Climate Change

Forests act as massive carbon sinks, absorbing carbon dioxide from the atmosphere through photosynthesis and storing it in biomass and soils. Tropical forests alone hold hundreds of gigatons of carbon, making their preservation one of the most cost-effective strategies available for limiting global warming.

Beyond carbon storage, forests regulate regional and global climate patterns through evapotranspiration, cloud formation, and the albedo effect. Healthy forest cover helps maintain rainfall patterns that support agriculture and freshwater systems across vast regions of the planet.

When forests are destroyed through logging or conversion to agriculture, the stored carbon is released rapidly into the atmosphere. Estimates suggest that deforestation and forest degradation account for roughly 10 to 15 percent of annual global greenhouse gas emissions, making forest conservation a central priority in any credible climate strategy.

International mechanisms such as REDD+ (Reducing Emissions from Deforestation and Forest Degradation) have been developed specifically to provide financial incentives for developing countries to protect their forests. These programs represent a vital bridge between global climate ambitions and on-the-ground conservation action.

The Paris Agreement, adopted in December 2015 at COP21, is a legally binding international treaty that commits nearly all nations to limiting global average temperature rise to well below 2 degrees Celsius above pre-industrial levels, with efforts to limit warming to 1.5 degrees. It replaced the earlier Kyoto Protocol as the primary framework for international climate cooperation.

Forest conservation plays a significant role within the Paris Agreement framework. Article 5 explicitly calls on parties to take action to conserve and enhance forests as carbon sinks and reservoirs. Countries are encouraged to implement REDD+ strategies and to pursue sustainable forest management as part of their nationally determined contributions.

The agreement also establishes a transparency framework that requires countries to report regularly on their emissions and the actions they are taking to reduce them. This is particularly important for forested nations, as it creates accountability for commitments related to deforestation rates and forest carbon stocks.

Since the Paris Agreement came into force, many tropical forest nations have included forest-related targets in their climate pledges. However, financing for forest conservation remains a critical challenge, as the scale of funding required to halt deforestation is far greater than what has so far been mobilised through public and private sources.

Developing countries face a profound injustice in the climate crisis: they have contributed least to cumulative greenhouse gas emissions yet bear the greatest burden of its consequences. Many are situated in tropical and subtropical regions where the physical impacts of climate change — more intense droughts, floods, storms, and heat — are already being felt most acutely.

These nations also tend to have economies that are more directly dependent on agriculture, fisheries, and natural resources, all of which are highly vulnerable to climate variability. A prolonged drought or a shift in rainfall patterns can devastate harvests, push communities into food insecurity, and undermine years of development progress.

The financial capacity to adapt to climate change is severely constrained in low-income countries. Building sea walls, drought-resistant crop varieties, early warning systems, and climate-resilient infrastructure all require substantial investment that many governments simply cannot afford. International climate finance pledges have repeatedly fallen short of what developing nations need.

Forest-dependent communities within these countries face additional layers of vulnerability. As climate change alters the distribution and health of forests, communities that rely on forest resources for food, medicine, and livelihoods face disruption to systems they have maintained sustainably for generations.

The United Nations Framework Convention on Climate Change (UNFCCC), established in 1992 at the Rio Earth Summit, serves as the foundational international treaty for global cooperation on climate change. It created the institutional architecture — including the Conference of the Parties (COP) — through which nearly all nations negotiate climate commitments and coordinate their responses.

The UNFCCC secretariat provides technical support and hosts negotiations that have produced landmark agreements including the Kyoto Protocol in 1997 and the Paris Agreement in 2015. COP meetings, held annually, are where governments review progress, negotiate new rules, and make decisions on issues ranging from carbon markets to climate finance to adaptation.

The UNFCCC process has also been the primary forum where REDD+ was developed and refined. Through a series of COP decisions over more than a decade, governments established the rules, safeguards, and monitoring requirements that govern how countries can receive results-based payments for reducing deforestation and forest degradation.

Critics of the UNFCCC process point to its consensus-based decision-making as a source of slow progress, since any party can block an agreement. However, defenders argue that this inclusive approach ensures broad legitimacy and that the framework has delivered meaningful, if insufficient, progress on one of the most complex multilateral challenges in history.

Carbon offsets are certificates representing a reduction or removal of one metric ton of carbon dioxide equivalent from the atmosphere. Companies or governments can purchase offsets to compensate for their own emissions that are difficult to eliminate immediately. Forest conservation projects have become a major source of carbon offset credits in both voluntary and compliance markets.

In forest-based carbon markets, project developers measure the carbon stored in trees and soils and calculate how much would be lost if the forest were converted to other uses. Credits representing the avoided emissions are then verified by independent auditors and sold to buyers seeking to offset their emissions. This creates a financial incentive for landowners to protect forests rather than clear them.

The integrity of forest carbon offsets has been a subject of considerable debate. Concerns include permanence (the risk that stored carbon will be released in future), additionality (whether the conservation would have happened without the carbon revenue), and leakage (whether protecting one area simply displaces deforestation elsewhere). Rigorous standards and monitoring are essential to address these challenges.

International frameworks, including Article 6 of the Paris Agreement, are now establishing rules for internationally transferred carbon credits. Getting these rules right is critical for ensuring that forest carbon markets deliver genuine climate benefits rather than simply allowing large emitters to avoid making the structural changes needed to decarbonise their operations.
