the Polluter Pay Principle should allocate substantial resources toward climate-resilient infrastructure, agriculture, water systems and disaster preparedness across the continent. This will ensure that African countries are not only mitigating climate change but also prioritizing climate adaptation. Also, funds generated through carbon credits should be used to empower national and local governments, civil societies and communities to design and implement context-specific solutions thus reducing dependency and improving accountability while also strengthening local ownership and governance.
- Supporting green development pathways
Africa should not be forced to choose between development and sustainability, both should go hand-in-hand. Therefore, African Governments must ensure that revenues and policies linked to the Polluter Pays Principle actively support clean energy transitions, sustainable industrialization and job creation across the continent.
Conclusion
The climate crisis cannot be solved through financial transactions alone. While the Polluter Pays Principle is essential, it is not sufficient. Paying for pollution is not the same as preventing it. Therefore, as Net Zero continues to be a global benchmark, we must ask harder questions, not just about who pays but about who is reducing the emissions. Ultimately, the goal should be reduction of emissions thus making pollution both unacceptable and costly.
